Some studies have shown that coffee drinkers live longer, which makes perfect sense given that they have a lower risk of many diseases. The strongest effect is seen for 4-5 cups per day.
A typical 8oz (240 ml) cup of coffee contains:
- Folate: 1% of the RDA.
- Manganese: 3% of the RDA.
- Potassium: 3% of the RDA.
- Magnesium: 2% of the RDA.
- Phosphorus: 1% of the RDA.
- Vitamin B2 (Riboflavin): 11% of the RDA.
- Vitamin B5 (Pantothenic Acid): 6% of the RDA.
- Vitamin B1 (Thiamin): 2% of the RDA.
- Vitamin B3 (Niacin): 2% of the RDA.
Given that coffee drinkers have a lower risk of many common, deadly diseases (and suicide), it makes sense that coffee could help you live longer. There is actually some good evidence to support this. A study published in the New England Journal of Medicine in 2012 looked at the habits of 402,260 individuals between 50 and 71 years of age. In this study, people who drank coffee had a much lower risk of dying over the 12-13 year study period: The sweet spot seems to be at 4-5 cups per day, with men having a 12% reduced risk and women a 16% reduced risk.
