What is the Blood Type Diet?

The blood type diet is a type of eating plan that is all about choosing the foods according to your specific blood type to achieve optimal health and wellbeing. It was created by naturopathic physician Peter D’Adamo and based on the theory that certain proteins (lectins) in foods can trigger negative reactions in your body if they’re not compatible with your blood type. These reactions are believed to potentially lead to serious health issues like heart disease, kidney problems, and even cancer. As such, by eating a diet based on your blood type, you can increase your health and even reduce your risk of developing serious health problems.

Now, unlike traditional diets, the blood type diet doesn’t outright ban any particular foods. Although, it does emphasize that certain foods are more ideal for specific blood types. There are also other healthy eating suggestions, such as limiting sugar and processed foods, but the main focus is on eating specific to your blood type.

The blood type diet also incorporates exercise suggestions based on your blood type for a comprehensive plan for achieving optimal health.

But what will you be eating and how will you be exercising, you ask? Well, it depends on your blood type.

As such, it’s suggested that eating an organic, vegetarian diet paired with soothing activities like yoga and tai chi will bring the best results. You may also want to completely avoid dairy, so you can focus the majority of your diet on eating an abundance of delicious and nutritious fruits, vegetables, grains, beans, legumes, nuts and seeds.
