For example, in an 18 month randomised controlled trial, British girls in the intervention group were asked to drink extra milk, whilst the control group maintained their usual diet. Consuming an approximate additional glass (186ml) of milk every day significantly increased intakes of protein, calcium, phosphorus, magnesium, zinc and riboflavin, whilst milk consumption and nutrient intake were unchanged in the control group10. In a US study of milk drinkers, both flavoured and plain, intakes of vitamin A, calcium, phosphorus, magnesium, potassium were significantly higher than non milk drinkers11. Indeed the Dietary Guidelines for Americans advisory committee report determined that without milk products, 19-50 year old women would reach only 44% of calcium recommendations, 57% of magnesium recommendations and 57% of potassium recommendations12.
