Another benefit of grapes, relevant sections from article:

Chances are that you already like the taste of grapes. If you're looking for another reason to eat them, though, then how about this … a recent study conducted by the University of California, Los Angeles indicates that consuming them helps protect against Alzheimer's disease.

It was discovered that while the placebo group exhibited significant metabolic decline in regions of the brain that are affected by the early stages of Alzheimer's, the grape powder group maintained a healthy level of metabolic activity in those areas. What's more, the grape group also "showed beneficial changes in regional brain metabolism that correlated to improvements in cognition and working memory performance."

This effect is likely due to the known antioxidant and anti-inflammatory properties of the polyphenols. It is believed that they reduce oxidative stress in the brain, while also promoting blood flow within it and maintaining levels of a chemical that boosts memory.

Therefore, here we see more evidence that dietary choices can have profound impacts on human health and the course of even some of the most serious diseases.
