Yogurt, whether it's in a travel-friendly tube, blended into a low-fat smoothie, or mixed with fruit and granola and kept in a lidded storage container in the cooler, is a great snack for kids and adults alike.
It adds calcium and vitamin D to your daily nutritional intake, which is good for the health of your bones, teeth and other bodily functions. Most brands also contain probiotics (check the label for live active cultures). Probiotics are live, friendly bacteria that help keep our digestive system running smoothly, and depending on the type of microorganisms, may also help reduce the risk or severity of some infections and other conditions (something to think about if you are prone to travelers' diarrhea).
In addition, yogurt may also help keep blood pressure levels from climbing too high. A study published in the American Journal of Clinical Nutrition suggested that adults who ate two or more servings of low-fat dairy every day had a 54 percent reduction in their risk for developing hypertension than their peers who ate smaller amounts [source: Pressner].
