I hear this argument continuously, but it does not convince me. You imply that McDonalds is bad. Why is it so? Mostly because it's very calorie dense, not because it's actually bad for you. In that respect, McD does its job very well, too well even, but it's not the food itself that is bad, its over consumption.
How bad are ramen for you anyway? Consuming it as a large part of your diet, within your caloric intake and getting the rest of your needed vitamins from different sources (fruits, supplements even), would you get sick with time? Why are certain foods labeled as "bad" automatically? t seems this gets repeated Ad nauseam but most always, the accusation is unsubstantiated.
