With all the media attention on cholesterol, consumers often lose sight of the fact that eggs are a nutrient rich, affordable contributor to a healthy diet. Not only do eggs contain the highest quality source of protein available but they also contain almost every essential vitamin and mineral needed by humans. In fact, egg protein is of such high quality that it is used as the standard by which other proteins are compared. Eggs have a biological value (efficacy with which protein is used for growth) of 93.7%. Comparable values are 84.5% for milk, 76% for fish, and 74.3% for beef. Eggs really are the best protein money can buy, and all of those other valuable vitamins and minerals too. One of the major protein ingredients in PowerButter is egg white, which contains no cholesterol.
