Combination of Two Diets May Help Slow Brain Aging

<span id="StoryTextTop"/>

<p class="storyParagraph">
    A combination of two well-known dietary approaches may aid in maintaining youthful brain function, according to recent research. A study involving over 1,600 participants indicated that those who adhered closely to the MIND diet—a hybrid of the Mediterranean and DASH diets—demonstrated brain structures that appeared up to 2.5 years "younger" over a span of approximately 12 years. This finding was reported by <a href="https://www.cnn.com/2026/03/17/health/mind-diet-brain-wellness">CNN</a>. Increased adherence to the MIND diet was associated with less gray matter loss, which is crucial for memory and cognitive functions, along with a slower enlargement of the brain's fluid-filled ventricles, another indicator of atrophy.

    Specifically, every three-point increase in adherence to the MIND diet correlated with a 20% reduction in gray matter shrinkage and an 8% slower rise in ventricular size, as detailed in the <a href="https://jnnp.bmj.com/content/early/2026/03/11/jnnp-2025-336957"><em>Journal of Neurology, Neurosurgery &amp; Psychiatry</em></a>. The MIND diet emphasizes the consumption of berries, beans, leafy greens, whole grains, nuts, fish, poultry, and olive oil, while significantly reducing intake of red meat, butter, cheese, sweets, and fried foods.

    Among the findings, berries and poultry appeared to contribute significantly to the benefits observed, whereas sweets and fried fast foods were linked to accelerated brain aging. These latter foods are often rich in unhealthy fats, trans fats, and various harmful compounds, which may lead to inflammation and vascular damage, according to researchers noted in a <a href="https://medicalxpress.com/news/2026-03-mind-diet-adherence-linked-slower.html">release</a>. While the study itself is observational and cannot establish direct cause and effect, the researchers emphasize the importance of adopting an overall Mediterranean-style diet rather than relying on any single "miracle" food.
