The National Dairy Council, a dairy marketing and nutrition organization, wrote in its Oct. 1999 Nutrition & Health News Alert titled "Little Kids Can Benefit from Calcium, Without Concern About Iron Loss," published on its website:

“Iron and calcium are two nutrients important for young children’s growth and development. Despite suggestions that too much calcium may decrease iron storage in red blood cells, a new study shows higher calcium intakes do not impact iron absorption. Researchers placed preschool children ages 3-5 on two diets: a low-calcium diet (about 500 mg) and a high-calcium diet (about 1,000 mg). The results showed no difference in iron absorption. Additionally, children who increased their calcium intakes also increased their calcium absorption, which may benefit bone growth and development. Milk, cheese and yogurt foods were the primary sources of calcium for children in the study. The authors conclude that kids can benefit from more calcium without negatively affecting their iron absorption or increasing the risk of iron deficiency anemia.”
