Blood Group Risks: A, B, AB, O Linked to Diseases, But Lifestyle is Key, Says Research

• Scientific research suggests blood groups A, B, AB, and O can influence susceptibility to certain diseases and infections, though no group is inherently "best" or "weakest."
• Blood Group A: Lower norovirus risk, but higher LDL cholesterol, heart disease, stroke, and some cancers; linked to higher stress.
• Blood Group B: Potential immunity to malaria/smallpox, lower kidney stone risk, but higher risk for heart disease, pancreatic cancer, type 2 diabetes, and high blood pressure.
• Blood Group AB (rarest): Universal recipient, crucial for plasma, but higher risk for inflammation, clotting, heart disease, pancreatic cancer, memory loss, and dementia.
• Blood Group O (most common): Lowest risk for heart attack/stroke, potential COVID-19 protection, but higher susceptibility to norovirus, ulcers, bleeding, and pregnancy complications.

Why It Matters: While blood groups influence health risks, lifestyle, diet, and exercise are far more critical for overall health.
