In plain English

This claim suggests that every human being has the exact same ideal diet and macronutrient needs, with no personal differences. In other words, there is one perfect nutritional balance that works equally well for everyone, regardless of age, genetics, or lifestyle.

See the scientific wording

Optimal dietary composition is a conserved biological trait within a species, meaning individual variations in optimal macronutrient requirements do not exist within Homo sapiens sapiens.
