Soy Protein Powder and the Bodybuilder…Do They Mix?
Many bodybuilders are sceptical when it comes to soy protein powder, because this supplement had to deal with numerous myths that stopped athletes from taking advantage of it. To learn more about soy protein powder, and the applications for bodybuilders, please read the article below and find out what soy protein really can do for you!
What Are Disadvantages Associated with Soy Protein Powder and Relating to Bodybuilding?
One of the main reasons why bodybuilders are hesitant to use a soy protein powder can be found in some of the disadvantages that some experts claim accompany the use of the supplement. Let us take a closer look at some of these “claimed” disadvantages and what potential problems they could cause.
The low biological value of soy protein tends to be something that stops bodybuilders using a soy protein supplement. Soy is quite low in a specific type of sulphur, which contains the amino acid methionine. It is this amino acid that mainly contributes to muscle growth, but also other important functions such as a good functioning of the immune system and glutathione production.
The presence of anti-nutrients inside soy protein is also concerning for bodybuilders. Anti-nutrients can block the absorption of certain nutrients, which could lead to digestive problems. Soy also contains numerous estrogenic compounds. Some researchers believe that estrogenic compounds increase the amount of estrogen in the body, which could lead to more water retention.
Are the Claimed Disadvantages of Soy Protein Powder True?
We need to mention that there are many myths surrounding the use of soy protein in combination with bodybuilding. However, we can say that the claimed disadvantages are not necessarily true. If you want to know the truth about soy protein and bodybuilding, the following section will dispel and explain some of the myths surrounding this supplement.
First of all, using a soy protein isolate will not expose you to the so-called anti-nutrients found in normal soy. During the manufacturing process of soy protein isolate, the manufacturer removes these anti-nutrients, but also adds some methionine to the mix to ensure there is plenty of the amino acid in your supplement. Because of the additional methionine inside soy protein isolate, bodybuilders can also count on a higher bioavailability than regular soy. Some studies have even shown that the use of the methionine enhanced soy protein isolate can be more effective than most casein supplements!
One thing that could happen when taking soy protein isolate is an increase in LDL cholesterol. However, this must be seen in the right perspective. The increase in LDL cholesterol, caused by the use of soy protein, is derived from the removal of estrogenic compounds. That being said, soy protein has other properties that enable a decrease of LDL cholesterol, more specifically nutrients such as isoflavones, endocrine effects, fibres and saponins. The combination of these factors actually means that the use of soy protein will actually lower cholesterol and recent studies have actually indicated that the nutrients inside soy protein could prevent certain types of cancer.
Another disadvantage that is claimed to accompany the use of a protein supplement is a lower testosterone level in male bodybuilders. However, a recent study with Rhesus monkeys actually disproved this theory. During this study, soy proteins had absolutely no effect on the hormones of these animals. To ensure the accuracy of the study, researchers took readings such as testosterone, DHEAS, sex hormone binding globulin, testicular weight, prostatic weight and more. More even, there was absolutely no difference in hormonal changes for male monkeys subjected to soy protein or egg protein.
Does Soy Protein Provide Specific Benefits for Bodybuilders?
Now we have dispelled the rumours surrounding soy protein supplements, let us take a closer look at the actual benefits soy protein is known for. Based on the dispelled myths, and the benefits accompanying soy protein, you can make the choice whether or not to add soy protein supplements to your current diet.
Bodybuilders with slow metabolisms could benefit greatly from using soy protein supplements. Soy protein isolate has the ability to increase the thyroid output, subsequently delivering more thyroid hormones; this could make your metabolism more effective.
Another aspect of soy protein isolate that could help athletes is the supplement’s ability to increase the amount of a hormone called T4. Even though researchers are still trying to determine the exact cause of T4 increase combined with soy protein isolate, it could be detrimental to the loss of fat. Therefore, athletes looking to lose some fat will find soy protein isolate quite useful.
