flavonoids in the diet prevent Alzheimer's disease

Imagine if making simple changes to your diet—changes that taste good and are good for you anyway—could go a long way toward preventing Alzheimer’s. That would, literally, be food for thought!

A massive study followed 2801 people for an average of 19.7 years to see what impact flavonoids in their diet would make on the risk of Alzheimer’s.

Flavonoids are a big reason for the health promoting properties of many of the most powerfully healthy foods and herbs. They are anti-inflammatory, antioxidant, antiviral and anticancer. Turns out, they are also anti-Alzheimer’s. This study found that the people who got the most flavonoids in their diet over twenty years were significantly less likely to develop Alzheimer’s or Alzheimer’s related dementias.

When they broke down the classes of flavonoids, they found that the risk of Alzheimer’s and Alzheimer’s related dementias went down by 46% for flavonols, 76% for anthocyanins and 42% for flavonoid polymers. Specifically for Alzheimer’s, the benefits were essentially the same except that for flavonoid polymers the benefit, though large, was no longer statistically significant.

This study reinforces the importance of diet for cognitive health as we age. It also shows the potential importance of long-term flavonoid intake for preventing Alzheimer’s. So, eat drink your green tea, eat your dark chocolate, enjoy your soy and load up on fruits and berries.
