>>Spencer Wells: I’ve come to University College
London to start my quest. Geneticist Dallas Swallow
will show me how to figure out whether someone can
digest the sugar in milk.>>Dallas Swallow: You’re going
to do a lactose tolerance test.>>Spencer Wells: I am.>>Dallas Swallow: The idea is
to look to see what the level of glucose is in the blood of the volunteer before the
lactose load has been taken.>>Spencer Wells: After measuring my
baseline glucose level, I now have to chug
a liter of milk.>>Dallas Swallow: You’re
allowed to breathe in between. It’s all right.>>Spencer Wells: If my body
is still making lactase, my blood glucose will shoot up. After I drank the milk,
here is what happened. My doubt about it, my lactase
enzyme is still working.
