Remember to drink adequate fluids throughout the day. Plain water is best. Good hygiene and hand-washing help prevent the spread of germs. Remember to wash produce before eating or using it in recipes.

Clean glasses, forks, spoons and other utensils to reduce the spread and growth of bacteria. Getting adequate sleep and managing stress can be just as important as healthy eating to prevent the flu. Even if you eat healthily, get plenty of rest, drink adequate fluids and manage your stress, you may still catch the flu.

If so, your illness may not last as long, and you may not feel so bad. According to the National Institutes of Health, there are many healing benefits of chicken soup.

Your favorite recipe likely has properties that fight inflammation, promote hydration and get mucus flowing. Drink plenty of liquids, such as water, broth or sports drinks with electrolytes. When taken before cold symptoms start, vitamin C may shorten the duration, but it doesn't keep you from getting sick.

You may have heard that milk and other dairy products worsen congestion during an illness. Research has not proven this to be true. Bring broth to a boil in a Dutch oven. Add carrots, celery, ginger and garlic; cook uncovered over medium heat until vegetables are just tender, about 20 minutes.

Because many vegetables, fruits, and other plant-based foods are also rich in antioxidants, they help reduce oxidative stress. Beta-Carotene: Beta-carotene is a powerful antioxidant that can reduce inflammation and boost immune function by increasing disease-fighting cells in the body.

Excellent sources include sweet potatoes, carrots, and green leafy vegetables. Sources of vitamin C include red peppers, oranges, strawberries, broccoli, mangoes, lemons, and other fruits and vegetables.

Vitamin E sources include nuts, seeds, spinach, and broccoli. Vitamin D: Research shows vitamin D supplementation may reduce the risk for viral infections, including respiratory tract infections, by reducing production of proinflammatory compounds in the body.

Increased vitamin D in the blood has been linked to prevention of other chronic diseases including tuberculosis, hepatitis, and cardiovascular disease. Food sources of vitamin D include fortified cereals and plant-based milks and supplements.

Zinc: Zinc is a mineral that can help boost white blood cells, which defend against invaders. Sources include nuts, pumpkin seeds, sesame seeds, beans, and lentils.

Our bodies need sleep to rest and recharge. Inadequate sleep has also been linked to suppressed immune function. One study found that those who sleep fewer than five hours per night are more likely to have recently suffered a recent cold compared with those who sleep more.

In fact, your life depends on the intake of certain antioxidants — namely, vitamins C and E. However, many other non-essential antioxidants occur in food. The health benefits associated with a diet rich in plants is at least partially due to the variety of antioxidants they provide Berries, green tea , coffee, and dark chocolate are renowned for being good sources of antioxidants Meat products and fish also contain antioxidants, but to a lesser extent than fruits and vegetables 15 , Antioxidants can increase the shelf life of both natural and processed foods.

For instance, vitamin C is often added to processed foods to act as a preservative Your diet is an essential source of antioxidants, which are found in animal and plant foods — especially vegetables, fruits, and berries. Water-soluble antioxidants perform their actions in the fluid inside and outside cells, whereas fat-soluble ones act primarily in cell membranes.

Notable examples include curcuminoids in turmeric and oleocanthal in extra virgin olive oil. These substances function as antioxidants but also have potent anti-inflammatory activity 19 , Some studies even show that high doses of antioxidants increase your risk of death 23 , For this reason, most health professionals advise people to avoid high-dose antioxidant supplements , although further studies are needed before solid conclusions can be reached.

Eating plenty of antioxidant-rich whole food is a much better idea. Studies indicate that foods reduce oxidative damage to a greater extent than supplements. For example, one study compared the effects of drinking blood-orange juice and sugar water, both of which contained equal amounts of vitamin C.

It found that the juice had significantly greater antioxidant power The best strategy to ensure adequate antioxidant intake is to follow a diet rich in various vegetables and fruits, alongside other healthy habits However, low-dose supplements, such as multivitamins, may be beneficial if you are deficient in certain nutrients or unable to follow a healthy diet.

Studies suggest that taking regular, high-dose antioxidant supplements may be harmful. If possible, get your daily dose of antioxidants from whole foods, such as fruits and vegetables.

Adequate antioxidant intake is essential to a healthy diet, although some studies suggest that high-dose supplements may be harmful. The best strategy is to get your daily dose of antioxidants from healthy plant foods, such as fruits and vegetables.

Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

Coffee is incredibly high in antioxidants. Several studies have shown that people get more antioxidants from coffee than any other food group. Antioxidant supplements are popular, but evidence suggests that they have several drawbacks.

This article explains what antioxidant supplements are….

It's ijmune season again, so Antioxidants and immune system support people get Anioxidants flu shot and strive to stay immunf. But supoprt certain foods or supplements boost the Suppoft system and help with that "staying healthy" strategies to improve wakefulness Don't skip meals, so your body stays well-fueled. Aim for five to nine servings of vegetables and fruits daily to provide those immune-boosting vitamins, minerals and antioxidants. Getting these nutrients from foods versus vitamin or mineral supplements is always best. Many herbal remedies are marketed to help fight colds or shorten their duration, but check with a health care professional before taking any supplements or medications. New research shows systsm risk of infection from prostate biopsies. Antioxidants and immune system support at Antioxicants is linked to high blood pressure. Anrioxidants fingers and toes: Poor circulation or Raynaud's Conditioning drills for athletes Some Anitoxidants and minerals — Immkne vitamins C and E and the minerals copper, zinc, and selenium — serve as antioxidants, in addition to other vital roles. Because free radicals lack a full complement of electrons, they steal electrons from other molecules and damage those molecules in the process. Antioxidants neutralize free radicals by giving up some of their own electrons. In making this sacrifice, they act as a natural "off" switch for the free radicals.

Se in the metalloenzyme glutathione peroxidase EC 1. Numerous epidemiological studies have found strong associations between diets rich in antioxidant nutrients and a reduced incidence of cancer, and it has been suggested that a boost to the body's immune system by antioxidants might, at least in part, account for this.

Although more striking effects have been observed in the elderly, there is also evidence that antioxidant nutrients can modify cell-mediated immune responses in younger individuals. Indeed, it might be essential to have an adequate intake of antioxidant nutrients from an early age in order to help prevent the development of, or at least delay the onset of, several degenerative disorders.

The present paper will review the effects of specific nutrients on immune function in young to middle-aged human subjects, focusing on the antioxidant vitamins C and E, and on Se. A further review, dealing more specifically with the effects of carotenoids on human immune function, will be presented at a forthcoming meeting of the Nutrition Society.

Abstract The immune system is highly reliant on accurate cell-cell communication for optimal function, and any damage to the signalling systems involved will result in an impaired immune responsiveness. 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.

Exposure to UV light, Antioxidantts smoke, and other environmental pollutants also increases the body's free radical burden. The harmful activities of free radicals are associated with damage to membranes, enzymes, and DNA. The ability of antioxidants to destroy free radicals protects the structural integrity of cells and tissues. This review focuses on data indicating that the functions of the human immune system depend on the intake of micronutrients, which can act as antioxidants. Recent clinical trials have found that antioxidant supplementation can significantly improve certain immune responses.
