The problem is too many people are unaware of just how terrible for you these things are due to our education system being shit.

Why is our education system shit? Why aren't we taught basic nutrition? Simple really, because that would be racist!

No really, our education system is based on not leaving any children behind, because that's unfair. So they teach to the lowest common denominator AKA sub brainlet IQ 70 nogs. So the subjects that subhumans take the longest to figure out ( Math, Science, Literature, and History ) are all way behind schedule in comparison to other countries that don't have this retarded system. The result is that since K-6 spends so much time on the basics there is no time to teach classes that go beyond the basics. So classes on economics, geopolitics, and nutritional science all have to wait until college. 

TL;DR Niggers and their leftist enablers are dragging the rest of the country down.
