Ramen not Roman and no they arent stryrofoam. They are rice noodles made from rice flour and they have a lot of fat in them. All carbs take longer to digest. Pasta in italian food takes a long time as well. The three day thing is a MYTH. Ive also heard three minths and three years. Nothing stays in the body that long. Even if it were ACTUALLY pure styrofoam it would be expelled in a few hours. Ramens digest in the same time as anything else. Ramens dont even make the top ten hardest to digest foods. Chicken nuggets are actually at the top.
