Eating For Your Blood Type

Hi y'all!
I was asked about "the Blood Type Diet" yesterday by a friend. I have heard about this diet before, but haven't read into it. I decided to take some time to look into the Blood Type Diet and write a simplified explanation of it here.
This diet was created by Peter J. D'Adamo, a naturopath. He believes that the foods we eat have chemical reactions with our blood. The idea behind this diet is that different foods with react with your blood type, and if you eat a diet "for your blood type" your body will digest the foods more efficiently. More benefits Mr D'Adamo believes will happen as a result of his diet are weight loss, increased energy, and disease prevention.

Here's what D'Adamo recommends for each type: (Provided via WebMD)

"Type O blood: A high-protein diet heavy on lean meat, poultry, fish, and vegetables, and light on grains, beans, and dairy. D'Adamo also recommends various supplements to help with tummy troubles and other issues he says people with type O tend to have.

Type A blood: A meat-free diet based on fruits and vegetables, beans and legumes, and whole grains -- ideally, organic and fresh, because D'Adamo says people with type A blood have a sensitive immune system.

Type B blood: Avoid corn, wheat, buckwheat, lentils, tomatoes, peanuts, and sesame seeds.  Chicken is also problematic, D'Adamo says. He encourages eating green vegetables, eggs, certain meats, and low-fat dairy.

Type AB blood: Foods to focus on include tofu, seafood, dairy, and green vegetables. He says people with type AB blood tend to have low stomach acid. Avoid caffeine, alcohol, and smoked or cured meats."

There hasn't been much research on the actual effectiveness of this diet in terms of weight loss. One study (The only one published anyhow) has evaluated the Blood Type Diet. Their results found that people with certain blood types received a cholesterol-lowering benefit from eating a low-fat diet. However their research it didn't support that the Blood Type Diet works for weight loss.

KRegan's thoughts:

Holy cow! I've been eating according to my blood type for a while now! My blood is type O and I eat a lot of proteins and vegetables and I watch my grain in-take. I realized several months back that I am sensitive to lactose so I have pretty much eliminated it from my diet. Oh, and yes I have suffered from awful tummy-troubles for years. Through dietary changes like eliminating dairy, I have been to prevent my stomach problems.

In my opinion, the Blood Type Diet has me pegged. Right. On. The. Nose. There might be something to the Blood Type Diet after all.

Im curious though, has anyone else been eating according to their blood type? Anyone willing to try it out for 2 weeks to see if it works for them?

For an additional article about this, Men's Fitness magazine has a great article here. (According to them I'm a leader and should avoid dairy. Well duh Men's Fitness. LOL)
