Theory about height from my normie firend

[Helvetier]

His theory regarding the height of Tamils and Indians

In Switzerland, Tamils are on average quite tall, usually taller than us Swiss ourselves (not officially; we just noticed this in everyday life).
What's also noticeable is that the parents are usually very short. His theory is that the parents who grew up in Southeast Asia, where they only ate plants and didn't drink milk, weren't able to reach their full potential. But since they emigrated to Switzerland, and their sons ate meat and drank milk there, they reached their full potential.
What do you think about his theory?
