Welcome to Day 2 of the Brain Health Challenge. Today, we’re talking about food.
Your brain is an energy hog. Despite comprising about 2 percent of the average person’s body mass, it consumes roughly 20 percent of the body’s energy. In other words, what you use to fuel yourself matters for brain health.
So what foods are best for your brain?
In a nine-year study of nearly 1,000 older adults, researchers at Rush University in Chicago found that people who ate more of nine particular types of food — berries, leafy greens, other vegetables, whole grains, beans, nuts, fish, poultry and olive oil — and who ate less red meat, butter and margarine, cheese, sweet treats and fried food had slower cognitive decline.
Based on these findings, the researchers developed the MIND diet.
Large studies encompassing thousands of people have since shown that following the MIND diet corresponds with better cognitive functioning, a lower risk of dementia and slower disease progression in people with Alzheimer’s. People benefit from the diet regardless of whether they start it in midlife or late life.
Experts think the foods included in the MIND diet are especially good for the brain because they contain certain macro and micronutrients.
Berries and leafy greens, for example, are rich in polyphenols and other antioxidants, said Jennifer Ventrelle, a dietitian at Rush and a co-author of “The Official Mind Diet.” Many of these compounds can cross the blood-brain barrier and help to fight inflammation and oxidative stress, both of which can damage cells and are linked to dementia.
Nuts and fatty fishes, like salmon and sardines, contain omega-3 fatty acids, which are important for building the insulating sheaths that surround the nerve fibers that carry information from one brain cell to another.
Whole grains and beans both contain a hefty dose of fiber, which feeds the good microbes in the gut. Those microbes produce byproducts called short-chain fatty acids that experts think can influence brain health via the gut-brain axis.
You don’t have to revamp your whole diet to get these nutrients. Instead, think about “MIND-ifying” whatever you already tend to eat, said Dr. Joel Salinas, a neurologist at NYU Langone Health and the founder and chief medical officer of the telehealth platform Isaac Health. For instance, add a handful of nuts or berries to your breakfast.
Today’s activity will help you MIND-ify your own meals. Share your choices with your accountability partner and in the comments, and I’ll discuss the ways I’m adjusting my diet, too. For added inspiration, check out these MIND-approved recipes from New York Times Cooking.
