specifically why does dr. davis recommend soy?
--------PRETTY POWERFUL REASONS-------------
Soy Protein Powder
Soy protein is a complete protein, i.e., it has all the essential amino acids that humans require. In 1999, after extensive review of the scientific literature, the FDA supported the claim that soy protein lowers cholesterol. A 25-gram serving (three rounded tablespoons) reduces LDL cholesterol by 10% and modestly lowers triglycerides. It also has anti-inflammatory and arterial-relaxing properties. (These benefits are primarily due to the protein component of soy, not the isoflavones.)
Soy protein can be stirred into fruit smoothies and protein shakes, combined with whole grain flours to use in baking or as an egg substitute, or can be added to hot cereals. Traditionally, tofu, tempeh, and textured vegetable protein ("meat substitute") were the among the limited choices to increase soy protein intake. More recently, broader and perhaps more palatable choices have arrived in most markets: soy yogurt, soy nuts, soy chips, soy cheese, soy milk, even low-carb pasta made with soy protein. Soy milk has been around for a number of years but the more recent versions are far more tasty than their bland predecessors.
Soy protein powder can be combined with fiber sources like oat bran, ground flaxseed, raw almonds, beans, pectin from citrus fruit rinds, and psyllium seed (Metamucil) to substantially drop your LDL cholesterol/LDL particle number/apoprotein B. LDL reductions of up to 28% can be obtained when soy protein sources (25 grams per day) are combined with healthy fibers. We commonly see drops of 25-30, sometimes even 50, in LDL using these combinations.
The easiest way to obtain 25 grams of soy protein powder per day is to mix up a protein shake. It makes a tremendously filling breakfast or snack drink that leaves you full and satisfied for hours yet provides all the benefits of soy protein. For instance, combine 2 rounded tablespoons soy protein powder (preferably without excessive sweeteners) with 8-12 oz soy milk in a blender. Add blueberries or other berries and a tablespoon of oat bran or wheat germ. Blend and drink. This high soy protein intake can also be used as an effective weight-loss strategy with most people experiencing a gradual 2-4 lb per month weight loss just by incorporating this practice.
