TuMMI trial

Does treating milk with heat affect how it is digested? We're looking for healthy women to help us find out.

What is the aim of this study?

TuMMI stands for 'Temperature treatment of Milk impacts on MRI digestion rates and nutrient delivery'. It's a study that's trying to find out whether treating milk with heat affects how it is digested. We're looking for healthy female volunteers aged 18-40 to take part.

Please note this study is currently postponed due to COVID-19.

Who can take part?

We're looking for:

  • women aged 18-40 years
  • with a BMI 18-28 kg/m2
  • who are regular milk drinkers
  • and willing to have MRI scans and give blood

What is involved?

If you take part in the study, you'll need to come into the Liggins Institute (opposite Auckland City Hospital in Grafton) on two separate mornings to drink either pasteurised or ultra-high temperature treated (UHT) milk.

We will take an Magnetic Resonance Imaging (MRI) scan to measure your stomach contents after drinking, and we'll take blood samples from an arm vein at intervals for five hours. We'll also measure breath and urine samples.

By taking part you'll learn more about your own digestive responses and help us to better understand the digestibility of different milks.

You'll also be compensated for your time and effort for these two study visits.
