Paula Smith-Brown (University of Queensland, Australia) commenced as a research student with the Children’s Nutrition Research Centre (CNRC) in 2012. She is currently investigating the association between diet, body composition and gut microbiota in young children. Paula is a Pediatric Accredited Practicing Dietician with a specialist interest in young child nutrition and growth. She completed a BSC Nutrition and Dietetics (First Class Honours) at Kings College London, in 2002, and was awarded the Maud Taylor Prize for best overall student. She has had a diverse career including clinical, community, industry and NGO roles internationally. Paula applied for the YINI Grant in 2016 and is now working on her project until 2018.
About the study
The first 1000 days (conception to 24 months) is when gut microbiota composition and eating patterns are established, and a critical period influencing lifelong health. Maturation of the gut microbiota has been shown to be related to growth while alterations in microbiota composition are proposed to be causally related to the development of overweight and obesity. Paula’s team has shown that dairy intake at 12 months is associated with fecal microbiota and fat-free mass at 2 to 3 years. In addition, at 2 to 3 years of age, yogurt intake was strongly associated with microbiota composition.
In her new project, she hypothesizes that yogurt intake is the ideal complimentary food to promote lean and, bone mass growth and optimal microbiota development due to the combination of bioavailable branch chain amino acids and live cultures. In addition, the texture and palatability of yogurt make it a suitable food for infants. Her cross-sectional study is anticipated to provide evidence:
- To guide infant feeding advice regarding the consumption of yogurt during the period of complementary feeding with the aim of optimizing growth and microbiota development to promote long-term good health.
- Explore modulations of microbiota composition as a mechanism of action for the association between yogurt consumption and body composition during growth.
It is expected that this project will result in the publication of a minimum of 2 peer reviewed manuscripts in a pediatric nutrition-related journal by 2018-2019.
