How do B+ blood types eat?

People with B+ blood type need to follow a balanced diet that is tailored to their unique metabolic characteristics. While there is no one-size-fits-all approach, there are some general dietary guidelines that can help optimize health for those with B+ blood.

Overview of the B+ Blood Type

Around 10% of the population has B+ blood. This blood type is determined by the presence or absence of certain antigens on the surface of red blood cells. People with B+ blood have the B antigen and the RhD protein.

It is believed that different blood types evolved in response to infectious diseases. The antigens helped early humans resist infections from various bacteria, viruses, and parasites. As such, people with a certain blood type may be more or less susceptible to certain illnesses.

Proponents of blood type diets argue that people should eat foods that their ancestors with a particular blood type ate. However, there is limited scientific evidence to support the validity of blood type diets.

Recommended Diet for B+ Blood Types

While the benefits are debated, here are some dietary recommendations often made for those with B+ blood:

Emphasize Certain Food Groups

  • Meats: B+ individuals are often encouraged to eat plenty of beef, lamb, mutton, rabbit, and pheasant. Grass-fed, organic meats may offer the most benefits.
  • Dairy: Most people with B+ blood can digest dairy well. Fermented dairy like yogurt and kefir are recommended.
  • Fruits and vegetables: People with B+ blood are advised to eat a diverse mix, focusing on leafy greens, tomatoes, carrots, bananas, pineapple, grapes, and figs.
  • Grains: B+ individuals do well with whole grains like oats, wheat germ, brown rice, and millet.
  • Beans and legumes: Kidney beans, adzuki beans, lentils, and peanuts are beneficial for the B+ metabolism.
  • Fats and oils: Olive oil and flaxseed oil are recommended cooking oils. Nuts like walnuts and almonds also provide healthy fats.

Limit Intake of Certain Foods

People with B+ blood are often advised to limit their consumption of these foods:

  • Corn, buckwheat, sesame seeds, lentils
  • Chicken, turkey, shellfish, duck
  • Tomatoes, peanuts, strawberries
  • Wheat, rye, spelt
  • Cabbage, brussels sprouts, cauliflower
  • Non-fermented dairy

Sample Meal Plan for B+ Blood Type

Here is a sample one-day meal plan appropriate for someone with B+ blood:

Meal Foods
Breakfast Scrambled eggs with grilled lamb, sliced tomato, glass of kefir
Lunch Mediterranean quinoa salad with chickpeas, bell pepper, olives, feta, olive oil & lemon dressing
Snack Celery sticks with almond butter
Dinner Grass-fed beef burger on sprouted wheat bun with lettuce, caramelized onions, avocado. Baked sweet potato fries. Salad with spinach, carrots, and banana.
Dessert Fresh figs with greek yogurt

Health Benefits of the B+ Diet

A well-rounded diet rich in fresh, whole foods that aligns with an individual’s blood type may provide these benefits for those with B+ blood:

  • Optimizes digestion and gut health
  • Balances pH levels and hydration status in the body
  • Provides steady energy levels and appetite control
  • Supports a healthy inflammation response
  • Boosts immune function
  • Lowers risk factors for chronic diseases like heart disease, diabetes, and cancer

However, more research is still needed on blood type diets. Following general healthy eating principles with a variety of nutrient-dense foods can benefit most people regardless of blood type.

Tips for B+ Blood Types

Here are some other tips that may help those with B+ blood stay healthy:

  • Choose organic produce and meat whenever possible
  • Incorporate fermented foods like kimchi, sauerkraut, miso, kefir, yogurt
  • Stay hydrated by drinking water throughout the day
  • Engage in regular exercise like walking, cycling, or strength training
  • Reduce stress through yoga, meditation, or deep breathing
  • Get enough quality sleep every night


People with B+ blood may potentially benefit from following a diet high in protein, fruits, and vegetables while limiting dairy, grains, and certain vegetables. However, more research is still needed to confirm the validity of specialized blood type diets. Focusing on fresh, whole foods and healthy lifestyle factors can support overall well-being for those with B+ and other blood types.
