What is the blood type diet?

Eat right for your book on the table

Dadamo’s 1996 book made big waves when it came out, but there is little evidence to support the idea that eating a blood type diet will improve health.

D’Adamo’s Personal Nutrition

The general motivation for the blood type diet is that there are foods that are ideal for people of different blood types O, A, B and AB. Part of the claim hinges on the idea that blood types serve as maps to our ancestors’ history and genetics, and that the foods our ancestors commonly ate fit our bodies better, even in modern times.

Below is a snapshot of the four main blood types and what D’Adamo assumes is the best diet type for each.

something like: the farmer or the farmer. According to D’Adamo, people with blood type A should avoid meat — especially red meat — and eat a plant-based diet rich in fresh fruits, vegetables, legumes and whole grains. Because of their “more sensitive immune systems,” they should also avoid processed foods and opt for organic foods whenever possible.

type B: D’Adamo calls people with blood type B “Nomads.” Type B people are encouraged to eat plants but also most meat (except chicken). The diet also warns against eating corn, wheat, tomatoes, peanuts and some seeds.

write AB: People with blood type AB, or “puzzles” as D’Adamo calls them, are a mixture of types A and B. The diet for this blood type encourages people to eat seafood, tofu, dairy, beans, vegetables, and grains but to avoid corn, beef, and chicken. D’Adamo stresses that type AB also has lower levels of stomach acid and therefore caffeine and alcohol should be avoided.

type O: Also known as “the fisherman,” D’Adamo claims that people with this blood type should eat a diet rich in protein and rich in red meat, fish, poultry, and some fruits and vegetables. This is an introduction to the paleo diet that warns Type Os against eating grains, legumes, and dairy products.

Does the blood type diet work?

So far, there is little evidence that adhering to the recommendations of a strict blood type-based diet will improve health outcomes. “The blood type diet has been debunked many times by new and improved research,” says Rios. “People who claim to be starting to feel better on this diet usually do so because they start to cook at home more and eat more whole foods and less processed foods that can improve anyone’s health.”

Most comprehensive The study was conducted in 2013 by the American Journal of Clinical Nutrition and found “no evidence to substantiate the purported health benefits of blood type diets.” However, most of the nutrition plans featured in D’Adamo’s book may be healthier than your current eating habits because they an act Focus on natural, whole, and unprocessed foods.

When it comes to health, does blood type matter?

Rios says blood type is not something dieticians consider when providing medical nutrition therapy. “As dietitians, we focus on the patient as an individual,” she adds. “Important things to consider include health history, chronic disease, current lifestyle, food allergies, food intolerances, allergies, stress, and digestion.”

Should you try the blood type diet? Is it safe?

Following a blood type diet can be “very restrictive,” says Rios, and if not directed by a registered dietitian, it can lead to other health problems. There are a lot of things to consider before you exclude certain food groups from your diet.

DiabeticsOn the other hand, it is often advised to avoid eating cheese, dairy products and other foods in large quantities. Other health conditions including IBS and iron deficiency can be exacerbated by strictly eating or avoiding certain categories of foods.

A final word on the blood type diet

While trying a nutrition plan specific for your blood type shouldn’t have any serious negative consequences (at least not for those without underlying health conditions), there is also very little evidence that doing so will improve your health in any way.

Most nutritionists suggest a balanced diet overall, including a mix of lean protein and vitamin-rich vegetables along with whole grains, nuts, and seeds. for Lose weightAnd diets like keto And the paleo Plans are known to produce quick results, but if the goal is to improve overall health, including heart health, restrictive diets often get failing grades from nutritionists, dietitians, and other health professionals.
