The B Negative Blood Type Diet is a dietary regimen that claims to improve health based on one’s B-blood type. However, scientific evidence does not support the effectiveness of blood-type diets. Leigh A. Frame, a Ph.D. holder in the field, tweeted that the Blood Type Diet is “not based in science” and is “overly restrictive and impractical.”
She emphasizes the lack of research to support or refute the claims made by proponents of this diet. Leigh A. Frame shared her analysis on Twitter, stating, “Blood Type Diet not based on science: Many claims without #research to support (or refute) them.”
Speaking of research, a systematic review published in the American Journal of Clinical Nutrition in July 2013, conducted by Leila Cusack and colleagues from the Belgian Red Cross-Flanders, found no evidence to support the health benefits of blood type diets. Out of 1415 screened references, only one article was considered eligible, and it did not directly answer the question about the effectiveness of blood type diets. The study concluded that “No evidence currently exists to validate the purported health benefits of blood type diets.”
Despite the buzz, there’s no scientific backing for the B Negative Blood Type Diet. So, what to do? This article breaks down everything there is to know about the negative Blood Type Diet.

According to proponents of this diet, people with B-negative blood type are believed to benefit from a diverse diet that includes a balance of various food groups.
Scientific evidence supporting the effectiveness of this diet is currently limited, with no specific studies conducted on the B-negative blood type diet. However, some studies have explored the relationship between blood type and certain health conditions or dietary patterns, such as the ABO blood group system and cardiovascular disease risk. These studies have shown mixed results and more research is needed to draw definitive conclusions.
How does the B Negative Blood Type Diet work?
The B Negative Blood Type Diet proposes that individuals with B Negative blood type have specific dietary requirements to support their optimal health and prevent diseases.
