A Less Allergenic Option
Those who can’t tolerate cow milk might be able to tolerate goat milk. It is lower in both lactose and casein than cow’s milk (though it does contain both). If you can tolerate it, there are a number of reasons to consume goat milk.
For starters, the fat contained in goat’s milk is much better emulsified than in cow’s milk. This means the cream does not rise to the top, but rather remains suspended in the milk. For this reason, goat milk does not need to be homogenized, making the fat more bioavailable to us.
Similarity to Human Milk
Goat milk is also much closer, structurally, to human breast milk than cow milk is. It’s not as widely available in the U.S., but if you can get your hands on it and you have no problems digesting it, there’s no reason a nice glass of raw, whole goat milk can’t be included as part of your Paleo lifestyle.
