Sauerkraut, yogurt and kombucha are all great sources of these mighty microbes. Drink more water. Water helps your body naturally remove toxins and also carries oxygen to your entire body.
A little extra hydration every day helps a lot. Get some omega-3s. Salmon, walnuts and chia seeds have omega-3 fatty acids, which reduce inflammation. These omega-3s are also perfect for construction. Foods to avoid to feel your best Limit processed foods.
No need to cut out everything unhealthy or start a strict diet. Also, it found to inhibit the production of IL-2, and IFN-γ in human peripheral blood mononuclear cells PBMCs Furthermore, piperine treatment found to reduce the production of pro-inflammatory cytokines such as IL-1β, IL-6, TNF-α, COX-2, nitric oxide synthase-2, and NF-κB in the cerebral ischemia-reperfusion-induced inflammation rat model These findings indicate the strong anti-inflammatory activity of the piperine.
Further, piperine is a potent antioxidant and protects against oxidative damage by neutralizing free radicals, ROS, and hydroxyl radicals.
It scavenges superoxide radicals with IC 50 of 1. These results indicate that piperine possesses a direct antioxidant effect against various free radicals Because of these properties, piperine can be tried as a prophylactic or therapeutic compound to protect from the oxidative stress and hyper inflammation induced during the COVID Selenium is abundantly found in common foods such as corn, garlic, onion, cabbage, broccoli.
It's an essential micronutrient that plays a vital role in various physiological processes and on the immune system. Selenium exerts its biological effect through incorporation into selenoproteins in the body.
Optimum selenium status μg per day promotes enhanced T cell proliferation, NK cell activity and innate cell functions. Further supports stronger vaccine response and robust immunity to pathogens. Also, suppresses severe inflammation in tissues such as lungs and intestine Studies have shown that selenium supplementation modulates the inflammatory response in respiratory distress syndrome patients by restoring the antioxidant status of the lungs and suppressing the IL-1β and IL-6 levels Selenium supplementation suppresses pathogen induced activation of NF-κB and its downstream pro-inflammatory cytokine release The antiviral properties of selenium have found to be mediated through its antioxidant effects.
Overall, selenium improves the immunity through its non-enzymatic role acting as cofactor for enzymes involved in critical post-translational modifications of proteins. Because of its substantial role in suppressing the inflammation and augmentation of antioxidant status and innate immunity, selenium supplementation may be useful in fight against COVID Propolis produced by honeybees and known to have a broad spectrum of biological properties, including anti-microbial, anti-inflammatory, dermatoprotective, laxative, anti-diabetic, anti-tumor, and immunomodulatory activity The immunomodulatory activity is attributed to flavonoids and some phenolic acids mainly caffeic acid phenethyl esters and artepillin C 3,5-diprenylhydroxycinnamic acid.
Propolis exhibits immunomodulatory effects on a broad spectrum of immune cells mediated by the modulation of extracellular signal-regulated kinase 2 and MAPK signaling pathways. Further, it also modulates nuclear factor of activated T cells NFAT and NF κB signaling pathways 82 , Propolis also stimulates greater antibody production, suggesting that it could be used as an adjuvant in vaccines.
Propolis at higher concentration inhibits lymphoproliferation while at low concentrations the effect is reversed, causing lymphoproliferation Further, compounds in honey propolis inhibits various viruses such as dengue virus type 2, herpes simplex virus, human cytomegalovirus, influenza virus A1 Together, with immunomodulatory and antiviral effects, propolis can be tried as a prophylactic support against COVID The commonly used probiotics are Bifidobacterium and Lactobacillus species, followed by the Streptococcus, Enterococcus, Bacillus, and Escherichia coli.
Probiotics not only support the health of the gut but also improves system functioning and regulation Though it is not clear how gut microbiome provides benefit over respiratory tract infections via gut-lung axis.
In general, it is observed that the gut microbiome impacts systemic immune responses as well as local immune responses at distal mucosal sites, including lungs Consumption of Bifidobacterium and Lactobacillus have found to help in clearing the influenza virus in the respiratory tract Levels of interferons, mucosal antibodies of lung and activity of NK cells, antigen presenting cells APCs are improved by probiotics Lactobacillus plantarum DR7 strain has shown to have suppressing effect on the pro-inflammatory cytokines TNF-α, IFN-γ, enhances anti-inflammatory cytokines IL, IL-4 and also known to reduce plasma peroxidation levels as well as modulate immune system It is reported that Lactobacillus acidophilus CMCC administration in mice infected with Staphylococcus aureus , and Pseudomonas aeruginosa decreased the damage in the lungs by reducing the bacterial load and reducing the inflammation A clinical study has reported that administration of Leuconostoc mesenteroides , Lactobacillus plantarum 2,, L.
paracasei ssp. paracasei 19, Pediococcus pentosaceus along with resistant starch, inulin prebiotics etc. reduced systemic inflammatory response syndrome and other infections Bifidobacterium longum BB strain prevents infection from influenza and improves innate immunity Though mechanism of their immunomodulating and anti-inflammatory effects in the lung are not clearly understood.
In general, probiotics exert anti-inflammatory and immunomodulatory effects via modulation of the NF-κB, MAPK and pattern recognition receptors PRR pathways that decreases Th2 mediated responses and upregulates Th1 responses. Further, they have an ability to inhibit the attachment of bacterial LPS to CD14 receptor, hence decrease in the overall activation of NF-κB and pro-inflammatory cytokines production 94 , Considering the role of probiotics in improving the host innate immune response as well as anti-inflammatory effects 87 , and considering the fact that gut involvement and enterocytes 96 can be reservoirs of SARS-CoV-2 infection, probiotics can be repurposed as prophylactics as well as adjuvants to combat the pathogenesis of COVID Lactoferrin Lf is a naturally occurring and non-toxic glycoprotein that has been studied against a broad range of viruses, including SARS-CoV, which is closely related to SARS-CoV Lf inhibits viral entry via binding to cell surface molecules or viral particles or both.
It was also known to suppress virus replication as in the case of HIV. Therefore, it plays a crucial role in preventing the virus entry and replication Studies have shown that it exerts immunomodulatory and antioxidant effects by inducing the T-cell activation, suppressing the levels of interleukins including IL-6, TNF-α, and downregulating the ferritin Also it suppresses H 2 O 2 -induced oxidative stress in human umbilical vein endothelial cells Furthermore, zinc saturated Lf exerts a more potent antiviral effect It is mainly used as a nutritional additive in infant formulas and clinical studies, with doses ranging from mg to 4.
and can be tried as a potential preventive and therapeutics against COVID Quercetin is a well-known antioxidant with anti-inflammatory and antiviral bioactive.
It inhibits TNF-α production in LPS-induced macrophages , IL-8 production in lung A cells , and mRNA levels of TNF-α and IL-1α in glial cells It also limits the production of cyclooxygenase COX and lipoxygenase LOX enzymes in rat liver epithelial cells Studies have also shown that quercetin has antiviral effects on both RNA and DNA viruses.
It inhibits the virus entry and viral-cell fusion and reduces the expression of pro-inflammatory cytokines and lung inflammation induced by rhinovirus in mice Further, quercetin metabolite 4',5-diacetyloxy-3,3',7-trimethoxyflavone has been shown to inhibit the picornavirus replication by inhibiting the RNA replicase complex Studies have also found that quercetin-3β-galactoside due to the presence of hydroxyl group, it binds to viral protease 3CL pro and inhibits its proteolytic activity Further, increased ability of estradiol in affecting human genes encoding SARS-CoV-2 targets compared to testosterone suggests a plausible explanation of the apparently higher male mortality in this corona pandemic Furthermore, as observed in prediction models that quercetin binds SARS-CoV-2 S-protein at its host receptor region or to the S-protein-human ACE2 interface interfering the virus entry into cells indicating its therapeutic potential This prediction is consistent with the reports that both quercetin and a structurally similar luteolin inhibits the SARS-CoV virus infection Additionally, other studies have also found that quercetin in combination with VC induces synergistic antiviral and immunomodulatory effects against COVID Taken together, various studies suggest that quercetin possesses potential anti-SARS-CoV-2 effects and can be repurposed as a preventive and therapeutic candidate to combat COVID Currently, there is one corona vaccine, Sputnik V, developed by the Gamaleya Research Institute, Moscow has been approved by the Ministry of Health, Russian Federation.
Presently, there are over vaccines around the world in various stages of research and development. A few of them are in human clinical trials and are being tested rigorously for their safety, efficacy, and dosage standardization.
Similarly, there are several drug candidates that have been identified and most are in various stages of research and development, whilst some of them have been repurposed and approved for emergency use in this pandemic.
The notable ones approved for use in an emergency include hydroxychloroquine, favipiravir, remdesivir, tocilizumab, etc. The plethora of existing literature provides the scientific evidence on immune-boosting, anti-inflammatory, antioxidant, and antiviral properties of several phytonutrients as summarized in Table 1.
Initial studies find that some of these have been found to possess anti-SARS-CoV-2 effects and are being fast-tracked into clinical trials Table 2. Repurposing of these nutrients in the right combination to achieve the functional synergy in the form of ready-to-eat food supplements may provide both prophylactic and adjuvant therapy against COVID Table 2.
