What’s in McDonald’s Fries

One of the most addictive food I've found are the french fries from McDonalds. You can't eat just one...order. A question was put forth to McDonalds..."Why do McDonald's french fries have 17 ingredients?". They actually have 19. They don't say which ingredient acts as the "crack". It seems the majority of them are part of the oil they cook them in. I didn't realize that they they get partially cooked at the factory, then cooked a second time at the restaurant. Grant Imahara gives you a complete breakdown.
