Lactose-intolerant people needed for study

The UCT/MRC Exercise Science and Sports Medicine Research Unit need both lactose intolerant and lactose tolerant people for a research study.

The UCT/MRC Exercise Science and Sports Medicine Research Unit, based at the Sports Science Institute of SA (SSISA) in Newlands, are recruiting both lactose intolerant and lactose tolerant people for a research study.  The aim of the study is to compare how self-reported lactose intolerant and lactose tolerant people cope with UV-treated cow’s milk versus regular pasteurised cow’s milk.

The study involves the participant coming in for two visits to the SSISA - each lasting 3.5 and 3 hours respectively.

How the study will be done

Visit 1: Questionnaire, height and weight measurements and donate a blood sample (± 1 teaspoon) for a lactose intolerance genetic test and a lactose challenge test*.

Visit 2: Lactose challenge test*

* You will be asked to drink 500ml of chocolate or vanilla flavoured milk (either pasteurised or UV-treated), following which we will measure your ability to digest lactose for the next 3 hours.

   In addition, you will be asked to record any symptoms of intolerance you experience for 48 hours after drinking the milk.

Those interested in being research participants should meet the following criteria;

• Be aged between 18 and 60 years

• Be apparently healthy

• Have no known food allergies or intolerances (apart from milk)

• Have no known gastrointestinal conditions

Benefits of participating in the study include;

• Information regarding your personal response to lactose in both pasteurised and UV-treated milk

• General study findings on completion of the trial.
