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 and my Lactose Intolerance Clearinghouse are now legacy sites, meaning that I am not updating them any longer. The basic information about LI is still sound. However, product information and weblinks may be out of date.

My old website can be found at

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.

Lactose and Phlegm

Excuse while I bang my head against the wall.

So much misinformation.

I won't give any names, but here's a quote from an actress about problems acting during her pregnancy:

She also had morning sickness but kept it from interfering with her work by eating hourly, mainly the cheese that she craved--problematic because products with lactose can clog the throat.

No they can't. Lactose intolerance affects the intestines. Period.

According to this page, the myth that milk causes phlegm goes back to the writings of the 12th century rabbi, Maimonides, from his treatise On Ashtma. Who knew?

Modern medicine looks at it differently. It may be possible that certain people with cow's milk dairy protein allergies may produce more phlegm. There are a million reactions that allergies can cause.

It's much more likely that you simply don't get more phlegm from milk. You may feel a film if you drink milk, or eat cheese, or you may just have heard the myth and make a false association.

But lactose has nothing, but nothing, to do with it.
