On Stalinist Measures

It's probably a good idea to make school food healthier, but I don't know if I like the implementation:

Students at the beginning of the school year were weighed, their height measured and their blood pressure and pulse recorded. Those same measurements will be taken in April. The institute has paid for the $10,000 extra cost. Hollar said the obesity rate at the school hadn't been calculated.

Can't we just assume that kids would be better off with healthier food being served to them? Lining up little elementary school kiddos to be weighed and measured seems as grim a scene as the dishes being served.
