(Journal of the International Society of Sports Nutrition) recently published a scientific paper in the Journal of the International Society for Sports Nutrition on the relationship between exercise and eating chicken feathers.
This was done by Emma Crum and Yanita McLeay, Ph.D. students from the School of physical Education and Nutrition at Macy’s University, under the guidance of their mentors, Professor Steve Stannard and Dr. Matthew Barnes.
Are you kidding me? Chicken feathers, not chicken? Are you crazy? ! Don’t worry, take your time.
The conclusion of the study is that for those who want to stay lean, “eating chicken feathers is a better way to supplement the biological potential of protein than eating chicken.”
In fact, 90% of the total weight of poultry feathers is made up of animal keratin, which is chemically rich in mercaptan. Usually people don’t eat chicken feathers (even though it’s so protein-rich, no one ever thought about how to eat chicken feathers) because we can’t digest them.
In the study, Professor Stannard said, we first need to use a process called acid hydrolysis to improve the water solubility of chicken feathers. The chicken feather mixture is then cooled and alkali added to elevate the solution pH, to form a neutral pH edible protein mixture.
Finally, the solution is dried and ground, and flavoring is added to form a “high-grade protein powder.” (now you should see how the so-called high-grade protein powder is made. ).
In these experiments, the researchers made two different flavors of “protein bars” from “high-grade protein powder” (the energy bars might have been made from chicken feathers, not chicken! ), or mix powdered “high-grade protein powder” with water to make an energy drink.
To compare and test their effectiveness, the researchers recruited 15 male cyclists aged between 18 and 50 who received intensive training.
They were given four weeks of “high-protein powder” as an energy supplement, while the control group was given a dairy supplement of the same weight. Participants were then monitored for casein in their bodies, changes in blood and cardiopulmonary respiratory function, and effects on the circulatory system.
Professor Stannard said that although there were no significant differences in the overall weight and percentage of body fat, an interesting phenomenon was found.
Test data showed that although “feather keratin” can not be used as an auxiliary means to improve the body function, but after four weeks of exercise training, the human body weight (muscle) proportion increased significantly. Dairy supplements did not have the same effect in the control group.
Professor Steinard said, “there was no change in cycling performance, but participants had a good absorption and tolerance for chicken feather keratin.” Therefore, they may well be used as advanced protein supplements to improve muscle athletes, or to give older people to enhance their lean weight type.
“it is clear that soluble keratin supplements an individual’s need for protein in physical activity and is beneficial to circulatory function,” says the Journal of the International Society for Sport Nutrition.
