The truth about protein absorption: What happens when you eat a lot at once

Questions about how much protein the human body can absorb in a single meal have prompted renewed discussion about nutrition and digestion, according to The Washington Post.

In a report published on September 10, the newspaper examines the science behind the widely repeated claim that the body can absorb only a fixed amount of protein at one time.

The report explains that absorption and utilisation are different processes. The digestive system can absorb protein and its amino acids, while how those nutrients are subsequently used by the body depends on factors including the type of protein, overall diet and the body’s needs.

The findings challenge simplistic rules about a strict protein limit per meal, suggesting that protein intake should be considered within the context of a person’s overall nutritional needs rather than a single meal.
