According to a study of 200 people, eating kottu and fried rice all the time does bad things to your cholesterol and liver. The problem seems to be the oil, which is also used to fry other stuff. They also mention cockroaches getting chopped in there but I think that A) this is exaggerated and B) insects aren’t bad for you. There seems to be a scientific point (fried foods are bad for your health) mixed with a bit of speculation (the food is massively unhygienic).
I’m not saying the food is especially clean, it seems not, but their study seems scientifically limited to the insight that kottu and fried rice are bad for you. Which they are, so they shouldn’t be eaten all the time. We’ve been trying to compare all the different Pilawoos for YAMU and at one point ate about three kottus in a night (portions of). I felt dramatically ill, it’s a bad idea. I can also mention that eating kottu after two days in the fridge is also bad.
So it’s not exactly a news flash. Kottu and fried rice are not especially good for you. Kottu the website is.
