Daily Black Coffee: An Oncologist's Six Health Perks (And Warnings)

An oncologist, Dr. Vartika Vishwani, says she drinks black coffee daily and highlights six benefits—lower risk of death, reduced risk of chronic diseases, liver protection, lower risk of type-2 diabetes, potential cancer risk reduction, and brain health—while cautioning that coffee isn’t for everyone. She recommends moderate intake (roughly 2–4 cups per day, ~300–400 mg caffeine) and consulting a doctor if you have anxiety or heart rhythm disorders, and reminds that coffee cannot replace sleep, exercise, or a healthy diet.
