Rice and beans together or just within a day? study tests protein timing

NCT ID NCT07151625

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study looks at whether you need to eat complementary plant proteins—like rice and beans—at the same meal to get all the amino acids your body needs. Researchers will give 40 healthy young and older adults five different diets over nine days each and measure how their bodies build and break down protein. The goal is to see if protein complementation matters at each meal or if getting the right amino acids over a full day is enough.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Diet (whole food provided over 5 periods)

What this could lead to

If successful, this could clarify whether you need to combine plant proteins at every meal or just within a day, helping people plan healthier plant-based diets.

What could go wrong

This is a small, early-stage study with only 40 participants, so results may not apply to everyone. It measures short-term protein metabolism, not long-term health outcomes.
