Organic Milk Found To Be Low In Important Mineral Nutrients

Although organic farming has many benefits, one drawback is the fact that milk from cows on organic farms has lower concentrations of important nutrients, according to a Spanish study. The researchers compared the mineral and toxic elements of organic and conventional milk taken from 30 farms in northeast Spain. They found low levels of zinc, iodine and selenium in organic milk compared with conventional milk, mainly because organic farms do not routinely provide mineral diet supplements. The researchers suggested that organic farms provide animals with natural sources of iodine – an important element for children and pregnant women – such as seaweed.
