There’s a big misconception that your blood type is only important in the event of a transfusion. The fact of the matter is that your blood type is a key genetic factor that influences many areas of health and well-being.


Just look around you and you’ll see that some people tend to lose weight more easily, while for others, their weight is an ongoing battle. Furthermore, some people are plagued by chronic illness while others stay healthy well into their advanced years. Simply put, the answer is in your blood type.

As per the blood-type diet, there are 4 blood types:

  • Type O – the oldest blood type
  • Type A – agrarian
  • Type B – nomadic
  • Type AB – modern

How your blood type determines your diet and predicts your susceptibility for certain diseases.

According to research individuals of certain blood types may be at a higher risk for certain diseases; studies have indicated that people with blood type O have a lower risk for heart disease, however, a higher risk for developing stomach ulcers. People who are blood type A have higher risks of microbial infections, but Type A women experience a higher rate of fertility. Other studies have indicated that people with type AB and B blood have a much higher risk of developing pancreatic cancer.

People of different blood types react differently to stress.

Type A people carry higher levels of the stress hormone cortisol in their bodies, therefore, tend to produce more in response to stressful situations. People with type O blood, have a ‘fight or flight’ reaction to stress which results in the overproduction of adrenaline. Type Os take a longer time to recover from stress since it’s more hard for them to clear the adrenaline from their bodies.

Your Blood Type Decide What You Can Eat:

Type O blood:


What to eat: Have high-protein diet heavy on lean meat, poultry, fish, and vegetables, and light on grains, beans, and dairy. D’Adamo furthermore suggests various supplements to help with tummy troubles and other issues he says people with type O tend to have. Eat kelp, seafood and (in moderation) salt, which lowers your levels of iodine, thus boosting your thyroid function.

Character Traits: Focused, leader, energetic
Your Personality: The traits that best describe you are your leadership skills, extroversion, energy and focus. You consider yourself responsible, decisive, organized, objective, rule-conscious and practical. However, if you ever cheat on your diet, stop exercising or slip into a negative mindset (even boredom), watch out. You become angry, hyperactive or even manic.

Type A blood:


What to Eat: Eat plenty of fruits like berries, figs, plums, apples, avocados, pears and peaches. Pick veggies like broccoli, artichokes, carrots, greens and garlic. Fish and poultry should be limited since type As produce fewer meat-digesting enzymes, which is why they have such a hard time digesting red meat. To get protein, rely on plant protein from nuts (like nut butters), seeds, beans and soy. Because your body can easily break down and get optimal nutrition from grains, carbs and proteins, cereal, breads and pastas should be staples of your diet. Type A blood has a sensitive immune system.
What to Avoid: To balance cortisol levels (you may have high levels, which can lead to OCD, disrupted sleep, muscle loss, fat gain and insulin resistance) limit sugar, caffeine and alcohol and don’t skip meals, particularly breakfast. Stressful elements like extreme weather conditions, loud noise, overwork and violent TV and movies need to be avoided.
Character Traits: Hardworking, responsible, calm
Your Personality: You rarely get panicky. You’re responsible, hardworking, detail oriented and extremely organized. But you also have a classic “type A” personality—stressed and conscientious, craving success and perfection. You’re the most artistic of the blood types (and even a little sensitive).

Type B blood:


What to Eat: The ideal diet for you consists of leafy greens and vegetables, and fruits like bananas, grapes, plums and pineapple. Modern Bs should rely on lean red meat (like lamb, venison and beef) and fish, and choose turkey over chicken. Because of a sugar present in milk, Bs should work dairy like yogurt, cheese and milk into their diet each day.
What to Avoid: Eat grains moderately and avoid corn, buckwheat, rye and wheat since they can alter your ability to metabolize. (Same goes for nuts and seeds, so avoid peanuts, sunflower seeds and sesame seeds.)
Character Traits: Individualistic, relaxed, unconventional
Your Personality: You always stick to your goal, even when it’s against the odds. Because you follow your own rules, you’re not the most cooperative of the blood types.

Type AB blood:


What to Eat: Type AB is the rarest blood type, found in less than 5% of the population. Because ABers share traits with As and Bs, they’re able to digest a wide range of foods. However, they have type B’s adaption to meats, but A’s low stomach acid, which means meat often gets stored as fat. AB’s should eat more veggies, seafood and turkey. Red meat should be eaten sparingly. ABs, like Bs, thrive on dairy and can process eggs particularly efficiently.
Weak immune system? Try a vegetable-rich diet with a variety of carbohydrates. Snack on fresh fruits like cherries, grapes, watermelon and figs. Because you have an alkaline stomach, you might have a hard time digesting acidic foods like oranges. Seafood, like mahi-mahi, red snapper, salmon, sardines and tuna, suit you.

What to Avoid: Avoid corn and buckwheat, which are difficult for ABs to digest. Stay away from smoked and cured meats as well as chicken, veal, beef, pork or shellfish. Steer clear of caffeine and alcohol, especially when you’re stressed.
Character Traits: Difficult to read, trustworthy, volatile

Your Personality: You are hard to pigeonhole since you have traits from both ends of the spectrum. You don’t mind doing favors or helping out, as long as it’s on your own terms. You may have a special interest in art and metaphysics.
