Type O Diet – What to Eat and What to Avoid

Meat & Poultry 

Type O thrives on animal protein. Think lean, clean, and grass-fed. 

Great options: Beef, lamb, turkey, chicken, buffalo, venison, duck, rabbit 

🚫 Skip: Bacon, pork, ham, goose


Seafood
 

Seafood is your friend—just watch out for the bottom-feeders and heavily processed stuff. 

Most are good! Especially fresh, wild-caught options 

🚫 Avoid: Catfish, caviar, pickled herring, smoked salmon, octopus, barracuda


Dairy & Eggs
 

Not your best buddies. Go easy. 

Limited: Butter, feta, goat cheese, mozzarella, soy milk 

🚫 Avoid: Most cheeses, milk (even skim), yogurt, ice cream, kefir


Oils & Fats
 

Stick to oils that your gut loves. 

Best: Olive, flaxseed, cod liver

Nuts & Seeds
 

Handy snacks—but some are better than others. 

Good picks: Pumpkin seeds, walnuts, almonds, sesame, sunflower 

🚫 Skip: Peanuts, cashews, Brazil nuts


Beans & Legumes
 

Okay in small doses. Some are harder to digest. 

Moderate: Black-eyed, pinto, green beans 

🚫 Avoid: Kidney, navy, tamarind beans; all lentils


Grains, Cereals & Bread
 

Type O’s usually don’t get along with wheat. 

Choose: Rice (brown, white, wild), millet, buckwheat, spelt, rye, Ezekiel bread 

🚫 Avoid: Whole wheat anything, cornflakes, oats, wheat bran


Vegetables
 

Go big here—but skip ones that mess with your thyroid. 

Load up on: Spinach, broccoli, kale, garlic, onions, sweet potatoes, seaweed 

🚫 Steer clear of: Cabbage, Brussels sprouts, cauliflower, eggplant, corn, red/white potatoes


Fruit
 

Sweet relief! Just a few to avoid. 

Enjoy: Berries (not strawberries), figs, apples, grapes, papaya, pineapple 

🚫 Skip: Oranges, blackberries, melons (except watermelon), strawberries


Drinks
 

Hydrate wisely. 

Try: Veggie juices (carrot, celery, etc.), pineapple juice, herbal teas 

🚫 Avoid: Orange juice, apple cider, soda, coffee


Spices, Condiments & Teas
 

Natural, clean flavors win. 

Go for: Cayenne, garlic, kelp, parsley, turmeric, dandelion or ginger teas
