Reading labels on milk can be confusing: organic, rBst-free, pasteurized, skim, whole, etc. What do they all mean and what is the best kind to buy?
If you have access to it, I'm a big fan of raw milk for health reasons.
If you are limited to your local grocery store, you probably won't see raw milk on the shelf.
What you will see:
Organic milk: I'm all for organic milk. In fact, the raw milk we buy (when we can afford it) is organic. The bad news is that most of the organic milk you find in the store is ultra-pasteurized. Ultra-pasteurized milk is heated to high temperatures. This kills off bacteria and enzymes that actually aid in digestion. So, why do they do it? Well, mainly it's to give it a longer shelf life. Ultra-pasteurization means that the milk can last on the shelf longer without spoiling.
Not all organic milk is ultra-pasteurized, but a lot of it is, so be sure to read the label.
The difference with organic and traditional milk is a simple question of if what the cow ate was treated with pesticides. No pesticides+ following lots of government regulations = certified organic.
rBst free milk: rBst is a growth hormone. It boosts milk production in cows by about 20 gallons per day. People in favor of using it say that it has no known effects on humans and that it is similar to a naturally occuring hormone in cows. Besides increasing milk supply, rBst also increases udder infections, which can increase the need for antibiotics. Your best bet is to find milk that comes from cows not given rBst. Many brands proclaim "rBst free" on the label. Walmart's Great Value milk has been rBst free since March 2008 (Source).
Skim milk, 1% and 2%: The first thing that is a problem with these low-fat milks, is that the body needs fat to use the vitamins in them. When the fat is taken out, the body is unable to absorb fat soluble vitamins. To make the milk thicker, powdered milk is added to 1 and 2% milk. Powdered milk is made by spray drying milk. This damages (oxidizes) the cholesterol, and has been shown to increase cholesterol in our bodies. This kind of milk does not do a body good! In Real Food, What to eat and why, by Nina Planck, Nina reminds us that in the olden days, the poor would sell off their cream and be left with only skim milk... and sickly children.
My recommendation: When I can't buy raw, organic milk and I have the normal grocery store selection, I would first look at the organic milk. Does it say "ultra-pasteurized" or UHT on the label? If so, skip it. It's great the cows never had pesticides, but since everything (good and bad) has been cooked out anyway, that is almost irrelevant. If it is pasteurized only, go with organic. If not, look at your whole milk selection and choose one that says rBst free on the label.
