Blood Type B Diet

Blood Type B Diet: Certain diet methods are said to be able to maintain the health of those of you who have blood type B. Just know what foods are recommended and should be avoided, as well as tips on having this healthy diet.

What is this?

The blood type diet was introduced by a naturopathic expert, Peter J. D’Adamo, through his book Eat Right for Your Type: The Individualized Blood Type Diet Solution.

In the book, it is stated that the blood type B diet is omnivorous, meaning that it can consume both plant and animal food sources. There are not many food restrictions when implementing this diet. The reason is that Doctor D’Adamo believes blood type B tends to have a stronger immune system.

Balancing the intake of nutrients from both plant and animal sources is the key to the success of the blood type B diet. On the other hand, an unbalanced intake of plant and animal sources, for example, one in excess, will disrupt the health of the body.

Potential Benefits

The following are some of the advantages of this diet.

1. Helps maintain immunity

Quoting from the journal PLOS One (2014), someone with blood type B tends to have lower levels of e-selectin. E-selectin is a type of protein that is active when an inflammatory or inflammatory process takes place. This protein helps the body’s defense system.

Therefore, the blood type B diet usually emphasizes a balanced diet, which is believed to increase levels of this e-selectin.

2. Prevent the risk of chronic disease

Each blood group reflects the presence or absence of an antigen (A, B, O, and AB) on blood cells. This antigen is believed to affect a person’s risk of developing chronic disease.

Well, people with blood type B have a higher risk of developing diabetes. So, this diet helps prevent diabetes.

3. Launching metabolism

The blood type B diet encourages you to reduce processed foods and maintain a balance of nutritional intake. You are advised to consume more vegetables, certain types of meat, and low-fat dairy products in balanced portions.

Eating a balanced, nutritious diet will support your body’s metabolism while maintaining your health.

4. Make the body fitter

In addition to implementing the blood type B diet, you also need to lead a more active lifestyle. You must not only balance your nutritional intake, but you must also exercise regularly. Body fitness will be more awake as a result.

Regular exercise can also optimize diet results, especially if this blood-type diet has been followed to lose weight.
