Blood Type O Food List (And Foods to Avoid)

Blood Type O Food List – Overview

Perhaps you only remember your blood type when it is time to receive a blood transfusion or donate blood. But did you know that there is a possibility that you could live a healthier life by eating according to your blood type?

According to a naturopath named Peter D’Adamo, eating foods that suit your blood type can help you reduce the risk of developing certain health conditions as well as achieve better overall health.

In this article, we are going to focus on the blood O diet. Keep it here to learn a thing or two about it.

What is the O blood Type?

Blood comprises numerous components all of which are necessary for the optimal functioning of your body. We are talking about things like platelets, white and red blood cells, as well as plasma.

Other than that, blood also has antigens which are the substances found on the surface of cells and their function is to trigger the immune system so that it attacks foreign organisms and compounds such as bacteria.

These antigens can also make the immune system attack blood types with different antigens.

Now blood is classified as O, AB, B, or A and can either have the rhesus factor or not to which it is denoted positive or negative.

Since we are talking about blood group O, you want to note that it is a universal donor type since it does not have the rhesus factor neither does it have A or B antigens.

Foods for Blood Type O

Dr. D’Adamo insists that blood type O individuals should eat foods rich in protein with minimal carbohydrates.

Some of the foods that he recommends for this diet include:

Animal Proteins

The blood type O diet plan requires individuals to consume beneficial animal protein including venison, veal, mutton, lamb, and beef.

People following the type O blood can eat most meat products and this includes cold-water fish.

Dairy

Nuts

Beans

Individuals in blood group O should also consume beans as part of their protein intake. Some of the beans allowed include black-eyed peas, pinto beans, and adzuki beans.

Now, this diet does restrict grains but there are some exceptions including millet, kasha, Kamut, rice, buckwheat, and amaranth.

Foods to Avoid

Others like wheat containing gluten lead to autoimmune and inflammatory responses in some individuals.

Some of the foods to avoid when on this diet include:

Fruits

Some of the fruits to be avoided while on this diet include honeydew, cantaloupe, melons, oranges, avocado, rhubarb, blackberries, strawberries, tangerines, and coconut.

Does it Work?

After all, is said and done, one would want to know if the blood type O diet works seeing as it can be hard to follow and restricts a lot of foods that most people enjoy.

Well, Dr. D’Adamo states that when blood mixes with certain foods especially those that contain a protein known as lectin, a chemical reaction occurs.

Now, Lectin directly affects the digestive tract as well as the blood. This protein compound then sticks to cells in the body and causes them to bind together. In turn, you may experience hormonal disruptions.

The effect of that on the body can be compared to what happens when the body recognizes a foreign substance and tries to attack it.

According to the naturopath, individuals with different blood types respond differently to certain foods and the lectin they produce. This is why there are different foods for different blood types.

That said; there is no scientific evidence suggesting that lectins affect individuals in certain blood groups differently.

According to a 2014 study, following the blood type O diet is shown to have diminished triglyceride levels in the blood.

However, the authors did conclude that the reduction in triglyceride levels was caused by other factors not related to individual blood groups.

Summary

There may be some truth to the claims that food consumed affects the health of individuals in different blood groups but there is no solid scientific evidence to back those claims up.

Individuals who have adhered to blood type diets have in the past reported improved health but there is no way to ascertain that it was because of the diets.

For all we know, it could be because they were consuming healthier food in general.

You must observe how your body responds to what you eat or drink if you are to know what works best for you.

Ultimately, you want to adopt a nutritious and well-balanced diet as well as exercise and take the necessary supplements.
