The Claim

Total nitrogen intake, rather than essential amino acid content alone, is the primary limiting factor for nitrogen balance in young men consuming the 1973 FAO/WHO egg protein recommendation of 0.57 g/kg/day.

Source: Human protein requirements: interrelationships between energy intake and nitrogen balance in young men consuming the 1973 FAO/WHO safe level of egg protein, with added non-essential amino acids.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

How it works
1 study reviewed
In plain English

When young men eat eggs as recommended, it’s not just the good proteins that matter—it’s the total amount of nitrogen they get from all the protein that determines if their body keeps or loses muscle.

Total nitrogen intake, rather than essential amino acid content alone, may be the primary limiting factor for nitrogen balance in young men consuming the 1973 FAO/WHO egg protein recommendation of 0.57 g/kg/day.

What the research says

1 study
  1. Study: Human protein requirements: interrelationships between energy intake and nitrogen balance in young men consuming the 1973 FAO/WHO safe level of egg protein, with added non-essential amino acids.

    Scientists gave young men a low-protein diet and then added extra non-essential amino acids to increase total nitrogen. They found the men stayed healthier with less energy when they got more total nitrogen, suggesting it’s the overall amount of nitrogen, not just the good amino acids, that matters most.
