Acetic Acid Feeding Enhances Glycogen Repletion in Liver and Skeletal Muscle

Acetic Acid Feeding Enhances Glycogen Repletion in Liver and Skeletal Muscle of Rats -- Fushimi et al. 131 (7): 1973 -- Journal of Nutrition:

"Our results show that dietary acetic acid can enhance glycogen repletion in both liver and skeletal muscle. The mechanism of this effect is different in liver and skeletal muscle. In liver, acetic acid feeding enhances glycogen repletion by activation of gluconeogenesis and the preferential utilization of G-6-P for glycogenesis. In skeletal muscle, the enhancement of glycogen repletion by acetic acid feeding results from the accumulation of G-6-P due to suppression of glycolysis. We used acetic acid at concentrations comparable to those found in a normal diet. Therefore, we conclude that supplementing meals with vinegar may be beneficial in the recovery of liver and skeletal muscle glycogen, for example, upon fatigue, after skipping meals, postexercise or as part of an athlete’s breakfast on the day of competition."
