For generations, coffee was cast as a quiet threat to human health — a warning embedded in medical culture and reinforced by flawed science. Now, a leading microbiota researcher has placed it among the most beneficial beverages available, with evidence showing that two to four daily cups protect the heart, nourish the gut, and guard the aging mind. The story of coffee is, in part, the story of how medicine learns to revise itself — and how a single habit, practiced with intention, can carry surprising depth.
