Final answer:
A yogurt that states it provides 30 percent of the Daily Value for calcium is considered high in calcium, which is important for bone health and other bodily functions.
Step-by-step explanation:
If a yogurt states that a serving provides 30 percent of the Daily Value for calcium, it contains a high amount of calcium. The Daily Values are reference amounts of nutrients to consume or not to exceed each day and are used to calculate the percent Daily Value on the labels of foods and dietary supplements. As a general guide, if a single serving of food provides 20 percent or more of the Daily Value for a nutrient, it is considered high in that nutrient. Therefore, a yogurt containing 30 percent of the Daily Value for calcium would be high in calcium, which is essential for healthy bones and teeth, among other bodily functions.
