New research by two big studies suggest that coffee, even de-caf, is good for your health
For coffee-addicts worldwide, two big studies have just revealed that being a regular coffee drinker may reduce the risk of heart disease, diabetes or even cancer.
The two large studies published in the Annals of Internal Medicine discovered that the more coffee an individual drank, the lower that person’s risk of early death. The results were consistent across 700,000 coffee-drinkers from a variety of racial and ethnic backgrounds.
Thus far, science has suggested coffee is not bad for you – but the studies generally involved much fewer people and usually only individuals of European Descent.
Researchers said they “found no indication that he associations varied by race/ethnicity,” and the link between increased coffee drinking and higher longevity was consistent and significant in all groups except for Native Hawaiians.
Researchers cautioned that the only reason the results weren’t as significant with Native Hawaiians because there were not enough of them available in the study.
However, both American and European researchers found no evidence that coffee was linked to improved health in only certain countries.
Biological link between coffee and good health
The reason that compounds in coffee may reduce risk of premature death is because of what they are.
Polyphenols act as antioxidants, and genes related to caffeine metabolism influence things like cholesterol and blood pressure.
Coffee-drinking has also been linked in previous studies to improving liver function, sensitivity to insulin and inflammation.
The results are still too “premature” to recommend coffee to “reduce mortality or prevent chronic disease.”
However, the results do confirm that there is nothing dangerous about being a coffee-drinker, with the average drinker consuming up to five cups a day.
An estimated 2.25 billion cups of coffee are consumed around the world every day.
