People who use the blood type diet believe that blood types influences how the body handles food. Blood type is said to be a part of a person's biological descendancy or heritage. Proponents believe that some blood types are more prone to certain diseases or conditions. They suggest that consuming a special diet based on blood type can decrease the risk of these conditions.

Blood typing proponents pay particular attention to dietary lectins. They suggest that people with certain blood types could respond adversely to lectins, resulting in disturbed metabolism, inflammation, and weight gain.

Blood type A people are said to be "slow oxidizers." They are able to consume more carbohydrate than others, but should avoid red meat and dairy because lectins in these foods could be problematic.

Blood type B people are said to be "fast oxidizers." They are supposed to avoid lectins in corn and wheat products.

Blood type AB people are "slow oxidizers," but unlike blood type A people, they can sometimes tolerate dairy problems, without adverse effects.

Blood type O people are "fast oxidizers." The can tolerate red meat, but should consume less carbohydrate and should avoid wheat. Lectins from wheat in this group can cause high insulin levels and lead to metabolic syndrome.

There is no reliable scientific information available about blood typing or therapies based on blood typing for reducing or preventing medical conditions.
