Organic milk is produced without antibiotics or hormones, including bovine growth hormone (BGH) that is injected into cows to increase milk production. Organic milk cows have access to pasture – at least part of the time - and feed on grain or grass that is not treated with synthetic chemicals.  Research has traditionally shown that organic milk is equally nutritious as conventional milk, although for those who drink full-fat milk, a newer study from the UK showed organic milk to have fewer saturated fats and more beneficial fatty acids. People commonly buy organic milk to reduce their exposure to BGH and, although scientists say almost none enters the body, they don’t want to take a chance; however, it is more important to drink milk than it is to go organic, especially because organic may be twice as expensive as conventional milk.
