L.:
First of all, let me tell you that "organic" and "hormone free" are not terms that mean the same thing as far as the FDA is concerned. Without getting into all of the fine print here, the FDA has regulations for what labels can say and even some of the things they label as "natural" or "organic" have other ingredients in them that are neither natural or organic.
If you're concerned about purchasing truly organic foods, then you want to look for the label that says "certified organic" because that is a higher quality (more restrictions, better standards, etc.) from the FDA's point of view.
Now, I have to respond here that I vehemently disagree with prior posts that the hormones are no big deal because they already occur in the animal. I'm going to give you a link to a recent article about this hormone (rBST or rBGH -- both made by mega-pharmaceutical company Monsanto) that raises some serious questions about whether or not this should be in our food supply. This is from the Organic Consumers Association, and they are a watch-dog consumers group that deals with all types of organic and health info -- and for good reason, given this article: http://www.organicconsumers.org/articles/article_11149.cfm
If you do any type of research on this, you will easily find that both Canada and the European Union have banned these hormones from their milk supply. Unfortunately, our pharmaceutical companies have huge money behind their lobbyists in Washington, D.C., so I don't wonder why it's still in (some of) our milk.
True, you pay more at the store for items that are grown with more care and fewer chemicals -- but I wonder what we'll pay in the long run if we just keep eating junk that includes additives, preservatives, hormones and the like.
And please don't assume that prior posts are correct when they basically tell you not to worry because the hormone already exists in the cow. Any woman who has taken birth control pills knows (or should have been told) that there are risks involved in taking synthetic hormones.
Likewise, there were thousands of aging women who were on Hormone Replacement Therapy (from the Premarin mares) who completely stopped when the HRT was linked to cancer and the like. I know humans and cows aren't the same -- but I'm not going to blindly assume that more of the same thing is good (or at least, nothing to worry about) -- especially in the case of what we're putting into our bodies.
By the way, I need to add here I'm by no means anti-milk or anything like that. My grandfather was a dairy farmer in southeast Michigan for many years and was respected for his practices in raising animals and supplying milk. I just want to see truth in labeling, and get the big-money folks out of the way of being honest. In the meantime, I'm going to keep doing my homework and research . . .
Best wishes!
