Whether soy is good or bad for you is hotly debated. While there’s no question over whether soy is a complete source of protein, some sources claim that soy can be harmful to health. Arguments Against SoyMost notably, there is debate over whether soy has an impact on factors related masculinity. Opponents of soy usually make some or all of the following claims:
The line of reasoning for these arguments is usually as follows: Soybeans contain phytoestrogens. Phytoestrogens are a class of a plant-derived chemicals that mimic certain aspects of estrogen. Most notably, certain phytoestrogens can bind to estrogen receptors in the body, potentially impacting hormonal balance. Soybeans contain a class of phytoestrogens called isoflavones. Specifically, soybeans primarily contain the isoflavones daidzein and genistein, which both have the potential to bind to estrogen receptors in the body. Opponents of soy claim that when the soybean’s phytoestrogen isoflavones bind to estrogen receptors, levels of estrogen rise in the body. In men, high levels of estrogen can lead to infertility, erectile dysfunction, decreased sex drive, and gynecomastia—breast tissue growth. Biochemically, this could theoretically happen. However, such a theory needs scientific testing. Opponents of soy point to the following studies:
This research, at face value, suggests that soy products may negatively impact fertility, testosterone, and other masculine traits. However, as we discuss below, most research on soy does not support the above findings. Arguments in Favor of SoyThose who argue in favor of soy products will point out the flaws in the above studies. Furthermore, they argue that the vast majority of research has not found any correlation between soy consumption and hormonal imbalance. First, there are several issues with the above studies.
While some of these individuals studies may seem to suggest that there is a correlation between soy intake alone and hormonal imbalance, its very easy to point out their flaws. There are a few criteria that need to be met before soy can be seriously considered as a threat to testosterone levels.
The findings thus far that have suggested that soy may decrease testosterone have only been seen in small samples. To control for age, race, diet, weight, physical activity, lifestyle, and thousands of other factors, much larger samples are needed. It may also be that certain soy crops actually have had an impact on testosterone levels. With roughly 90 billion acres of soybean crops grown in the United States alone, any given soy product could be sourced from a wide variety of places.4Soybean Highlights A small sample size could end up consuming a soy product with findings that don’t represent the industry as a whole. In addition to there being a wide varieties of crops, there are a wide varieties of soy preparations. From soy milk to tofu to silken tofu to fermented soy, there are many factors that come into play when considering the processing of these foods. Larger samples with more preparations are needed before coming to broad conclusions on soy in general.
Studies suggesting that soy intake decreases testosterone have widely not been repeated with similar findings. On the other hand, studies finding little to no correlation between soy intake and testosterone have widely been supported by other studies. Back to PhytoestrogensFinally, we return to the original anti-soy argument: that soy contains phytoestrogens, which in turn impact hormonal balance. As discussed above, it is true that soy contains phytoestrogens. However, the body of research has not found that the levels of phytoestrogens found in plant-based foods is enough to notably decrease testosterone. In fact, one meta-analysis of many studies found no correlation between phytoestrogens and feminization.5Soybean isoflavone exposure does not have feminizing effects on men: a critical examination of the clinical evidence. Furthermore, proponents of soy will point out that many plant-based foods other than soy also contain phytoestrogens. Foods high in phytoestrogens:
If someone chooses to abstain from soy because of its phytoestrogen content, then they would logically also want to abstain from the above foods—and many more. Some people simply don’t like soy, and that’s fine. Some people don’t care for it and would rather avoid any potential feminization risk “just to be safe.” Perhaps that’s fine as well. Although the body of research thus far has not found that soy negatively impacts hormonal balance, some people still prefer to stick with soy-free products. That’s why we’ve compiled this list of the best soy-free protein powders. And if you’re fine with soy, these top picks are still excellent choices. How to Take Soy-Free Protein PowderOnce you’ve decided on the best soy-free protein powder for your particular needs, you’ll want to know how much to take and when to take it. Here’s some helpful information on the ideal dosage for your soy-free protein shakes. How Much Soy-Free Protein to TakeWhen to Take Your Soy-Free ProteinFor more information the best dosage and timing for soy-free protein powder, check out our protein powder guide. Brief Protein OverviewNot sure whether protein powders are for you? Here’s a brief overview on protein itself to help you make an informed decision. What Are Proteins?Proteins are made up of amino acids, the building blocks of the entire body. They’re used for all sorts of structures throughout the body, from building muscle tissue to tendons. They also play other important roles in many bodily functions. There are 20 total amino acids. Eight of these, called essential amino acids, cannot be produced by the body and must come from diet. (There 9 essential amino acids for infants.) Complete proteins contain all 8 essential amino acids, and incomplete proteins don’t. Most animal food sources are complete, and most plant food sources are incomplete. There are exceptions to both rules, of course. Benefits of Protein SupplementsThe following information is summarized from our complete protein powder guide. Give it a read for more thorough information. Athletics
Protein supplements help with more than just building up muscle size. Research has demonstrated that drinking a protein shake after each workout can lead to increased strength, performance levels, and one repetition max.26A systematic review, meta-analysis and meta-regression of the effect of protein supplementation on resistance training-induced gains in muscle mass and strength in healthy adults/mfn]26Timing of postexercise protein intake is important for muscle hypertrophy with resistance training in elderly humans27Effects of resistance training and protein plus amino acid supplementation on muscle anabolism, mass, and strength There are three major reasons behind this. First, protein supplements simply help the body produce more muscle tissue, as discussed above. Second, drinking protein after an intense workout helps restore muscle glycogen, a primary energy source. 28Early postexercise muscle glycogen recovery is enhanced with a carbohydrate-protein supplement29Carbohydrate-protein complex increases the rate of muscle glycogen storage after exercise30Postexercise protein-carbohydrate and carbohydrate supplements increase muscle glycogen in men and women31Regulation of Muscle Glycogen Repletion, Muscle Protein Synthesis and Repair Following Exercise And finally, post-workout protein also reduces muscle soreness. Since sore, damaged muscle fiber can’t perform as well as it normally could, reducing soreness results in increased performance and resultant strength gains over time. 32THE EFFECT OF A CARBOHYDRATE AND PROTEIN SUPPLEMENT ON RESISTANCE EXERCISE PERFORMANCE, HORMONAL RESPONSE, AND MUSCLE DAMAGE33Effect of milk-based carbohydrate-protein supplement timing on the attenuation of exercise-induced muscle damage34Acute milk-based protein–CHO supplementation attenuates exercise-induced muscle damage SUMMARY Taking protein supplements can help with gaining muscle mass, boosting performance, and decreasing soreness. Weight LossResearch has demonstrated that drinking protein shakes can help with reducing fat mass while increasing or maintaining muscle mass.35Whey Protein Supplementation Improves Body Composition and Cardiovascular Risk Factors in Overweight and Obese Patients: A Systematic Review and Meta-Analysis36A whey-protein supplement increases fat loss and spares lean muscle in obese subjects: a randomized human clinical study37Effects of protein supplements consumed with meals, versus between meals, on resistance training–induced body composition changes in adults: a systematic review There are a few contributing factors here. The simplest is that protein shakes are filling, and can often replace unhealthy food choices. They can help with both appetite control and responsible dietary choices. But beyond simple meal replacements, protein shakes help increase muscle mass, which in turns helps with burning fat. Even at rest, muscle consumes more calories than fat does. This means that the more muscle tissue you have, the higher your resting metabolism. And the higher your resting metabolism, the easier it is to maintain a calorie deficit and burn fat. SUMMARY Protein supplements can help with losing fat and maintaining calorie-burning muscle mass. SummaryProtein powders can be a great source of nutrition and a great way to hit fitness goals. Luckily, for those who are trying to avoid soy, there are lots of soy-free protein powders on the market. For more information on protein supplementation, see our complete protein powder guide.
