About this study
It is well known that breastmilk contains a host of nutritive, protective and beneficial components. However, it is not so widely known that these components are highly variable and are influenced by all sorts of environmental and personal factors, including maternal diet.
Infants’ nutrition can have life-lasting impacts on their health and we feel it is important for mothers, families and health care professionals to be knowledgeable about the variability of breast milk so that they can make better informed choices during this important time.
Exploring the influence maternal diet has on breast milk is one way for us to further the positive influence of breastfeeding by better understanding its idiosyncrasies. Our research aims to measure the compositional changes that occur in breast milk in real-time whilst mothers consume different diets so that we can get a really good look at how diet affects breast milk.
We are conducting a clinical trial which will occur over a two day period. We will provide mothers with two separate diets over two days; one standardised healthy diet and one with slightly higher sugar/fat content. All food will be supplied and prepared over breakfast, lunch, dinner and snacks. Over the two days we will ask you to express small amounts of breastmilk at specific times.
This trial has been designed with mum and baby's best interests in mind and we aim to make the interventions minimally disruptive.
This study has been designed based on an almost identical 'pilot' study which was conducted in the UK in 2019.
Who can participate in the study?
- Healthy mothers and singleton infants born at full term
- Mothers between the ages of 21-35 years
- Mothers with a Body Mass Index (BMI) between 20 and 30 kg/m2
- Infants between 6 and 20 weeks of age at the time of recruitment
- Mother and infants have no self-reported underlying medical conditions/special dietary requirements which result in restriction of any major food groups (e.g. vegan/dairy allergy)
- Mothers able to give informed consent for themselves and their infants
- Mothers have been exclusively breastfeeding (with the exception of additional water or medication such as paracetamol suspensions) their infant since birth
- Infants who are fed formula milk or fed a mixture of breast milk and formula
- Mothers who are struggling with breast feeding and/or are unable to manually express milk.
- Mother and/or baby who has an allergy/intolerance/aversion to the study diet (e.g. lactose intolerance).
