People who drink more than 7 cups of coffee a day are 3 times more likely to see visions or hear voices than those who drink 1 cup, suggests research from UK’s Durham University.
However, a great deal of research shows that “moderate caffeine intake, 400-500mg per day, is safe for the general population and may even confer health benefits”, according to Dr Euan Paul, of the British Coffee Association. Suggested benefits include preventing skin cancer and reducing nerve damage from multiple sclerosis.
