Guest guest Posted February 17, 2006 Report Share Posted February 17, 2006 Rodney, Gelatin is produced by boiling collagen for a long time, so it is an ideal protein source for maintaining bone structure. This is why many preparations used to treat arthritis (Glucosamine and Chondroitin Sulfate) also have gelatin. The amount of protein needed is in the tablespoon range, rather than the capsule range, and many off-the-shelf remedies do not provide sufficient protein. I have a table comparing the amino acid compositions of various protein sources at the bottom of one of my web pages. The percentages for whey, casein, soy and yeast are averages of several products sold commercially as supplements for bodybuilding, rather than just the data from the USDA National Nutrient Database. http://www.scientificpsychic.com/fitness/aminoacids1.html The Institute of Medicine has an informative chapter on protein metabolism (link below). You will notice that the protein RDA is 0.8 grams per Kilogram of body weight. This is only 0.36 grams per pound of body weight, which is about 54 grams for a 150 pound person. This is too little, as Walford mentions in BT120YD (pp. 231-232).
