Acetic acid is the component that gives vinegar its typical sour taste.

Function

  According to Ostman (1995), acetic acid regulates both glycaemia and insulinemia; according to Nakao (2001), it may facilitate the restoration of glycogen stores in the liver. Now, since hepatic glycogen is the source of sugars from which the brain draws when needed, acetic acid, by helping to replenish that, indirectly aids central recovery from training fatigue. This is particularly true if no sugars are consumed during load application.

Negative notes

  No adverse effects due to acetic acid intake have been reported.

Form and posology

  Food vinegar is a good source of this substance. There are no indications as to the quantity to be consumed. I simply suggest using vinegar as a condiment in the context of the observed diet. (Vinegar, however, independently of the function performed by acetic acid, contributes to the onset of satiety. It can therefore be a small aid in the context of low-calorie diets).
