The average human body contains 1.8kg of Nitrogen, of which 50-60% is sourced from foods directly enriched by petrochemical fertilisers (which supply 50-90% of the eventual Nitrogen content as most global topsoil is nitrogen depleted).
A conservative calculation tells us that 0.5kg of the average human body is Nitrogen atoms originating in crude oil.
This tells us nothing about the Carbon content, or other elements. How much of a Human's bodyweight comes from their food, and how much comes from crude oil derivatives supplementing the food during growing/raising/processing?
