The choice of food based on an individual's blood type is the concept behind the best-selling book by Naturopathist Peter D'Adamo Eat Right for Your Type . Originally published more than 20 years ago, the revised editions of the book are becoming increasingly popular.
Diets with unique eating habits like D & # 39; Amanos are based on the premise that individuals process what is eaten differently because of the remaining traits and genetics of ancestors and blood type. Each blood type has different needs as well as certain foods that should not and should not be consumed. Dr. D & # 39; Adamo suggests that eating can make an individual healthier by blood type, reducing the risk of illness, losing weight, and even slowing down the aging process.
What are you eating?

Negative Blood Testing
I try to describe the positive aspects of a nutritional plan, but in this case I think it's important to start with negative ones. My main concern is that there is little research to support the idea that eating for a particular blood type affects one's health. In fact, a comprehensive review of 2013 blood group diet research published in the American Journal of Clinical Nutrition found that "there is currently no evidence to confirm the alleged health benefits of blood type diets." And when I examined the published articles more closely, the majority was based either on the opinion or the narrative – not based on evidence.

In addition, recommendations for each blood type indicate avoiding and restricting various nutrient-rich foods such as dairy products, beans, some nuts and seeds, poultry and pork. an approach that seems restrictive and somewhat pointless, as there is little evidence that a person can make health improvements by eating for blood type. I do not think this diet could hurt most people, but proper diet planning is needed to ensure that adequate nutrients such as calcium, vitamin D, iron and vitamin B12 are consumed due to the limitations in each plan.

Positive Results of the Blood Type Diet
Although there is limited research to suggest that this approach is necessary, a dietary change in the blood could improve the diet Overall, quality means many. The reason is that in all four plans, whole, minimally processed foods and processed foods with added sugars, reduced nutrients and / or added fats are emphasized. In a recent experimental study in which the researchers looked at the effects of food by blood type on heart disease markers such as triglycerides, insulin, cholesterol and blood pressure, the study found that blood diets showed some beneficial improvements in these risk factors. However, these findings were associated with improved nutrition and were not thought to be due to eating a particular blood type.

The blood group diets focus on eating more whole, less processed foods – especially plant foods – and these are the things that are Almost anyone could benefit from it. Other positive aspects in Dr. D'Amano's book is about incorporating activity and stress reduction and not finding calories, macros or other numbers. However, as a nutritionist, I can not find any benefit for the blood type of food that goes beyond what you can get from a nutritional plan with all the nutrient-rich foods.
