Insights

Infant feeding method impacts gut bacteria, affecting short-chain fatty acids (SCFA) in feces. Formula-fed infants showed different SCFA profiles compared to breast-fed infants.

Area of Science:

  • Microbiology
  • Pediatrics
  • Nutritional Science

Background:

  • Intestinal flora composition differs between breast-fed and formula-fed infants.
  • Gut microbiota differences are hypothesized to influence infant gastrointestinal health.
  • Faecal short-chain fatty acids (SCFA) profiles reflect intestinal flora variations.

Purpose of the Study:

  • To investigate and compare faecal short-chain fatty acid (SCFA) concentrations in exclusively breast-fed versus formula-fed infants.
  • To explore potential links between infant feeding practices and gut microbial metabolites.

Main Methods:

  • Faecal samples were collected from infants at two and four weeks of age.
  • Infants were categorized into exclusively breast-fed or exclusively formula-fed groups from birth.
  • Concentrations of various faecal short-chain fatty acids (SCFA), including lactate, propionic acid, and n-butyric acid, were measured.

Main Results:

  • No significant difference in total faecal SCFA concentrations was observed when lactate was included between the two feeding groups.
  • Formula-fed infants exhibited lower concentrations of lactic acid compared to breast-fed infants.
  • Formula-fed infants had higher concentrations of propionic acid and n-butyric acid than breast-fed infants.

Conclusions:

  • Infant feeding method influences the profile of faecal short-chain fatty acids (SCFA).
  • Specific SCFA, such as propionic and n-butyric acids, may be more prevalent in formula-fed infants.
  • Further research is needed to understand the implications of these SCFA differences for infant gut health, particularly regarding n-butyric acid's role.

Anatomy of the Intestines01:23

Anatomy of the Intestines

Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the small...
Development of Human Microbiota01:30

Development of Human Microbiota

The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from the skin...
Development of the Oral Microbiota01:28

Development of the Oral Microbiota

The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
Functions of the Gut Microbiota01:18

Functions of the Gut Microbiota

The gut microbiota includes trillions of microorganisms that colonize the human gastrointestinal tract, including bacteria, archaea, viruses, and fungi. This complex ecosystem plays a critical role in maintaining intestinal and systemic health. Most of these microbes inhabit the large intestine, establishing a relatively stable and diverse community that contributes to gut homeostasis through various metabolic, immunological, and protective mechanisms.Dominant bacterial phyla, such as...
Dysbiosis of the Gut Microbiota01:18

Dysbiosis of the Gut Microbiota

The human gut microbiome includes a diverse array of microbial species, including beneficial commensals and opportunistic pathogens, which interact to support host health. These microbes contribute to essential functions such as nutrient metabolism, immune system modulation, and maintenance of intestinal barrier integrity. However, disruptions to this equilibrium—referred to as dysbiosis—can have widespread physiological consequences.Dysbiosis is often characterized by reduced microbial...
Microbiota Modulation by Antibiotics01:21

Microbiota Modulation by Antibiotics

Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
