When kids eat more protein relative to other nutrients, their food tends to have fewer calories per gram

Scientific Claim

Dietary protein intake was inversely associated with energy density (MJ/kg) in preschool children, with a leverage strength of -0.50 (95% CI: -0.63, -0.38)

Source Excerpt

“Proportional energy from protein was inversely associated with energy density (MJ/kg) (L = -0.50, 95% CI: -0.63, -0.38).”

Evidence Assessment

Supported

The study used power function analysis showing inverse relationship between protein percentage and energy density. The negative L value indicates that as protein percentage increases, energy density decreases.

How much protein kids eat affects their calorie intake in a complex way that's not just a straight line, and different nutrients interact with each other

Young children's protein intake doesn't change much over time, which makes it possible to study how protein affects body changes later
