Dietary Principles Based on Blood Type
Scientists have long studied and discovered a crucial relationship among blood type, diet, and health.
Each blood type possesses specific antigens that react differently with various substances, especially plant lectins. Plant lectins are proteins attached to food that can cause blood coagulation. Different foods contain different types of plant lectins. If they react with blood antigens, they can damage red and white blood cells, gradually triggering various issues and harming the health of the intestines, nervous system, and other organs—explaining why some people's diets seem scientific yet fail to bring true health.
After years of research, scientists concluded that certain plant lectins are compatible with specific blood types. Based on this principle, personalized food lists can be created to determine which foods are suitable, unsuitable, or should be limited for each blood type. When plant lectins match blood type antigens, they greatly benefit health.
