Description

DESCRIPTION OF EMBODIMENTS

[0015] The present invention will be described in more details.

[0016] A health drink of the present invention contains a water-soluble nucleoprotein as an active component.

[0017] The water-soluble nucleoprotein that can be used in the health drink of the present invention is not particularly limited as long as it is a water-soluble nucleoprotein obtained by extracting nucleic acid from a biological cell and enzymatically treating thereof so as to reduce a molecular weight thereof. Examples for the water-soluble nucleoprotein include a water-soluble nucleoprotein obtained by subjecting milt of fish to enzymatic treatment so as to reduce a molecular weight and to make water-soluble.

[0018] The term “water-soluble” as used herein means a property capable of being dissolved in water at a concentration of 0.1% by mass or more.

[0019] Examples for the fish milt include milt of salmon, trout, herring, and the like. The salmon milt is preferable.

[0020] Examples for the enzymatic treatment of fish milt include a method of crushing milt of fish to obtain a suspension, and then treating the obtained suspension with protease, and then with nuclease.

[0021] Usually, DNA extracted from milt has a molecular weight of 1 million or more, but the molecular weight is reduced by enzymatic treatment. A preferable water-soluble nucleoprotein includes preferably 20% by mass or more, and more preferably 30% by mass or more of nucleoside/nucleotide/oligonucleotide/polynucleotide having a molecular weight of 250 to 100000, preferably 500 to 13200, or 250 to 6600.

[0022] Further preferably, a water-soluble nucleoprotein includes 2% by mass or more of nucleoside/nucleotide/oligonucleotide/polynucleotide having a molecular weight of 500 to 13200, and 18% by mass or more of the above having a molecular weight of 250 to 6600.

[0023] The health drink of the present invention includes 3 g to 20 g, preferably 3 g to 15 g, more preferably 4 g to 10 g, and further preferably 4 g to 7 g of a water-soluble nucleoprotein, for example, as a DNA-containing salmon milt extract, per 720 mL of the health drink.

[0024] The health drink of the present invention can also include RNA as a component other than the water-soluble nucleoprotein.

[0025] The above-mentioned RNA is not particularly limited as long as it is low-molecular weight RNA obtained by reducing the molecular weight of ribonucleic acid (RNA). Specifically, suitable examples include RNA obtained by extracting and purifying RNA from well-known yeast such as beer yeast, torula yeast, milk yeast, and baker's yeast, and reducing the molecular weight of the RNA, so that the RNA contains 20 to 50% of a fraction having a molecular weight of 1000 to 33000, and a fraction having a molecular weight of 1000 or less in a larger rate that is more than that of the molecular weight of 1000 to 33000, for example, a rate of 30 to 50%.

[0026] Examples of the method for producing and obtaining the above RNA include well-known methods such as a method of subjecting the RNA isolated, extracted, and purified from the above yeast to enzyme decomposition treatment or hydrolysis treatment so as to reduce the molecular weight thereof; a method of chemically or enzymatically synthesizing the RNA; and a method of purchasing a commercial product of RNA.

Examples for the collagen derivative include atelo products, acylated products, succinylated products, and the like, of collagen and hydrolyzate thereof. It is common to use a water-soluble collagen hydrolyzate (collagen peptide) because the typical collagen has a molecular weight of about several tens of thousands to 300000 and is usually water-insoluble.

Specifically, examples for the preferable combination of vitamins include all of vitamin C, vitamin B1, vitamin B2, vitamin B6, vitamin B12, folic acid, niacin, and calcium pantothenate.

[0049] When the health drink of the present invention includes eight kinds of vitamins as mentioned above, the addition amount of vitamin C is in the range of 1500 mg to 7000 mg, preferably 2000 mg to 7000 mg, and more preferably 3000 mg to 6000 mg per 720 mL of the health drink; the addition amount of vitamin B1 is in the range of 5 mg to 50 mg, preferably 10 mg to 40 mg, and more preferably 10 mg to 30 mg per 720 mL of the health drink; the addition amount of vitamin B2 is in the range of 5 mg to 50 mg, preferably 10 mg to 50 mg, and more preferably 14 mg to 40 mg per 720 mL of the health drink; the addition amount of vitamin B6 is in the range of 5 mg to 50 mg, preferably 10 mg to 50 mg, and more preferably 15 mg to 45 mg per 720 mL of the health drink; the addition amount of vitamin B12 is in the range of 10 mg to 70 mg, preferably 20 mg to 70 mg, and more preferably 25 mg to 65 mg per 720 mL of the health drink; the addition amount of folic acid is in the range of 1 to 8 mg, preferably 1 to 7 mg, and more preferably 2.5 to 6.5 mg per 720 mL of the health drink; the addition amount of niacin is in the range of 50 mg to 500 mg, preferably 100 mg to 400 mg, and more preferably 120 mg to 350 mg per 720 mL of the health drink; the addition amount of calcium pantothenate is in the range of 30 mg to 300 mg, preferably 50 mg to 250 mg, and more preferably 50 mg to 200 mg per 720 mL of the health drink.

[0050] The health drink of the present invention can also include other components other than the components mentioned above as a water-soluble nucleoprotein.

[0051] The above other components include sweeteners such as fructose glucose liquid sugar, refined white sugar, syrup containing rare sugar, erythritol, and sucralose, fruit juices such as pineapple juice, preservatives such as sodium benzoate, colorants such as caramel pigments, emulsifiers (for example, derived from soybean), perfumes, acidifiers, and the like. When the health drink of the present invention contains these other components, an appropriate amount of each component can be added.

[0052] The health drink of the present invention has action mechanisms useful for health, such as an elevation of a score of the CD4/CD8 cell ratio, an elevation of a score of the naive/memory T cell ratio, an elevation of a score of the number of NK cells, a decrease in a concentration of 8-OHdG, enlargement of a particle diameter of LDL in a small dense LDL fraction, an elevation of a concentration of HDL-C, and an elevation of a concentration of hemoglobin, and an increase in a rate of hematocrit.

[0053] In the above action mechanisms, all of the elevation of the score of the CD4/CD8 cell ratio, the elevation of the score of the naive/memory T cell ratio, and the elevation of a score of the number NK cells are thought to contribute to improvement in immune function.

[0054] The 8-OHdG is an indicator that reflects the degree of oxidative damage to DNA in living organisms. Therefore, a decrease in the concentration of 8-OHdG is thought to reduce the degree of oxidative genetic damage.

[0055] Furthermore, enlargement of a particle diameter of LDL in a small dense LDL fraction is thought to contribute to health for the following reasons.

[0056] As compared with ordinary large LDL, the small particle LDL is not easily metabolized in the liver and resides in blood for longer time because the small particle LDL has less affinity to an LDL receptor; small LDL particles are easily bonded to polysaccharide; small LDL particles easily enter the vessel wall because they are small particles; small LDL particles are susceptible to oxidative denaturation due to little antioxidants against oxidative stress, are called “super bad cholesterol”, and are a risk factor for atherosclerosis.

[0057] Therefore, the enlargement of the particle diameter of LDL in a small dense LDL fraction is thought to reduce the risk of occurrence of atherosclerosis. Furthermore, since there is a description that the particle diameter of LDL becomes smaller mainly when the value of triglyceride (TG) is high, it is suggested that the enlargement of the particle diameter in a small particle LDL may activate lipid metabolism.

[0058] HDL-C is responsible for eliminating excess cholesterol and is also called good cholesterol. Therefore, it is thought that the elevation of the concentration of HDL-C reduces the risk of occurrence of arteriosclerosis.

[0059] Hemoglobin and hematocrit are indicators of anemia, and the like. Therefore, an elevation of the concentration of hemoglobin and an increase in the rate of hematocrit may contribute to improvement of anemia.
