The Claim

The 1973 FAO/WHO safe level of egg protein intake (0.57 g/kg/day) may be inadequate for long-term maintenance of nitrogen balance in healthy young men, as observed in this study at 0.59 g/kg/day.

In plain English

A long-standing guideline says people should eat 0.57 grams of egg protein per kilogram of body weight each day, but this study suggests that might not be enough to keep healthy young men’s bodies in balance — they might need a little more, like 0.59 grams.

  1. Study: Human protein requirements: a long-term metabolic nitrogen balance study in young men to evaulate the 1973 FAO/WHO safe level of egg protein intake.

    This study found that eating the amount of egg protein recommended in 1973 wasn't enough to keep healthy young men's bodies in good shape over time—they started losing important proteins. When they ate more protein, their bodies got better, proving the old recommendation was too low.
