More Consensus on Coffee’s Benefits Than You Might Think – NYTimes.com

2015-05-12

Is coffee associated with the risk of death from all causes? There have been two meta-analyses published within the last year or so. The first reviewed 20 studies, including almost a million people, and the second included 17 studies containing more than a million people. Both found that drinking coffee was associated with a significantly reduced chance of death. I can’t think of any other product that has this much positive epidemiologic evidence going for it.

Despite years of bad press, coffee persists as the most popular beverage for adults.  Frequently it is prepared with large quantities of sugar, cream, vanilla, and other flavorings which raise the calorie count from a negligible five calories per serving to 500=750 calories in as much as 24 ounces of liquid.  Starbucks, for example, with a white chocolate macchiato in venti size, has 580 calories.  These high calorie beverages are obviously not good for the health.  But plain coffee has many advantages.

A number of meta-analyses of very large groups of people have shown reduced risk for stroke, cardiovascular disease, heart failure, Parkinsonism, liver and breast cancer, cirrhosis, type 2 diabetes, and improved response to treatment for hepatitis C.

None of these studies are of the double-blind, randomized, case-control or crossover variety that can provide ironclad evidence of causation, but the association of coffee with reduced mortality is so strong that there must be some logical explanation, for example: drinking coffee must be good for you.

There are of course some people who do not react well to coffee, in some cases because of a missing enzyme for the metabolism of caffeine.  There are also those who do not like the taste.  For the rest, there is no harm and possibly considerable benefit from drinking a few cups of coffee (without sugar) each day.
