Experts say healthy food choices tied to the MIND diet may help lower dementia risk, and Jackie Bridson singled out fatty fish, leafy greens, berries, walnuts, and olive oil as foods linked with better brain health and function. The finding points readers toward a pattern, not a single ingredient, as newer research tracks lower risk with better adherence.
Jackie Bridson and MIND
Bridson, a registered dietitian focused on women’s health and longevity, said, "For brain health specifically, there are a handful of foods with quality research behind them" and, "Components of the MIND diet, including fatty fish, leafy greens, berries, walnuts, and olive oil have been associated with better brain health and function." The MIND diet stands for Mediterranean-DASH Intervention for Neurodegenerative Delay and combines elements of the Mediterranean diet and the DASH diet.
Jordan Weiss said, "On the research side, there is no food that works in isolation" and added, "What consistently shows up in the evidence is the overall pattern, and the most studied one for the brain is the MIND diet." That framing matters for readers trying to decide whether to change one habit or several, because the diet is presented as an overall approach rather than a list of isolated items.
2024 and 2025 research
Research published in 2024 found that participants with the greatest adherence to the MIND diet had a 4% reduced risk of cognitive impairment compared with those with the lowest adherence. A study published in 2025 found that participants who improved their adherence to the MIND diet over a 10-year period had a 25% lower risk of dementia compared with those whose adherence declined over time.
Dale E. Bredesen said, "When it comes to brain health, the foods you eat have a major impact," and recommended foods high in folate such as leafy greens, broccoli, and Brussels sprouts. Folate-rich foods fit the article’s mechanism-level explanation: they supply a nutrient linked to lower homocysteine, a compound often discussed in brain-health research, without turning any single food into a stand-alone solution.
Nicole M Avena and caffeine
Nicole M. Avena said, "Coffee and green tea both contain caffeine, which has been shown to improve cognitive function by helping to solidify memories" and, "Tea and coffee can also help with short-term memory boosts." The FDA recommends up to 400 mg of caffeine per day as safe, and the article says that amount is about the caffeine in two grande Americanos at Starbucks.
Poultry such as chicken or turkey add lean protein, choline, and iron that support cognitive function, while The American Hearst Association suggests lean meat low in saturated fats over red or processed meats to keep cholesterol at a heart-healthy level. Citrus and citrus juice contain flavanone, described in the source as a plant-based compound with antioxidant properties, giving readers another way to build a brain-health-focused pattern without treating any one food as enough on its own.
For readers, the practical takeaway is to think in combinations: leafy greens, berries, walnuts, olive oil, fish, poultry, coffee, and green tea can fit into one pattern, but the evidence cited here favors sustained MIND diet adherence over a single swap. The open question is which specific 2024 and 2025 studies set the size of that risk reduction and how strongly they measured the effect.
