About this study

Breastfeeding is recommended for babies from birth to six months old because breast milk provides all the nutrients babies need for growth and development. Breast milk contains sugars called oligosaccharides, which support the development of a healthy gut in babies. The foods that breastfeeding mothers eat might influence the sugars in their breast milk and the natural, friendly bacteria inside their babies' gut-called the gut microbiota-which are important for overall health. Fibre-rich foods like fruits, vegetables, whole grains, beans, and nuts, as well as fermented foods like yogurt and milk kefir, support a healthy gut. The main aim of this study is to find out whether eating foods rich in fibre and fermented foods by breastfeeding mothers can affect the bacteria residing in the gut of their breastfed babies. The study will also explore how this diet affects the mother's gut microbiota, breast milk composition, and gastrointestinal (GI) symptoms for both mothers and babies. The main question of the study is: Does a 2-week diet high in fibre and fermented foods consumed by breastfeeding mothers affect the gut microbiota of their breastfed babies aged 2 to 5 months, compared to mothers following their habitual diet? Participants will: * Be randomly assigned to one of two groups: (1) one group will follow a specific diet high in fibre and fermented foods (25 g of fibre/day + 3 servings of fermented foods/day) in addition to their habitual diet, or (2) the second group w…
