this article in The New York Times while moseying around the internet yesterday.
It's the first bit of research that makes sense to me into why osteoporosis is relatively rare in Asian countries and prevalent in America. Over the years scientists decided it had to do with the amount of rice or soy in Asian diets. Now it looks like it has more to do with American's skewed beliefs about portions and which side of the food pyramid is the most important.
Now I'd love to see restaurants respond--before anyone applies pressure.
