Are There More Hormones in Whole Milk?

1/14/2014

We have so many choices in our grocery store's dairy case - whole milk, heavy whipping cream, 2% cheese, fat-free skim yogurt. But are there more steroid hormones in the full-fat versions of dairy products? If so, are high-fat dairy products, like whole milk and whipping cream, more likely to have more steroids than those dairy products with less fat, like fat free/skim milk?  

True? Or Not? "Food from organic and free-range farm animals is safer than animals raised in modern confinement buildings."

The popularity of organic and other niche-market products has increased in recent years primarily boosted by consumer perceptions that they are healthier and of higher quality. There is limited scientific data to support or refute the safety of such products.

Studies have found that pathogen prevalence is actually higher in niche market/ free range antibiotic-free farm animal production systems compared to conventional confinement operations.
