I don't think so because many parents can't afford to feed their kids healthy meals, so the laws would disproportionatly punish low income families. Instead, the government should provide kids with healthy food themselves, for example with free, good quality school lunches.
Personally no some can’t afford and you can’t really forcé a child to to eat. Also healthy foods don’t always mean “healthy” I don’t think restricting what children eat will help a lot because when they get older they may try to make up for the foods they weren’t allowed to eat by eating it in adulthood and that weight sticks. Also with eating disorders parents sometimes can’t stop them and it sure be child abuse if they held them down and forced them to eat.
