A nurse is providing teaching about nutrition to the guardian of a school-age child who has lactose intolerance. The nurse should identify which the following foods as the best source of calcium?

A. 1 cup raw broccoli: Broccoli is a lactose-free vegetable that provides a good source of calcium, making it an excellent option for children with lactose intolerance who need to maintain bone health. B. One slice white bread: White bread provides only minimal calcium, unless fortified, and does not contribute significantly to daily calcium requirements. It is not considered a reliable source of calcium. C. 2 tbsp peanut butter: Peanut butter contains protein and some minerals, but it is low in calcium. It cannot meet the nutritional needs for bone development in children with lactose intolerance. D. One poached egg: Eggs provide protein and other nutrients but very little calcium. They are not a suitable substitute for maintaining adequate calcium intake.
