Nothing is easier or cheaper than a $1 mcdouble toots

I can find a ton of things in the grocery store cheaper per calorie.
Also, there is a high correlation between obesity and poor people, people who receive food benefits from the government. They can`t use their benefits at restaurants, but they can at the grocery store. They are clearly getting the majority of their calories from the grocery store (just like the majority of non-poor people do).
What does this mean? This means that the systematic demonzation of Fast Food is unfounded and steeped in pure ignorance.
