Healthy food is not young people's favourite because they probably haven't tried it yet! There are Lots of vegetables and fruits that they didn't Even hear about like : Avocados , Coconuts , Mangos and Lots more! They might only have tried hamburgers french fries and liked that . Also the media doesn't promote Healthy stuff and promotes things such as : Starbucks McDonalds and other unhealthy stuff! If parents would Teach their children how to eat Healthy and buy them fruits and vegetables a lot more I'm sure there wouldn't be So many people suffering from obesity ! Hope it Helped you!
