Ethiopia: What should you eat according to your blood type?
While the premise of the diet is intriguing, two dietitians interviewed by Heathline say there isn’t enough scientific backing to endorse the blood type diet.
“There’s just not the science to support it, so we don’t look at blood type in making those considerations,” Liz Weinandy, a staff dietitian at The Ohio State University Wexner Medical Center, told Heathline. “Looking at someone’s blood type definitely tells us something about the person, but should it dictate the foods that they eat? Probably not.”
The blood type diet asserts that blood type can determine which foods will work best with a person’s internal chemistry.
For example, those with type O blood are said to do best with a largely plant-based diet with lean meats, cutting out wheat and dairy.
For those with type A blood, the diet recommends carbohydrates and cutting out meat.
