I drink a lot of coffee, about 80 ounces per day. I feel no ill effects and have no stomach discomfort, but my wife says water is better. A kidney specialist basically said, “fluid is fluid” and that as long as I am hydrated, coffee is fine. With studies showing that coffee has antioxidants and reduces certain cancers, what should I do?
People with long memories may recall that in the early 1980s, coffee was linked to an increased risk of pancreatic cancer. However, the study has become a textbook example of poor design, and further studies have suggested that coffee drinking may be associated with lower risk of breast, prostate and oral cancers. I wouldn’t recommend drinking coffee just for this reason, as the effect size, if it really exists, is pretty small.
