Soy: The Super Protein

By Aaron Tabor, M.D.
CEO and Medical Research Director for Revival Soy

CBN.com - Health care professionals and consumers alike are becoming more aware of the potential benefits that adding protein to the diet can provide. Throughout our lives, protein in our bodies is continuously broken down and remade, thus requiring the addition of protein to our diets. High quality proteins provide the best and most efficient way to meet human nutritional needs. Therefore, it is important that the protein added to the diet is of the highest quality possible.

The nutritional quality of soy protein has been studied in depth (1-10). Studies have shown that nitrogen balance, digestibility, and protein utilization are similar between beef and soy proteins (6). Other studies show that soy protein can support nitrogen balance (7, 8) and does provide adequate amounts of the amino acid methionine, which is important for growth and development (9, 10). Recent studies have reported that nitrogen absorption, protein digestibility, biological value, and net utilization of soy protein are similar to milk protein (11-13).

The high digestibility of soy protein, the content and bioavailability of its amino acids, and the nitrogen content make soy protein a high quality protein. Based on protein digestibility calculations, soy protein achieves a score of 1.0, the highest score possible and on par with other high quality proteins like egg whites and milk proteins. Therefore, the addition of soy to the diet is a good way to meet all of your protein nutritional requirements.

Revival Soy makes getting enough soy simple and delicious. With Revival Soy, you can be sure you’re getting enough soy isoflavones in your daily diet—without the soy taste. And you can take comfort in knowing you’re using the #1 doctor-recommended soy protein supplement, backed by clinical studies and many patented benefits.

Just 1 small Revival shake or protein bar gives you the amount of soy isoflavones found in 6 cups of a typical soymilk (160 milligrams). A recent panel of international soy experts recommended up to 160 milligrams of soy isoflavones per day for all of the health benefits of soy.
