More calories and nutrients = more growth

Better nutrition and likely epigenetics from the better nutrion

>Will this trend continue, and 7ft tall people become an average 500 years from now?
Without genetic engineering I doubt so. We'll peak between 180 cm and 190 cm.

Humans were actually tall in the neolithic but agriculture fucked us over.

I recall the Romans talking about how Germanic troops were tall as fuck
Could this be appropriated to their nutrition or is there no reputable evidence on Germanic height?

Being taller means longer strides for more energy efficient movement. We probably won't get much thinner as a species unless our heads do the same thing, humans already have a relatively huge problem giving natural birth due to our thinness.

Probably nutrition and genetics. Celts, Germans, and Scythians were noted for their great height because they had an animal protein rich diet and Northern Europeans tend to be quite tall compared to Southern Europeans.

more food, less disease.
Possibly further interbreeding with yperboreans

Nutrients. It can happen in only a few generations, the tallest North Korean is a full head shorter than the average South Korean.

High protein intake during developmental stages correlates with tallness.
