Diet Linked to 'Reversing' 18 Years of Brain Aging: Alzheimer’s Study

A new study published in Neurology suggests that adopting dietary patterns like the Mediterranean and MIND diets may slow brain aging by up to 18 years. Participants who followed these diets showed less plaque buildup in the brain, a characteristic of Alzheimer’s disease. Key components of these diets include green leafy vegetables, fish, legumes, and olive oil. For example, consuming seven or more servings of green leafy vegetables per week is linked to a significant reduction in brain aging. These studies confirm previous research highlighting the benefits of plant-based foods and anti-inflammatory elements for brain health.
