Corn protein

Q: What did studies of Corn protein find?

Studies of Corn protein measured 2 outcomes; the most studied are muscle protein synthesis (1 study) and insulin (1).

Corn protein has been studied in 2 papers since 2023: 2 trials in people; 1 in the past year. The newest story, Oct 27, 2026: “Corn and milk proteins similarly boost muscle protein production”.

Corn protein decreases insulin in humans.
“A small but significant decrease in insulin levels was observed after the CP intervention when compared to the changes in the BP and WP intervention (P = 0.03 for interaction time x protein treatment).”

Corn and milk proteins similarly boost muscle protein production

Muscle protein production rose 216% from baseline with 20 grams of corn protein, versus 77% with a low-energy placebo without protein.Muscle protein production rose 216% from baseline with 20 grams of corn protein, versus 77% with a low-energy placebo without protein.
