Because of its strong antioxidant effect, vitamin E, a fat-soluble vitamin, may also help fight the formation of plaque buildup seen in Alzheimer's patients. Nuts such as almonds and hazelnuts, sunflower seeds, sweet potatoes and olive oil are all foods rich in vitamin E.
Omega-3 Fatty Acids
Omega-3 fatty acids s are believed to increase production of the protein LR11. High levels of this protein have been linked to preventing the toxic plaques in Alzheimer's from being made, whereas low levels are believed to be a factor in causing the disease. Cold-water fish such as salmon and sardines are high in omega-3s, and so is flaxseed oil. Many nuts such as walnuts and almonds contain high levels of omega-3s and also vitamin E, making them solid choices that do double duty in the fight against Alzheimer's.
