What would be an interesting persuasive speech topic on nutrition?

Why lactose products can cause you to gain weight? How GMO's have been linked to effecting people's health? How big fast food restaurants used certain colors to get your attention? I think something hard and different to do is to have a healthy diet while only eating fast food? Sounds like people have done those but yea

I am trying to think of something that hasn't been told to people over and over again.
