Seafood, the second most concentrated animal protein, is best suited for type O's. Fish is packed with protein, vitamins, and nutrients that can lower blood pressure and help reduce the risk of a heart attack or stroke.
According to the diet, people with type A blood may consume most kinds of seafood with the most beneficial being: carp. cod. grouper.
Meat, Poultry and Seafood
D'Adamo recommends that people with type A blood eat plenty of fish, including salmon, sea or rainbow trout, red snapper, cod and mackerel. Chicken and poultry can be eaten up to two times a week, but D'Adamo says to avoid all beef, pork, game meats and shellfish.
Salmon is beneficial for Blood Types A, AB and B and neutral for Type O, making it one of the most universally healthy seafood options for Blood Type Diet followers. Wild-caught salmon is a great source of nutrients, including Omega-3 fatty acids; a kind of nutrient that many people are deficient in.
Type AB reacted most to nuts and beans, seafood, eggs, and dairy; while A2B also reacted to gluten grains. Type Rh‐negative was most reactive to eggs, dairy, nuts and beans, and gluten grains. The highest IgE scores were among types B and Rh‐negative.
When it comes to drinks, caffeine and alcohol aren't recommended for type O people. Fizzy drinks, tea, coffee and all types of wine, beer and spirits are restricted on this particular blood type diet. According to D'Adamo, people with blood type O should avoid caffeine because it increases their adrenaline levels.
Blood Group: B
Avoid: Corn, buckwheat, tomatoes, peanuts, sesame seeds, wheat, chicken, fish and eggs.
Furthermore, avocado is high in fat. People with blood type O are recommended to keep it away from their diet.
Recommended Herbs, Spices & Condiments for Blood Type O
Parsley soothes the digestive tract, as does warming spices such as cayenne pepper. Black pepper, white pepper, and vinegar create a feeling of discomfort to type O's.
People with blood type A will be able to easily digest yogurt, kefir, goat milk products, and select cheeses (such as feta and goat cheese.) When it comes to healthy fats, most nuts are okay for blood type A.
Type O: Also known as the "hunter," D'Adamo purports that people with this blood type should eat a high protein diet rich in red meat, fish, poultry and some fruits and vegetables. This precursor to the paleo diet cautions type Os against eating grains, legumes and dairy products.
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
People with O blood type should follow a high protein diet, full of lean meats, fish, eggs, kale, lettuce, broccoli, onions, pumpkins, turnip, red peppers, okra, garlic, ginger, cherries, figs, plums, prunes, raspberries, cranberries and gooseberries.
A good breakfast for people with O positive blood type should consist of protein-rich foods like eggs, lean meats, and nuts. It is also advisable to include fruits and vegetables with low glycemic index to provide essential vitamins and minerals.
How does hair growth change with blood group? It was concluded from recent study that maximum hair growth occurs in O+ blood group and minimum hair growth occurs in B+ blood group.
Blood Group: O
Avoid: Spinach, cabbage, corn, cauliflower, eggplant, mushrooms, oranges, kiwi, strawberry, blackberry, coconut, green peas, peanut butter and wheat starch.
Dairy. Although people looking to follow the blood type O diet should generally avoid dairy and eggs, they can occasionally consume the following products: butter. cheeses, such as farmer, feta, mozzarella, and goat's cheese.
White and red potatoes -- a category that D'Adamo's website uses to include all sizes of red potatoes, both long and round white potatoes and russet potatoes -- are not recommended for people with type-O blood. They are listed as a food to avoid for both secretors and nonsecretors.
Dairy & Eggs
Other type O's may eat an occasional egg and small amounts of dairy, but it is generally a poor protein source for type O's. Instead, use non-dairy milk alternatives, including soy, rice, and almond milks. Soya milk and cheese are excellent high-protein alternatives for type O's.
Type O people digest protein and fat better than other blood types. They can have chicken, fish, eggs, tofu, turkey, seafood, beef, spinach, sweet potato and broccoli, pineapple, poached pears and pumpkin, walnut, beans, buckwheat, pinto beans and pumpkin seeds.
AVOID distilled liquor, seltzer water, sodas (cola, club, diet, etc.).
Avoid barley malt sweeteners, cornstarch, and cinnamon, as they tend to be stomach irritants. White and brown sugars, honey, and molasses respond in a neutral way to the type B digestive system; consume in moderation.
When it comes to dairy products, an individual with type-B blood is said to benefit most from yogurt, low- or nonfat milk, goat milk or cheeses such as mozzarella, ricotta, cottage, feta or farmer cheese. These, along with eggs, supposedly contribute to efficient metabolism for type-B people.
