10% of American kids don’t get enough vitamin D. That’s according to a recent study by USA Today. Washington County Public Health Administrator Edie Nebel says vitamin D is primarily obtained through sunlight and not enough time in the sun can result in a deficiency. Nebel says kids need at least ten to fifteen minutes of sun exposure a day along with the vitamin D found in foods. She says additional nutrition can be found in vitamin supplements. Nebel says kids need plenty of vitamin D in order for healthy bone development.
