There has been great debate over the years about the pros and cons of drinking coffee. The confusion is justified, as one study will report on the negative affects while the next will highlight its beneficial attributes. So here we go again, but this time, the focus is on whether or not the compounds found in coffee can help you live longer.
In a 2017 study published by the International Agency for Research on Cancer and the Imperial College London, researchers surveyed 520,000 people from ten European countries and concluded that drinking coffee does appear to promote a longer lifespan. According to the study, other significant health benefits associated with coffee consumption include lower mortality rates from liver and digestive disease in both men and women; decreased mortality from cancer, circulatory disease, and cerebrovascular disease (stroke) in women; and a reduced suicide rate for men. Coffee consumption also lowers inflammatory markers and other negative biomarkers in the blood, giving us some insight on how the compounds in coffee may promote longevity.
The other study, this one funded by the National Cancer Institute, included a diverse set of subjects, as the survey included more than 185,000 adults from various ethnic backgrounds. The authors of this study also concluded a link between coffee consumption and living longer.
Regarding the dosage of coffee required to achieve the most benefits, the European study found the more coffee consumed, the better. They observed that participants who consumed three cups a day had better protection against all-cause death than those consuming less, especially when compared with the non-coffee drinkers. Also, because the researchers surveyed people from many different parts of Europe, it didn’t appear to matter what brand of coffee the particpants consumed, how it was prepared, or the serving style.
The United States-based study echoed many of the same findings as it reported that individuals consuming two to four cups a day had an 18% lower risk of early death in comparison with the non-coffee drinkers, regardless of the ethnicity, coffee type, or preparation style.
Not to burst your bubble about the health benefits of coffee, but moderation is still recommended regarding your daily indulgence. Nutritionists also warn that adding heavy cream and sugar may nullify many of the health benefits of black coffee plus add unnecessary calories to your diet.
Look for future research to focus on determining which compounds found in coffee provide the most benefit and if they can be consumed as a supplement for people who are not coffee drinkers.
