Is our height determined by genetics or by nutrition?

How much of human height is genetic and how much is determined by diet?

Our height is determined by the action of DNA cells in human chromosomes. Even tho we all have the same cells, our cell activity tends to follow the ones of our parents.

The human max. height is determined by our genes, but it can be lessened by poor nutrition.

There is no diet that can add to our genetically determined maximum height, though.
