Is coffee healthy? Coffee is one of the most popular drinks in the world, so this article will find out what scientific research says about coffee’s impact on our health and various diseases, including cardiovascular disease and cancer.
Is coffee healthy or does it increase the risk of diseases based on science?
One meta-analysis was conducted, which includes the results of 36 scientific studies and more than 1 million participants.
The analysis concerned the effect of coffee on cardiovascular disease.
This meta-analysis found that moderate coffee consumption (3-5 cups per day) reduces the risk of cardiovascular disease, and high coffee consumption (>6 cups per day) does not increase the risk of cardiovascular disease [1].
The results of several more studies examining mortality from cancer, cardiovascular diseases and other causes of death suggest that regular coffee consumption does not increase the risk of death for both men and women [2] and even reduces the risk of developing these diseases [3].
Also, another study suggests that coffee consumption does not affect the development of stomach cancer [4].
At the same time, it is mentioned that this is provided that the person who consumes coffee does not smoke. If coffee drinkers also do smoke then the risk of developing cancer increases [4].
There is some study though that showed a positive association between coffee consumption and all-cause mortality among men and women younger than 55 years old. The study suggests that younger people avoid heavy coffee consumption (i.e., averaging >4 cups/day) [5].
A controlled cross-over randomized trial shows that even a single cup of caffeinated coffee consumed before bedtime in real-life conditions causes a deterioration in the quality of sleep in caffeine-sensitive subjects [6].
Conclusion
So, is coffee healthy or not? The majority of scientific research shows that coffee does not increase the risk of cancer, cardiovascular disease or death. Moreover, coffee may even reduce the risk of these diseases. There are some exceptions though when coffee can be harmful for our health. So be careful when drinking coffee.
