Suarez FL, Savaiano DA, Levitt MD. A comparison of
symptoms after the consumption of milk or lactose-
hydrolyzed milk by people with self-reported severe
lactose intolerance. N Eng J Med 1999;333:1-4.
This study aimed to determine whether
lactase treated products were necessary in
lactose intolerant persons
Background:
Enzymes
are biomolecules that
catalyze chemical reactions
The enzyme lactase converts lactose into
glucose and galactose - HYDROLYSIS
lactose + H
2
O glucose + galactose
lactase
Note: In the experiment, the researchers hydrolyze
the milk that is given to one of the groups.
Lactose Intolerance
o
Some children are bor
n without the enzyme,
lactase
o
Many adults don’t make lactase after age 2.
•
Europeans and Americans have an autosomal
dominant gene that causes the continued
production of lactase
o
Symptoms
•
bloating, stomach cramps, gas, and diarrhea
after consumption of milk products
Are these products necessary for most
people or are we victims of marketing hype?
o
Hypothesis: Ingestion
of small amounts of
lactose (<240 ml/day) is associated with
digestive symptoms in people who are
lactose intolerant.
Study Design
o
Null Hypothesis: There is no relationship
between ingestion of sm
all amounts of milk
(< 240 ml) and digestive symptoms in lactose
intolerant people.
o
Experimental Group: 21
lactose-intolerant
adults
o
Control Group: 9 lact
ose-tolerant adults
Study Design
o
Controlled Variables: subjects avoided any
other dairy products for 1 week prior to the
experiment
o
Independent Variable: type
of milk – either
2% fat milk or lactose-hydrolyzed milk
o
Dependent Variables: ratings of GI
symptoms on a scale of
0 (none) through 5
(severe) for bloating,
pain, cramps, diarrhea;
also recorded “each passage of flatus”
Lactose intolerance was measured using
hydrogen gas in a breath test
Conclusions
o
Lactose intolerance was incorrectly self-
identified by 9/30 subjects
o
All subjects were able to tolerate 240 ml of
lactose per meal,
therefore the null
hypothesis was accepted.
o
The authors concluded that
there is little or
no need for expensive lactase digested
products in people who are lactose
intolerant.
