Thanks for the responses although I am kind of confused by them as well. I am asking because IP products have a protein score of 100; the protein is as bioavailable as that of egg whites. All protein products can be scored and compared using that scale.
Nowhere have I seen protein scores for alternative products, although many time the ingredients and stats are very close. This could mean they don't compare. It could mean the question hasn't been asked before by the diet community. I suppose I could contact the companies and ask.
In theory I could sub egg whites for the packets, but the taste, variety, and nutritional composition wouldn't be the same. I am not under the impression that the packets are better than real food, but they do serve a purpose.
