Why chicken protein contributes more to muscle anabolism than beef protein
Paleo adepts who work out with weights and don't want to renounce their protein shakes have an alternative - protein powders based on beef or chicken meat. Of these two, protein supplements containing chicken protein isolate work best, according to an American study in the Journal of Food Science & Nutrition.
Chicken protein isolate
Products with chicken protein isolate have been on the market for a few years now. For example, supplement manufacturers such as Driven Nutrition [drivennutrition.net] and Barndad Nutrition [barndadnutrition.com] have protein powders for athletes based on ChikPro, [chikpro.com] a product of the American food company International Dehydrated Foods.

International Dehydrated Foods produces raw materials for the food industry based on chicken. The company believes that ChikPro has such a high nutritional value that it is also of interest to producers of sports supplements, sports nutrition and functional foods.
It is nice that a company believes in its product, but if that company can show studies that support this belief, then that is of course even better. And so International Dehydrated Foods funded a human study into the effect of chicken protein isolate on humans.
On 2 different occasions, the researchers gave 22 healthy and physically active men aged 18-45 a shake with 25 grams of protein. One time the shake contained the chicken protein isolate from the generous sponsor, the other time a beef protein isolate from a competitor.
During the first three hours after taking the shake, the researchers analyzed the amount of amino acids in the subjects' blood.
For the total amount of amino acids that appeared in the subjects' blood in the first three hours after ingestion, it did not matter what protein the subjects had used. But as for the essential amino acids, the main amino acids for muscle growth, chicken protein was a significantly better source than beef protein.
Chicken protein was also a better source of arginine, leucine and sulfur-containing amino acids such as methionine and cysteine than beef protein.
More detailed information about what the researchers' findings can be seen here.
The protective effect of the number of steps was slightly greater for cardiovascular death than for cancer death.
The researchers think their study shows that strength athletes, but also older people who want to maintain their muscle mass, may consider exchanging beef protein for chicken protein.
"We conclude that chicken protein is potentially a more effective protein source and is more bioavailable for increasing muscle protein and enhancing recovery as compared to beef protein," they write.
