I know of people who have opted for raw cow's milk. From what I've read raw milk is often ok for those with dairy allergies. Pasteurization kills off the probiotics and enzymes that help break down the proteins and make digestion easier. The protein in dairy products is often the culprit that causes allergic reactions.
Raw milk is expensive and I feel a little funny about purchasing it knowing it is against the law. You can skirt around the issue because of the "pet consumption only" label, but it still feels weird to me. It's a personal choice. I'm not judging anyone who does buy raw milk for their family, Scout's honor!
My solution came from Sally Fallon's Nourishing Traditions. She has a recipe for Coconut Milk Tonic which is nutritious and meets the needs for good fat and calcium that come from dairy milk.
I make mine a little differently, but the principle and basic ingredients are the same. If you decide that homemade coconut milk is a good choice for you, you might want to consider purchasing canned coconut milk by the case at Whole Foods. I get 10% off this way and their 365 brand is already a great price at $1.49 per can. The price per gallon works out to be a little more than $4. Not bad considering organic cow's milk is over $5 per gallon.
3 cans full fat coconut milk
1/8 tsp of pure stevia powder
3 tsp Dolomite powder
1 Tbsp vanilla (optional)
Fill a gallon pitcher about 2/3 full with the hottest water your sink can provide (or heat it on the stove, but hot water from the tap is faster and uses less dishes). Sprinkle Dolomite and stevia over water and stir until dissolved. Add coconut milk and stir again.
That's it. Not quite as simple as buying a carton at the store, but there's no extra ingredients either.
You might be wondering at this point what Dolomite is. It's a powdered form of calcium that your body easily absorbs. So now you are getting the calcium you need from your coconut milk too!
