The Japanese Way of Health

The Japanese live longer than Americans (although only by 4 years on average), despite drinking and smoking heavily. There are all kinds of theories about this. Here's an article saying it's their diet that is the key. They eat fish, lots of veggies, fruits, and rice, and not a lot of red meat or dairy. But of course, there is no way to tell for sure, despite all the numbers. It might be something else entirely.
