I just read the funniest article where this woman went to a nutritionalist about her overweight daughter who pigged out on junk, especially chocolate. She was all worried and the woman told her to stock up one cabinet solely filled with chocolate and tell her daughter it was all hers. She said the first day the girl pigged out, the second not so much and by the end of the week, the girl had one or two pieces and that was it and was actually losing weight after week four! :) It was about trust, knowledge and allowing kids to make their own choices and not feeling so controlled or it was with this girl. When you ban something it becomes more interesting for the children. I think it really doesn't give them a chance to make good choices when you ban it. By the way, just read a study that HIGH fructose sugar is not any more harmful then sugar. Sugar has been around for thousands of years.
My kids are young, so of course I keep track of what they are eating when, I don't allow free range though I really actually trust them.
I have always allowed junk to a degree, they eat very healthy! They love fresh and raw veggies and fruits, we eat little to no red meat and all of that stuff. When I was a kid we didn't have junk in the house, only on holidays when my mom baked. I would go to a friends house and eat five twinkies because I wanted it so badly! :)
I have taught my kids there is a reason not to eat too much junk and to take care of their bodies.
I have let them indulge and those few times (easter, halloween) one or both has ended up with tummy aches so they are very aware of what too much of anything can do to you and are very good about eating a "few" M&Ms and not over do it. That is just practice and not forbidding it.
I have a friend that absolutely bans it for her son and I see her son suffering at bday parties, school parties as they are really hard core. It is so unfair to him! He is old enough that if she explained and educated I bet he would make good decisions without her hovering and being so controlling. Sugar is not evil I have told her this, given her articles and so on. I showed her a chart even of safe levels per day per age and weight of a child.
He is wanting so bad to eat in and be with his friends, she has actually tried to ban it in his class!! He is being so set apart due to the restrictions his parents have put on him. One day when he is older, he is going to go hog wild on junk, he doesn't understand why he cannot have a little sugar or his parents not trusting him with it. NO it isn't due to allergies but that his parents think all sugar in every form is sinful for kids or something. THOUGH THESE SAME parents will eat it when the children are in bed so don't get me started. The mom will put two tablespoons of sugar in her coffee!!!!!
I think age should gauge of free range or not. How well you can trust they will make the right choices. I educate my kids on what foods give them what benefits and both are very eager to be healthy.
It only takes once of pigging out on something, getting to the point of near puking that will turn a child around, hee hee.
Kids just want a treat now and again. I ban sodas of any kind as I think there is no point, it is empty calories and leads to trouble. They know their friends get sodas and I tell them how much sugar is in those and say "well half of one of those would be all the sugar you could have, so would you want half a sprite or a few yummies during the day" of course they pick a few yummies. I allow only a small glass of juice with breakfast.
My kids have dessert only if they ate a healthy dinner, then it is pudding, maybe a cookie or something from their Valentine bag. I can honestly say because I have let them make choices about their candy load, from holidays that I have to throw out candy every holiday. They got lifesaver books and kisses in their stockings, those were eaten that first week now I had to throw them out at Valentines Day, they both got goodies from class parties, that will be thrown out I bet by Easter. They know moderation at at 4 and 7 sure they would go hog wild if I let the, my four year old in particular, but at the same time they eat some and don't ask for more so I am really proud. I gave my seven year old a bag of candy kisses (the mini's) she ate half and twisted the top and handed them back saying she was done for now. That is huge to me!
Sorry didn't mean to write a novel here! :) I think it is your choice, you just need to educate your kids and help them continue their eating habits well into their adulthood.
