Yes, it would....I feel everybody would benefit from some source of proper nutrition....but you can educate people (parents) all you want, but it's up to them...and in so many cases, the parents don't give a damn one way or the other...as long as the kids don't bother them to cook and as long as there is food (no matter if it's junk food) in the house.....Even if there is junk food in the fridge...even HRS won't do anything....Some kids live off hot dogs and bologna (which is cheap)....
And in a lot of cases, it's the kids who do the cooking...for the parents...Or calling out for pizza several times a week....It's called "being lazy"....
It's summer...and my boys are home today (no plans)....are they sitting around eating junk food and on the Internet?...NO...one is outside washing the car inside and out.....and one is weeding the flower garden and will cut down bushes along the river bank....their rooms have been cleaned up and dusted....I find chores to keep them off their azzes...keeping them active....and out of the kitchen....If they want to go to the store....they have a skateboard and a bike, even 2 feet for transportation....it's only about a half-mile......
Keeping ur child active, into sports, swimming during the summer, whatever it is to have them outside to work up a good sweat, working those calories off!...Same as for adults....
