Chances are, your tween has strong opinions about what foods she does and doesn't like. That's OK, but there are plenty of foods that can ensure she stays healthy.
Too much sugar can lead not only to dental problems but also to obesity; high-caffeine energy drinks can cause jitters, insomnia and heart palpitations; and tweens' calcium intake is very important for bone density in adulthood. Talk to your child about proper nutrition, and introduce her to resources such as the Center for Disease Control and Prevention's tween nutrition page, which has games that teach tweens about good food choices. And here's the toughest part -- if you lead by example and keep your kitchen stocked with healthy foods, you'll have more success enforcing this tween limit. Remember, good eating habits can last the rest of her life. Likewise, eating disorders can threaten her future.
Ka-ching! That's the sound of the next tween limit we'll tackle.
