Higher adherence to Mediterranean, DASH, or MIND dietary patterns is associated with less cognitive decline and a lower risk of Alzheimer's disease in adults aged 40 and older.
Adopt a dietary pattern rich in plant-based foods, healthy fats (like olive oil), and lean proteins. The MIND diet, which emphasizes berries and leafy greens, shows the strongest association with reduced Alzheimer's risk. Consistency in high adherence to these patterns is key for cognitive protection.
current scientific evidence suggests that higher adherence to the Mediterranean, DASH, or MIND diets is associated with less cognitive decline and a lower risk of AD, where the strongest associations are observed for the MIND diet.
