Yea, but if we've average 165, there will be some taller than 165 and some shorter than 165. We might as well have someone 190, we can use them to breed tall population. And but how do you achieve that just using nutrition? Effect of nutrition on height is overstated. Unless someone is malnutritioned, their height won't benefit much with better nutrition We can even see this in cattles, if you start with a short cattle, no matter how much you feed it for generations, they'll still he shorter than one you can get from tall breed.
