Why does the USA have the highest obesity rate ?

The fast food culture has been with us a long time.....and we have an increasing percentage of our population which is very poor and the cheapest food is the least healthy food. Lastly we are a country that does not really care much about our citizens, at least not like other civilized countries that are supposed to serve their people do. Since we do not care, we educate our people poorly....and that also is a contributing factor as a lot of Americans are just plain idiots.

Because people have money to afford eating at fast food restaurants..yet , ironically , liberals claim that healthy food is "expensive" ..What a joke!  Are bananas more expensive than one hamburger ? is boiling 2 gallons of water  from the tap more expensive than a soda ? is a dozen of eggs more expensive than a pizza from pizza hut ? 

Soda and Cheetos.

Because the FDA has approved addictive chemicals to be added to our food supply to make us all sick. Then we have to go to the medical industry and rely on prescription drugs to make us better. It's a win win for food companies and big Pharma.

Why do Russians smoke krokodil 

Every society in world history struggled to feed their own people. The US solved the problem: Capitalism. 

Because Liberals find comfort in food while calling Conservatives fat on Y!A all day 

Check with Fat Donnie on that one.

Because of stupid liberals that are scared to tell fat people they are slowly dying in order to avoid hurting their feelings.
