Soy Protein

Protein From Soy Beans

1. What is it and where does it come from?

Soy protein is a complete protein that ranks right up there with the best in the Protein Digestibility Corrected Amino Acid Score (PDCAAS). Soy protein is generally very low in or free of fat, cholesterol, and lactose.

Soy protein is approved for those who are lactose intolerant and can be used as a meat substitute. Much more than just an ingredient for a protein shake, Soy protein can be used for cooking instead of flour, producing high protein foods that are extremely low in fat, a bodybuilder’s dream come true! Soy protein is derived exclusively from soy beans.

2. What does it do and what scientific studies give evidence to support this?

Soy protein provides a healthy way to get non-animal protein into your diet. It is great tasting, natural and can have a plethora of healthy effects on the body. It is ideal for high protein/low carb diets! Its valuable constituents include saponins, phytosterols, and isoflavones. This is one of the best things about soy protein! Saponins support healthy immune system function and combine with cholesterol to reduce its absorption into the body through the small intestine. Phytosterols have also been shown to help maintain healthy cholesterol levels. The anabolic isoflavones in soy (genistein and daidzein), not only have exhibited effects as powerful antioxidants but have been shown to exhibit positive health benefits for both men and women.

3. Who needs it and are there any symptoms of deficiency?

As soy is not a required nutrient, it is not associated with deficiency. However, if you don’t take soy, you’ll miss out on the associated benefits. Women can benefit with it the most, although men can experience the positive benefits of soy as well.

4. How much should be taken? Are there any side effects?

Soy may be safely taken in a wide range of doses. Only a very small percentage of people are allergic to soy. Be sure to consult your physician if you’re on any prescription drugs, as soy may have positive or negative interactions with those drugs. Soy contains phytic acid, a compound that may interact with mineral absorption.
