A large percentage of Indian meals contain curry powder, and curry contains turmeric—a spice that has been used in Ayurvedic medicine for thousands of years. Now research shows that turmeric may help prevent Alzheimer's disease because of its antioxidant and anti-inflammatory action and immune-boosting properties—all of which may help to block or remove plaque from the brain. It's not surprising that one of the lowest rates of Alzheimer's ever reported was found in northern India.
Incorporate more vegetable and chicken curry dishes into your diet—at least one a week. And go heavy on the turmeric.
