exceeds the body’s ability to neutralize them. Excessive oxidative stress can contribute to cellular damage and is one of many biological processes researchers study in connection with aging.
Scientists have investigated whether genetic and biological differences associated with blood groups could influence oxidative or inflammatory pathways. At present, however, there is not enough evidence to conclude that a particular ABO blood type provides meaningful protection against the cellular effects of aging.
Blood Type and the Immune System
Blood-group antigens can interact with components of the immune and infectious-disease systems. Research
