Does A Blood Type Diet Actually Make You Healthier?

It seems like every day there is a new diet making its way through the headlines. There’s a new superfood that’s going to save your life or there’s this new no-carb diet that’s just to die for. However, most of these diets are just a fad and something that’s not really going to help you out in the long-run. You’re much better off listening to your doctor about the right foods to eat for your health than going for one of these fad diets.


However, there is one interesting diet that you might have heard a lot about in recent years. And that’s the blood type diet. This is the diet that proposes every blood type has certain foods that are better for you to eat. If you are blood type O, then there are certain foods you should be getting into your system. If you are blood type B+, then there are different foods. Continue reading to delve more into this topic and determine whether or not this is a diet that actually helps make you healthy.

What is it?

First of all, we’re going to talk a bit about what this diet actually is and what it consists of doing. This diet was brought about in 1996, so it’s not really a new phenomenon. The doctor who developed this diet says that there are certain genetic traits in our blood that are exactly how are ancestors ate back in the day. And if we were to eat those same foods that are ancestors did, then we are going to be much healthier than otherwise. Below are the blood types and what you should eat based on his research:

  • Blood Type A – If you have this blood type, then you’re going to eat a largely vegetarian diet. You should be getting iron-rich vegetables into your diet and stay away from red meat.
  • Blood Type B – You are not going to be able to eat chicken or pork, but you can eat other meats and all plants. Some dairy is also fine to add to your diet. However, you’re going to want to watch out for lentils and wheat.
  • Blood Type AB – Think about this one as a mix between blood type A and blood type B, which does make sense if you think about it. You can’t eat beef or chicken, but you can eat certain seafoods and beans.
  • Blood Type O – This last blood type is going to be focused on a paleo diet, full of meat and great veggies/fruits.

What are lectins?

One of the most important parts of this diet are a protein called lectins. These are basically molecules that bind together sugar particles. It’s been claimed that if you eat too much of lectins, then this can cause the clotting of blood cells in your body. And if you adopt one of these blood type diets, then this is going to be the perfect solution for you.

However, when you look at scientific theory, there is absolutely no evidence to suggest that taking down on these lectins helps out your health. Moreover, there is no evidence to suggest that this blood type diet is going to work – most research shows there is no connection whatsoever between your diet and your blood type. So, when you look at the science, you see that this diet is just another fad that’s not going to dramatically change your life. However, if you did implement some of these changes into your diet and give up processed foods, then you would definitely see some change in your overall health.

There you have it! The blood type diet is a pretty healthy diet to start up, but don’t expect some magical change now that you are eating foods that are supposedly good for your blood type.
