There is no magic bullet diet. Diet can reduce your risk of Alzheimer's but not eliminate the risk. I have concluded that people should try to abandon the American diet that is full of red meat, artificial sweeteners, and all kinds of food that does not contribute to your health. This is why people in Japan, Europe, etc outlive Americans. I have decided to limit my red meat to two meals per month. However, I also decided to eat at expensive steak houses for those two glorious steak meals because I also need to enjoy life. The rest of my meals will be healthy plant-based, low fat, low sodium, low cholesterol, low artificial preservatives and sweeteners and then take my chances. I look forward to enjoying two glorious steaks with family and friends every month.
