Fabulous article on food scares. A small piece:

I believe in moderation in everything — including moderation. The risk of cancer supposedly increases if you eat more than one 8-ounce fillet of farm-raised salmon a month, for example. But how much is that increased risk? What does it really mean? As I understand the statistics from the Environmental Protection Agency, the risk goes up by one in 100,000 if you eat that 8-ounce farmed salmon fillet once a month for 70 years. By contrast, the risk of getting a fatal heart attack is about one in 400.
