The National nstitute of Cancer, the National Institutes of Health and the Feinberg School of Medicine at Northwestern University recently analyzed data on UK coffee consumption BioBank, a long-term study of half a million people in the United Kingdom from 38 to 74 years.
The BioBank is a great sample, while it does not involve control groups, it tracks the behavior and results of more than enough people to establish connections.
The results, published at JAMA Internal Medicine, and summarized in the journal Popular Science, were amazing, not only do coffee drinkers live longer on average than those who do not drink coffee (that was already a well-known phenomenon), but people who drink a lot of coffee tend to live longer than people who drink moderately or sparingly.
Let's be clear on this point: what the research shows is a correlation, not a causal connection. It is possible that people drink more coffee because their lifestyle in general is healthier and, therefore, they live longer. Possible but not likely, however, considering the rest of the other tests that confirm that drinking coffee results in:
20% less risk of cancer
20% less risk of type 2 diabetes
A 30% lower risk of Parkinson's disease.
5% less risk of heart disease.
[b]However, some heads up:
-Pregnant women should avoid caffeinated coffee since babies are not able to metabolize caffeine.
-Coffee additives, specifically sugar and cream, deny most, if not all, of the health benefits of coffee.
-Fortunately, if you buy high quality coffee, and store it correctly and regularly clean your coffee maker, additives are unnecessary. (Coffee is naturally sweet)
