Myth 9: Juice is a healthy thirst quencher
Though 100 percent fruit juice is definitely more nutritious than soda, it shouldn't be the only drink your child reaches for when she's thirsty. "There have to be limits on a child's juice intake," Zelman says. "Otherwise, it will decrease her appetite for more nutritious foods and may displace milk as a beverage." What's more, because of the high sugar content of juice, drinking an excessive amount can harm teeth or cause stomach upset in babies. Nutritionists often recommend limiting a toddler's juice consumption to about 4 to 6 ounces a day; older kids should try not to drink more than about 12 ounces a day. "Offer juice as a treat, not a thirst quencher," Hattner advises. "Water is a better choice when your child is thirsty."
