There may be good news for coffee lovers. Drinking three cups a day could help you live longer. This is according to researchers from the International Agency for Research on Cancer and Imperial College London. They looked at data on half a million people over the age of 35. They suggest that drinking coffee means coffee drinkers have an 8-18% lower risk of early death or health problems than non-coffee drinkers.

Not all experts agree. Some say the health benefits of coffee could be because coffee drinkers have more money and so are healthier. Coffee drinkers may socialize more and this could help people to live longer. The research does not prove that drinking coffee has health benefits. The researchers warned against drinking too much coffee. The safe daily amount of caffeine is around 400 mg. More than this increases the risk of panic attacks and heart problems.
