The Facts: Behind The Blood Type Diet

What's your type? Knowing your blood type is important for a variety of reasons, but for this nutritional diet, knowing your type is crucial. The whole diet is based on your blood type and is focused on providing what your blood type most needs. Learn more about the diet, the doctor behind it, what you should be eating for your blood type, and most importantly - is this diet safe, and does it work?


The Blood Type Diet is a diet promoted by Dr. Peter D'Adamo. In his book Eat Right For Your Type, he claims that blood type is the most important factor in determining a healthy diet. He has, in turn, developed a diet for each specific blood type, whether it be one that has been around for thousands of years or one that is fairly new and uncommon.
According to D'Adamo, Blood group O is the earliest human blood group. The diet for this blood group is based on proteins, including meat, so this is not a diet a vegetarian can partake in. Based on the fact that this is considered the oldest blood type group, the diet focuses on meats, nuts, berries, fish and vegetables, much like the Caveman Diet. Options for this diet include green veggies such as spinach, broccoli and kelp.

Blood group A
is called 'the cultivator' by D'Adamo. This diet is vegetarian-friendly and focuses on a diet of vegetables and grains and soy products.

Blood group B
supposedly includes a strong digestive system and can therefore function very well with a diet based on dairy such as eggs while avoiding wheat products, nuts and seeds. Only one person in about ten has this particular blood type.

The Blood group known as AB is the 'newest' (and rarest) of the groups and should focus on a mixed diet of meat, seafood, greens and grains.
Like many diets, this one is met with some controversy. Many experts say that the notion of a blood type matching up to a specific diet is utter nonsense. They also warn, as they do with many diet fads, that this diet neglects to give a reason for omitting certain nutrients and can be limiting in the types of foods it allows.


Losing weight with this diet is possible, and the reason is obvious: so much of it cuts down on the breads, a source of carbs. The 'O' plan doesn't focus on dairy, which we know helps keep bones healthy. At the end of the day, this diet may be a quick-fix for someone who wants to lose a few pounds, but it is not a well-balanced diet. Many doctors say blood type doesn't matter when it comes to dieting.

With any diet plan, please consult a doctor before attempting.
