The Lactose Intolerance Clearinghouse Has Moved.

My old website can be found at www.stevecarper.com/li I am no longer updating the site, so there will be dead links. The static information provided by me is still sound.

For quick offline reference, you can purchase Planet Lactose: The Best of the Blog as an ebook on Smashwords.com or Amazon.com or BarnesandNoble.com or a whole lot of other places that Smashwords is suppose to distribute the book to. 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.

I suffer the universal malady of spam and adbots, so I moderate comments here. That may mean you'll see a long lag before I remember to check the site and approve them. Despite the gap, you'll always get your say. I read every single one, and every legitimate one gets posted.

Report from the LI Conference, part 12

Back from a short lunch we plunged directly into more presentations.

Aging: Lactose Intolerance and Calcium Absorption in the Elderly

We're a nation of just over 300,000,000 people. We're also an aging nation. People are living longer than ever before, and the demographic bulge caused by the vastly increased birthrates that represent the baby boomer generation is moving to the older segment of the population. The first boomers are turning 64 this year. By the year 2030 there will be an estimated increase of 33 million people in the 65 and over age bracket, making a total of 25% of Americans. You can't blame the boomers entirely. The oldest will be only 84 that year but a full 5% of the population will be 85 or over then.

What happens to humans as they become older, an older population than ever before? Specifically, what do we know about the elderly and LI? As will be a woefully recurring theme, the answer is "next to nothing."

Although many studies have characterized the prevalence of lactose maldigestion and symptoms of lactose intolerance in various adult populations, there is surprisingly little information concerning this condition in the elderly, especially in the very old (>80 years). What little evidence is available indicates that the prevalence of lactose maldigestion may increase with age in adults, but that symptoms of lactose intolerance do not increase with age.

Little evidence means little evidence. Apparently fewer than a hundred elderly in total have ever been investigated in LI studies.

And those meager results are big time compared to the number of elderly patients tested to see whether lactose malabsorption affects calcium absorption. We just don't know. The possible good news is that tests on younger patients don't show any difference. Keep on having calcium in whatever form you like.
