What Is The Health Benefits Of Dietary Prebiotics – Health benefits of dietary prebiotics – Prebiotics have been an integral part of the normal human diet for many centuries.
Prebiotics are essential specific colonic nutrients that have the potential to greatly affect the physiology of the entire body and consequently health and well-being. Prebiotics specifically and selectively affect indigenous beneficial bacteria.
Prebiotics are able to convert the colonic microbiota towards a healthy structure, increasing growth, for example, while reducing cholesterol microorganisms. Some prebiotics are added to improve food quality.
And such as mouthfeel and other textual aspects.
Prebiotics have been used as low-calorie fat replicators. Breast milk can be considered a basic prebiotic for the management of the intestinal microflora in infants.
What Is The Health Benefits Of Dietary Prebiotics?
Prebiotics are an indigestible food component, actively promoting the growth and or metabolism of bacteria that promote (or improve) health in the intestinal tract and (or more) promote health.
A dietary probiotic is a selectively fermented component that allows specific changes in the structure. And or activity of the gastrointestinal microbiota, thus depending on the well-being and health of the host (Gibson et al 2004).
Health benefits of dietary prebiotics
The prebiotic is a non-digestible food component that beneficially affects the host by stimulating the growth. Activity of one or a limited number of bacteria in the colon and thus improves the health of the host.
It must be classified as a prebiotic for food ingredients.
- Neither hydrolyzed nor absorbed in the upper part of the gastrointestinal tract.
- Be a selective substrate for the colon or a limited number of beneficial bacteria, which are stimulated to grow.
- And or are metabolically active.
- As a result, being able to alter the colonic flora in favor of a healthy composition.
- Indicate luminal or systemic effects that are beneficial to the host’s health.
Symbiotics: Probiotics can be used in conjunction with growth-specific substrates (prebiotics) eg, a fructuligosaccharide with lactitol in combination with a bifidobacterial strain or a lactobacillus organism.
This combination can improve the survival of a probiotic organism in the host because its specific substrates are readily available for fermentation.
Prebiotics: Common prebiotics in use include fructooligosaccharides (FOS), galactooligosaccharides (GOS), soy oligosaccharides (SOS), inulin, lactulose, and pyredectins. Most of the studies conducted so far have focused on insulin, FOS, and GOS (Macfarlane et al 2008).
Instant Prebiotics: Emerging prebiotics include people-oligoseccharides, gluco-oligoseccharides, isomalto-oligoseccharides (IMO), lactosucros, levones, pectic-oligoseccharides, resistant starch, sugar alcohols, and xyl-oligysaccharides.
Prebiotic Mechanism of Action
- Production of short chain fatty acids during the fermentation of probiotic carbohydrates.
- Increase fecal weight and slightly lower the pH of the luminal colon.
- Fermentation of carbohydrates that promotes the growth of bacteria.
- Low concentration putrefactive, toxic, mutagenic or genotoxic substances.
- Decrease in the concentration of nitrogenous end products and reducing enzymes.
- Bifidobacteria and lactobacilli exhibit low B-glucuronidase and nitroductase activity.
- Boost immunity and improve mucus production.
Prebiotic food sources
Fructooligosaccharide (FOS) is a natural prebiotic compound found in many food sources such as artichokes, bananas, honey, onions, garlic, barley, and others.
Another prebiotic compound, inulin, is found naturally in chicory roots, wheat, onions, garlic, bananas, fruits, and vegetables.
Food sources rich in prebiotics include whole grains, honey, bananas, garlic, onions, tomatoes, leeks, artichokes, and chicory.
- Indigestible or partially digestible
- It is not absorbed in the small intestine
- Fermented by beneficial bacteria in the gut and
- Selective stimulation of intestinal bacterial growth and activity.
Metabolic fate of prebiotics
Inulin and oligofructose do not hydrolyze in the mouth, stomach, and small intestine. In the large intestine, they undergo complete anaerobic fermentation by bacteria. They do not contribute to calories.
They are completely fermented in the colon, so insulin is not excreted in the stool.
Prebiotics and dietary fiber
Prebiotics and dietary fiber are not digested by human digestive enzymes, but prebiotics are fermented in the colon and enhance their health effects through the colonic microbiota.
Dietary fiber, on the other hand, cannot be fermented at all and can have health effects in other ways for better bowel function, for example.
Colonic microbial system
The colonic microbial system consists of a wide range of bacterial species, a variety of different metabolic niches, bacterial habitats, and interrelationships.
Bacteria in the normal intestines can be divided into species that have harmful or beneficial effects on the host.
The pathogenic or harmful effects include diarrhea, infection, liver damage, carcinogenesis and intestinal disorders; The health-promoting effects may be due to the growth of harmful bacteria.
The stimulation of immune functions, the reduction of gas deformity problems. The improvement of the digestion and absorption of essential nutrients and the synthesis of vitamins.
Health-promoting functions of bifidobacteria
Bifidobacterium is an important group of saprolytic bacteria in the colon and constitutes 25% of the total population in the adult intestine and 95% in newborns (Kavrez et al 1981).
Bifidobacteria produce strong acids as end products of metabolism (acetate, lactate), lower the pH, and can exert an antibacterial effect. Bifidobacteria produce group B vitamins.
Bifidobacteria produce some immunomodulators that promote immune attack on malignant cells. Bifidobacteria have been used to restore normal intestinal flora during antibiotic therapy (Korshonov et al 1985).
Health benefits of dietary prebiotics
- Increase the absorption of dietary minerals such as calcium, magnesium and iron.
- Reduce the risk of stomach cancer.
- Reduce cholesterol and blood lipids.
- Prevent the infection of the gastrointestinal tract.
Increase the growth of bifidobacteria, whose beneficial effects are the following:
- Group B produces nutrients such as vitamins and folic acid.
- Produces digestive enzymes.
- Reduces food intolerance through the use of residual nutrients from the upper intestine.
- Improves nutrient management.
- The liver reduces toxins, that is, blood amines and ammonia, using them as fuel.
- Competitive eradication of pathogenic microorganisms.
Prebiotics are indigestible foods. They are selectively fermented by intestinal bacteria (eg, lactobacilli, bifidobacteria).
Possible health benefits of prebiotics include increased bioavailability of dietary minerals and a decreased risk of various diseases such as cancer, intestinal infections, cardiovascular disorders, obesity, and diabetes.
Prebiotics are naturally available in many foods, including whole grains, onions, garlic, bananas, fruits, and vegetables. Dietary Prebiotics can improve sleep and prevent the fight against stress by affecting intestinal bacteria: studies.
Dietary Prebiotics can improve sleep and increase the flexibility of stress by affecting intestinal bacteria and metabolites (biologically active molecules). According to a new study in mice published in scientific reports.
Ingestion of prebiotic diets improves negative NREM sleep, promotes rebound of REM sleep after exposure to stress and prevents stress-induced reductions in intestinal microbial alpha diversity.
Most people are familiar with probiotics.
The friendly bacteria present in fermented foods such as yogurt and sauerkraut.
Ingestion of a prebiotic diet improves negative NREM sleep, promoting the rebound of REM sleep after exposure to stress and inhibits stress-induced reductions in intestinal microbial alpha diversity.
Recently, scientists have been interested in prebiotics, dietary compounds that humans cannot digest. But that serve as trunks of our microbiome or the bacteria that live within us.
While not all fibers are prebiotic, many fibrous foods such as leeks, artichokes, onions and certain whole grains are rich in them.
Postdoctoral researcher in the Department of Integrative Physiology at the University of Colorado Boulder, Drs. Robert Thompson said: The biggest path here is that this type of fiber is not just to accumulate feces and pass through the digestive system.
It’s creating insects that live in our stomachs and forming a symbiotic relationship with us that has powerful effects on our brain and behavior.
For the study, Drs. Thompson and his colleagues began juvenile male mice with prebiotics in standard chow or chow and tracked a series of physiological measures before and after the mice were stressed.
As reported in a previous study by the team, those with a prebiotic diet spent more time in a non-restorative sleep of rapid eye movement (NREM). After stress, they spent more time in rapid eye movements (REM).
Which is considered important for overcoming stress.
While mice that eat normal food had observed natural body temperature fluctuations and a decrease in the healthy diversity of their gut microbiomes after stress. Those fed with prebiotics were cushioned by these effects.
The new study sheds light on how prebiotics can relieve bust stress.
We know that this combination of dietary fiber helps strengthen stress and promote good sleep and protects the intestinal microorganism from disruption, said Professor Monica Fleischner, director of the Stress Physiology Laboratory at the University of Colorado Boulder.
With this new study, we wanted to try to identify the signal. The researchers measured the metabolites, using a technique called mass spectrometry to analyze stool samples from mice.
They discovered that mice in the prebiotic diet had a different ‘metabolism’, or metabolite composition. It was high in dozens of them, including fatty acids, sugars and steroids. Which can affect behavior through the intestine-brain signaling pathway.
It looked different even after stress. For example, mice with the standard Chow diet saw dramatic peaks in the alloprenanolone precursors and ketone steroids, presumably metabolites that disturb sleep.
While those in the prebiotic diet did not see that peak. Our results reveal new signals that come from intestinal microbes that can regulate the physiology of stress and sleep, said Professor Fleshner. While prebiotic dietary fiber is certainly healthy.
It is unclear whether loading only rich foods can promote sleep. The rats were fed very high doses of four specific prebiotics. Which include: galactuligosaccharides, which are present in lentils and cabbage.
Polydextrose (PDX) is an FDA-approved food additive that is often used as a sweetener; Lactoferrin is found in breast milk. And spherical proteins rich in milk fats, abundant in dairy products.
You can probably eat a lot of lentils and cabbage to see any effect, said Dr. Thompson said.
Prebiotic supplements are already abundant on the shelves of health food stores. But he also said that it is too early to say whether a supplement or a medicine containing such compounds will be safe and effective for everyone.
Depending on their microbial composition, different people may react differently. These are powerful molecules with real neuroactive effects and people should be a little careful.
