Dietary guidelines based on blood type

People say, blood type can affect personality; so it is not surprising that many people associate a person's attitude with their blood type. But unfortunately, until now there is no strong evidence that suggests a relationship between blood type and a person's personality. On the contrary, there have been many studies that have shown a link between blood type and the risk of certain diseases, such as heart disease, cancer, and other diseases related to the immune stress response.

According to Peter D'Adamo in his book entitled Eat Right for Your Type it states that blood is the most basic food for your body; so that different blood types will react differently to the food you eat. Therefore, Peter D'Adamo provides food recommendations based on blood type as follows.

Diet for blood type A.

Blood type A tends to have a more sensitive immune system, so too much pressure can weaken their immune system faster than other blood groups. They have lower levels of stomach acid so they tend to have a hard time digesting foods that contain animal protein and fat.

They are more advised to consume foods that contain vegetable protein such as soybeans, tempeh, peas, seeds, vegetables, and fruits that are alkaline such as avocado, dates, apples, berries, and others. However, because people with blood type A tend to be sensitive to lectins, they are not recommended to consume potatoes, tubers, as well as papayas, mangoes, and oranges which can trigger diabetes.

Diet for blood type B

Blood type B is more flexible than other blood groups, especially A and O because they can eat foods that contain animal and vegetable protein. They are encouraged to increase their consumption of red meat, green vegetables, eggs and low-fat dairy products.

However, owners of blood type B are not recommended to consume chicken, wheat, corn, beans, tomatoes, peanuts and sesame seeds because these foods can affect the body's metabolic processes which can lead to fatigue, fluid retention, and hypoglycemia.

Diet for blood type O

People with blood type O tend to have high stomach acid levels and have the ability to digest protein and fat easily. These digestive factors greatly enhance Type O's ability to metabolize the cholesterol in animal products more efficiently and better assimilate calcium.

Owners of blood type O are not recommended to frequently consume milk and its preparations because these products are difficult for the body to digest. Because they tend to be allergic to gluten, they are not recommended to consume cabbage, cauliflower, and wheat which can inhibit thyroid hormone and adversely affect insulin which can inhibit the body's metabolic system.

A healthy diet based on blood group O is alkaline fruits such as avocado, apples, dates, garlic, carrots, celery, as well as beef, lamb, turkey, chicken, eggs, nuts and seeds, and seafood because it can increase hormone production.

Diet for blood group AB

Just like blood type A, people with type AB blood have low stomach acid so they are not recommended to eat meat because their digestive system has difficulty accepting these foods. They are also discouraged from consuming caffeine and alcohol especially when they are under stress. Foods that are recommended for consumption are tofu, milk, green vegetables, and seafood which are the best sources of protein such as salmon, sardines, tuna and red snapper.

Is a diet based on this blood type really effective?

The diet was created by Peter D'Adamo to help you lose weight or diet according to blood type. But unfortunately, a study in 2013 stated that there was no strong evidence to support the benefits of a diet based on this blood type.

On the blood type diet, you will avoid some processed foods and simple carbohydrates that may help you lose weight; it's just that, this has nothing to do with blood type. Even now, there is no research that proves that the blood type diet can aid digestion and provide more energy.

American Diabetes Association it warns you not to focus on certain foods and it is not advisable to avoid certain food groups unless you are allergic to or have restrictions on them.

However, if this blood type diet interests you, what you need to remember is that this diet is structured as an alternative recommendation for weight loss, not as an effort to restrict food based on your blood type.
