If your child isn’t big on milk, offering chocolate milk could actually do her body good—extra sugar notwithstanding. Research shows flavored-milk drinkers actually have body-fat levels lower than or comparable to kids who don’t drink milk. Plus, both low- and nonfat white and chocolate milk provide important nutrients that many children lack, like calcium, vitamin D, potassium and magnesium, says Mary Murphy, RD, who coauthored a study on the benefits of milk. If your child is happy with plain milk, it’s best to avoid more sweets. But if flavored milk is the only kind she’ll drink, bring on the chocolate-milk mustache.
