I think a lot of studies have tried to build a correlation between TV watching and nutrition habits. The problem is not with TV watching, rather it is the lack of physical activity. I was surprised to learn recently that even though TV watching is positively related to higher BMI, the effect is very small and not significant from a clinical point of view.

I think that if used properly, TV can be a good educational medium. Having said that, your point about regulating what children watch is right on the mark.

Thanks again
