The Lactose Intolerance Clearinghouse Has Moved.

My old website can be found at 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 or or 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.

Kosher and Parve Food Online

With Rosh Hashanah coming up next week, it's time to take a look at kosher foods available over the Internet.

Remember, it's not "kosher" that you want to look for necessarily, it's "pareve" or "parve." People who keep kosher must strictly separate meat from dairy. Dairy products can be kosher, of course, so that's why looking for kosher isn't enough. However, many foods are neither meat nor milk. They are neutral, and that's what parve means, however people might want to spell it. (Parve gives more hits than pareve in Google.)

There is no symbol that indicates that a food is parve. The word is always spelled out in full. (A "P" indicates that the food is kosher for Passover, notthat it is parve.)

Although there has been some controversy about the fine details of just how strict the enforcement of the prohibition of dairy products or dairy derivatives might be in theory, in practice I've never come across a parve product that contained any dairy. And Robyn Kozierok's Parve FAQ at makes this even more explicit:

Parve food may contain no detectable amounts of either meat or milk. This means zero. There are other cases in kosher law where an impurity of one part in sixty is permitted. This one-part-in-sixty rule does NOT apply to the classification "Parve". I mention this because once in a while one might hear from somebody who erroneously claims that parve food is allowed to contain very small amounts of milk.

Parve food may not contain any food derived from milk or meat ither. Thus casein, whey, lactose, and any other milk derivative renders a food dairy.

There do exist the occasional recalls of products that weren't supposed to contain dairy and do, but that can happen to any product at any time and nothing on the label can prevent that.

Some of the major kosher food shopping sites include:

Avi Glatt Kosher.

Kosher Gourmet Mart.

Shop Online at Manischewitz.

In Canada,
Kosher Food Online.

As always, I am not recommending or endorsing these sites, just providing information about their existence.
