Researchers led by Dr Jonathon Maguire at St Michael’s Hospital in Ontario, Canada examined how the intake of cow’s milk affected body stores of iron and vitamin D in more than 1,300 children aged between two and five.Iron is essential to make haemoglobin – the oxygen carrying component of red blood cells. While, vitamin D helps to control the amount of calcium and phosphate in the body, which are needed to keep bones and teeth healthy. Vitamin D deficiency can cause rickets and poor growth in children.
