Description
DETAILED DESCRIPTION OF THE INVENTION
[0078] Embodiments of the present invention will now be described, by way of examples only and with reference to the following figures.
[0079]

[0081]
EXAMPLE 1ADMINISTRATION OF LACTOBACILLUS PLANTARUM ECGC 13110402
[0082] A human volunteer study was conducted to establish the safety, compliance and extent of cholesterol reduction and hypertension control by administering compositions comprising Lactobacillus plantarum ECGC 13110402 to 49 mildly hypercholesterolaemic adults. The study was carried out independently by the Department of Food and Nutritional Sciences at the University of Reading, UK. The study was carried out according to the Helsinki declaration and written informed consent was obtained from all volunteers. The study protocol was approved by the Research Ethics committee of the University of Reading.
[0083] Subjects were male or female, aged 30-65 years. Subjects were excluded if they had had a previous cardiovascular event within the last 6 months, if secondary dyslipemias related to thyroid dysfunction were present, if they had used any drug affecting lipid metabolism in the previous 3 months, if they had a history of alcohol abuse, if they had taken antibiotics in the previous 6 months or if they had taken prebiotics/probiotic preparations in the last month.
[0084] Those who met the inclusion criteria were screened prior to the commencement of the study. A baseline blood sample was taken and their BMI and blood pressure were measured. The screening blood sample was analysed for full blood count (FBC) and liver function tests (LFTs) to determine overall health. Total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C), fasting triacylglycerol (TAG) and vitamin D were also measured. Urine, blood and faeces were collected for bile acid and metagenomic and metabolomics studies.
[0085] The study was a single-centre, prospective, randomized, double-blind, placebo-controlled, parallel-group trial. Subjects were randomly distributed into two groups: placebo or treatment with Lactobacillus plantarum ECGC 13110402. The placebo and treatment groups were provided with a blister packed DR 1 capsule. The treatment group received 120 mg of active Lactobacillus plantarum ECGC 13110402 providing a dose of 1.810.sup.9 cells per capsule which was administered once or twice daily; once at breakfast and once in the evening as a dietary supplement. Participants were advised not to change their regular diet or physical activity throughout the trial period. Habitual diet was assessed by pre-validated 5-day food diaries (2 weekend and 3 week days).
[0086] Formulation details for the active and placebo formulations respectively are shown in tables 1 and 2 below:

[0087] Volunteers were pre-screened 2 weeks prior to the study start and were advised to refrain from any pre/probiotic intake. The study consisted of two phases: a treatment period (12 weeks) and a wash-out period (4 weeks). The study included a baseline visit at selection, a visit at the midpoint and at the endpoint of the treatment period (weeks 0, 6 and 12, respectively), and a fourth visit after the wash-out period (week 16).
[0088] An initial set of analyses examined the demographic and outcome variables at baseline to ensure that the two groups were well matched. Continuous variables were analysed using the unpaired t-test, whilst the Chi-square test was used for the categorical variables.
[0089] Study outcomes between the two study groups were analysed in terms of changes between timepoints. Four study periods were examined for changes in outcomes: baseline to midpoint (0-6 weeks), midpoint to endpoint (6-12 weeks), baseline to endpoint (0-12 weeks) and endpoint to washout (12-16 weeks). Data for each analysis was restricted to the particular two timepoints in the analysis. The analyses were performed using analysis of covariance (ANCOVA). The latter timepoint was used as the outcome variable, with the earlier timepoint considered as a covariate. This approach is mathematically preferable to simply comparing the change over time between groups, as it takes into account the variable starting values for the test and control group. The first set of analyses considered all study participants and different patient subgroups. These subgroups were based on baseline total cholesterol (<5 mmol/l, 5-5.9 mmol/l and 6.0 mmol/1), gender and age (<50 yrs, 50-59 yrs, 60 yrs).
[0090] There were no safety, compliance, or tolerance issues reported by volunteers throughout the study. Three volunteers dropped out of the study due to antibiotic treatment for non-related illnesses which excluded them from further study participation.
[0091] Volunteers were asked to fill in daily gastrointestinal symptom diaries throughout the duration of the study and to report any adverse effects experienced. GI symptoms for abdominal pain, bloating and flatulence were recorded by volunteers as none (0), mild (1), moderate (2) or severe (3). As illustrated in Table 3 below, average scores of self-reported gastrointestinal (GI) symptoms from baseline to 12 weeks showed no significant difference in bowel movements per day or stool consistency (Bristol stool chart) between the groups. One volunteer in the active group reported moderate abdominal pain, bloating and flatulence, while in the placebo group two volunteers reported moderate flatulence. None of the study participants reported severe GI side effects during the baseline to 12 week treatment period and no significant differences in stool morphology and frequency were observed between treatment groups. All other volunteers reported no symptoms.
TABLE-US-00003 TABLE 3 Placebo Active Average SD Average SD Bowel movements 1.28 0.53 1.27 0.51 Stool consistency 3.35 1.25 3.55 0.90 Abdominal pain 0.15 0.18 0.32 0.47 Bloating 0.28 0.31 0.35 0.49 Flatulence 0.68 0.44 0.53 0.48
[0092] The baseline characteristics (total cholesterol, anthropometric measurements, systolic and diastolic pressure) were compared between the placebo (n=23) and active (n=23) groups and are shown in table 4 below. The results suggested no significant difference between the two study groups in terms of their demographics (age, sex) or for any of the lipid or anthropometric measures at baseline.
TABLE-US-00004 TABLE 4 Placebo (n = 23) Active (n = 23) Variable Mean (SD) Mean (SD) P-value Age 52.0 (8.4) 52.3 (10.7) 0.89 Gender: Female 14 (61%) 18 (78%) 0.20 Gender: Male 9 (39%) 5 (22%) Total cholesterol 5.22 (0.92) 5.10 (0.71) 0.62 HDL cholesterol 1.24 (0.31) 1.40 (0.35) 0.10 LDL cholesterol 3.44 (0.76) 3.20 (0.68) 0.28 Triacylglycerides 1.18 (0.45) 1.11 (0.46 0.61 Weight 79.2 (16.5) 72.1 (12.0) 0.10 BMI 26.8 (5.0) 26.7 (3.7) 0.96 Waist 92.3 (13.5) 89.6 (12.0) 0.49 Systolic BP 118.7 (16.0) 119.2 (13.2) 0.73 Diastolic BP 71.0 (12.2) 73.0 (8.0) 0.52
[0093] Independent statistical analysis was performed to examine how the changes in lipid measurements over the course of the study varied between the two study groups. Changes between four pairs of time points (0-6 weeks; 0-12 weeks; 6-12 weeks; 12-16 weeks) were examined. Only analysis of data between baseline and end of treatment (0-12 week) is shown unless otherwise indicated. Clinically or statistically significant variations between other timepoints are highlighted.
[0094] Tables 5-7 below show the mean and standard deviation at baseline and the end of treatment at 12 weeks. Table 5 shows the changes in lipid measurements for all subjects (n=46) from baseline to 12 weeks. Table 6 shows the changes in lipid measurements for subjects with TC of <5 mmol/l (n=23) from baseline to 12 weeks. Table 7 shows the changes in lipid measurements for subjects with TC of 5-5.9 mmol/l (n=17) from baseline to 12 weeks. Analyses was carried out for 6.0+ mmol/l but as this group only contained 6 subjects (3 active, 3 placebo) only statistically significant differences are reported, with appropriate caveats.
[0095] The group differences from the ANCOVA analyses are reported, with the mean difference and corresponding confidence interval. These are reported as outcome for active group minus outcome for placebo group adjusting for the baseline value. P-values indicating the significance of the results are reported.
[0096] TC, LDL-C, HDL-C and TAG concentrations are expressed in mmol/1.
[0097] The groups were stratified according to baseline cholesterol levels as shown in tables 5-7 and according to age (<50 years n=16; 50-59 years n=18; 60 years, n=12) and gender (female=32, male n=14).

[0098] Total cholesterol (TC) from baseline to 12 weeks was reduced in all groups compared to the placebo group (Tables 5-7). The baseline adjusted value for TC levels in all subjects was 0.12 mmol/l lower in the active group compared to the placebo group, a 2.3% decrease. Stratification according to baseline TC concentrations revealed variations between the higher TC and medium to low subgroups. In the TC<5.0 mmol/l subgroup the change between baseline and end of treatment was 4.2% lower in the active compared to the placebo group (0.19 mmol/l lower). Similarly in the TC 5-5.9 mmol/l group, the baseline adjusted end of treatment TC concentrations were 0.23 mmol/l lower in the active group, corresponding to a 4.17% reduction. In the TC6.0 mmol/l (0-6 weeks) group a statistically significant reduction in TC of 2.44 mmol/l was observed, corresponding to a 36.7% reduction (P=0.045) (data not shown in tables 5-7). However, the size of this group was very small (n=3 placebo/3 active) and so despite its statistical significance no group relevance should be attributed to this effect. No significant effect of gender on TC was identified. Although most results were not of statistical significance, there was a common group trend for a decrease in TC in the active treatment groups when compared to the placebo. The results also suggested that patients with higher initial levels of TC may benefit from higher reductions in TC than others.
[0099] HDL-C increased slightly between baseline and 12 weeks for both placebo and active groups. On adjusting for variable baselines the HDL-C concentrations for the all subject and TC<5 mmol/l group were 0.06 mmol/l (4.5%) and 0.09 mmol/l (7.4%) higher in the active group when compared to the placebo. Most of this difference occurred in the 6-12 week period where differences approaching statistical significance were seen for both all subject (p=0.06) and TC<5 mmol/l groups (p=0.09). The all subject and TC<5 mmol/l groups in this period showed average increases in HDL cholesterol levels of 0.09 mmol/l (6.5%) and 0.10 mmol/l (7.8%) respectively when compared to the placebo group.
[0100] Age stratification revealed statistically significant group differences (p=0.03) in the 60+ group (n=12) who had average increases in HDL cholesterol of 0.23 mmol/l (+14.7%) when compared to the placebo group. Stratification according to baseline TC concentrations and gender revealed no significant treatment effect on HDL levels.
[0101] LDL-C cholesterol reduced between baseline and 12 weeks in all the active treatment groups. This effect was not observed in the placebo group.
[0102] Upon adjusting for variable baselines, LDL-C concentrations for the all subject groups were on average 0.24 mmol/l (7.2%) lower when compared to placebo. LDL-C concentrations in the TC<5.0 mmol/l group were significantly lower by 0.39 mmol/l (13.9%) in the active compared to the placebo group (P=0.03). These reductions have clinical and commercial significance. In the TC 5.0-5.9 mmol/l group, LDL-C showed an average 0.47 mmol/1 decrease (13.1%), but this did not reach statistical significance. The LDL reducing effect appeared to occur consistently across both the 0-6 and 6-12 week periods. The results suggest patients with higher initial levels of LDL cholesterol may benefit from higher reductions in LDL-C than others.
[0103] Stratification according to gender revealed a more pronounced LDL-C reducing effect in female volunteers compared to males (p=0.06). Active group concentrations were 0.41 mmol/l (12.4%) lower for females compared to placebo while a 0.06 mmol/l (1.8%, P=0.06) increase was observed for the active male group compared to placebo (P=0.83).
[0104] Stratification according to age showed higher decreases in LDL-C concentrations with increasing age. Only slight changes were observed in the baseline adjusted LDL-C concentrations in the <50 years group (0.08 mmol/l increase). LDL-C decreases were more pronounced in the 50-59 group (0.49 mmol/1) and in the 60 years group (0.31 mmol/l), corresponding to a 15% and 9.14% decrease respectively in the active group compared to the placebo.
[0105] No significant effects on triacylgyceride concentrations were observed upon the ingestion of either the active or placebo treatments in the all subjects, TC=<5 mmol/1, or TC 5-5.9 mmol/l groups. Age stratification showed a statistically significant (p=0.002) triglyceride reduction in the 60+ group of 0.48 mmol/l (53.9%) between the placebo and active group. This large reduction in triglycerides was consistent across all testing time periods with a statistically significant reduction (p=0.03) of 0.26 mmol/l (32.9%) in the 6-12 week period and a reduction of 0.28 mmol/l (31.4%, p=0.07) in the baseline to 6 week period.
[0106] Changes in anthropometric measurements for all subjects (n=46) in the placebo and active treatment groups are shown from the baseline to the end of treatment after 12 weeks in table 8 below. The mean values and standard deviation for each measured outcome at baseline and after 12 weeks are shown in table 8. Group differences from the ANCOVA analyses are also shown with the mean difference and corresponding confidence interval. These are reported as outcome for active group minus outcome for placebo group adjusting for the baseline value. P-values indicating the significance of the results are reported. Body weight is expressed in kg, BMI in kg/m.sup.2, waist circumference in cm and systolic/diastolic pressure in mmHg.

[0107] No significant changes were noted in the anthropometric parameters relevant to weight, BMI and waist circumference between baseline and end of treatment at 12 weeks.
[0108] There was group evidence of a difference in systolic and diastolic blood pressure between baseline and 12 weeks. The difference in systolic blood pressure was both statistically and clinically significant. In the all subject active treatment group systolic blood pressure was 3.6 mmHg lower (3%) whilst diastolic pressure was reduced by 1.6 mmHg (2.2%). The majority of the reduction in systolic blood pressure occurred in the 6-12 week time period. This showed a statistically significant reduction (P=0.003) in systolic blood pressure of 6 mmHg (5.1%) in the active group when compared to the placebo group (data not shown in table 4). This is higher than the mean 3 mmHg pulse pressure reduction achieved by ACE inhibitors, ARBs and renin inhibitors and the 2 mmHg pulse pressure reduction with non-selective beta blockers. This reduction is also greater than the reduction of systolic BP by 3.56 mm Hg (95% confidence interval, 6.46 to 0.66) compared with control groups shown in a study analysing blood pressure reduction by probiotics (Khalesi et al, 2014).
[0109] The results show that Lactobacillus plantarum ECGC 13110402 has the potential to lower systolic blood pressure, blood TC and LDL-C in at least mildly hypercholesterolaemic subjects. These results, in an unoptimised product, suggest efficacy similar or greater to 1.5-2.4 g plant sterols/stanols per day.
[0110] Active Lactobacillus plantarum ECGC 13110402 and placebo capsules were stored at 4 C. throughout the study duration. Product stability was checked at baseline, 6 weeks and 12 weeks (end of treatment) of the study and no significant change was observed in bacterial numbers. No bacterial growth was detected in the placebo capsules.
[0111] Analysis of safety parameters did not show deleterious effects of consuming Lactobacillus plantarum (ECGC 13110402). Lactobacillus plantarum is a widely used probiotic which is considered Generally Regarded as Safe (GRAS) by the US Food and Drug Administration (FDA) and has a Qualified Presumption of Safety (QPS) designation by the European Food Standard Agency. This would suggest that Lactobacillus plantarum ECGC 13110402 has the potential to be a safe and effective treatment for the treatment of hypercholesterolemia and hypertension.
[0112] Industrial scale-up experiments were also conducted on Lactobacillus plantarum ECGC 13110402. The following activities were performed: a) testing of flasks for different hypoallergenic media; b) fermentations of 1-5 L, concentration and freeze drying of small amounts to study; c) testing of different cryoprotectants; d) testing of different freeze drying curves; e) fermentation in 80 L, concentration and freeze drying. The final step was a production in a 80 L fermenter which resulted in: (i) cell count >810.sup.11 cfu/g; (ii) Aw: 0,11; (iii) a quantity of 700 g of concentrated biomass, freeze dried and not diluted/standardized with any excipient. Therefore, this particular strain looked extremely promising from a manufacturing point of view. Survival rate of the cells was found to be at more than 70% and yields were at 1.25% which is extremely high.
EXAMPLE 2THE EFFECT OF PURIFIED LACTOBACILLUS PLANTARUM ECGC 13110402 GOS ALONE AND in Combination with Lactobacillus plantarum ECGC 13110402 on the Human Faecal Microbiome
[0113] The effect of purified L. plantarum ECGC 13110402 GOS (LPGOS) alone and in combination with L. plantarum ECGC 13110402 (LP) on the human faecal microbiome was evaluated in anaerobic, pH and temperaturecontrolled, micro scale batch cultures in the presence of cholesterol. Purified, commercially available bifidobacterial GOS (BGOS) was used as a positive control.
Micro scale faecal batch cultures (10 ml) testing in parallel: Faeces; Faceses+LP; Faeces+LPGOS; Faeces+LPGOS+LP; Faeces+BGOS; and Faeces+BGOS+LP.
[0114] Cultures (24 h) were run in triplicate, using faeces from each of three healthy adults. Samples were obtained for bacteriology (FISH), metabolite, BSH activity and cholesterol reduction determination.
[0115] As illustrated in
[0116]
[0117] As illustrated in
[0118] In these experiments, it was found that using -galactosidases expressed by L. plantarum ECGC 13110402 achieved the synthesis of GOS that works in true synergy with the parent strain, not only increasing its population but also impacting on the biological activity for which the probiotic was selected. The results of these experiments show that the presence of a prebiotic increases growth, increases BSH activity, and enhances cholesterol reduction by up to 3 times.
EXAMPLE 3ACTIVE INGREDIENTS
[0119] A number of active ingredients which have been shown to modify cholesterol may be combined with Lactobacillus plantarum ECGC 13110402.
Inclusion Criteria for Active Ingredients
[0120] Some of the active ingredients should be a food or a food derived ingredient for which there is evidence of well proven efficacy on the primary endpoint measure, serum LDL-cholesterol (LDL-C), from randomly controlled intervention trials in humans. Beneficial effects on secondary endpoints of cardio-metabolic risk, such as energy intake, glucose homeostasis, dyslipidaemia, blood pressure and vascular dysfunction, would be an advantage. The compound must be safe and tolerable for human consumption, and have a viable route of delivery to its site(s) of action (e.g. gut and/or peripheral tissues). In relation to effect on primary and secondary endpoints, its mechanism(s) of action should complement that of Lactobacillus plantarum ECGC 13110402.
[0121] Most of the compounds under address have an accepted health claim through European Food Safety Agency (EFSA), and comply with their criteria for the substantiation of a health claim in at least one case. The EFSA criteria is that the compound should benefit human health; there should be evidence of a cause and effect relationship on basis of the strength, consistency, specificity, dose-response and biological plausibility of the relationship. The quantity of the compound and its pattern of consumption required to obtain the claimed effect must be achievable within a balanced diet, and the specific study group in which the evidence was obtained must be representative of the target population for which the claim is intended.
Background Information of Selected Compounds
[0122] Some of the selected compounds can be categorised into non-digestible carbohydrates (dietary fibres), plant-derived polyphenols (phytosterols and stanols), and a polykelide (monocolin K). These compounds produce what is classified by the NICE guidelines as a low intensity reduction in serum LDL-C of between 20-30%. Their modes of action are mostly in the gut, and thus non-systemic, with the exception of monocolin K.
Statins
[0123] Statins are a class of lipid-lowering medications that inhibit the enzyme HMG-CoA reductase and are used to control cholesterol levels in individuals. The National Institute for Health and Care Excellence (NICE) in the UK has provided guideline on dosage for satins. Statins are grouped into 3 different intensity categories according to the percentage reduction in low-density lipoprotein cholesterol: [0124] Low intensity (20-30% LDL-C reduction): [0125] fluvastatin 20-40 mg daily [0126] pravastatin 10-40 mg daily [0127] simvastatin 10 mg daily. [0128] Medium intensity (31-40% LDL-C reduction): [0129] atorvastatin 10 mg daily [0130] fluvastatin 80 mg daily [0131] rosuvastatin 5 mg daily [0132] simvastatin 20-40 mg daily. [0133] High intensity (more than 40% LDL-C reduction): [0134] atorvastatin 20-80 mg daily [0135] rosuvastatin 10-40 mg daily [0136] simvastatin 80 mg daily.
All of these medicaments have been clinically proven to reduce cholesterol.
Plant/Phyto Stanols and Sterols
[0137] As food ingredients, phytosterols are esters of plant derived -sitosterol, while phytostanols are esters of sitostanol and campestanol obtained from the reduction of the respective plant sterols from food grade plant oils (e.g. soybean). Both compounds have equivalent and well established efficacy in lowering serum LDL-C in mild hypercholesterolaemia, with an intake of 2-3 g/d achieving a mean reduction in serum LDL-C of 7-10% in a matter of weeks to months in meta-anlyses. This effect has been demonstrated in a range of food matrices, including low fat products. There is some evidence of secondary health benefits on markers of inflammation, blood clotting and some cancers. The difference between phytosterols and stanols is that the former are absorbed (then re-secreted by efflux transporters in the enterocyte ABCG5 & G8) to a significantly greater extent than phytostanols (0.5-2% versus 0.04-0.2% respectively versus dietary and biliary cholesterol 55%). The LDL-lowering effect is mediated through two mechanisms; competition with dietary and biliary cholesterol for uptake and solubilisation into mixed micelles, and via the down-regulation of the Niemann Pick-C1-L1 transporter, both of which reduce the uptake of cholesterol into the enterocyte. This non-systemic reduction in the absorption of dietary (0-0.5 g/d) and biliary cholesterol (1 g/d) limits cholesterol supply, chiefly to the liver, depleting intra-cellular free cholesterol. This promotes a compensatory up-regulation of LDL-receptor gene expression and activity, and the removal of circulating LDL into cells. Health claims and recommendationsEFSA states that plant sterols and stanols help in the management of normal cholesterol levels (ID 549, 550, 567, 713, 1234, 1235, 1466, 1634, 1984, 2909, 3140), and that a cause and effect relationship has been established between these compounds and the lowering of serum LDL-C. ATP-III guidelines in the USA state that phytosterols and stanols should be recommended for the long term management of hypercholesterolaemia, and as a useful adjunct to statin therapy in the reduction of CVD risk. Safety and toleranceThe main safety issue concerns a reduction in the absorption of fat soluble vitamins, and for this reason phytosterols and stanols are contraindicated in pregnant and breast feeding women, and children under 5 years. They are also contraindicated for individuals with a rare inherited condition of sitosterolaemia who have a mutation in their cholesterol efflux transporters (ABCG5/G8) and thus an inability to re-secrete absorbed plant sterols which leads to their accumulation in cells and the artery wall. There is limited evidence to suggest that small numbers of individuals without this rare condition may also accumulate sterol esters and are thus at increased CVD risk.
[0138] A review of stanols and sterols by the EFSA concluded that free (unesterified) stanols and sterols at doses of 1.5 g-1.9 g and 2.0 g-2.4 g per day lowered blood LDL-cholesterol by an average of 8.5% and 8.9% respectively (The EFSA Journal (2009) 1175, 1-9). However, studies (Katan M B, et. al., (2003) Mayo. Clin. Proc. 78, 965-978) have also showed that lower doses of stanols and sterols at 0.7 g-1.1 g per day reduced LDL-cholesterol by 6.7% and higher doses at over 2.5 g per day reduced LDL-cholesterol by 11.3%.
[0139] Phytosterols (added as free or esterified sterols) have been incorporated into appropriate foods such as milk and yoghurt. Plant stanol esters have also been added to foods (mainly margarine type spreads but also including yoghurt, mayonnaise, gel capsules, butter, low fat cheese, milk, muesli, ready-made low fat meals, and pasta)
Monacolin K in Red Yeast Rice
[0140] Stains are the first line treatment for the management of hypercholesterolaemia, but suffer from a poor safety record and low tolerance from common side effects (e.g. myalgia). As a results, the long term adherence to statins can be as low as 40% Alternatively, fermented red yeast rice (RYR) is a traditional Chinese food that been used as a relatively safe dietary supplement and herbal medicine for centuries and contains as its active ingredient, monocolin A which is identical in structure to one of the first generation of statins, lovastatin. RYR is has been reported to have the same efficacy in lower LDL-C as simvastatin and pravastatin. While this finding has not been reproduced for RYR at the high doses at which these statins are administered (20-50 mg/d), at 10 mg/d, RYR has been shown to lower LDL-C by more than of 15-20% in randomly controlled trials. Health claimsEFSA (ID 1648, 1700) health claims associated cholesterol management and heart health and specifically that monocolin K from RYR contributes to the management of normal blood cholesterol levels. Moreover, a cause and effect relationship has been established for an effect on LDL-C in the general population. SafetyThere have been numerous reports of adverse side effects to monocolin K at intakes as low as 5 mg/d, and safety warnings issued.
[0141] A review of monacolin K from red yeast rice (rice fermented with the red yeast Monascus purpureus) by the EFSA concluded that there was a relationship between the consumption of monacolin K from red yeast rice and maintenance of normal blood LDL-cholesterol concentrations (The EFSA Journal (2011), 9, (7), 2304).
[0142] The EFSA considered that in order to obtain to maintain normal blood LDL-cholesterol concentrations, 10 mg of monacolin K from fermented red yeast rice preparations should be consumed daily. Various red yeast rice preparations are available as food supplements. The preparations from red yeast rice typically contain starch, protein, fat (including monounsaturated fatty acids, plant sterols), isoflavones, and other compounds. Depending on the Monascus strains used and the fermentation conditions, the products may contain polyketides called monacolins, which are secondary metabolites produced during fermentation (Liu, J., et. al., (2006) Chinese Medicine, 1, 4).
[0143] Monacolin K, in lactone (also known as lovastatin or mevinolin) and hydroxy acid forms, is the main monacolin in Monascus purpureus-fermented rice (75-90% of total monacolin content) (Heber D., et. al., (2004) Am. J. Clin. Nutrition, 69, 231-236; and Li, Y. G., et. al., (2004) J. Pharm. Biomed. Analysis, 35, 1101-1112). Commercially available red yeast rice products have variable contents of monacolin K and total monacolins. A dose of 7.5 mg/day over a 12 week period has been shown to reduce LDL-cholesterol concentrations by 16% from baseline. Other studies which used a dose of 2.5 mg/day over a 8 week period also showed LDL-cholesterol concentrations reductions.
Soya Protein
[0144] Soya protein with or without soya isoflavones have been found to reduce cholesterol (Harland, J. I., et. al., (2012) Nutritional Research Reviews, 25, (2), 249-266). A daily intake of 25 g soya protein has been shown to provide an equivalent to 5.5% reduction in LDL-cholesterol. Substitution of 13-58 g soya protein containing foods per day for animal protein foods showed a 3.6-6.0% reduction in LDL-cholesterol. Currently, health claims in Europe and USA are allowed for the intake of 25 g soya to be associated with lowered blood cholesterol.
Dietary Fibres
[0145] There is strong and incontrovertible evidence for the beneficial effects of dietary fibre in reducing the risk of chronic degenerative diseases (cardiovascular disease, diabetes and certain cancers), and a critical need for populations at risk of these diseases to meet dietary recommendations for intake (e.g. UK 30 g/d from current national average intake of 12 g/d adults, NDNS 2014). Dietary fibre is non-digestible carbohydrates in whole grains, fruits vegetables and legumes that are classified by their water solubility, viscosity, fermentation and functional properties. The selection of fibres below is primarily based on the existing and emerging weight of evidence for their efficacy in reducing serum LDL-C, and existence of accepted health claims.
Soluble Fibre
-Glucans
[0146] -Glucan is a soluble, highly viscous and fermentable dietary fibre composed of linear chains of glucose, that is derived chiefly from oats and barley. While intakes of between 2-10 g/d have been consistently associated with reductions in serum LDL-C in meta-analyses, an intake of 3 g/d has been identified as a critical threshold for achieving a reduction in LDL-C of 0.3 mmol/l (10%), above which there is no further effect. The efficacy of the LDL-C lowering is greater in hypercholesterolaemic individuals, and in forms of -glucans with higher molecular weight and viscosity. There is some evidence to suggest that -glucans also lowers serum glucose and raises HDL-C. The mechanism of action of -glucans on LDL-C is primarily via the binding, excretion and thus further hepatic secretion, of bile acids. This interruption of the entero-hepatic circulation of bile acids depletes the hepatic pool of free cholesterol, which in turn up-regulates the gene expression and activity of LDL receptors. Health claimsEFSA Regular consumption of -glucans contributes to the maintenance of normal blood cholesterol concentrations (ID 1236, 1299); may increase satiety leading to a reduction in energy intake (ID 851, 852); may lower postprandial glycaemic response (ID 821, 824). Cause and effect relationships have been established for the former and latter claims. The U.S. Federal Regulations state that 3 g/d or more from either whole oats or barley or in combination can reduce risk of coronary heart disease. 3 g of soluble fibre from oats (3 servings of oatmeal, 28 g each) has also been found to decrease LDL-cholesterol by approximately 0.13 mmol/l (Brown L., et. al., (1999) Am. J. Clin. Nutr. 69, 30-42). Barley -glucans has also been shown to have cholesterol lowing properties. By reference to a sub-analysis it was established that 3 g barley -glucan was the minimum effective dose and, at this level of inclusion, LDL-cholesterol is reduced by 0.28 mmol/l, a reduction of approximately 7% compared with baseline, and total cholesterol by 0.34 mmol/l, a reduction of 5.7% (EFSA Report (2010) EFSA J, 8, 1885). In order to carry the health claim in Europe, foods must meet the condition that 3 g -glucans per day from oats, oat bran, barley, barley bran, or from mixtures of non-processed or minimally processed -glucans, should be contained in one or more servings. To achieve this level of -glucans intake, a typical serving of cereals required is about 84 g per day.
Pysllium
[0147] A soluble, viscous (gel-forming), non-fermented dietary fibre derived from the wheat husk of the seed of the Plantango plant, that is used as a bulk-forming laxative to treat constipation. Its metabolically active component is arabinoxylan. Intakes of 5-15 g/d have been reported to lower serum LDL-C by between 5-12%. It has also been reported to lower serum triglycerides, elevate HDL-C, and improve glycaemic control, especially in type 2 diabetes. Its mechanism of action may be through its gel-forming properties that increase the viscosity of chyme, reduce contact with digestive enzymes, thus delaying the absorption of nutrients. The delivery of increased amounts of carbohydrate to the ilieum may also elevate GLP-1, which is known to improve glycaemic control and reduce energy intake by reducing appetite and increasing satiety. Health claimsEFSA Inclusion of this fibre in a healthy diet and lifestyle may lead to a reduction in blood cholesterol (ID 4330). The U.S. federal regulations state that 7 g or more per day of fibre from psyllium seed husk can reduce the risk of CHD. Safetycan cause gas and stomach cramps and must be ingested with water to avoid swelling in the throat and choking.
Glucomannan
[0148] A water soluble, highly viscous type of fibre that does not occur naturally in food, but is extracted from the tubers of the Konjac plant, and is used as an emulsifying agent and thickener in foods. There is evidence to suggest that it may help to promote weight loss in overweight and obese individuals, and produce favourable effects on several biomarkers of cardio-metabolic health, including serum LDL-C. Much of the evidence for its beneficial effects are from animal studies (rat mainly). Data from randomly controlled trials in humans support a modest effect on weight loss, but there are no long term studies (>3 months). Its effects on biomarkers of risk are inconclusive. Health claimsEFSA Contributes to the reduction of body weight in the context of an energy-restricted diet (3 g/d); Helps to maintain physiological lipid levels (cholesterol and triglyceride) . . . and heart health. There is sufficient evidence for a cause and effect relationship between glucomannan and body weight, but not for the claims on blood lipids. The latter also applies to numerous other claims. Safetythere is no safety data in at risk groups. Glucomannan may interfere with normal glucose homeostasis and has physical side effects that include intestinal blockage.
Pectin
[0149] Viscous fibre in the form of pectins has also been recognised blood cholesterol lowering effects (Brown (1999)). Statistically significant effect of pectins on total and LDL-cholesterol at intakes of 2.2-9 g per day has been reported. There was also a significant dose-response relationship between the intake of soluble fibre (including pectins) and total and LDL-cholesterol lowering. It was estimated that 1 g pectins per day produced significant changes in total and LDL-cholesterol of 20.07 (95% Cl 20.117, 20.022) and 20.05 (95% Cl 20.087, 20.022) mmol/l, respectively (both P, 0.05). It has been suggested that in order to make a claim relating to the cholesterol effect, foods should provide at least 6 g of pectins per day in one or more servings (The EFSA Journal (2006) 8, 1747).
Chitosan
[0150] Another polysaccharide component for which an association between the maintenance of LDL-cholesterol and its consumption exists is chitosan (The EFSA Journal (2011) 9, 2214). The EFSA assessed evidence relating this polymer of -1-4-linked D-glucosamine and N-acetyl-D-glucosamine, which is a component of the exoskeleton of crustaceans and the cell walls of fungi. They suggested that the evidence indicated a small, but statistically significant effect on the reduction of both total (combining five studies) and LDL-cholesterol (combining two studies) concentrations, with no effect observed on HDL-cholesterol. The Panel suggested that in order to have an effect on blood lipids, 3 g chitosan per day should be consumed. The mechanism by which chitosan is presumed to exert the claimed effect is far from conclusive, but it was suggested that it binds to negatively charged lipids and reduces their gastrointestinal uptake.
Tree Nuts
[0151] In a systematic review of studies that examined the relationship between the intake of nuts and their effect on blood lipids, it was found that in three almond (intake 50-100 g per day), two groundnut (35-68 g per day), one pecan nut (72 g per day) and four walnut (40-84 g per day) studies that the decreases in total cholesterol were between 2 and 16% and those in LDL-cholesterol were between 2 and 19%, compared with subjects consuming control diets (Mukuddem-Petersen J., et. al., (2005) J Nutr 135, 2082-2089).
[0152] A further meta-analysis of five RCT (randomised control trials) (n 142) conducted specifically with almonds, where intake was 25-168 g per day, demonstrated a reduction in total cholesterol of 0.18 (95% Cl 20.34, 20.02) mmol/l (P, 0.05) and LDL-cholesterol of 0.15 (95% Cl 20.29, 0.00) mmol/l (NS). Studies conducted with walnuts were reviewed and random-effects meta-analysis of blood lipid outcomes was conducted in thirteen RCT (n 365). In these RCT, walnuts provided 10-24% of total energy intake. Diets supplemented with walnuts resulted in a significant reduction in total and LDL-cholesterol of 0.27 and 0.24 mmol/l, respectively (both P, 0.001).
[0153] In 2003 in the USA, a Qualified Health Claim was approved, which identified that the data suggested, that the intake of 1.5 oz (42 g) nuts per day may reduce the risk of heart disease.
Flavonoids
[0154] There has been some evidence recently that flavonoids, which are found in food products such as green tea and chocolate can lower cholesterol.
Garlic
[0155] There has been some evidence recently that garlic can lower cholesterol.
Prebiotics
Inulin
[0156] A 3-week study found that daily intake of 20 g of inulin significantly (P<0.05) reduced serum triglycerides in 8 healthy volunteers (23-32 years old, BMI of 19-25 kgm.sup.2). Similarly, a study involving eight healthy volunteers with a daily consumption of 10 g of inulin for three weeks also reached similar conclusions with a reduction of triglycerides in the region of 16.3% (Letexier, D., et. al., (2003) Am. J. Clin. Nutr. 2003, 77, 559-564). In animal studies, 10 male golden Syrian hamsters, mean BW of 584 g were given 16% of inulin daily for 5 weeks which resulted in TC: 29% decrease (P<0.05) and TG: 63% decrease (P<0.05) (Trautwein, E. A., et. al, (1998) J. Nutr. 128, 1937-1943).
[0157] Other indigestible and fermentable compounds such as germinated barley, oligodextrans, gluconic acid, lactose, glutamine, hemicellulose-rich substrates, resistant starch and its derivatives, lactoferrin derived peptide, and N-acetylchitooligosaccharides have also been identified to have prebiotic potential with hypocholesterolemic effects.
Fructooligosaccharides (FOS)
[0158] Twenty diabetic & hypercholesterolemic volunteers with fasting serum TC concentrations >6 mmol/L were given 15 g per day, two 20 days treatment periods, with no washout period between treatments. HDL-C was found to increase by 2.8% (Alles, M. S., et. al. (1999) Am. J. Clin. Nutr. 69, 64-69).
Galactooligosaccharides (GOS)
[0159] Forty four elderly volunteers (16 men & 28 women between 64-79 years old) were given 5.5 g per day of GOS, two 10 weeks treatment periods with a 4-week washout period (Vulevic, J., et. al., (2008) Am. J. Clin. Nutr. 88, 1438-1446). Whilst no significant improvements in lipid profiles were identified, it is believed that GOS may still confer a hypocholesterolemic effect at the right concentration.
Chitooligosaccharides (COS)
[0160] Forty Nine male Arbor Acres broiler chickens (196 days old) were given 100 mg/kg BW Daily for 42 days. This resulted in TG: 26.9% decrease (P<0.05) and HDL-C: 12.3% increase (P<0.05) (Li, X. J., et. al., (2007) Poultry Sci. 86, 1107-1114).
Xylooligosaccharides (XOS)
[0161] Forty male Sprague-Dawley rats (6 weeks old) were given a 60 g XOS/kg diet for 35 days. This resulted in TG: 33.9% decrease (P<0.05) (Hsu, C. K., et. al., (2004) J. Nutr. 134, 1523-1528).
Soybean Oligosaccharides
[0162] Fifty Wistar rats (4-weeks old) were hypercholesterolemic induced and given a diet of 450 mg/kg BW/day for 45 days. This resulted in TC: 38.5% decrease (P<0.05) LDL-C: 43.0% decrease (P<0.05) TG: 40.8% decrease (P<0.05) HDL-C: 81.9% increase (P<0.05) (compared to the positive control group) (Chen, H., et. al., (2010) Food Chem. 119, 1633-1636).
Fatty Acids
[0163] Alpha-linolenic acid (ALA)
[0164] A review of ALA by the EFSA concluded that there was a relationship between the dietary intake of ALA and the reduction of blood cholesterol concentrations (The EFSA Journal (2009), 7, (9), 1252). In order to bear a functional claims, a food should contain at least 15% of the proposed labelling reference intake value of 2 g ALA per day.
[0165] Indeed, clinical trials comparing the effects of different vegetable oils on serum lipids in normolipidaemic subjects have shown that the effect of alpha-linolenic acid (ALA) on serum cholesterol is similar to that of linoleic acid (LA)
[0166] A study looking at 3.4 g/day of ALA (by way of using flax oil and rice oil in bread rolls), resulted in systolic BP being significantly lower (about 4 mmHg) after 4, 8 and 12 weeks (Takeuchi H., et. al., (2007) J. Oleo. Sci. 56, 347-360). A 12-week study compared the effect of daily supplementation with flaxseed oil (15 ml providing 8 g ALA and 2 g LA, n=59) with safflower oil (15 ml providing 0.1 g ALA and 11 g LA, n=28) on BP in middle-aged dyslipidaemic men. Background diets of the two groups had similar quantities of ALA (1 g/d) and total PUFA (12 g/d). After 12 weeks, a median decrease of 3% in systolic BP and of 6% in diastolic BP was observed (median decrease around 5 mm Hg) in the intervention group compared to controls (Paschos G. K., et. al., (2007) Eur. J. Clin. Nutr. 61, 1201-1206).
[0167] ALA can be found in approximately 2-3 g flaxseed and can be provided either whole or as its lignin component.
Long Chain n-3 Polyunsaturated Fatty Acids (PUFA)
[0168] Dietary long chain n-3 PUFA, eicosapentaenoic and docosahexaenoic acids (EPA, DHA or omega-3s), derived chiefly from oily fish, are associated with reduced CVD risk and the prevention of sudden cardiac death, in part, through their anti-arrhythmic effects and ability to stabilise atherosclerotic plaque. These fatty acids also exert favourable physiological effects on cardio-metabolic risk factors, such as improving vascular dysfunction, lowering blood pressure, modulating inflammatory and immune function and reducing serum triglyceride in the post-prandial and post-absorptive (fasted) states. The latter improves lipoprotein profile, chiefly by increasing the capacity to hydrolyse TG-rich lipoproteins and lower the serum concentration of atherogenic lipoprotein remnants, and by doing so, reducing the propensity to deposit visceral fat, and ectopic fat in the liver. One potentially adverse effect of EPA/DHA is to increase serum LDL-C by between 5-10%. However, while raised serum LDL-C can co-exist alongside cardio-metabolic risk factors in insulin resistant conditions of obesity, metabolic syndrome and type-2 diabetes (cholesterol biosynthesis in the body increases with weight gain), it is not strictly a cardio-metabolic risk factor. Cardio-metabolic risk is characterised by a predominance of small, dense LDL (sdLDL) which are relatively depleted of cholesterol, and express a reduced affinity for the LDL receptor and increased atherogenic potential. One favourable effect of the hypo-triglyceridaemic action of EPA/DHA is to remodel sdLDL into large LDL particles. This results in a small increase serum LDL-C, but at the same time renders LDL more receptor active and less atherogenic.
[0169] In practice, this effect can be exploited by combining EPA/DHA with an LDL-C lowering agent that works by up-regulating LDL receptor activity, either directly (e.g. statin) or indirectly by reducing cholesterol absorption in the gut (e.g. sterol/stanol or a pro-biotic). These complementary mechanisms of action help to explain why the addition of fish-oil increases the efficacy of statins in lowering serum LDL-C.
[0170] High-fish diets (1.23 g/day eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)) are known to decrease non-fasting plasma triglycerides, with concomitant reductions in triglyceride-rich lipoprotein (TRL) apoB-100 concentration and production rate, compared with a low-fish diet in elderly men and women with moderate hyperlipidemia (Ooi, E. M., et. al., (2012) J. Lipid Res. 53, 1958-1967). The study was a 12-week, randomized intervention trial of a hypocaloric diet (energy deficit of 1900 kJ) and n-3 PUFA supplement (4 g/day Omacor; 46% EPA and 38% DHA) compared with a hypocaloric diet alone on TRL apoB-48 metabolism in obese men and women following ingestion of an oral fat load (a total of 4800 kJ, 130 g fat, 17 g protein, and 21 g carbohydrate). Studies have shown that weight loss and n-3 PUFA supplement decreased fasting and total postprandial TRL apoB-48 area under the curve (AUC) compared with weight loss alone.
Omega-6 Polyunsaturated Fatty Acids (n6-PUFAs)
[0171] A recent study by van Schalkwijk et al. examined the effect of 60 g per day of dietary n-6 PUFA (71% linoleic acid) compared with medium-chain fatty acid (MCFA; 69% C8:0 and 010:0) supplementation on fasting lipoprotein profile and metabolism in 12 overweight-obese men using a randomized, double-blind crossover study design (Van Schalkwijk, D. B., et al., (2014) PLoS ONE, 9, e100376). Three weeks supplementation with n-6 PUFA lowered fasting total, very low-density lipoprotein (VLDL) and LDL cholesterol, and total plasma, VLDL and LDL triglyceride concentrations compared with MCFA.
