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 However, product information and weblinks may be out of date.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.

Late Breaking News. Darwin Not Lactose Intolerant

You may not remember the kerfluffle in the news a couple of years ago when some researchers announced that they had determined that the cause of Charles Darwin's chronic illness was lactose intolerance. It was one of the first items I posted on the blog.

In a recent issue of Notes and records of the Royal Society of London, which I keep on the coffee table right next to US magazine, a pair of Chilean doctors [I'm not making any of this up] have concluded that he suffered from Crohn's Disease.

This explains his upper abdominal pain, his flatulence and vomiting, as well as his articular and neurological symptoms, his 'extreme fatigue', low fever and especially the chronic, relapsing course of his illness that evolved in bouts, did not affect his life expectancy and decreased with old age, and also the time of life at which it started. It apparently does not explain, however, many of his cutaneous symptoms.

They rule out lactose intolerance as a cause.

I'm so relieved.
