The podcast’s third-year anniversary celebration turns out to be the perfect time to discuss coffee. Does it prevent disease… or cause disease? Why are pregnant women told to avoid excessive caffeine consumption if it’s a wonder drug? And, if it’s a drug, is it addictive? We discuss its purported links to miscarriages, birth defects, fertility, cardiac risk, blood pressure, cancer, migraine, and Parkinson’s disease. Plus: why complications are not the same as medical error, and the really bad study that led to the pronouncement that cell phone exposure was associated with increased risk of miscarriages.
