People ask me all the time what they should eat to help keep their brain sharp. As a dietitian, it\u2019s one of my favorite questions to answer because the answer often surprises them: One of the best brain-supporting foods you can eat is probably already sitting in your kitchen!<\/p>\n
Mushrooms<\/a>.<\/p>\n The same earthy fungi you toss into pasta or layer onto pizza turn out to be one of the most interesting foods for brain health, and the science behind them keeps getting stronger. They\u2019re also not alone. A handful of other everyday staples round out the list, and the best part is you probably already have most of them on hand. Keep reading for what to put on your plate, and why it matters.<\/p>\n HUIZENG HU\/\/Getty Images<\/p>\n Why Mushrooms Are Good For Brain Health<\/p>\n Mushrooms owe a lot of their brain-supporting potential to a compound called ergothioneine, or ERGO for short. It\u2019s a potent antioxidant that your body can\u2019t produce on its own, and mushrooms happen to be one of the best food sources.<\/p>\n Researchers have been paying close attention to ERGO because of how it may relate to brain aging. In one study<\/a> of nearly 500 older adults attending memory clinics, those with lower blood levels of ergothioneine experienced faster decline in memory, language, and daily function over several years. The study was observational, so this does not mean ERGO is a cure for anything, but it does suggest the compound may be worth watching as a marker of brain health.<\/p>\n But there’s more. In a study of 663 older adults<\/a>, higher mushroom consumption was associated with a lower likelihood of having mild cognitive impairment, even after researchers accounted for lifestyle and demographic factors. Again, this shows a link rather than proof of cause and effect, but it adds to a growing pile of evidence pointing in a promising direction.<\/p>\n Why does this matter for your grocery list? Because some researchers suggest the typical American diet may run low in ERGO, and we can\u2019t make it ourselves. We have to get it from food. That\u2019s a pretty compelling reason to keep mushrooms in regular rotation.<\/p>\n And mushrooms are ridiculously easy to eat more of. Saut\u00e9 them in olive oil with garlic. Fold them into scrambled eggs<\/a>. Roast a tray of oyster mushrooms until crispy. Blend finely chopped shiitakes into ground meat for burgers or tacos. They\u2019re savory, satisfying, and they stretch a meal without much effort.<\/p>\n Penpak S.\/\/Getty Images<\/p>\n Other Best Foods For Brain Health<\/p>\n No single food carries your brain on its own. Brain health comes from an overall pattern of eating, day after day. So while mushrooms deserve the spotlight, a few other everyday staples deserve a spot on your plate.<\/p>\n Eggs<\/strong><\/p>\n Eggs are one of the most convenient brain-friendly foods out there, and they\u2019re likely already in your fridge. They\u2019re the top food source of choline, a nutrient your brain uses to make acetylcholine, a chemical messenger involved in memory and learning.<\/p>\n The research here is worth knowing. In a study <\/a>of more than 1,000 older adults, consuming at least one egg per week was associated with a roughly 47 percent lower risk of Alzheimer’s dementia, and about 39 percent of that association appeared to be linked to dietary choline.<\/p>\n Add Delish as a preferred source in your Google search results.<\/p>\n Use your Google account to add this to your settings.<\/p>\n Add to Google settings<\/p>\n Scramble them, hard-boil a batch<\/a> for the week, or fold them into that mushroom saut\u00e9 I mentioned earlier.<\/p>\n Walnuts<\/strong><\/p>\n Walnuts<\/a> are worth keeping in your kitchen for more than just snacking. They\u2019re a source of polyphenols that support brain health in a pretty cool way: Your gut bacteria convert them into compounds called urolithins, which have antioxidant and anti-inflammatory properties that researchers believe may benefit the brain over time.<\/p>\n In one two-year study<\/a>, older adults who ate walnuts regularly showed meaningful improvements in cognitive performance, and those urolithins were proposed to be part of the reason why. So it\u2019s not just about eating a handful of nuts and hoping for the best. There\u2019s a real biological pathway here, and it goes straight through your gut.<\/p>\n The research is still growing, but it\u2019s a genuinely good reason to keep a bag on hand. Just put them in your fridge after you open the bag. Their natural oils stay fresher longer that way.<\/p>\n![\"Fresh](\"https:\/\/www.europesays.com\/ie\/wp-content\/uploads\/2026\/08\/bce659a1-9921-47b4-b44c-c59a6f4bf158.jpeg\" "\\"Fresh")
