This Doctor Is a Blood Type Expert—These Are the Foods He'd Never Cook With

Most health and nutrition experts would agree that there's no one diet that's suited to every person, but Peter D'Adamo, a naturopathic physician and author of the best-selling book Eat Right 4 Your Type, says there's one exception to this rule. "The blood type diet is right for everyone, as its overarching concept is that people are individuals and have individual dietary, exercise, stress-reduction, and health-management needs," he tells MyDomaine.

The blood type diet follows the premise that our genetics play a big role in determining our health and well-being. Knowing your type—O, A, B, or AB—can help you better understand how your body reacts to food, what your natural stress response is, and even whether you're susceptible to disease. "Studying blood type and genetics has shown me and many other doctors across the world just how unique people are inside," says D'Adamo.

So how do you know if your current diet is aligned with your blood type or if you need to overhaul your shopping list? "Some of the most apparent signs that a diet is not working are a general sense of sluggishness and weight," he says. While many experts remain divided about the diet's validity, D'Adamo says the results speak volumes. "An overwhelming amount of self-reported outcomes from people following the blood type diet include not only weight loss, but unexpected surprises like a reduction in allergies, inflammation, chronic digestive issues, and joint discomfort," he says. "It's not just a weight-loss program."
