Beans Brain Health | Brain Foods After Stroke

Beans Brain Health.

How do I know? AI told me so. Then I decided to find out if it was right.

I knew about cocoa and coffee, walnuts, olive oil, and berries (and fruits). But beans? Not so much.

So with this blog, I decided to figure out why beans are brain foods — what I knew about them in the old days (up until about a month ago) and what I am discovering now.

Why beans are brain foods

Before I talk about my own bean history, here is why beans are considered brain foods.

Beans are full of fiber, plant protein, and important nutrients like folate, magnesium, and iron. These nutrients help support healthy blood flow and steady blood sugar, which are both important for the brain.

Beans also support the gut microbiome — the healthy bacteria in our digestive system. Scientists are learning that the gut and the brain communicate with each other, sometimes called the gut–brain connection.

And one more thing: beans are a key food in healthy eating patterns like the Mediterranean diet and the MIND diet, which are both associated with better brain health and lower risk of cognitive decline.

So beans may not look glamorous, but they quietly do a lot of good work for the brain.

What I knew about beans

Back in the 1950s and 60s, beans were only an occasional food in my house.

I ate chili (I still do). People talked about using kidney beans in chili — which I hated. Instead, I used black beans with either ground beef or turkey. I liked it. It is one of the few things I cook without reading a recipe. I just sort of know how to make it.

The only other bean I remember eating was Boston baked beans — out of a can. We ate them once in a while.

That’s it.

The sum total of my bean experience for 73 years.

I admit something else. I bought cans of beans that sat in the cabinet for years. I am being honest here.

Keith’s bean experience was different but still limited. As a kid he ate one kind of bean: black-eyed peas. His mother grew up in the South and loved them. Keith thought they tasted like sand.

In the 2000’s we added hummus — the popular Middle Eastern spread made with chickpeas that is now in every grocery store in the United States.

What changed

Since starting my Brain Foods series, I decided to try beans once a week.

I started reading ideas from The New York Times cooking section. And guess what? I’ve loved it — and so have my husband Keith and my nephew, Catt. All of us liked the recipes.

Here are five reasons I suddenly like beans. Interestingly, none of them have anything to do with the brain.

I like the variety.
I like black beans, cannelloni (white) beans, lentils (especially red ones), and chickpeas. I can use them in many different recipes.

Beans are global food.
Beans are popular all over the world. The New York Times recipes introduce me to international cooking ideas that are fun and really good.

Beans are inexpensive.
This matters in 2026. Groceries are getting expensive. Beans are a good way to cook healthy meals without spending a lot of money.

Beans work in every season.
Winter foods: chili, soups, and stews.
Summer foods: salads, grain bowls, and lighter dishes.

I still have experiments ahead.
People say dried beans are even better than canned beans. I don’t know about that yet. It is on my list of experiments. Usually it means soaking the beans the night before cooking. I will try it sometime.

Recipes I tried this month

Here are four recipes I made recently from the New York Times cooking section:

Ham and Bean Soup with Collard Greens

Vegetable Tortilla Soup

Creamy Spicy Tomato Beans and Greens

Rice and Beans with Extras

All of them were delicious.

So try beans

You and your family might like them.

And you will be making your brain happy — and your wallet a little more relaxed.

A note about the Brain Foods series

This is the fifth of my Brain Foods After Stroke blogs.

When I started, I thought the list would be seven foods. But now it may become eight.

I am also looking at ultra-processed foods — and why reducing them may help brain health. Researchers at the National Institutes of Health and Harvard have written about this.

More on that later.
