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 However, product information and weblinks may be out of date.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

Lactose and Dextrose

Here's an unusual question I received.

After I got very ill I again looked at the ingredients and spotted dextrose. Are they similar and do you get others who have to also avoid too much dextrose?

Both lactose and dextrose are sugars but the resemblance stops there. Dextrose is in fact another name for glucose. Glucose is not only one of the sugars you get if you properly digest lactose, but it is the body's basic energy source. All sugars and carbohydrates break down to glucose, or another sugar that gets converted to glucose. You need it to keep your body going.

So nobody ever gets symptoms from glucose. If glucose bothered you, you'd be dead before you got a chance to check the ingredients list.
