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 However, product information and weblinks may be out of date.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

Major Historic Lactose Tolerance Study Launched

With all the recent scientific attention - see my posts Dairying More Than 8000 Years Old and Genetic Map of Europe Features the Lactase Mutation - on the mutation that allows adults to drink milk without symptoms, the history of milking and milk drinking is becoming vital to the understanding of the spread of modern humans.

ScienceDaily reported that "In a major EU project, being launched today and coordinated by Uppsala University in Sweden, researchers will now study when and where this capacity emerged and what it entailed."

The researchers - 15 research teams with different specializations in genetics, organic chemistry, and archeology:

will follow the tracks of milk throughout Europe, making use of a model for the spread of genes in order to follow the dissemination of the mutation. In this model the frequency of the mutation increases along the 'frontline' of the dissemination¬-that is, we in Scandinavia, on the periphery, should thus have the highest frequency of the specific gene.

Fascinating stuff, even if we'll probably have to wait several years for the results of the research to start trickling in.
