The Hidden Power on Your Plate

Most people want to stay mentally sharp as they age, yet few think about brain health when making daily food choices.

While a well-rounded healthy diet is required to promote brain function, an AARP study found only 1% of individuals consume the recommended number of servings in all five food groups. This can be especially problematic for older adults. Though good nutrition is needed over a lifetime, each phase of life requires emphasis on different elements. The Gerontological Society of America acknowledges that older adults are at risk of decreased absorption of certain nutrients so maintaining a healthy diet is key to overcoming lack of absorption to preserve – and optimize – brain health as you age.

Without recognizing how food choices directly shape memory, focus, and cognitive resilience, however, many adults do focus on “healthy eating” in a general sense—fruits, vegetables, balance. In AARP’s 2025 Nutrition and Brain Health study, people readily acknowledge that nutrition affects their overall health, but only a handful say they choose foods specifically to support their brains. In short: the connection is clear, but it’s not top of mind.

“ ”

I don’t have any knowledge about foods that impact ‘brain health’ any more than just overall health. Nor am I aware of scientific consensus on this point.

–Ages 40–54

“ ”

If I keep my body in good working order through healthy nutrition (and physical exercise, too, of course), then my brain will also benefit from the same nutritional inputs.

–Age 55+

“ ”

I think fresh fruits and vegetables are specific contributors to brain health … I don't recall where I specifically learned about the brain health benefits but I do read a lot on health.

–Age 55+

So, what does a brain-healthy diet look like?

The GCBH outlines five recommendations for maintaining brain health through diet. These include eating foods such as berries, fresh vegetables, fish, and grains, limiting the consumption of processed foods and red meats, drinking plenty of water, and avoiding or moderating alcohol consumption, and avoiding trans fats. AARP’s research finds that two in three adults age 40-plus take part in these healthy eating behaviors at least occasionally in a typical week.

Knowing Isn’t the Same as Doing

Here’s the surprising part: inaction isn’t caused by lack of knowledge.

Half of adults age 40-plus believe they already understand what a healthy diet looks like — yet only one in five say it’s easy to maintain one, and fewer than one third report eating healthfully most of the time.

Even more striking:

• Only 1% of adults in a major AARP study met the recommended servings across all five food groups,
• One in three regularly eats foods discouraged by the GCBH, including heavily processed and high sugar foods common in the Western diet,
• And, when ranked among other lifestyle habits, only 10% see diet as the most important factor for brain health.

Still, awareness is moving in the right direction.

In 2017, four in ten adults age 40-plus said they were very likely to adjust their diets to protect their brains. In 2025, that number rose to six in ten. Half say they are already trying to eat better—proof that the desire to improve is growing stronger each year.

More adults are saying they are “very likely” to change their diet for better brain health

What Gets in the Way? Real-Life Barriers to Brain Healthy Eating

Most people want to eat better. So why is it so hard? AARP’s research reveals a set of common, practical barriers that stand between intention and action:

Top Challenges:

• Cost: Many feel healthier food is too expensive.
• Convenience: Healthy options aren’t always accessible. Some say they require more preparation or they require harder-to-find ingredients.
• Motivation: One-third say advice from a doctor would help them make changes, yet only four in ten report discussing diet with their providers.
• Taste: Some simply don’t like foods typically labeled as “healthy.”

23%

Not a "healthy foods" person, dislike the taste

I try to buy the best foods within reason, also considering cost … (e.g., if extra lean meat is especially expensive, I might buy the next leanest meat).

- Age 55+

Fish was my first choice for protein, but it was more expensive compared to meat, so I did not buy it as much.

- Age 55+

I wish I could spend more money on food. The healthier the food the more expensive it is … That’s the only thing that affects my choices in food.

- Ages 40–54

I could also exclusively shop ‘healthy’ food markets and specialty stores, but they aren't always convenient.

- Age 55+

Healthy … means harder to find at convenient locations.

- Ages 45–54

Healthy can be complicated. It can mean reading labels, lots of them … Healthy also means constant change. What is healthy for us seems to change every year.

- Age 55+

I try to [eat] better … things my doctor tells me I follow to the best of my ability but as long as my family eats I don't think I really prioritize food.

- Age 55+

I want my doctor to send me home after each checkup with a clean bill of health.

- Age 55+

I have a men’s specialist…that I see routinely to identify gaps in my nutrition and/or deficiencies in my health.

- Ages 40–54

But, I am a picky eater. I don't eat fish or beans, broccoli, cauliflower, avocado, so I do struggle with diet plans.

- Ages 40–54

When I hear ‘healthy’ in describing food, I think of bland and uneventful dishes ahead.

- Ages 40–54

I KNOW that’s what healthy is, but my tastebuds won’t allow me to be quite that strict!

- Ages 40–54

But barriers aren’t only logistical.

Food is emotional and cultural. Many adults say “good meals” are defined by comfort, nostalgia, or shared experiences — sometimes overshadowing nutritional goals. In fact, eating alone and loneliness can erode healthy habits, especially among older adults. Accordingly, the USDA version of Healthy Eating for Older Adults encourages individuals to “Make eating a social event”. And AARP’s Views on Eating and Food study shows that four in five adults age 18-plus say that sharing a meal is an opportunity to socialize with others.

“ ”

I feel that some people do not choose correctly because they might be feeling down and want a comfort food which is easier to grab than making a healthy meal.

–Age 55+

“ ”

Since I am Indian and I tend to eat a lot of spicy dishes and rice and curries ... But in times of stress eating comfort food is not uncommon.

–Ages 40–54

“ ”

A good meal … makes me feel content. People and places impact this … I think a good meal provides comfort, even if it may not be the most healthy.

–Age 40–54

You Don’t Have to Be an Expert — Simple Choices Make a Big Impact

Here’s the empowering truth: anyone can begin a brain healthy diet, at any age.

GCBH experts emphasize that changing to a healthy diet offers benefits across the lifespan — and the earlier you start, the better, but it’s never too late.

Fortunately, most adults already believe that small shifts in eating habits can help preserve independence, support long term health, and strengthen cognitive well being.

“ ”

As a person at this life stage, I feel there is definitely a benefit in incorporating more of these brain healthy foods into my routine to help me keep the brain health and strength that I currently have and possibly improve it.

Even more encouraging: people don’t expect perfection. They simply want practical, accessible tools.

What could help people get started?

• Recipe apps and websites with healthy options
• Social media for quick nutrition and meal prep ideas
• Tools that offer reminders, checklists, or simple guidance
• Technology that sparks creativity—like apps that build flavorful recipes or help visualize balanced plates

Articles, books, conversations with friends, and online searches are popular ways people explore brain health on their own. In addition, one in five adults 40-plus already uses digital tools to support healthier eating, with many more open to trying them. According to AARP’s 2026 Tech Trends report, about one-third of adults 50-plus have interest in using technology to maintain brain health.

A well rounded, nutrient rich diet—full of whole foods, vegetables, fruits, lean proteins, and whole grains—is essential to supporting your brain throughout your life. There’s no single superfood or shortcut; it’s the pattern that matters most.

Whether you’re trying to improve focus, preserve memory, or simply feel sharper and more energized, your next meal offers an opportunity to nourish your brain.

You don’t need to overhaul your life.

You just need to begin.
