But seriously... it's interesting if you ever see a street scene in Asia (Tokyo is a good example). The younger people tower over the elderly. This is due to the increased amount of sugar and protein in their diets since WWII. It's been called the "McDonald's Effect".
It's also worth noting that this is a common, global phenonmen. People all over the world were smaller 50 or a 100 years ago. Our diets have changed such that we now grow much larger than we used to. This has a negative impact upon some (massive increase in obesity) and has disasterous repercussions for some ethnic minorities; aborigines in Australia, native Americans in America etc), with even more dramatic increases in obesity and diebetes.
