A container of yogurt may seem like one of the least complicated foods in your refrigerator, but after 60, what you eat regularly can matter more as maintaining muscle and bone becomes increasingly important. Eating yogurt after 60 can provide protein, calcium, potassium, B vitamins and, depending on the product, vitamin D and live bacterial cultures. Research has also found associations between yogurt consumption and measures including bone density and physical function in older adults, although that doesn’t prove yogurt itself caused those differences. Just as importantly, a cup of plain yogurt is relatively inexpensive, requires no cooking and can work at breakfast, lunch or as a snack. Here’s what the research actually suggests—and what to check on the label before making yogurt an everyday habit.
