Nowadays, there’s a new diet trend every day. So how the heck do you know which one you should follow? The truth is, it’s best to see what works for you and your body and your lifestyle. And that might take some experimentation. But what if there was a diet out there that was specifically fine-tuned for you, based on your biology?
There just might be.
Dr. Peter D’Adamo made his claim to fame when he suggested there’s a specific diet each person should abide to, basely solely on their blood type. His basis for this diet – also backed by loads of scientific studies – is that certain blood types ascertain risks for specific diseases and conditions, reactions to stress, and types of gut bacteria. Based on this, D’Adamo promotes eating in ways that compliment your specific blood type and associated risk factors.
Considered to “original” blood type, Type O folks descend from hunter-gatherers who ate diets rich in animal protein in order to fuel their intense and strenuous daily activities.
Eat: Type Os are best suited to eat things like lean beef, lamb, turkey, chicken, and fish.
Avoid: If you have type O blood, you might have some trouble digesting dairy, eggs, gluten, and wheat products. You might also struggle with digesting beans and legumes, as well as cruciferous vegetables (like cabbage, cauliflower, and Brussels sprouts).
Type As descend from our ancestors who started incorporating semi-vegetarian diets. Individuals with type A blood possess the proper digestive enzymes and bacteria required to digest grains and plants that others might struggle to break down.
Eat: Eat things like berries, figs, plums, apples, avocados, pears, and peaches. For veggies, opt for broccoli, artichokes, carrots, greens, and garlic. The optimal protein sources for this blood type are things like nuts, seeds, beans, and soy, given that type A blood comes with fewer meat-digesting enzymes. The ability to optimally break down grains as a type A means you can eat more of these.
Avoid: Steer clear of sugar, caffeine, and alcohol, and try to avoid skipping meals. Type A folks tend to have higher cortisol levels (cortisol is a stress hormone) so avoiding these stress-inducing things can help you balance out.
It is proposed that type Bs entered the scene when type Os moved to the Himalayas, where they domesticated animals and lived mostly off of meat and dairy. Today, Bs should get their nutrition from lean red meat and fish, yogurt, cheese, and milk.
Eat: As for vegetables go, leafy greens are your best bet. And your best fruits are things like bananas, grapes, plums, and pineapples.
Avoid: Try to avoid grains, corn, buckwheat, rye, and wheat since they might affect your body’s ability to metabolize.
Type AB is considered the newest and rarest blood type – less than 5% of the population boasts type AB. These folks are able to digest a lot of foods, since they share traits with both types A and B. But they mostly have type B’s ability to handle meats, but type A’s issue with low stomach acid – so that means ABs might have issues with meats storing as fats.
Eat: Go for veggies, seafood, and turkey. Specifically, fruits like cherries, grapes, watermelon, and figs are good options. In terms of seafood, mahi-mahi, red snapper, salmon, and tuna are your best bets.
Avoid: Say no to corn and buckwheat, which you’ll likely have a hard time digesting. Smoked and cured meats are a no-go, and caffeine and alcohol should be limited.
