Please try not to laugh if I've got this completely wrong :-)
Are you saying that people can thrive on just about any kind of diet as long as it's organic/natural? If so, would this explain why some people can live on all meat/blubber and some on all veggies (apologies to Metabolic Typing diet)? Also, if our bodies make pretty much everything we need, then exactly what is it we get from our food, just energy?
I've been watching the diet/nutrition scene for years and feel like I'm just running in circles. So I've been looking for common denominators and so far it seems like the whole key to nutrition is to avoid processing. Am I even close?
