Along the same lines, those of us who are lactose-intolerant get a pretty good clean-out from a pint of Haagen-Dazs!

I hate to make light of lactose intolerant but I used to laugh at it because I thought it was a made up thing but no, I know someone who has it and it is no joke.

Made up? The majority of humans are lactose intolerant because they, like just about every other mammal, ‘turn off’ the gene for the enzyme lactase shortly after they cease being nursed.

In most Northern European populations, and some cattle herding African populations - there is a mutation in the control region that would result in the lactose gene being packaged up (i.e. turned off) in chromatin after breast milk was no longer part of the daily diet.

As a result some populations continue to produce lactase (the enzyme that digests lactose - the sugar in milk) throughout their life.
