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 However, product information and weblinks may be out of date.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

Does Quitting Dairy Makes You More Intolerant?

Kudos to The Toronto Globe and Mail for a solid answer to a question that I've gotten many times, If I quit dairy completely, will I become more intolerant?

Dr. Sheila Wijayasinghe breaks the bad news:

Given the large number of individuals who suffer from lactose intolerance, the possibility of developing a tolerance over time would be quite welcomed. Unfortunately, the body’s ability to produce lactase cannot be changed, so quitting dairy altogether does not increase intolerance as the amount of the enzyme remains the same.

The brainy doctor does understand the other side of the equation equally well and has some encouraging words:
Every individual is unique and has different amounts of the enzyme which is why certain people with lactose intolerance can take in larger amounts of dairy products than others. While you cannot build it up, you can test your tolerance level by gradually introducing small amounts of lactose containing products to see how much your body can handle.

Introducing small but constant amounts of lactase-producing probiotics, such as those in yogurt and other dairy products with live and active cultures or pills that contain the same, should increase tolerance as well.

A good answer, from one of the world's leading newspapers.
