When you wake up and go to the kitchen to pour yourself a cold glass of milk, it seems you are filling your body with calcium, vitamins, and an abundance of goodness. That seemingly white beverage may look innocent, but the hidden ingredients packed into the liquid that is a popular staple in the American diet are anything but.
According to a recent study published in the Journal of Agricultural and Food Chemistry, scientists have found through analysis that one single glass of milk can contain a delightful (or not) medley of up to 20 different kinds of painkillers, antibiotics and growth hormones (http://pubs.acs.org/doi/abs/10.1021…). These medicinal residues, found in samples of cow, goat, and human breast milk, are from a variety of chemicals used to treat animal and human illness.
This research revealed that cow, goat, and human breast milk tested for traces of numerous anti-inflammatory drugs such as niflumic acid, mefenamic acid, flunixin, ibuprofen, diclofenac and ketoprofen — all of which are commonly used painkillers for animals and humans.
Traces of other drugs, such as lipid regulators, anti-epileptics, beta-blockers, antibiotics and various hormones (such as ethinylestradiol and estrone) were found as well.
A total of 20 pharmacologically active substances were found in the various types of milk in the study. The highest quantities of drug residues and hormones were found in cow’s milk. Researchers used an extremely sensitive testing method, called Gas Chromatography-Mass Spectrometry, in order to ensure the testing was successful and accurate.
According to an online article (http://www.dailymail.co.uk/sciencet…), the milk tested also contained the hormone 17-beta-estradiol, a form of the sex hormone oestrogen.
