Mycoprotein and Muscle Protein Synthetic Response


Dietary protein is vital for the preservation of health and optimal adaptation to training. However, traditional animal proteins come with a number of economic, environmental, and ethical issues. Accordingly, there is a need to develop an understanding of the utility of more sustainable non-animal derived dietary proteins to support our nutrition. Mycoprotein, produced by Quorn Foods™, has recently been shown to stimulate a greater anabolic response within skeletal muscle compared with milk protein, suggesting its utility within sports nutrition. However, it is unclear what accounted for the greater anabolic response of mycoprotein. One explanation could be the non-protein nutrients contained within mycoprotein (e.g. fibre, carbohydrate, fat or micronutrients).

Therefore, the present study will compare the muscle anabolic response between mycoprotein (MYC) as a whole food and the protein isolated from mycoprotein (PIM).
