The Dukan diet was designed by Dr. Pierre Dukan, a nutritionist and eating behavior specialist having 35 years of experience in clinical nutrition. The Dukan diet is very similar to the system of HyperProtein.
The diet included low amounts of high-fat dairy products, red meat, organ meat, and butter. Foods in this diet that appeared to fight Alzheimer's disease were salad dressing, nuts, fish, poultry, tomatoes, fruits, and cruciferous and dark and green vegetables. Researchers say the combination of nutrients and foods in this particular dietary pattern may fight Alzheimer's in a variety of ways.
As far as eating more vitamin E-rich foods to reduce risk of Alzheimer's disease, Sano says other factors may be at play; meaning that it may not be the E per se as much as the fact that people who eat diets that are rich in vitamin E and other antioxidants may eat less fat and sugar.
