Dr. Peter DÁdamo, the author of “Eat Right For Your Type”, claims that there is a chemical reaction between our blood and the food we consume. This chemical reaction is a part of the genetic inheritance and is caused by Lectins.
Lectins are abundant and diverse proteins which have agglutinating properties that affect blood and can be found in foods.
Therefore, if you consume food which has protein lectins that are not suitable for your blood type antigen, the lectins target an organ or bodily system and start to agglutinate blood cells there. Luckily, most lectins are not life-threatening but can lead to various health issues, especially if they are not specific to your blood type.
For the most part, your immune systems protect you from lectins. Ninety-five percent of the lectins you absorb from your typical diets are sloughed off by the body.
Yet, at least five percent of the lectins you eat are filtered into the bloodstream and different reactions in various organs. Therefore, the blood type diet has been created to target these specific factors.
This is how to eat according to your blood type:
This blood type is believed to be a descendant of our ancestors who were hunter-gatherers, and their diet consisted mostly of animal protein as they needed to survive their strenuous lifestyles.
Therefore, people with this blood type should consume fish ( like bass, cod, halibut, sole and rainbow trout ), chicken, turkey, lean beef, lamb, seafood, kelp, and salt, which will reduce the iodine levels and thus optimize the function of the thyroid.
On the other hand, they should avoid germ and wheat products, dairy, eggs and gluten, beans and legumes. Also, they should avoid or limit the consumption of cruciferous veggies such as cabbage, Brussels sprouts, cauliflower and mustard greens as they impede the thyroid function.
Hunter-gatherers started to expand their diet and include herbs, vegetables, and fruits when they began to thin out. People who belong to this blood type have the needed digestive enzymes and bacteria to digest grains and plants.
Hence, if you are one of them, your diet should include apples, peaches, berries, figs, plums, avocados, and pears, as well as vegetables, like carrots, greens, broccoli, artichokes, and garlic. Also, you should limit the intake of poultry and fish as your body produces fewer meat-digesting enzymes.
On the other hand, in order to supply the body with the needed protein, you should rely on plant protein from seeds, nuts (like nut butters), beans and soy.
Your digestive system can easily break down and get optimal nutrition from proteins, grains, and carbs, so pasta, cereal, and bread can be staples of your diet.
Yet, in order to regulate the levels of cortisol in the body, which can lead to OCD if in high amounts, weight gain, disrupted sleep, insulin resistance, and muscle loss, you should not skip meals and reduce the intake of caffeine, sugar, and alcohol.
This blood type emerged when people with the blood type) moved to the Himalayas and became nomads, domesticating animals and consuming meat and dairy.
If you belong to this blood type, your diet should include fish and lean red meat (such as lamb, venison, and beef), turkey, cheese, yogurt, and milk.
You can freely consume leafy greens and vegetables, as well as fruits such as pineapples, bananas, grapes, and plums. Yet, you should avoid grains, buckwheat, rye, corn, and wheat, as well as seeds, nuts, peanuts, sesame seeds, and sunflower seeds, because they can change your metabolism.
This blood type is the newest and the rarest of all. Only 5% of the population belongs to this group, and they share the traits with As and Bs. Therefore, they can consume a wider range of foods.
Yet, note that these people have the adaptation to meats as group B, but the low stomach acid of the blood type A, meaning that meat often gets stored as fat.
They should consume seafood, turkey, and vegetables, eggs, and dairy, but consume red meat in moderate amounts. These people can easily boost their immune system by consuming a diet high in veggies and various carbohydrates.
They can also enjoy fresh fruits such as grapes, figs, cherries, and watermelon, as well as some seafood kinds, such as salmon, tuna, mahi-mahi, red snapper, and sardines.
On the contrary, these individuals should avoid corn and buckwheat, as they are digested with difficulties, as well as smoked and cured meats, shellfish, chicken, veal, beef, and pork. Moreover, they should limit or completely eliminate the intake of alcohol and caffeine.
