Renowned for its energizing boost, coffee ranks among the world's most popular drinks. Yet excessive caffeine can harm health and raise disease risks. Decades of research by scientists have weighed its benefits against potential dangers. The latest evidence recommends capping intake at four cups per day.
A study by American researchers, published Friday, April 21, 2017, in the journal Food and Chemical Toxicology, advises adults to limit caffeine to 400 mg daily—about four cups. Exceeding this heightens risks of cardiovascular, psycho-behavioral, and neurological disorders. This dosage optimizes benefits, helping protect against cancer, diabetes, cirrhosis, high blood sugar, migraines, and memory decline.
The research notes pregnant women should stick to three cups daily. Teens can have up to 2.5 grams. Sensitivity varies: some feel effects after one cup, others need more to shake fatigue. This drives ongoing studies, focusing on highly sensitive individuals and those with specific conditions to fully map coffee's impacts.
