Abstract: We analyzed mean height of men born in the 1960s, 1970s and 1980s in 80 countries. Both height and the change in height during the last decades were correlated with N and P intake, as well as the N:P intake ratio. Rich countries had higher per capita N and P intake than poor countries (on average 19. 5 ± 0. 3 versus 9. 66 ± 0. 18 kg N y−1 and 2. 17 ± 0. 04 versus 1. 35 ± 0. 02 kg P y−1), and also larger increases in per capita N intake (12. 1 ± 2. 0% vs. 7. 0 ± 2. 1%) and P intake (7. 6 ± 1. 0% vs 6. 01 ± 0. 7%), during the period 1961–2009. The increasing gap in height trends between rich and poor countries is associated with an increasing gap in nutrition, so a more varied diet with higher N, P, and N:P intake is a key factor to improve food intake quality in poor countries and thus shorten the gap with rich countries. More N and P are needed with the consequent requirements for a better management of the socioeconomic and environmental associated problems.
