Like most people over 40, I\u2019ve noticed that my memory can sometimes be a little sluggish, and my mind doesn\u2019t always seem to be as quick and sharp as it was when I was, say, in my 20s. This cerebral slowdown is even more likely to be true for those of us who have other medical issues, particularly conditions like long COVID<\/a> or menopause<\/a> that can be notorious for causing \u201cbrain fog.\u201d<\/p>\n

I\u2019ve mostly chalked this up to an inevitable part of getting older. But I never really stopped to consider that what I\u2019m putting in my fridge or on my dinner plate might be partly to blame. <\/p>\n

Here\u2019s how your brain changes as you age. <\/strong><\/p>\n

Our brains, like many other parts of our bodies, undergo significant changes as we age. \u201cAs we age, our brain naturally goes through changes,\u201d said Dr. Alexander Zubkov<\/a>, a board-certified neurologist and part of the Scientific Advisory Board of 1MD Nutrition. \u201cBlood flow to the brain tends to slow down, and there\u2019s often a gradual decline in neurotransmitter levels, especially those related to memory, mood, and focus \u2014 like dopamine, acetylcholine and serotonin.\u201d<\/p>\n

Zubkov says oxidative stress<\/a> and chronic low-grade inflammation<\/a>, both of which are known contributors to cognitive decline, also build up over time.<\/p>\n

On the upside, age can also bring some positive changes to our cognitive abilities. \u201cAs we get older, learning and memory tend to become more difficult,\u201d said Yuko Hara, the director of aging and Alzheimer\u2019s prevention at the Alzheimer\u2019s Drug Discovery Foundation<\/a> (ADDF). \u201cHowever, not everything goes downhill with aging. Vocabulary increases with age, and so does wisdom. Crystallized intelligence (the total knowledge gained over time) increases with age, allowing older people to reflect on and examine situations more effectively and to make informed decisions.\u201d <\/p>\n

What you eat can have a big impact on your brain. <\/strong><\/p>\n

Our diet affects virtually every part of our body, including our brain. \u201cA healthy diet is important for brain function and cognitive health,\u201d Hara said. She says you can maximize the positive ways a healthy diet influences brain health by incorporating foods with antioxidant<\/a> and anti-inflammatory<\/a> properties into your diet. <\/p>\n

Zubkov says a nutrient-dense diet \u201cprovides the building blocks for neurotransmitters, supports cellular repair, reduces inflammation, and protects against oxidative damage.\u201d <\/p>\n

Foods can be good for your brain:<\/strong><\/p>\n

Experts have recommendations for foods you might want to include on your grocery list to help support your brain health. Registered dietitian nutritionist (RDN) Lauren Manaker <\/a>cites these foods that are known for their brain-boosting benefits: <\/p>\n

True tea<\/strong><\/p>\n

True tea \u2014 which, unlike herbal tea, is derived from the Camellia sinensis<\/a> plant \u2014 includes varieties such as green tea, black tea, white tea and oolong tea. Manaker says this kind of tea is a natural source of antioxidants like catechins and flavonoids, which help protect brain cells from oxidative stress and inflammation. In addition, she notes, true tea contains L-theanine \u2014 an amino acid that helps you relax without feeling drowsy \u2014 and caffeine, which enhances alertness and cognitive performance. \u201cTogether, these elements may support focus, memory, and overall mental clarity.\u201d Studies have shown<\/a> that frequent tea consumption, particularly drinking green tea, can have a positive cognitive effect on older people. <\/p>\n

Walnuts <\/strong><\/p>\n

Manaker says it\u2019s fitting that walnuts look somewhat like tiny brains \u2014 take it as a hint from Mother Nature that this tree nut is good for our brain. \u201cWalnuts are often hailed as a superfood for brain health due to the nutrients they naturally contain, including antioxidants and magnesium,\u201d Manaker said. <\/p>\n

Walnuts are the only tree nut that is an excellent source of ALA omega-3 fatty acids<\/a>, Manaker said, adding that data shows<\/a> that higher levels of ALA in the blood were linked to better energy usage in brain regions typically affected in Alzheimer\u2019s Disease (AD). These links were even stronger in individuals carrying certain genetic markers for AD risk.<\/p>\n

Mushrooms <\/strong><\/p>\n

Mushrooms are increasingly recognized as a superfood for brain health, Manaker said, thanks to their rich nutritional profile and unique compounds. This includes ergothioneine<\/a>, a powerful antioxidant and anti-inflammatory agent. \u201cErgothioneine helps protect brain cells from oxidative stress and inflammation, both of which are linked to cognitive decline and neurodegenerative diseases,\u201d Manaker said. \u201cAdditionally, mushrooms contain essential nutrients like B vitamins and amino acids, which support overall brain function and energy metabolism.\u201d<\/p>\n

Other foods that Zubkov recommends for supporting brain health include fatty fish like salmon and sardines, which are rich in omega-3 DHA, considered essential for brain cell structure; blueberries, because they\u2019re packed with anthocyanins, which fight oxidative stress and improve memory; and leafy greens like spinach and kale, which are high in folate, vitamin K, and lutein, all linked to slower cognitive decline. <\/p>\n

There are other foods you may want to avoid. <\/strong><\/p>\n

Some foods, on the other hand, may not be so beneficial for your brain health \u2014 and may not be great for your health overall \u2014 so you may want to limit their role in your daily diet. Dr. Joshua Helman<\/a>, a Harvard-trained physician specializing in reversing and preventing cognitive decline, easily identifies one category of foods of concern. \u201cHighly processed foods, especially those high in added sugars, refined grains, trans fats, and omega-6\u2013heavy oils, promote inflammation and insulin resistance in the brain.\u201d Helman notes this connection between unhealthy processed foods and cognitive health has led some researchers to refer to Alzheimer\u2019s as \u201ctype 3 diabetes.\u201d<\/p>\n

\u201cI also advise people to be cautious with foods high in sodium, nitrates or artificial additives,\u201d Helman said. \u201cThese can contribute to vascular damage, which is a major driver of cognitive impairment. Many people are surprised to learn that even moderate exposure to pesticides, plastics, and heavy metals in food and water can interfere with memory and focus over time.\u201d <\/p>\n
