Blood Work: Eating by Type

By Lisa Carmerlengo

If you’re having difficulty staying on a life-altering plan, have you considered the possibility that you’re not eating for your type? Your blood type, that is…

Dr. Peter D’Adamo, author of the New York Times best-seller, Eat Right For Your Type, began a health revolution 15 years ago with his nutrigenomic diet. The success of the plan is based on your individual blood type and what you should (or should not) consume according to the traits of that particular type. For example, Dr. D’Adamo’s research found individuals with Type O blood tend to gain weight when eating gluten and dairy products and require intense physical exercise to stay in shape, while those with Type A blood are more suited to a vegetarian diet containing fresh, pure, organic foods and exercise such as yoga and Tai Chi workouts. While there is defi nitely logic to the findings, the question is: Does it work? Tamara Jacobi, a holistic health and nutrition coach at, says Eat Right For Your Type is one of her favorite dietary theories. “I was a vegetarian for fi ve years and found my energy levels to be somewhat low. I also was not losing weight as I’d hoped,” she recalls. “Upon studying holistic nutrition and the blood type diet, I discovered my blood type [Type O] is linked to a hunter/gatherer lifestyle. I immediately shifted away from grains ‒ wheat, in particular ‒ and added a variety of meats back into my diet,” she says. Guess what? Jacobi’s weight dropped much more easily, her energy levels spiked and she enjoyed a host of other health benefi ts. Not everyone is a believer though. Sharon Richter, registered dietician and certified dietetic nutritionist, says there is little research to support Dr. D’Adamo’s findings.“There is no science to back up the claims that one blood type correlates to specifi c food tolerance,” she says, adding that the blood type diet, like all diets, creates temporary restrictions and rules, which do not become lifestyle changes. While Richter agrees with D’Adamo’s recommendations to eat pure, organic and healthy foods, she says better results can be achieved by eating lean proteins, good fats, complex carbohydrates and minimally processed foods.
