There is a book by Peter D'Adamo that outlines special diets by blood type. There are differences in diet, for example, people with type O blood should not eat much dairy, but people with type B blood should eat dairy.
Doctor Peter D'adamo specializes in blood type diets. They are specific diets to tailor to the specific needs that arise in individuals while certain blood types. To find out specifics about a diet for blood type O you can go to www.dadamo.com.
Although I personally an unaware of any specific success from diets that are tailored specifically to blood type. There is a diet known as the "the blood-type diet" that claims to have had success with doing just that.
Yes, meat is a good food for blood type O. The theory behind this diet comes from the source of the O blood type. O blood was developed when humans ate mainly meat. Therefore the theory is that you should eat meat, because blood type O is mutated to work with meat better.
It is a myth that people who have blood type O need to adhere to a specific diet in order to not get sick. However, there has not been significant amounts of definitive proof that this is true.
Both A and O blood types benefit from a diet high in deep ocean seafood and avoiding dairy. That is where any similarities end. Type O blood types thrive on a diet containing mostly protein while limiting dairy and grain. Type A types benefit from a mostly vegetarian diet limiting red meat.
Based on the Blood Type Diet, The O blood type is the "ancient man" and oldest blood type. Going by this example, the O blood type should eat foods high in protein, fresh organic vegetables. The O blood type should avoid grains and certain types of beans.
There is not a specific diet for any blood types, this is just a fad and should not be followed. Eat a healthy well balanced diet and you should be okay.
The blood type diet is a fad diet and is not accurate information. As long as you are eating healthy and your diet is well balanced you should be alright with any diet.
Blood type O people are more of omnivorous or they can eat any type of food. Unlike Type A which is a carnivorous and type B which are herbivore. Diet is not problem of blood type O person.
The diet for specific blood types that is generally accepted focuses the difference between the diets on the type of blood (i.e. O, A, or B) rather than the positive or negative charge associated with the blood type. There is no specification for a person with negative type blood.
According to the Eat Right for your Blood Type Diet, it is suggested that people with O blood type eat certain items. These food items include: lean meats, chicken and other game birds, and fish.
The O type diet, requires a person having blood type O, recommends a high protien, low wheat diet. For more information please reference Dr. D'Adamo's book.
