As a lot of and a lot of people are turning away from meat in favor of plant-based and meat replacement products, scientists are asking a lot of questions on however protein sources take issue from each other. New research looks at whether animal or fungus-derived protein is better for building muscle mass.
Traditionally, some people have considered that animal products are the best source of protein for health. Recently, however, numerous studies have questioned this point of view.
For instance, one 2017 study from the University of Exeter in the United Kingdom suggested that fungus-derived protein (mycoprotein) may be just as good for physical health as animal protein, such as milk protein.
Mycoprotein could be a processed, nutrient-derived form of a strain of the microfungus Fusarium venenatum, which naturally contains a high amount of protein.
For that study, the research team — led by Benjamin Wall, Ph.D. — collaborated with and received funding from Quorn Foods, a company that produces plant-based meat replacement products, and which uses mycoprotein as the protein source in their foods.
Recently, continued their collaboration with Quorn Foods — that distribute their product in some European countries, including the U.K., and in the United States — Wall and colleagues have gone on to search out specifically however mycoprotein compares to animal protein (specifically, milk protein) in terms of contributing to muscle mass growth.
The food company declared for Medical News nowadays that “Quorn Foods give funding for Exeter University’s analysis into mycoprotein and support their commitment to publish the results no matter the findings.”
The researchers have conferred their latest findings at the European College of Sport Science’s 2019 Congress, which this year takes place in Prague, the Czech Republic, between 3–6 July.
Over 120% boost in muscle building rates
As a part of the present analysis, the investigators assessed the digestion of protein in 20 young, healthy male participants. In protein digestion, amino acids — which make up proteins — pass into the bloodstream, thus becoming available for the building of muscle mass.
The researchers evaluated muscle building rate whereas the volunteers were at rest when having participated in a very session of strenuous resistance exercise, and when having consumed either milk protein or mycoprotein.
Wall and team found that the participants who had received milk protein were ready to boost their muscle building rates by up to 60%. However, people who consumed mycoprotein instead increased their muscle building rates by over 120%.
The investigators note that their findings bode well for non-meat eaters, as they show that fungus-derived protein might effectively replace animal protein for muscle building or maintenance.
“These results are very encouraging when we consider the desire of some people to choose non-animal derived sources of protein to support muscle mass maintenance or diversifications with coaching,” says Wall, who is an associate professor of Nutritional Physiology at Exeter.
“Our data show that mycoprotein will stimulate muscles to grow quicker within the hours following exercise compared with a typical animal comparator protein (milk protein) — we glance forward to seeing whether or not these mechanistic findings translate to longer-term coaching studies in numerous populations.”
Other studies conducted by members of Wall’s team have hailed mycoprotein as “a healthy new protein with a low environmental impact,” nevertheless researchers have questioned its safety, pointing to reports of allergic reactions to mycoprotein-containing foods.
Wall and colleagues, however, believe that mycoprotein may be the way forward for a healthful, guilt-free diet.
