Very few people are malnourished enough for it to affect their height these days.

As the maps in the following article show this is not true.  There are many countries where poor sanitation and poor diet are still restricting height.  Furthermore, as shown in the same article a number of developed nations have been dipping in height since the 70s because of the availability of cheaply produced poorer quality food - processed and fast food.

Even now we see north south divide in the UK with Scottish men now shorter than their English counterparts - previously they were taller.  More details in the following book:

Genetics is the key factor. Those are secondary and can help only so much. But with a 5'0 non stunted dad and a 5'0 non stunted mom, good luck getting to 6'2 by 'optimizing nutrition and disease'

You don't want to do LL but stick on this forum? May I ask why? It's okay if you don't want to answer

He’s right, though.

Heritability allows us to examine how genetics directly impact an individual's height. For example, a population of white men has a heritability of 80 percent and an average height of 178 centimeters (roughly five feet, 10 inches). If we meet a white man in the street who is 183 cm (six feet) tall, the heritability tells us what fraction of his extra height is caused by genetic variants and what fraction is due to his environment (dietary habit and lifestyle). The man is five centimeters taller than the average. Thus, 80 percent of the extra five centimeters, or four centimeters, is due to genetic variants, whereas one centimeter is due to environmental effects, such as nutrition.

Any idiot would know genetics is the number 1 factor. Nobody's talking about 5'0 non stunted dad and a 5'0 non stunted mom producing a 6'2 kid by 'optimizing nutrition and disease'. 2"-4" make a significant impact on someone's life.

I agree, but did you read the example included in my previous post? 1 centimeter!

There’s no way you can gain 2 to 4 inches just by optimizing your nutrition.

LOL nutrition is t r a s h compared to GENETICS.
