New Research Shows Soy Protein Has Two Significant Advantages for Endurance Athletes
Dr. Douglas Kalman of Miami Research Associates reported new peer-reviewed research at the International Society of Sports Nutrition (ISSN) conference in November. Kalman presented "Whey, Casein, Soy: Why Protein Sources are Different: Applications for Endurance Athletes," which highlighted several direct and comparative studies that examined just how, and if, these varied protein sources can be of benefit to the active adult. Kalman said soy protein has at least two significant advantages that need to be known. "While each protein source has its own benefits for metabolism, soy should be better recognized for its quick absorption rates, which means it can enhance muscle and exercise recovery, and its ability to have positive effects whether used in food or powder form," he said.
Kalman's recently peer-reviewed published study, "Effect of protein source and resistance training on body composition and sex hormones," examined the effects of soy and whey in healthy active weightlifting males over a 12-week period. The study found soy protein was just as effective as whey in its ability to help weightlifting males gain muscle. Additional findings noted soy did not have any negative effects on male hormonal levels. The study suggests soy and soy mixed with whey protein had positive effects on male sex hormones.
"Whether you are in a strict exercise regimen or just getting started, soy and other proteins deliver a great source of protein to build muscles," said Dr. Kathy Greaves, Solae Clinical Nutrition Group Lead. "The take home message of Dr. Kalman's presentation is clear: soy protein should be on the athlete's menu plan, and it is a safe, effective dietary protein that has many health-enhancing effects."
Dr. Jose Antonio, the ISSN Conference Chair, said athletes should strongly consider soy protein as a part of their diet.
"The Kalman study clearly delineated that the inclusion of soy protein as part of an athlete's nutritional plan is smart for more than just the obvious heart health reasons," Antonio said. "Now, we can state unequivocally that soy protein can have a strong, positive effect on muscle gains for the athlete when used almost daily and ingested after the workout.

Isoflavones in Soyfoods May Help Asthma Sufferers
Recent research shows that the isoflavones in soyfoods may help asthma sufferers. A study done at the Northwestern University Feinberg School of Medicine in Chicago examined the effects of soy isoflavones in cells and then in patients with asthma. The results suggest that soyfoods may be of benefit to asthma patients. Dr. Ravi Kalhan and his team worked first with cells that are a part of the immune system (human peripheral blood cosinophils), and found they produced much less of a substance (leukotrine) known to cause inflammation. Airway inflammation is a basic characteristic underlying asthma. For more details, click here: (following would be at link)
Kalhan and his colleagues then tested whether the isoflavones would have similar effects in humans and, after four weeks of consuming isoflavone supplements, cells taken from the patients showed one-third less of the inflammatory substance than before taking the isoflavones. The researchers concluded that these findings warrant additional research on isoflavones as a possible means of helping to ameliorate asthma and related diseases.
Isoflavones (phytoestrogens), which are found almost exclusively in soyfoods, are being studied for their benefits in a wide range of areas including coronary heart disease, osteoporosis, cancer and the alleviation of hot flashes, among others. In addition, in 1999, soy protein received a health claim in by the U.S. Food and Drug Administration for its ability to lower cholesterol. Eating whole soyfoods provides protein and the isoflavones.
“Fortunately for today’s health-conscious consumers there’s a wonderful variety of soyfoods out there that can easily add their many benefits, including isoflavones, to today’s meals,” according to Linda Funk, Executive Director of The Soyfoods Council.
“A simple snack of roasted soy nuts, now to be found in almost every supermarket snack and nut section, packs an isoflavone punch, In that same section are soy chips, crisps and other snacks.” Funk continues.
“Popular soymilk now comes in an amazing variety of flavors and convenient packaging in both the dairy case and in aseptic boxes in the grocery section. Consumers can find soyfoods in the produce section (tofu, salad dressings), in the vegetarian or meat section (soy burgers, soy crumbles, sausage, pepperoni and more), in the frozen vegetable section (edamame-shelled and in the pod) and in the frozen dessert section (ice cream, bars and more). “So popular are soyfoods that there’s hardly an area of today’s supermarket that doesn’t have a soy-based item,” Funk reports. “There are new items coming on the market every day so it’s very easy to find a soyfoods item to provide high quality protein, at a reasonable calorie cost and with those important isoflavones.”
