Because of spam, I personally moderate all comments left on my blog. However, because of health issues, I will not be able to do so in the future.

If you have a personal question about LI or any related topic you can send me an email at I will try to respond.

Otherwise, this blog is now a legacy site, meaning that I am not updating it any longer. The basic information about LI is still sound. However, product information and weblinks may be out of date.

In addition, my old website, Planet Lactose, has been taken down because of the age of the information. Unfortunately, that means links to the site on this blog will no longer work.

For quick offline reference, you can purchase Planet Lactose: The Best of the Blog as an ebook on or Almost 100,000 words on LI, allergies, milk products, milk-free products, and the genetics of intolerance, along with large helpings of the weirdness that is the Net.

Sheep's Milk - Less Lactose?

Slim Ewe is not a user id on MySpace, a curseword on the Sopranos, or the winner of Nashville Idol. It's the latest fad form of dairy, ice cream made from whole sheep's milk. featured Jess Halliday's article, The healthy potential of sheep’s milk, on David Baker, owner of Styles Farm in the sourthwest of England, who's been making ice cream from sheep's milk for the past 18 years.

So why is this of interest to us? Because of the usual nutty claim.

According to market analyst Mintel, non-cow milks (sheep and goat) currently have a 0.8 per cent share of the white milk market value. The market is growing – but not so much because of the healthy profile (indeed the higher fat content of the milk is a drawback) but because of lower lactose content than cow's milk, making it more suitable for people with a perceived intolerance.

Of course, the article provides nothing to back up the claim that non-cow milks have a lower lactose content than cow's milk. If you want facts about milk, the first place to look is, that's right, my web site. My Lactose Zoo page gives average lactose content for over 30 animal milks.

    Cow 3.7-5.1%

    Goat 4.1-4.7%

    Sheep 4.6-5.4%

Even if you assume – correctly – that most cow's milk is at the higher end of the scale and sheep's milk is at the lower end, the difference is a few tenths of a percentage point at most. Not enough to make any noticeable difference in anyone's symptoms.

Your ability to have Slim Ewe will be almost exactly that of your ability to have cow's milk ice cream. You shouldn't feel any difference in lactose content.

But the claims just keep on comin'.
