Diet with Whole Grains May Reduce Alzheimer’s Risk

It appears that a ‘grain brain’ may be protective against Alzheimer’s. Researchers studied the relationship between eating patterns and Alzheimer’s in 923 retired adults in Chicago over an average of 4.5 years.  The scientists rated participants’ diets based on how closely they adhered to the Mediterranean diet, the DASH diet (a healthy diet used to treat hypertension that emphasizes fruits, vegetables, whole grains, low fat dairy, and limited sweets and salt) and the MIND diet. The MIND diet is a hybrid Mediterranean-DASH diet that emphasizes foods associated with brain health, including 3 servings per day of whole grains (more than any other food group), along with green leafy vegetables, berries, nuts, olive oil, and fish. The groups most closely following either the MIND diet or the Mediterranean diet cut their risk of Alzheimer’s dementia by more than half (53% for MIND and 54% for Mediterranean), while those closely following the DASH diet were 39% less likely to develop Alzheimer’s. Even those moderately following the MIND diet were at a 35% lower risk.
