Eat Spuds for Muscle Protein

The potato, a perennial favorite deemed nutritionally lackluster, can be a source of high-quality protein that helps to maintain muscle, reports the journal Nutrients. Researchers from Canada’s McMaster University, in Ontario, gave young, healthy women either a placebo or a pudding made with potato protein isolate that doubled the amount of protein the women typically consumed daily. The study found that the potato protein increased the rate at which the women’s muscles produced new protein. “This study provides evidence that the quality of proteins from plants can support muscle,” says Sara Oikawa, lead author of the study.
