Whats the difference between fast food and slow food?

fast food hard questions. i thought first fast food was fast because you go through the drive through then i thought that makes no sense because its still called fast food when you go inside. but now i think slow food is when you go to a resturant and its meant just to sit down at. not just to order and go which you can do. and i think the quality is about the same. thanks for posting.

Years ago the words "fast food" referred to how much quicker it was to buy the food already prepared, like at a McDonalds, as compared tp how long it would take to make it from scratch at home.
Now fast food means mass produced, packaged ready to cook or just heat up, not fresh by any true meaning of the word and usually not of a quality that a person would serve out of thier home.

Beef patties injected with MSG laden water to add tase, parbroiled, (half cooked) french fries or hash brown patties dipped in sugar water, what passes for a vegetable picked before ripe and trucked across the country, or worse yet, flown in from another country.

nice topic...its very simple. fast food ends your life span fast whereas slow food makes you to live long...am i right?

That depends . I eat very slowly. so there is no difference between fast food and slow food for me . LOL
