A physicist, the demagoguery thing is getting a bit played. You specifically brought up vague references to statistical studies that you imply have some significance. In one, you listed a hazard ratio of 0.69 which would indicate that there is a significant 31% increase in risk. If the initial risk is 0.4% then the 31% increased risk would bring the total risk to 0.524% There is still 99.476% risk by other causes. You grab on to something that appears significant yet is trivial when all risk is compared thinking you have hit on some dire possibility requiring precautionary action. If you are one pound over weight, there is greater risk. If you use strenuous exercise to reduce weight, there is even greater risk. You need to place things in perspective as I mentioned, herbal tea consumption does have a statistically significant risk involved based on your standards.
This is the same linear no threshold model standard used by the risk analysis impaired to over regulate nuclear, food preservatives and if Ralph Nadar has his way, Ajax cleanser (because it contains… silica!).
