Turkey tail is another medicinal mushroom that has powerful effects on immune health. Research in humans indicates that turkey tail may enhance immune response, especially in people with certain types of cancer 48 , Many other medicinal mushrooms have been studied for their beneficial effects on immune health as well.

Medicinal mushroom products can be found in the form of tinctures, teas, and supplements 50 , 51 , 52 , Many types of medicinal mushrooms, including cordyceps and turkey tail, may offer immune-enhancing and antibacterial effects. According to results from scientific research, the supplements listed above may offer immune-boosting properties.

However, keep in mind that many of these potential effects these supplements have on immune health have not been thoroughly tested in humans, highlighting the need for future studies. Astragalus, garlic, curcumin, and echinacea are just some of the supplements that may offer immune-boosting properties.

Still, they have not been thoroughly tested in humans. Many supplements on the market may help improve immune health. Zinc, elderberry, and vitamins C and D are just some of the substances that have been researched for their immune-enhancing potential.

However, although these supplements may offer a small benefit for immune health, they should not and cannot be used as a replacement for a healthy lifestyle.

Aiming to eat a nutrient-dense balanced diet, getting enough sleep, engaging in regular physical activity, and not smoking or considering quitting, if you smoke are some of the most important ways to help keep your immune system healthy and reduce your chances of infection and disease.

If you decide that you want to try a supplement, speak with a healthcare professional first, as some supplements may interact with certain medications or are inappropriate for some people.

Eating a low-fat diet may also be protective. Studies have shown that limiting dietary fat helps strengthen immune defenses. Research also shows that oil may impair white blood cell function and that high-fat diets may alter the gut microbiota that aid in immunity.

Maintaining a healthy weight can also benefit the immune system. Obesity has been linked to increased risk for influenza and other infections such as pneumonia. Fiber can also lower BMI, which is linked to improved immunity.

Studies have shown that fruits and vegetables provide nutrients—like beta-carotene, vitamin C, and vitamin E—that can boost immune function. 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.

Think of proper hydration as a way to make it easier for immune-boosting nutrients to get to where they need to go cells in your body.

Immune system cells need zinc to function as they are intended. Zinc is a mineral that our body does not store or produce. While oysters have the highest food content of zinc, there are several other options such as shellfish crab, clams, lobster, and mussels , poultry chicken or turkey , red meat and beans.

Zinc is also found in fortified cereals and some breads, but the best absorption comes from animal-based foods. As you take stock of this information, consider layering the practice of mindful eating to your plan.

Mindful eating is a way to be present, focused and tuned in to the pleasure of eating. This practice can also help decrease stress which can adversely affect your immune system.

Healthy ways to cope with stress include meditating, listening to music or journaling. Physical activity is another strategy to manage stress and may reduce the risk of some chronic diseases that can weaken your immune system.

Here are some myths and facts about immune-boosting nutrients: Fact: Chicken soup can help you feel better. Myth: Vitamin C can prevent illness. Myth: Dairy increases mucus production. Choose immune-boosting nutrients These nutrients play a role in immune health: Beta carotene Beta carotene is found in plant foods, such as sweet potatoes, spinach, carrots, mangoes, broccoli and tomatoes.

Vitamin C Vitamin C-rich foods include citrus fruits, berries, melons, tomatoes, bell peppers and broccoli. Vitamin D Vitamin D is found in fatty fish and eggs. However, there are certain populations and situations in which one cannot always eat a variety of nutritious foods, or who have increased nutrient needs.

In these cases a vitamin and mineral supplement may help to fill nutritional gaps. Studies have shown that vitamin supplementation can improve immune responses in these groups. The elderly are a particularly high-risk group. The immune response generally declines with increasing age as the number and quality of immune cells decreases.

This causes a higher risk of poorer outcomes if the elderly develop chronic or acute diseases. In addition, about one-third of elderly in industrialized countries have nutrient deficiencies.

Diet variety may also be limited due to budget constraints or lower interest in cooking for one person; poor dentition; mental impairment; or lack of transportation and community resources to obtain healthy food. Megadose supplements many times the RDA do not appear justified, and can sometimes be harmful or even suppress the immune system e.

Other conditions that trigger an immune response Antigens are substances that the body labels as foreign and harmful, which triggers immune cell activity. What factors can depress our immune system? Older age: As we age, our internal organs may become less efficient; immune-related organs like the thymus or bone marrow produce less immune cells needed to fight off infections.

Aging is sometimes associated with micronutrient deficiencies, which may worsen a declining immune function. Environmental toxins smoke and other particles contributing to air pollution, excessive alcohol : These substances can impair or suppress the normal activity of immune cells.

Excess weight: Obesity is associated with low-grade chronic inflammation. Fat tissue produces adipocytokines that can promote inflammatory processes.

Chronic diseases: Autoimmune and immunodeficiency disorders attack and potentially disable immune cells. Chronic mental stress: Stress releases hormones like cortisol that suppresses inflammation inflammation is initially needed to activate immune cells and the action of white blood cells.

Lack of sleep and rest: Sleep is a time of restoration for the body , during which a type of cytokine is released that fights infection; too little sleep lowers the amount of these cytokines and other immune cells. Does an Immune-Boosting Diet Exist? Probiotic foods include kefir, yogurt with live active cultures, fermented vegetables, sauerkraut, tempeh, kombucha tea, kimchi, and miso.

Prebiotic foods include garlic, onions, leeks, asparagus, Jerusalem artichokes, dandelion greens, bananas , and seaweed. However, a more general rule is to eat a variety of fruits, vegetables , beans , and whole grains for dietary prebiotics.

Chicken soup as medicine? Is there scientific evidence that it aids in healing? But when breaking down its ingredients, it does appear a worthwhile remedy to try. Second, it provides fluids and electrolytes to prevent dehydration, which can easily occur with a fever.

Lastly, a traditional chicken soup recipe supplies various nutrients involved in the immune system: protein and zinc from the chicken, vitamin A from carrots, vitamin C from celery and onions, and antioxidants in the onions and herbs.

How much do I need? There is no specific daily recommendation for antioxidants. Should I take a supplement? Antioxidants appear to have the most benefit when you eat them in whole foods. For example, strawberries and raspberries contain an antioxidant called ellagic acid, which is poorly absorbed in supplement form.

The best antioxidant diet, one rich in fruits, vegetables and whole grains, could also be the best diet to prevent heart disease, cancer, type II diabetes, and age-related diseases.

Privacy Policy. Facebook Twitter Instagram LinkedIn Search. Boost your immune system with antioxidants. By Kristi Friesen, Registered Dietitian, Project Open Hand.

Categories: Nutrition. July 1, Antioxidants are powerful compounds in our foods that keep our immune systems working strong.

A high-fiber plant-rich diet with plenty of fruits, vegetables, whole grains, and legumes appear to support the growth and maintenance of beneficial microbes. Certain helpful microbes break down fibers into short chain fatty acids, which have been shown to stimulate immune cell activity.

These fibers are sometimes called prebiotics because they feed microbes. Therefore, a diet containing probiotic and prebiotic foods may be beneficial.

Probiotic foods contain live helpful bacteria, and prebiotic foods contain fiber and oligosaccharides that feed and maintain healthy colonies of those bacteria.

Animal studies have found that deficiencies in zinc , selenium , iron , copper, folic acid , and vitamins A , B6 , C , D , and E can alter immune responses. Epidemiological studies find that those who are poorly nourished are at greater risk of bacterial, viral, and other infections.

Eating a good quality diet, as depicted by the Healthy Eating Plate, can prevent deficiencies in these nutrients. However, there are certain populations and situations in which one cannot always eat a variety of nutritious foods, or who have increased nutrient needs.

In these cases a vitamin and mineral supplement may help to fill nutritional gaps. Studies have shown that vitamin supplementation can improve immune responses in these groups.

Annals of the American Thoracic Society. Guillin OM, Vindry C, Ohlmann T, Chavatte L. A healthful, balanced diet plays a vital role in staying well.

The following foods may help to boost the immune system:. Researchers found that people who ate foods rich in flavonoids were less likely to get an upper respiratory tract infection, or common cold, than those who did not.

Free radicals are molecules that the body produces when it breaks down food or comes into contact with pollutants. Despite its potential benefits, dark chocolate is high in calories and saturated fat, so it is important to eat it in moderation.

Turmeric is a yellow spice that many people use in cooking. It is also present in some alternative medicines. This is due to the qualities of curcumin , a compound in turmeric.

According to a review , curcumin has antioxidant and anti-inflammatory effects. Salmon, tuna, pilchards, and other oily fish are a rich source of omega-3 fatty acids. According to a report , long-term intake of omega-3 fatty acids may reduce the risk of rheumatoid arthritis RA.

RA is a chronic autoimmune condition that occurs when the immune system mistakenly attacks a healthy part of the body. Broccoli is another source of vitamin C. It also contains potent antioxidants, such as sulforaphane.

For these reasons, it is a good choice of vegetable to eat regularly to support immune system health. Sweet potatoes are rich in beta carotene , a type of antioxidant that gives the skin of the potatoes its orange color. Beta carotene is a source of vitamin A. It helps to make skin healthy and may even provide some protection against skin damage from ultraviolet UV rays.

Spinach may boost the immune system, as it contains many essential nutrients and antioxidants, including :. Vitamins C and E can help support the immune system. Research also indicates that flavonoids may help to prevent the common cold in otherwise healthy people. People use ginger in a variety of dishes and desserts, as well as in teas.

According to a review, ginger has anti-inflammatory and antioxidative properties and is likely to offer health benefits. However, more research is necessary to confirm whether or not it can effectively prevent illness.

One review looked at whether taking garlic supplements containing allicin reduced the risk of getting a cold. The group of participants taking a placebo had more than double the number of colds between them than those taking the garlic supplements.

However, the researchers concluded that more research is necessary to determine whether or not garlic can help to prevent colds. Green tea contains only a small amount of caffeine, so people can enjoy it as an alternative to black tea or coffee.

Drinking it may also strengthen the immune system. As with blueberries, green tea contains flavonoids, which may reduce the risk of a cold. Kefir is a fermented drink that contains live cultures of bacteria that are beneficial for health.

Initial research suggests that drinking kefir may boost the immune system. According to a review , various studies have shown that regular consumption of kefir can help with:. The majority of the research that supports this was carried out on animals or in a laboratory.

Researchers need to perform additional studies to understand how kefir may prevent disease in humans. Sunflower seeds can make a tasty addition to salads or breakfast bowls.

They are a rich source of vitamin E , an antioxidant. In the same way as other antioxidants, vitamin E improves immune function. It does this by fighting off free radicals, which can damage cells.

Almonds are another excellent source of vitamin E. They also contain manganese, magnesium , and fiber. A small handful or a quarter of a cup of almonds is a healthful snack that may benefit the immune system. Oranges and kiwis are an excellent source of vitamin C, which is the vitamin that many people turn to when they feel a cold developing.

While scientists are still not sure exactly how it helps, vitamin C may reduce the duration of common cold symptoms and improve the function of the human immune system. For people trying to avoid the sugar in fruit, red bell peppers are an excellent alternative source of vitamin C.

Stir-frying and roasting both preserve the nutrient content of red bell peppers better than steaming or boiling, according to a study on cooking methods. That said, it is important to remember that the immune system is complex.

Eating a healthful, balanced diet is just one way to support immune health.

Obesity has been linked to increased risk for influenza and other infections such as pneumonia. Fiber can also lower BMI, which is linked to improved immunity.

Vegetarian-based dietary patterns and their relation with inflammatory and immune biomarkers: a systematic review and meta-analysis. Adv Nutr. Rinninella E, Cintoni M, Raoul P, et al. The virus has the positive-sense RNA as its genome encoding for ~26 proteins that work together for the virus survival, replication, and spread in the host.

The virus gets transmitted through the contact of aerosol droplets from infected persons. The pathogenesis of COVID is highly complex and involves suppression of host antiviral and innate immune response, induction of oxidative stress followed by hyper inflammation described as the "cytokine storm," causing the acute lung injury, tissue fibrosis, and pneumonia.

Currently, several vaccines and drugs are being evaluated for their efficacy, safety, and for determination of doses for COVID and this requires considerable time for their validation.

Therefore, exploring the repurposing of natural compounds may provide alternatives against COVID Several nutraceuticals have a proven ability of immune-boosting, antiviral, antioxidant, anti-inflammatory effects. These include Zn, vitamin D, vitamin C, curcumin, cinnamaldehyde, probiotics, selenium, lactoferrin, quercetin, etc.

Grouping some of these phytonutrients in the right combination in the form of a food supplement may help to boost the immune system, prevent virus spread, preclude the disease progression to severe stage, and further suppress the hyper inflammation providing both prophylactic and therapeutic support against COVID
