A 2017 review of 201 coffee studies and 17 clinical trials, published in The BMJ, found coffee was “associated with a lower risk of several cancers, including prostate, endometrial, skin and liver cancer, as well as type 2 diabetes, gallstones, and gout.” Above that, the researchers discovered positive effects on brain health: Coffee consumption was linked to a lower risk of Parkinson’s disease, depression, and Alzheimer’s disease.

However, this is a good moment to say that whatever the studies say about this food or that lowering the risk of cancer, cancer rates have exploded in recent decades no matter how much coffee people drink. Humility is not found in numbers, medical science or medical practice. That is why we need to take everything and put it together to develop the best picture we can for our health and for our children.
