Around 85% of the population is Rh-positive, carrying the Rh protein on their red blood cells.

Some individuals experience more mosquito bites than others, and it is natural to question the role of biological factors, such as blood type. This is influenced by chemical cues emitted by the human body, with blood type being one element in a complex formula of attraction.

In 2013, a systematic review published in the *American Journal of Clinical Nutrition* found no scientific evidence to validate the health benefits of blood type diets, and this includes claims about which blood type needs carbs. While the idea of a diet tailored to your blood type is appealing, medical experts and scientific research do not support it as an effective or necessary approach to nutrition. The truth is, everyone needs carbohydrates, and your blood type is not a reliable indicator for your dietary needs.

According to one 2016 study of blood donors, individuals with blood type B had the lowest serum ferritin levels, a key indicator of the body's iron stores.
