Nutrition by Blood Type

Nutrition is a complex issue that has been on everyone’s agenda since the existence of mankind and includes a wide variety of variables. With the developing trends, different perspectives on nutrition have been gained, and there have been many alternative diets. Gluten-free diet, ketogenic diet, intermittent fasting diet and many more… While we know more or less about so many diet types, it is getting harder to find the right diet for ourselves day by day.

In addition to the popular diets I mentioned above, have you ever heard of blood type nutrition? Especially one of the trends in nutrition and diet lately! So, what is the truth of this ‘feeding by blood type’? Does it really have scientific validity? If yes, which blood group, what should I pay attention to? The answer to all these questions is in this article through the eyes of an expert!

Is there a diet type called Nutrition Based on Blood Type?

Contrary to what is known, there is no scientific equivalent of nutrition according to blood type in the literature! We can explain this situation for many reasons.

The most important of these is the fact that nutrition is personal! Humans have four different blood types biologically; A, B, AB and 0 blood groups. These groups are determined by the presence of antigens in our blood. Assuming that nutrition is shaped according to these blood groups, we would talk about only 4 types of nutrition for years, and we would recommend the same diets to people with the same blood group. But nutrition is unique to the individual, just like our fingerprints. Because each individual’s metabolism, existing diseases, medical history, relationship with food, living standards and food preferences differ. If people of the same blood group have different metabolic problems or have different food preferences, we cannot impose a uniform diet just because they have that antigen in their blood.

When the subject is nutrition and diet, the blood values ​​of the clients are taken into account, not the blood types. For example, fasting blood sugar, triglyceride, HDL and LDL cholesterol values, hormones such as urea and creatinine, ALT, AST, TSH, various vitamin and mineral values ​​are the laboratory findings that we consider when planning the diet of the clients. In addition to these, many factors such as the person’s lifestyle, previous or chronic diseases, food allergies and intolerances, physical activity level, age, gender, dietary pattern and preferences are taken into consideration. For this reason, it is not scientifically possible to count blood groups among these factors when creating a healthy diet plan for individuals.

When it comes to weight control, it is necessary to base the calorie balance. If the person creates a calorie deficit for a while, that is, if the calories they consume are more than the calories they consume, physiological weight loss occurs. On the contrary, we can talk about gaining weight. It would be meaningless to talk about the role of antigens in the blood in this balance, where sports, nutrition and psychology affect multidisciplinary.

Unfortunately, I hope this article has been enlightening for all of us, as I have come across a lot of wrong content on the internet and various platforms on this subject. My advice is; As in every other subject, we should stay away from all non-scientific information about our nutrition and health.

Stay tuned for questions and more on the subject! Healthy days
