Introduction to the Human Microbiota01:22

Introduction to the Human Microbiota

27
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity,...

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...

Probiotics01:22

Probiotics

3
Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...

Development of the Oral Microbiota

9
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

2
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...

Microbiota of the Large Intestine01:27

Microbiota of the Large Intestine

1
The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...

Area of Science:

  • Nutritional Science
  • Microbiology
  • Human Health

Background:

  • Nut consumption is linked to positive human health outcomes.
  • Benefits are often attributed to fatty acids, protein, fiber, and micronutrients.
  • Emerging research highlights the role of non-bioaccessible nut components.

Purpose of the Study:

  • To review the prebiotic properties of non-bioaccessible nut materials in humans.
  • To explore the role of these materials in gut microbiota modulation.
  • To investigate the formation of new bioactive metabolites and their absorption.

Main Methods:

  • Literature review focusing on human studies.
  • Analysis of research on polymerized polyphenols and polysaccharides in nuts.
  • Examination of gut microbiota interactions and metabolite production.

Main Results:

  • Non-bioaccessible nut components (polyphenols, polysaccharides) act as prebiotics.
  • These components provide substrates for human gut microbiota.
  • Gut microbiota metabolize these compounds into new bioactive substances.

Conclusions:

  • The prebiotic effects of nuts contribute significantly to their health benefits.
  • Modulation of gut microbiota by nut components is a key mechanism.
  • Further research into nut-derived metabolites and their absorption is warranted.
