This article, entitled "Are There More Hormones in Whole Milk?," comes from Carolyn O'Neil at BestFoodFacts.org.
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?
To answer this question, we reached out to Dr. Ann Macrina, a research and teaching associate and dairy expert, at Penn State.
Dr. Ann Macrina:
"In general, higher fat dairy products contain a higher concentration of steroid hormones. However, the exact distribution between the fat and non-fat fractions really depends on the particular steroid hormone. Some steroids are more lipiphilic (more likely to combine with fat) than others.
"But, keep in mind that the overall quantity of steroid hormones in dairy products, even high-fat dairy products, is much lower than the amounts produced naturally by the body.
