It took over pinterest and facebook with its promise of perfect health by just tweaking your diet to fit your blood type. It sounded as if it were all scientifically based and even took a few people in-Cheryl Cole is said to follow the diet. The research was carried out by the University of Toronto and Dr. Ahmed El-Sohemy said that based 1,455 study particapants there was no evidence to support the theory that nutritional needs vary by blood type and the body processes food differently. Furthermore, the health markers are completely independent of blood type. The diet went viral after naturopath, Peter D’Adamo, published his book Eat Right for Your Type. D’Adamo postulates that eating according to your blood type would increase overall health and lower the risk for chronic illnesses like heart disease. It’s sold 7 million copies so far. This is the diet: The O diet: Eat meat (high protein, low carbohydrate). Cut out wheat and most other grains. Engage in vigorous aerobic exercise. Your risk factors for ulcers and inflammatory diseases, such as arthritis increase if you eat incorrectly for your type. The A diet: You should be largely vegetarian (eating a high carbohydrate, low fat diet). Engage in gentle exercise such as yoga or golf and meditate to deal with stress. Your risk factors for cancer and heart disease increase if you eat incorrectly, according to Dr D'Admao. The B diet: You should have the most varied diet of all the blood types, one including meat; yours is the only blood type that does well with dairy products. Engage in exercise such as moderate swimming or walking. Your risk for slow-growing viruses that attack the nervous system increases if you eat incorrectly for your type. The AB diet: You have most of the benefits and intolerances of types A and B, so most foods which are recommended for either type A or B will also work for you. Engage in calming exercises and relaxation techniques. You have the friendliest immune system. What we all need to take away from this is that fad diets and diets that sound too good to be true are not the solution. Moderation, vegetables, lean protein, and eating clean are the markers of a healthy diet and lifestyle. There is no magic pill or diet that’s always going to keep you healthy without some work on your part.
