Both harmful. Instant noodles itself is fried, fried food is very easy to deteriorate, you can imagine how much he put preservatives ah! And that seasoning packet in order to taste delicious, added a lot of monosodium glutamate, refined salt, spices and other unhygienic things! The sauce packet, not to mention, is full of oil, and after soaking, you'll find a lot of black sand-like stuff in the rest of the bowl. Do you know what that stuff is for? It's to fully absorb the flavors from the other condiments in the sauce packet ah and so on, so that the flavors can be fully utilized, it's quite dirty!
Outside vendors sell some of the things are also flavored to put a lot, so you can not eat his spoiled taste, so you think it is delicious. In fact, you don't know what kind of mess he's home without!
It's best not to eat instant noodles too often!
