7) Digestion
Vinegar may modulate acid/alkaline balance and promote the growth of healthy bacteria in the stomach. In animals, the ingestion of vinegar increased the quantity of minerals and vitamins absorbed from food, possibly because several vitamins and minerals are better absorbed at lower pH (higher acidity) [You do not have permission to view the full content of this post.

8) Cognitive Decline
Kurozu, a traditional rice wine vinegar, shows a tendency to suppress cognitive dysfunction and amyloid accumulation in mice. This particular study found that vinegar might help the production of proteins likeYou do not have permission to view the full content of this post.
