A flavor composition comprising at least one compound that modulates, increases and/or enhances the activity of a GPR120 fatty acid receptor that can be used to enhance the fatty acid taste and/or palatability of pet food products is described herein. Also disclosed herein are methods for identifying said compounds.

Provided herein are compositions (e.g., pharmaceutical compositions, nutraceutical compositions, foods, beverages, cosmetic compositions, diet supplements) comprising deuterated caffeine. The provided compositions may be useful for treating and/or preventing various diseases and conditions, such as obesity, causing weight loss, increasing metabolic rate, reducing appetite, increasing energy expenditure, increasing urine output, increasing sodium excretion, reducing edema, a pain disorder, apnea, hypotension, an encephalopathy, a neurological or psychiatric disorder, and an inflammatory disorder.
