The Blood Type Diet

Did you know that there are diets for specific blood types? The theory goes that people with certain blood types are more able to digest certain foods than others, so you should consume food that ‘matches’ your blood type. It’s all to do with how your body digests different types lectins.

In essence:

  • People with O group blood should consume foods that are high in animal proteins
  • People with A group blood should be vegetarians
  • People with B group blood should consume dairy
  • People with AB group blood should have a combination vegetarian and dairy diet

Of course, it’s complete and utter rubbish, based on a flawed understanding of science and there’s no evidence that it works, so please don’t change your eating habits based on this blog post. If you want to lose weight and/or improve your health through dieting, speak to your GP about getting a referral to see a dietician, who is more likely to know what they’re talking about.

I have B group blood, but I’m also lactose intolerant, so the diet proposed for me would actually be detrimental for my overall health. I can’t digest large amounts of dairy products without taking supplements.
