Parents in the UK - Should it be illegal to sell junk food to children under 16?

that's nearly all food and drink what they meant to do just eat fruit and veg and just drink juice or water? well that's a healthy diet isn't it everyone needs a mix of everything for a healthy diet mind you some of the stuff on that list is in fruit and veg and juice so they cant even have them according to you. its wrong everyone should be aloud to eat and drink what they want
