What scientific results are you googling exactly? Everything I can find shows a strong consensus that coffee has positive effects across the board. This seems like a good summary: https://www.nytimes.com/2015/05/12/upshot/more-consensus-on-coffees-benefits-than-you-might-think.html https://www.nytimes.com/2015/05/12/upshot/more-consensus-on-... Highlight from that article: >There have been two meta-analyses published within the last year or so. The first reviewed 20 studies, including almost a million people, and the second included 17 studies containing more than a million people. Both found that drinking coffee was associated with a significantly reduced chance of death. I can’t think of any other product that has this much positive epidemiologic evidence going for it. I don't understand how you can claim coffee is bad for your heart in good faith if you have read _any_ of the research... for example, this meta-analysis of 36 studies: https://www.ncbi.nlm.nih.gov/pubmed/24201300 https://www.ncbi.nlm.nih.gov/pubmed/24201300 > A nonlinear association between coffee consumption and CVD risk was observed in this meta-analysis. Moderate coffee consumption was inversely significantly associated with CVD risk, with the lowest CVD risk at 3 to 5 cups per day, and heavy coffee consumption was not associated with elevated CVD risk. I think any doctor worth their salt would tell you that there is a strong scientific consensus that drinking coffee is not only completely safe, but it has preventative effects towards cancer, cardiovascular disease, Parkinson's, and Type-2 diabetes. Here's a bonus review of 112 meta-analyses: http://www.annualreviews.org/doi/abs/10.1146/annurev-nutr-071816-064941 http://www.annualreviews.org/doi/abs/10.1146/annurev-nutr-07... > Of the 59 unique outcomes examined in the selected 112 meta-analyses of observational studies, coffee was associated with a probable decreased risk of breast, colorectal, colon, endometrial, and prostate cancers; cardiovascular disease and mortality; Parkinson's disease; and type-2 diabetes.
