The Blood Type Diet suggests that a person’s diet and health can be improved by consuming food types specific to their blood type, initially introduced by Dr. Peter D’Adamo in his 1996 book, Eat Right 4 Your Type. D’Adamo argues that our evolution and the presence of A and B antigens on our red blood cells contribute to digestive processes that benefit from eating the same types of food our ancestors did.
According to the Blood Type Diet:
– Type O: This blood type evolved in hunter-gatherers, who ate mostly animal protein, so a high-animal protein diet is recommended for people with type O blood.
– Type A: Type A is common in people with agrarian backgrounds, so the diet focuses on vegetables, fruits, and grains for this group.
– Type B: Nomadic tribes had type B blood, and this diet recommends a balanced combination of meats, vegetables, fruits, and grains for type B individuals.
– Type AB: This modern blood type can benefit from a combination of diet recommendations for types A and B.
Highly beneficial, neutral, and food categories to avoid are established within each diet for each blood type, categorized into twelve food groups including meats and poultry, seafood, dairy and eggs, oils and fats, nuts and seeds, beans and legumes, grains and cereals, vegetables, fruits, beverages, herbs and spices, and condiments.
To follow the Blood Type Diet, experts recommend making dietary changes slowly, gradually reducing harmful foods and increasing beneficial ones. In addition, they suggest consulting healthcare providers before making any significant dietary adjustments. The Blood Type Diet advises against drinking beverages during meals, instead recommending at least 30 minutes before and waiting at least two hours after meals for hydration.
For more specific dietary guidelines by blood type:
– Type O Diet: Focuses on lean animal protein, vegetables like broccoli and collard greens, and limited dairy products.
– Type A Diet: Promotes plant-based foods like grains, fruits, vegetables, and limits meat and dairy consumption.
– Type B Diet: Suggests a balance between lean meat, fish, dairy, nuts, fruits, and vegetables.
– Type AB Diet: Offers a combination of elements from the type A and B diets for a more balanced approach.
