Could you tell me what are 2 possible health effects on children eating too many biscuits a day?

Weight gain: Eating too much of any food can cause weight gain. If a child eats only one type of food (kids go through food jags), they may miss out on other important nutrients. Try small portions of other foods at meals, offer healthy snacks, and give a multi-vitamin if your child is resistant to fruits and vegetables. Don't make meal times a battleground, but offer healthy choices.
