Every day brings another health headline: Coffee may prevent dementia. Alcohol raises cancer risk. A Mediterranean diet reduces diabetes. A supplement lowers heart disease. A new treatment cuts risk by 30%. But should any of those headlines actually change what you do? In this episode of Live Long and Well, I share five questions I use when reading a new medical study. They can help you separate an interesting finding from something important enough to change your diet, take a supplement, request a test, or start a treatment. The Five Questions 1. Can I trust the evidence? Was this an observational study, a randomized trial, an animal experiment, or something else? 2. How big is the effect—really? A “30% reduction in risk” may sound enormous, but what was the starting risk? We explore why absolute risk can tell a very different story than relative risk. 3. Does it apply to me? Who was studied? Were they people like you? And did researchers actually study the intervention you’re considering? 4. What’s the downside? Benefits are only one side of the decision. Consider side effects, cost, inconvenience, time, anxiety—and the potential downside of doing nothing. 5. What should I do? Sometimes the answer is act now. Sometimes it is discuss it with your physician, watch and wait, or simply keep scrolling. Examples We Explore • Why eating fish and taking a fish-oil capsule are not necessarily the same thing • How mammography and the shingles vaccine illustrate the difference between relative and absolute risk • Why a Mediterranean lifestyle trial was much more than simply “eat more olive oil” • Why bicycle helmets are an easy decision despite a low risk on any single ride • Why aspirin can be highly valuable for one person and inappropriate for another The aspirin example brings all five questions together: the same medication can produce a dramatically different absolute benefit depending on your starting cardiovascular risk.
