Being healthy is usually considered to be a mix of regular exercise and a nutritious diet. The experts at the Center for Disease Control and Prevention have recommended a mix of fruits, vegetables, lean meat, and poultry as a healthy diet. For a short duration, an individual’s blood type was considered to be a base for their nutritional needs. However, this assumption was swiftly debunked due to the paucity of scientific evidence in 2013 after a review published in The American Journal of Clinical Nutrition. After observing several cardiometabolic factors, the findings of a 2014 study also did not find supporting evidence for diets tailored to blood types.
However, individuals who followed the Type-A diet, which involves a major portion of grains, vegetables, and fruits, gained a lower BMI, lower waist circumference along with dropped blood pressure, cholesterol, and body fat among many other positive benefits. Also, these positive benefits did not depend on blood type. Despite rare evidence to support the diet based on blood types, some individuals believe that consuming food according to one’s blood type can reduce the chance of suffering from diseases. The interest in the blood type diet could be due to the health benefits offered by a plant-based diet. These diets also help to minimize the risk of heart diseases and obesity among others.
A low-fat vegan diet was observed to have aided in reducing insulin resistance and bolster metabolic function through a recent study in the JAMA Network Open. Taking these results as a base, researchers from the Physicians Committee for Responsible Medicine re-evaluated previous observations to ascertain if blood types played a role. This was done on the participants from an intervention group for 16 weeks. After that, the researchers created two groups for their observations, it was noted that there were no noteworthy differences in the average body weight among all the blood type groups. There was no difference in the cholesterol levels of either group in terms of average cholesterol levels. Due to several drawbacks such as representation, the number of participants within the B and AB blood groups, a majority of health-conscious participants who consumed a low-fat vegan diet, it might have been atypical of the general population.
As a summarization, the researchers declared that the gathered data was indicating a rarity in terms of strong evidence for the blood type-based diet. Also, the A blood type had a positive response to higher consumption of vegetables, grains, and fruits as well as any other blood types that exist.
