This is the first time I’ve heard about this, but it makes sense!

The Blood Type Diet is a way of eating that suggests certain foods are better for you depending on your blood type.
Supporters of this idea believe that consuming certain foods that match your blood type can enhance your health and quality of life. The idea is that your blood type can affect how your body digests food, processes energy, and fights off illnesses. This means that people with different blood types may have specific diets that are best for them.
The history and beginnings of the Blood Type Diet.

The Blood Type Diet became well-known thanks to Dr. Peter J. D’Adamo, a natural medicine doctor, in his book ‘Eat Right 4 Your Type’ published in 1996. Dr. D’Adamo continued the work started by his father, Dr. James D’Adamo, who noticed that people reacted in various ways to specific foods and treatments. The basis of the diet is a mix of our ancestors’ history, ideas about evolution, and what we know in medicine today. It suggests that our blood type shows traits inherited from our ancestors and determines the best diet for our health.

Learning about different blood types and their unique traits.

There are four main blood types: A, B, AB, and O. Each blood type has different characteristics because of its specific antigens. Blood type A has A antigens and does not have B antigens. Blood type B contains B antigens and does not have A antigens. Blood type AB can receive blood from any blood type because it has both A and B antigens. On the other hand, blood type O can donate blood to any blood type because it lacks both A and B antigens. Understanding these variations is very important for blood transfusions and is also the foundation for the dietary recommendations suggested in the Blood Type Diet.
