Hot Chips and MSG

I just read the two news. The information told us that hot chips and MSG are not good for health. In fact, most of people like hot chips, especially children. My children like MacDonald's chips. I think if we eat a little bit of chips , that is alright.
When I cook, I use to put chicken powder and a little bit of MSG. This habit came from my father. My husband likes too. In fact , some of the vegetables have the ingredient of MSG. We've been used MSG for many years, so far I don't suffer eye damage. In my opinion, as the same way as hot chips, don't take too much and eat more fruit and vegetable, this is a safe way.
