Prebiotics for enhanced immune function -

Health conditions such as stress 1 , 2 , obesity 3 , and aging 4 will diminish immune responses. Severe respiratory tract infections may be caused by bacteria and viruses such as influenza 2.

Nonetheless, the risk and severity of enteritis and ventilator-associated pneumonia are reduced with beneficial changes to the gut microbiota, while probiotics can also reduce side-effects of antibiotics that may be used to treat respiratory infections 5.

Azad et al. Nishihira et al. Other studies suggest a role for probiotics and prebiotics for modulation of the microbial community, supporting the digestive and immune systems.

The mucosal system protects the gastrointestinal tract, urogenital tract respiratory tract, and oral-pharyngeal cavity, and has similar features and structures within these different regions of the body 6. The mucosal epithelial layer, coupled with innate and adaptive immune responses, helps to protect against pathogenic bacteria and viruses.

The gut-associated lymphoid tissue GALT responds to antigens within the lumen, and GALT histology and function are affected by diet 7. Cytokines control the growth and activity of immune cells and affect the growth of blood cells that support immune and inflammatory responses within the body.

Chemokines are a particular type of cytokine that direct immune cells towards a target. Examples of chemokines include growth factors, interferons, interleukins ILs and tumor necrosis factors TNF.

These may mediate immune responses, and may also play a role in inflammation, which may have beneficial or adverse effects. Antibodies such as immunoglobulins play an important role in protecting against disease and infection. Antibodies will bind to particular antigens, triggering a response by other immune cells.

Immunoglobulin A IgA is mainly found in and secreted by mucosal tissues. IgA thus plays an important role in immune function within the intestine and respiratory tract.

Other immunoglobulins include IgM, IgE and IgD. IgM responds quickly to infections, triggering other antibodies and immune cells such as IgG into action. Other cells that influence immune and inflammatory responses to pathogens include Natural Killer NK cells and Natural Killer T NKT cells 8 , along with up-regulation of IL anti-inflammatory and TNF-alpha proinflammatory cells 6.

infections and injuries to tissue cause IL-6 to be produced by monocytes and macrophages. Hepatocytes and immune competent cells are activated by IL6 to promote healing and removal of infectious agents. However, overexpression of IL-6 can lead to chronic inflammation and acute complications 9.

General Impacts. Probiotics and prebiotics can modify the gut microbial community, affecting the immune response within the body, supporting innate immunity and antipathogenic activity. Orally administered probiotics support immune function by directly or indirectly interacting with the host immune system 10 , However, the ability to modulate the human immune system is not universal.

Impacts on the immune system, if present, are dependent upon the strain of probiotic, and metabolites produced by the probiotic or microbes induced by the probiotic 12 , Several probiotics have been reported to decrease proinflammatory chemokine responses in epithelial cells.

However, the strain of probiotic may affect chemokine responses; the expression of certain chemokines may be reduced while others may be promoted, depending upon the strain 8.

Lymphocytes are affected by short chain fatty acids produced by microbial metabolism either from probiotics or commensal microbes induced by prebiotic consumption 8. Some species of probiotics improve mucosal barrier function Lacticaseibacillus casei and Bifidobacterium adolescentis produce metabolites that limit expression of viral and bacterial toxins that disrupt the function and structure of tight barrier junctions during infection.

Consequently, these probiotics maintain barrier function and permeability. Probiotics can trigger the release of cytokines and chemokines, e. interleukins IL , lymphocytes, tumor necrosis factor TNF , transforming growth factor TGF , interferons, mast cells, dendritic cells and macrophages 2 , 6.

For example, type 1 interferon IFN production and NK cell activity can be stimulated following consumption of lactic acid bacteria LAB 15 , 16 , Lehtoranta et al.

Similarly, increased natural killer cell activity and cytotoxic activity has been observed following consumption of select probiotics A review of six randomized placebo-controlled clinical trials by Gui et al. Certain metabolites can stimulate the release of pro- and anti-inflammatory cytokines and molecules recognized by toll-like receptors in the intestine and by the immune system 21 , 22 , The reduction in pH by organic acid metabolites from Lactobacilli and primary metabolites such as hydrogen peroxide may lead to direct virucidal effects Metabolites produced by probiotics and commensal bacteria stimulated by prebiotics may thus have an important role in the immune response to infections.

Some probiotics may have a more direct effect on the immune response. However, it should be noted that nutritional fibers and their impact on human health have been well-established for many years.

The review also affirmed that dietary fiber controls viral infections and chronic diseases. Diets high in fiber have been shown to have protective effects against type 2 diabetes, cardiovascular diseases and obesity.

These short-chain fatty acids help prevent the development of type 2 diabetes. Meanwhile, beta-glucans in dietary fibers have been linked to reducing low-density lipoprotein and total cholesterol.

In addition, nutritional fibers help prevent cardiovascular diseases by controlling or preventing obesity. Once ingested, these dietary fibers increase feelings of satiety since their transit time to the lumen of the intestine is prolonged.

In contrast, digestible and simple polysaccharides in sugar-rich food are easily digested. This leads to increased feelings of hunger compared to eating food rich in fiber. Another mechanism related to dietary fibers in preventing obesity involves its low energy bulk, which in turn could influence the palatability of the foods.

In turn, this can lead to a lower intake of calories. In contrast, eating a diet high in saturated fats and sugar, animal meat proteins and processed foods, which often represent the western diet, results in less diverse-gut bacteria.

This increases the risk of chronic diseases since this diet promotes inflammation. In addition, diets high in saturated fats increase the risk of obesity.

Current studies show that fat cells secrete chemicals and hormones known to increase inflammation. Hence, fatty tissues are now recognized as metabolically active endocrine organs. Being overweight or obese affects immune function.

Obesity stimulates low-grade inflammation, which is an immune system response. Eating a plant-based diet and maintaining a healthy weight is critical in boosting the immune system and maintaining healthy microbiota. Considering the importance of prebiotics in boosting a healthy immune system by maintaining a healthy gut, here are some excellent sources of prebiotics:.

Prebiotic supplements are also excellent sources of food for microorganisms. Keep in mind that there are many prebiotics supplements. Always consult your doctor when planning to take prebiotics supplements to boost your immune system and improve your gut health.

The type of bacteria and the amount present in supplements vary by brand. Hence, it is essential to always do your research when planning to take these supplements. You can talk to your doctor to determine which prebiotics supplement works best for your current health condition.

Prebiotics serve as essential food sources for bacteria present in the gut. The best sources of prebiotics include vegetables and fruits. In contrast, a western diet high in saturated fats, sugar and animal meat has been associated with inflammation and the development of chronic diseases.

Since the diversity and health of the microorganisms are intertwined with the optimal functioning of the immune system, it is best to eat foods rich in prebiotics to boost the health of the microbiota.

Apart from naturally occurring prebiotics, supplements are also good sources of prebiotics. Like any supplement, always consult your doctor before deciding which prebiotic supplement to take.
