Now I would like to point out that Genetics 100% play a role in how tall you are, they determine how tall you are and everything about you in fact (hair color, skin color, penis size, hormone levels etc)
Not enough food can stunt height that is true but your height is in fact determined by your genes.
My example is that Asian people are naturally shorter even if you feed them which of course in all modern Asian countries like Japan, Hong Kong, Singapore, Taiwan they are far from starving but their natural height will always be around 2 inches shorter than a white person.
Another example is the USA has an extremely high rate of fat people (clearly not underfed or stunted) but most European countries that have in fact lower rates of fat people have taller populations of people.
This again is not because of diet but all because the USA is very diverse with many races such as Latino's Asians and Hispanics and others etc. So the average height is a little lower.
Mexico is also a country with high rates of fat people but they also are far shorter than Europeans. The reason is the different genes.
The North Europeans are the tallest naturally also out of Europe. The British are hardly starving but their genes determine why they will always be an inch of two shorter than the North Europeans.
I am annoyed at how BS Wiki has become in fact.
Wiki even uses this single picture and makes out it's representative of the world?

So they claim that just because in this single picture the American and British soldiers are taller then somehow that means that all British and Americans are taller?
When in reality that picture was taken by the allies and of course they selected themselves positively and it's propaganda if anything.
In reality the other countries represented in that picture such as Austria, Italy, Germany, Hungary (ww2) enemies are not in fact shorter people.
The world studies speak for themselves.
Average height of a man in the USA is 5'9''. Germany is 5'10'' and Austria 5'10.5''.
Hungary is also 5'10''. Italy is 5'10''.
As you can see they are at least the same if not a tad taller.
I get annoyed when stuff is misrepresented.
