There is potentially good news coffee lovers. Drinking three or more cups coffee a day may help people live longer. This is according to a 16-year-long study the International Agency Research on Cancer and Imperial College London. Researchers looked health data over half a million people the age of 35 from 10 European countries. They suggest that drinking more coffee is linked to a lower risk death, particularly heart diseases. This study showed that people who had a daily minimum three cups of coffee were 8-18% less likely to die health problems than non-coffee drinkers. Researchers said coffee drinkers had better liver function and a stronger immune system.
Not all experts agree the research findings. Health experts suggest that the health benefits drinking coffee could be because coffee drinkers may have more money and therefore live a healthier lifestyle. They also say that because drinking coffee can be a social activity, coffee drinkers may socialize more and this may increase wellbeing and help us live longer. They say the research does not prove that drinking coffee has concrete health benefits. Researchers also caution drinking too much coffee. The upper level safe caffeine intake is 400 mg. More than this increases the risk suffering panic attacks, heart problems, and insomnia.
