There’s a lot of talk about personality traits and compatibility based on blood types, but did you know that there are also foods that suit each blood type better than others?

This topic has been thoroughly researched by Dr. Peter D’Adamo.

There are various theories about the origin of blood types, but the O-type origin theory is generally the easiest to understand, and Dr. D’Adamo’s theory is also based on this origin theory.

In fact, almost 90% of Africans have type O blood. From there, humans migrated across the Eurasian continent in search of food, and in Asia, they began to primarily consume grains. This shift from a meat-based diet from hunting to a grain and plant-based diet due to agriculture led to an evolutionary change in blood, resulting in the emergence of type A blood. The distribution of blood types shows that type A is common in the Middle East and Asia, while type B is more common among Europeans who moved to colder regions, a theory suggesting adaptation to cold and dairy products. Type AB is the newest, with conventional wisdom stating it has only been around for about a thousand years.

Therefore, broadly speaking, type O thrives on a meat-based diet, type B is omnivorous, and type A benefits from vegetables and grains. Generally, type O is considered the strongest among the blood types, with a higher immunity and lower susceptibility to disease. In contrast, type A has relatively lower immunity and is more prone to cancer and heart disease, as suggested by statistics.

According to Dr. D’Adamo, the difference in reaction to lectin proteins by each blood type greatly impacts health. This forms the basis of his idea that maintaining health involves eating foods suited to one’s blood type.

Incidentally, type O is the most common in the United States, while type A is most common in Japan. This also makes sense given that American diets are heavily meat-based, whereas traditional Japanese diets are based on grains and plants.

In my opinion, popular diets like the Paleo and ketogenic diets are likely to yield better results in the United States, where type O is more prevalent.
