A video shows what happens when inside your digestive system when you eat ramen noodles. And it ain't pretty.

Dr. Braden Kuo, a doctor at Massachusetts General Hospital, placed a camera in people who had eaten processed ramen noodles and natural ramen noodles. The difference is stark.

“What we’re seeing here is a stomach contracting back and forth as it’s trying to grind up the ramen noodles,” Dr. Kuo said in the video.

Processed, packaged ramen noodles, the college student's staple meal, was first introduced into American diets in the 1970s. It's popular because it's really cheap, often costing less than a dollar a meal.

But ramen packs a whopping 875mg of sodium, which is almost half of the recommended daily intake, barely any nutritional value, and is know to cause certain heart risks in women. 

So, put down that ramen.
