Know your biotics1
- Probiotics are naturally occurring friendly bacteria that affect the gut microbiota when ingested
- Prebiotics are non-digestible carbohydrates that pass intact through the upper part of the gut and stimulate the growth or activity of friendly bacteria
- Postbiotics are bioactive components produced by the metabolic activity of probiotic bacteria, which have an important role in the regulation of biologic activity in the gut
Building immunity from the start
The gut and immune system develop rapidly throughout the first 1,000 days, as babies move from a protected environment to one where they are exposed to lots of immune challenges. Nutrition plays a significant role in influencing the gut microbiota, shaping the development of both the gut and the immune system5. From birth, microbes in the gut perform essential duties6:
- The digestion and metabolism of food
- The production of neurotransmitters that affect behaviour and cognitive function. The gut microbiota exerts influence over anxiety, mood, sociability and cognition
- The development and activation of the immune system. The gut is the centre of the immune system – 70-80% of the body’s immune cells are in the gut7
Supporting the maturation, diversity and condition of the gut microbiota through optimal nutrition in the first 1,000 days is fundamental for the development of a healthy immune system8,9, protecting against harmful bacteria, reducing risk of disease, and safeguarding future health5.
Prebiotic power
Breastmilk is the best form of nutrition for babies, containing all of the nutrients required to support a baby’s healthy growth and development in the first six months (see figure 110,11).
In early infancy, nutrition greatly influences the composition of the gut microbiota, and in turn, the emerging immune system5,12,13. The composition of breastmilk is complex; it helps to strengthen baby’s developing immune system by providing protective bioactive elements such as prebiotic oligosaccharides, live bacteria and metabolites14,15. These prebiotic oligosaccharides help to positively shape the infant’s gut microbiota, promoting the growth of beneficial or ‘friendly’ bacteria (e.g: bifidobacteria and lactobacilli)8,16-18.
Prebiotics are non-digestible carbohydrates. They travel to the gut intact and are fermented by the friendly bacteria that reside there18. Postbiotics are produced by this natural fermentation process in the gut, including short-chain fatty acids (SCFAs)19, which help to maintain the gut barrier and have been shown to influence immune function5.
Pioneering prebiotic research
Inspired by over 40 years of breastmilk research, Nutricia Early Life Nutrition was the first company to introduce a blend of short-chain prebiotic galacto-oligosaccharides and long-chain fructo-oligosaccharides (scGOS/lcFOS) into infant formula. Like naturally occurring prebiotic oligosaccharides in breastmilk, the scGOS/lcFOS (9:1) prebiotic mixture are not digested by the infant’s digestive enzymes and instead selectively stimulates growth and activity of friendly bacteria in the gut.16,20
Nutricia Research has conducted more than 30 clinical studies to evaluate the benefits of scGOS/lcFOS (9:1). These studies have shown that the addition of this unique prebiotic mixture stimulates a bifidogenic gut microbiota21, closer to the composition found in breastfed babies, to support the development of a healthy immune system16,18,22, and brings stool consistency and defaecation frequency closer to those of breastfed infants.18,23,24
Benefits for baby of prebiotics in infant formula
The prebiotic mixture scGOS/lcFOS (9:1) has been proven to:
- Increase levels of friendly gut bacteria and reduce levels of potentially harmful bacteria
- Improve stool frequency and consistency18,23,24
- Reduce occurrence of infections requiring antibiotics20,27
- Reduce incidence of allergic symptoms, such as atopic dermatitis27,28
