Blood type diet - Diet & Nutrition Message Board

What do you all think of this diet? I am looking for a nutrition plan that keeps me as healthy as possible. Losing weight is not an issue for me. I am currently on a diet that includes 60-90g protein daily, plenty of vegetables, fruits, and some nuts,butter,cheese, olive oil for fat. I eat no flour or sugar, wheat or hydrogenated oils. I drink only water and caffeine free herbal tea. The purpose of this plan is to treat my chemical imbalance that causes depression. It is working for me. I was curious about the blood-type diet, thought it might also be helpful, but it seems to contradict what I am doing now. Also read some negative reviews about it. Thanks for your input.

As far as I know, there hasn't been any compelling scientific data to back up any of the principles that the Blood Type diet is based on.

Preventing nutritional deficiencies can help with mood imbalances. Amino acids such as tyrosine and tryptophan (in eggs, yogurt, turkey, chicken, fish, peanut butter, nuts, milk) have been found to increase serotonin levels. As well, low levels of B-vitamins and folic acid have also been associated with depression. Avoiding caffeine and refined carbohydrates (like you are doing) can keep serotonin levels from large fluctuations.

That said, I would stick with the diet you are currently on -- what you described sounds healthy, contains a variety of food choices, is easy to carry out, and you say it's working for you.

I find it helpful to keep an eye on the blood type recommendations. I think it is a work in progress (which Dr. D'Adamo does also) and some important factors are not considered, but I my guess is that it will gain more acceptance as time and research goes on. It is such an all-encompassing plan that I don't think definitative "proof" will be coming in any of our lifetimes. Heck, look how long it is taking the experts to get just one matter - fat - straight.

Am I guessing right that you are type A and one of the issues is the amount of protein? You are not alone there . . . many type As question the low recommendations. And in terms of mood, I think a good amount of protein is absolutely necessary. Wheat can also throw off one's mood. So it sounds like you are already doing two major things that I have found helpful. Salmon is "beneficial" for everyone . . . and a good omega-3 supplement (from fish sources, NOT flaxseed or vegetable-based) has proven helpful in a couple of scientific studies.

Thanks for your response. Yes, much of my question has to do with the protein because, as you say, it is essential to helping my mood. There are very few proteins that A's can have, so that is a concern to me. I was curious about this diet because if eating for your blood type has a major affect on your health, I would think that would also include mental health. The book "The Mood Cure" by Julia Ross (this is the plan I follow for my depression) also mentions considering Dr. D'Adamo's ideas but not to take them "too literally". She suggests finding what works best for you and going with that. I also heard another advocate of the blood type diet say to go 80/20 - choose things for your type 80% of the time. That sounds fair to me and would allow me to include some of the foods I like (i.e. oranges, tomatoes) as well as more protein. Thanks again for your feedback.

The blood type diet works because it advocates small portions of nutritious food, no junk food, and exercise. Beyond that, it's all speculation.

For example, the part about Type O people (like myself) tending to have excess stomach acid is true, but can you really extrapolate that into saying that NO Type O person should eat any citrus fruit?
