The Lactose Intolerance Clearinghouse Has Moved.

My old website can be found at I am no longer updating the site, so there will be dead links. The static information provided by me is still sound.

For quick offline reference, you can purchase Planet Lactose: The Best of the Blog as an ebook on or or or a whole lot of other places that Smashwords is suppose to distribute the book to. 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.

I suffer the universal malady of spam and adbots, so I moderate comments here. That may mean you'll see a long lag before I remember to check the site and approve them. Despite the gap, you'll always get your say. I read every single one, and every legitimate one gets posted.

Report From the LI Conference, part 22

First prebiotics and then, logically, probiotics. It's like scientists were methodical or something.

Strategies for Managing Individuals With Diagnosed Lactose Intolerance: Probiotics

As I also reported yesterday, probiotics are bacteria or other organisms that produce beneficial effects. More specifically, getting bacteria that can digest lactose (by making their own lactase) into the large intestine means that they can reduced or eliminate symptoms by digesting the lactose that reaches them before it can ferment and give off gas.

The evidence, as usual, is small and mixed. You need to read the presentation summary carefully to realize that what it means to you isn't the same as what it means to scientists. Researchers may get excited by knowing that certain bacteria give better results in breath hydrogen tests, because that may point the way to better delivery mechanisms or knowledge of when and how to take them.

What's of far more importance to you here and now is that any of the probiotics will give symptom relief. Streptococcus thermophilus (ST) and Lactobacillus bulgaricus (LB) are the types found in yogurt, but you have to ensure that you get yogurt with the National Yogurt Association LAC seal that indicates that "live and active" cultures will be in the finished product. Other types are used in probiotic capsules, including Bifidobacterium and Lactobacillus acidophilus. Those should work, but the evidence is sketchier.
