Scientists believe that the secret to a healthy diet is to eat according to your blood type.
The most common blood groups – 0, A, B and AB – has evolved over time, influenced by environmental conditions in which people lived during that period.
Also, the level of gastric acid and digestive enzymes are influenced by a person’s blood type. Therefore a proper diet for each blood type is necessary to help digest the food more efficiently.
Blood type 0 is the oldest one, appearing around 50,000 BC in the period in which people led a lifestyle of hunter-gatherer.
The next blood type is Group A which appeared between 25,000-15,000 BC after mankind started to adopt agriculture.
As people migrated to colder regions, where environmental conditions were more difficult, Group B emerged and spread about 10,000 years ago.
The newest blood type is AB, which evolved about 1,200 years ago as a result of the mixture between people with group A and group B.
To help you find the right diet for your blood type, we have created a complete list of foods specific to each blood type.
Eat According to Your Blood Type 0
People with this blood type must have a lifestyle similar to their ancestors who lived 30,000 years ago, meaning a diet rich in protein and a lifestyle with intense physical activity.
Also people with this blood type are more prone to certain diseases, such as ulcers and thyroid dysfunction.
People with blood type 0 have the highest amount of gastric acid in the stomach, which facilitates the digestion of meat.
This feature has its downsides and studies have shown that the incidence of ulcers is two times higher in those with blood type 0 than among other groups of blood.
It is recommended the consumption of vegetables such as broccoli or spinach to offset the acidity of the stomach, while avoiding wheat and consuming low amounts of carbohydrates.
Also, because people with this blood type tend to have low levels of iodine in their body, it is recommended a diet rich in saltwater fish and algae.
This food contain iodine, helping to smooth functioning of the thyroid gland.
Eat According to Your Blood Type A
The key factor that led to the appearance of this blood type was the struggle that our ancestors had to find food.
After they hunted almost to exhaustion the African herds, they left the ancestral continent in search of other food sources.
By adopting agriculture, their lives changed radically, and over time their body was adapted to the new source of food: carbohydrates.
Low levels of stomach acid and large number of enzymes allow a more efficient digestion of carbohydrates.
If animal proteins accelerates the metabolic rate in people with blood type 0, in people with blood type A it has the opposite effect, they feel apathetic and lacking energy after they eat meat.
If people with blood type 0 are using meat as fuel, people with blood type A stores it as fat.
Therefore it is recommended for people with blood group A to maintain as much as possible, a vegetarian lifestyle, avoiding red meat and dairy products.
Ideal food for these people are vegetables, grains, beans, seafood, nuts, seeds and vegetable oils.
Eat According to Your Blood Type B
This group of blood appeared in the Himalayas, where India and Pakistan is today. This group of blood is actually a mutation that appeared in response to climate change, as people left the hot savanna of East Africa and have adapted to the colder climates which are typical to Himalayan plateau.
Soon, this blood type became prevalent in Asian steppe tribes.
When the Mongols began to spread on the Asian continent, blood type B was already rooted.
Even today, this blood type predominate on the Asian continent. In Europe, the number of people with blood type B decreases as we move towards the west.
People with blood type B tend to adapt more easily to areas with high altitudes and, statistically, are taller than people with other blood groups.
At the same time people with this blood type tend to produce more cortisol in stressful situations.
However a person with this blood type who lives a healthy life tends to have fewer risk factors for disease and be in a better physically and mentally state than people with other blood types.
Among the foods that are not recommended for people with this blood type is corn, wheat, lentils, tomatoes, peanuts and sesame seeds.
Instead you can eat mutton, goat, rabbit and even venison. It is also recommended the consumption of green vegetables, eggs and low-fat dairy.
Eat According to Your Blood Type AB
AB is the rarest blood type there is, which can be found in less than 10% of the world population.
This group appeared 10 to 12 centuries ago, as a result of mixing blood groups A and B and is the only group that has not emerged from environmental pressures.
People with blood type AB have less gastric acid, like those in Group A, but are adapted to eating meat, as people with group B.
Because there is not enough stomach acid to metabolise meat effectively, it is stored as fat.
You should also avoid smoked meats and sausages, because they can trigger stomach cancer in people who have less gastric acid.
Saltwater fish is an excellent source of protein for people with blood type AB.
For those with this type of blood it is recommended more frequent and smaller meals to counteract digestive problems caused by the reduced amount of stomach acid and enzymes.
Stomach digestive process takes place through a combination of gastric juices and muscle contractions.
If you have low levels of digestive secretions, food will remain in the stomach for longer.
Therefore, the specialists recommends avoiding the combination of proteins and carbohydrates during the same meal to digest food faster.
This blood group has its advantages for example, people with type AB are the least prone to allergies.
So, now you know what to eat and want not to eat according to your blood type and by taking into consideration your blood group next time when you choose your diet, you will be able to create a better, healthier and more effective diet plan.
