Hey guys, I need to write an English paper this week, and the topic is to find a paradigm shift and analyze it in any type of field possible. I find nutrition very intriguing, and I was wondering if anyone knew of any historical massive changes in nutrition? Like about certain discoveries, such as antioxidants, protein, new food groups, or anything of the like. I know quite a bit about current nutrition, but I don't know what people used to think maybe a hundred years ago or anything. Anyone care to help me out and step inside of the mind of a nutritional person from the 1800's or 1900's?
