Diet and its history are very interesting. Thanks to dental foresics, we can trace what people ate and when they ate it.

Opinion on diet:

I think people are made to be opportune eaters - eat what you can find and eat it all.

If PETA was concerned about a healthy diet, then they would petition for WIC to include animal protein sources such as Chicken, Fish and Beef to be included in the program. My SIL is neck deep in trying to change this. Many kids are lactose intolerant, mostly minorities, and this has a huge impact on protein/fat intake and subsequent growth and mental development. Meat is the most nutrient dense food as well.

BTW, I love to look at old photos. There are a lot of hints about diet and lifestyles in them.
