The U.S. government has gradually increased recommendations for daily calcium intake, largely from dairy products, to between 800 and 1,300 milligrams to promote healthy bones and prevent osteoporosis. But a report published in a medical journal said boosting consumption of milk or other dairy products was not necessarily the best way to provide the minimal calcium intake of at least 400 milligrams per day.
Other ways to obtain the absorbable calcium include a cup of fortified orange juice, a cup of cooked kale or turnip greens, two packages of instant oats, two-thirds cup of tofu, or 1 2/3 cups of broccoli. In a study conducted in 37 children, it was found that 27 did not support drinking more milk to boost calcium.Currently, available evidence does not support nutrition guidelines focused specifically on increasing milk or other dairy product intake for promoting child and adolescent bone mineralization.
It was concluded that exercise may be more important than increased calcium consumption in developing strong bones and was agreed that the ideal way to achieve the goal of healthy bones is to make sure children exercise and consume up to 1,300 milligrams a day of calcium.
