What can blood type O eat for breakfast?

For type-o individuals, the best breakfast options are various including: 

  • Oats with soya milk.
  • Stewed prunes.
  • Fresh figs.

It is recommended for blood type o to avoid wheat, dairy milk, and black tea. So you can find different alternatives, like vegetable milk and green tea. 

In recent years, the diet based on blood type has gained a lot of popularity as it has been proven to improve the health of people by sticking to an eating plan similar to one of your ancient ancestors. 

People with this type of blood are related to ancient hunters and gatherers, so the diet recommended for them is the one these populations used to have. However, you should talk to your doctor before changing your diet.

How many blood types are there?

Our blood type is inherited from our parents, yes, just like our hair and eye color. Each parent will provide you with one of two ABO genes, being A and B genes are dominant, and the O gene is recessive. So, if you have one A gene paired with an O gene, your blood type is A.

Depending on the presence of the Rh factor, our blood will either be positive or negative. If the Rh factor is present, then our blood will be positive; when absent, it will be negative. So, when we account for the total combinations, we end up with 8 different blood types.

  • A+
  • A-
  • B+
  • B-
  • O+. 
  • O-
  • AB+
  • AB-

It has been found that O-positive blood is the most common blood type all around the world.

What is the blood type diet?

It was in 1996 when Peter J. D’Adamo, MD. published the book Eat Right for your Type, which introduced for the very first time the concept of eating according to your blood type. The foundation of these eating plans is based on our ancient ancestors’ patterns.

According to D’Adamo, food possesses lectins, an anti-nutrient that binds with antigens present on blood cells, which leads to blood agglutination. When the blood cells clump, the risks of obesity and chronic inflammation.

Trying to reduce blood agglutination, D’Adamo designed his theory, in which different diets will be assigned according to the blood types. The creator of this theory only takes into account 4 different blood types

  • A
  • B
  • AB
  • O

People who have tried the diet say that it can be very restrictive and also, it might not be enough to meet our nutritional needs. Humans are complex and because of that, our nutritional needs will not be only based on what blood type we have.

Is the blood type diet effective?

Even though the idea of having a specific diet according to your blood type is innovative, there is no scientific evidence that supports it. Until now, scientists haven’t found a link between your blood type and the recommended diet.

However, there is a positive side to this eating plan. The blood type diet avoids processed foods while promoting exercising and eating whole foods, which surely can improve your health.

But let me tell you that these principles are not new but they have been recommended by many doctors and nutritionists. 

What can you eat with the o-type diet?

Unfortunately, the blood type diet can be very restrictive, so there are very specific items that you need to avoid. Let’s start with the things you are encouraged to eat in this diet.

Fruits are basic for our fiber and carbs intake, but some options can be better for your health, according to the D’Adamo theory. The forbidden fruits are strawberries, oranges, and blackberries. Instead, people with type O blood should eat

  • Dried figs.
  • Plums.
  • Prunes.
  • Bananas.
  • Cherries.
  • Kiwi.

People with blood type o should only consume products made with permitted flours, which are

  • Barley flour.
  • Rice flour.
  • Rye flour.

So, if you were a huge fan of English muffins, this diet will not let you enjoy those delicacies. In general, whole-wheat and multigrain bread should be avoided by type o people.

Eggs are a staple in everyone’s kitchen but they are not advised for people with type o individuals, it is suggested to substitute this ingredient with silken tofu. So, knowing all of this, will you go on this diet? Let us know in the comments.
