Children who drink more milk do not necessarily.Develop healthier bones, researchers said in a report that stresses exercise and modest consumption of calcium-rich foods such as tofu and broccoli.
Appearing in the journal Pediatrics, the report drew its conclusions from previously published studies and was written by researchers from the Physicians Committee for Responsible Medicine, which advocates a strict vegetarian diet.
"Under scientific scrutiny, the support for the milk myth crumbles. This analysis of 58 published studies shows that the evidence on which US dairy intake recommendations are based is scant," said study author Dr. Amy Lanou in a statement.
研究学者Dr. Amy Lanou 在声明中写道：“在科学的详细审查下，牛奶补钙神话的支柱被彻底粉碎。对58份公布研究的分析表明仅仅基于美国乳制品推荐摄入量作为补钙证据是远远不足的。”
Some earlier studies that extol dairy products as a calcium source have been funded at least in part by the dairy industry.
The US 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 the Physicians Committee's report 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 get the absorbable calcium found in one cup of cow's milk 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, the report said.
Data was scarce on the effect of calcium intake for children younger than 7 years, the report said. Dairy products provide 18 percent of the total energy and 25 percent of the total fat intake in the diets of American children, who are developing increasing rates of obesity, it said.
