The 8 worst foods for your brain

There is a sweet spot for alcohol consumption, according to neurologist Dr David Perlmutter and author of Grain Brain: The Surprising Truth about Wheat, Carbs, and Sugar. While the occasional glass of red wine is okay, drinking in excess can be toxic to your brain function, no matter your age. Research, including a study published in 2017 in the peer-reviewed medical trade journal BMJ, found that moderate drinking can damage the brain. The hippocampus is particularly vulnerable.

To protect your brain, limit alcohol consumption to no more than one standard drink per day for women and two per day for men. According to Australia’s national alcohol guidelines, one standard drink is defined as containing 10 grams of alcohol.
