The 10 Tastiest Ways to Eat More Kale—Even if You're Over Kale Salad. Here's why I consider it a top food to support immune health: a 4-ounce serving of flank steak provides more than half of the Recommended Dietary Allowance RDA for zinc, selenium, and vitamin B6.
Getting adequate intake of these three nutrients can be challenging, and a slight deficiency of any may impair your immune system from working at percent efficiency. This can increase your susceptibility to illness and lower your immune defense capacity.
Look for ways to incorporate lean cuts of beef like sirloin , round steak , and flank steak up to three times per week. Vitamin A is considered essential to normal immune functioning, and leafy greens like spinach are packed with beta-carotene, a form of vitamin A that is also an antioxidant.
On top of that, leafy greens are a good source of folate, and some research suggests that a deficiency may impair immune response. Not a fan of spinach? Most dark-green and orange vegetables are good sources of beta-carotene while folate is also in fruit, beans, nuts, and whole and fortified grains.
Immunity-boosting isn't a health perk often associated with salmon , but adequate and regular intake of omega-3s particularly DHA and EPA, which are two forms found in cold-water fish are key for tamping down inflammation.
This, in turn, allows the immune system to focus more of its attention on defending the body against pathogens and fighting illness.
Need a shelf-stable option? Stock the pantry with cans of salmon or light tuna in water. Both fish are also good sources of vitamin D and the antioxidant mineral selenium, two nutrients that also support immune health.
Consuming yogurt with minimal added sugar and "active, live cultures" is an easy way to support immune health. Yogurt's benefits come from the probiotics , or good bacteria, because research suggests the immune system and microbiome work with one another to target pathogens and to fine-tune immune responses.
This means having an imbalance of good bacteria could potentially impact immune response effectiveness. Incorporate yogurt and other probiotic-rich foods to strengthen your microbiome, decrease gut permeability, and support immune function. It seems far-fetched that chicken soup could really do much for your health, but our grandmothers may have been on to something.
Research suggests that eating chicken soup has a mild anti-inflammatory effect that impacts white blood cells. This could lead to a decreased risk of developing a respiratory infection, something that may be due to a compound in chicken that inhibits viral infections according to another study.
While immune protection from chicken soup is definitely speculative, incorporating a bowl of chicken soup doesn't hurt and may offer more benefit over other hot liquids thanks to the protein, garlic, and onions. Another perk: making a large batch of soup saves time in the kitchen and is great to have around, particularly when working from home.
Some foods can also impede your immune system from functioning at its best. Here are three to avoid or limit to minimize the negative impact they can potentially have on your body's health.
A lack of adequate, good quality sleep impairs your body's immune response, increasing one's susceptibility to illness and decreasing immune defenses. And even if caffeine doesn't keep you from going to sleep, consuming more than three caffeinated drinks a day can prevent the body from spending adequate time in that deep, restorative sleep phase.
To minimize these effects, limit caffeinated drinks to no more than two to three per day, and consume them during the first half of the day. Any of these can irritate the body and exacerbate existing inflammation. It also contains amino acids that may aid in the production of germ-fighting compounds in your T-cells, which reduces inflammation in the body and helps fight infection.
Green tea can be consumed hot, cold or as matcha powder. Vitamin D can be found in salmon, canned tuna, egg yolks, and mushrooms. Your body can also synthesize vitamin D with just minutes of sunshine three times a week. Yogurt, Kombucha, Sauerkraut, Kimchi, Pickles, Tempeh Fermented Soybeans , and certain types of cheese contain live cultures, also known as probiotics, which are thought to help stimulate the immune system to fight off disease.
The microbiome helps you process the nutrients described throughout the rest of this article, while also acting as an extra barrier for fighting off harmful bacteria and fungi. Garlic contains compounds that help the immune system fight germs in a variety of ways by stimulating cells important to fighting disease and helping to regulate the immune system.
It helps boost the production of virus-fighting T-cells and can reduce the amount of stress hormones your body produces which can help keep your immune system functioning at full strength. Vitamin B-6 is essential in the formation of new and healthy red blood cells, and aids in maintaining the lymphatic system.
Chicken, turkey, cold-water fish salmon and tuna , chickpeas traditional hummus , bananas, fortified breakfast cereal, and nutritional yeast are great options for consuming vitamin B Water helps produce lymph which carries white blood cells and other immune system cells through the body.
There are many foods with high water content such as cucumbers, watermelon, and celery. If you have a hard time drinking plain water, try a cup of green tea with lemon, watermelon, cucumber or mint-infused water for an immune system powerhouse beverage.
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.

When foodd comes Immunkty-boosting preventing and fighting off colds, vitamin E tends to take a backseat to vitamin C. However, this powerful antioxidant is key to a healthy immune system. Nuts, such as almondsare packed with the vitamin and also have healthy fats.
Adults only need about 15 mg of vitamin E each day. Sunflower seeds are full of nutrients, including phosphorousmagnesiumand vitamins B6 and E. Vitamin E is important in regulating and maintaining immune system function. Other foods with high amounts of vitamin E include avocados and dark leafy greens.
Sunflower seeds are also high in selenium. Just 1 ounce contains nearly half the selenium that the average adult needs daily. A variety of studiesmostly performed on animals, have looked at its potential to combat viral infections such as swine flu H1N1. You may know turmeric as a key ingredient in many curries.
This bright yellow, bitter spice has also been used for years as an anti-inflammatory in treating both osteoarthritis and rheumatoid arthritis. Research shows that high concentrations of curcuminwhich gives turmeric its distinctive color, can help decrease exercise-induced muscle damage.
Curcumin has promise as an immune booster based on findings from animal studies with antimicrobial properties. More research is needed. Both green and black teas are packed with flavonoidsa type of antioxidant. Where green tea really excels is in its levels of epigallocatechin gallate EGCGanother powerful antioxidant.
Research has suggested that EGCG may have antiviral properties that support the immune system. The fermentation process black tea goes through destroys a lot of the EGCG. Green tea, on the other hand, is steamed and not fermented, so the EGCG is preserved.
Papayas also have a digestive enzyme called papain that has anti-inflammatory effects. Papayas have decent amounts of potassiummagnesium, and folateall of which are beneficial to your overall health.
Like papayas, kiwis are a rich source of essential nutrients, including folate, potassium, vitamin Kand vitamin C.
The soup may help lower inflammation, which could improve symptoms of Immunuty-boosting cold. Poultry, such as chicken and turkey, is high in vitamin B6. About 3 ounces of light turkey or chicken meat contains nearly one-third of your daily recommended amount of B6.
Vitamin B6 is an important player in many of the chemical reactions that happen in the body. Stock or broth made by boiling chicken bones contains gelatinchondroitin, and other nutrients helpful for gut healing and immunity. Too much zinc can actually inhibit immune system function.
You may want to focus on eating a balanced diet with plenty of fresh foods and whole grains, engage in at least minutes of physical activity per week, get enough sleep, manage stress with deep breathing or talk therapy, avoid or quit smoking, and limit alcohol consumption.
Preliminary research suggests vitamin C may be involved in the development and function of white blood cells. It seems vitamin C may improve the reproduction of B- and T-cellswhich are important white blood cells for the immune system.
The amount of vitamin C needed for increasing white blood cells may depend on the condition and overall health needs. More research in humans is needed to better understand the link between vitamin C and white blood cells.
To raise your white blood cell countyou may want to avoid alcohol and tobacco use, take Omega-3s and zinc, and eat a balanced diet. For example, a study found that the Mediterranean diet had an effect on the white blood cell counts of adults at risk for cardiovascular disease.
Depending on the cause of low white blood cells, you may also need to take medications like myeloid growth factors. Antiviral foods may include fermented vegetables kimchifermented milk yogurt and kefirherbs oregano, fennel, peppermint, and aloe veragarlic, ginger, turmeric, black cumin, cinnamon, licorice root, mushrooms, and citrus fruits.
Some foods may boost your immune system while others will help with their antimicrobial properties. This means they may help fight bacteria, viruses, and other pathogens that cause infections.

: Immunity-boosting foods| Nutrition and Immunity | Our immune systems are influenced by a number of different factors, not just one specific nutrient. Getting enough sleep and exercising regularly — as well as eating a balanced diet — are all key for supporting the body to fight infection and disease. One of the main components of our immune system is the millions of defensive white blood cells that patrol the blood stream and lymphatic system, constantly on the lookout for suspicious signs of disease. Once detected, our immune system mounts a response to fight an infection and remembers it for the next time. What we eat can support the immune system by providing the body with the nutrients required to build a protective response and counteract oxidative stress including antioxidants, phytonutrients, vitamins, minerals and fibre. Try to include a wide range of colourful whole foods, fruits and vegetables from the list below; the more variety the better. They contain five times the antioxidant activity of a regular orange with the same amount of vitamin C. Research has shown that a daily glass of blood orange juice for seven days could help reduce inflammation and raise antioxidant levels in the blood. Greek yogurt contains probiotics and is packed with more protein than regular yogurt. A published meta-analysis discovered that people who ate probiotics daily had a lower risk of catching a cold than those who did not eat any probiotic-rich food. Pomegranate contains polyphenols that can help treat and prevent coughs and colds. Studies have shown that concentrated amounts of polyphenol antioxidants, like those found in pomegranate juice, can reduce the duration of a cold by as much as 40 per cent. Brazil nuts contain selenium, an important mineral to protect against oxidative stress. Selenium has also been shown to help the body fight viral infections so including a couple of Brazil nuts each day as part of a meal or snack can ensure the immune system has enough selenium to stay strong. Wild salmon is filled with zinc, a nutrient that has been proven to assist with reducing common cold symptoms. It is also high in omega-3 fatty acids which assist in reducing inflammation, prevent viral infections and enhance the functioning of immune cells. Broccoli and other cruciferous vegetables were proven to help boost immunity, because of the sulforaphane , a plant chemical in the vegetable, which switches on antioxidant genes and enzymes in specific immune cells. In doing so, they combat free radicals to reduce the risk of disease. Green tea is frequently included on lists of super healthy foods for good reason. It contains flavonoids, an antioxidant that boosts immunity, and has anti-inflammatory properties. When it comes to treating a common cold, ginger is one of the best foods for relief. Shallots contain as much as six times more polyphenols than some everyday onions. This is down to the quercetin content. Quercetin plays an important role in helping the body combat free radical damage which is linked to disease. Dark chocolate contains magnesium which is a vital mineral for supporting the immune system. Magnesium helps lymphocytes bind to pathogens so they can be removed from the body. Make sure to choose the very dark chocolate 80 per cent cocoa and over , to get the most magnesium and immune-boosting benefits. With twice the vitamin C content of an orange and loaded with antioxidants like lutein and zeaxanthin, kiwis are bite for bite one of the most nutritionally dense fruits in the world! Various compounds from vitamin C and fibre, to carotenes and polyphenols, have been shown to be beneficial to immune function and all of these also just so happen to be found in a kiwi. Many herbs and spices are known for their antimicrobial and immune boosting properties. Oregano is one such herb that is worth including in your cooking. It contains essential oils which are known for their antimicrobial, antiviral and antifungal properties and could be helpful in treating bacterial infections. What we eat can influence our immune system, with certain foods associated with lowering the risk of disease or reducing recovery time if we do get ill. As always, the bottom line is to choose fresh, whole foods as much as possible, and to eat a wide variety of colourful and tasty foods. By including fewer ultra-processed foods, you can reduce disease risk and promote healthy immune function. Further reading: The 20 healthiest foods. How to boost your child's immune system.

Another meta-analysis found that garlic consumption may lower the risk of colorectal cancer. Selenium—plentiful in shellfish such as oysters, lobsters, crabs, and clams—helps white blood cells produce cytokines, proteins that help clear flu viruses out of the body. The amino acid cysteine released from chicken during cooking chemically resembles the bronchitis drug acetylcysteine , which may explain the results. Lofton adds that one peer-reviewed study investigated how curcumin may be useful in preventing and treating chronic diseases associated with inflammation, and found that it has potential as a therapeutic agent for conditions such as arthritis, cancer, and cardiovascular disease, in part due to its immune-modulating properties. Black tea contains L-theanine , an immune-boosting amino acid. Both black and green tea also contain catechins, antioxidants that have been found to possibly prevent the flu. Zinc is essential for the development of white blood cells, the intrepid immune system cells that recognize and destroy invading bacteria, viruses, and assorted other bad guys, says William Boisvert, Ph. Beef is a good source of zinc , as are milk and beans. She recommends adding pork as another zinc source in a balanced diet, be it a grilled pork chop or tenderloin. Almonds are high in vitamin E, containing around 7 mg per serving, explains Lofton. Vitamin E is an antioxidant that can help protect cells from damage and therefore, potentially prevent illness. You may not think of skin as part of your immune system. But this crucial organ serves as a first-line fortress against bacteria, viruses, and other undesirables. To stay strong and healthy, your skin needs vitamin A. One of the best ways to get vitamin A into your diet is from foods containing beta-carotene which gives them a vibrant orange pigment , like sweet potatoes, carrots, squash, canned pumpkin, and cantaloupe. Along with orange produce, dark, leafy greens like kale contain vitamin A and can help bolster immune function. On top of that, studies show that not getting enough vitamin C can actually impair your immune response and make you more susceptible to infections. While the jury is still out on whether or not vitamin C can truly prevent a cold, a review of research suggests supplementing with C can help stave off respiratory infections—or at the very least, help reduce the severity and length of your symptoms if you fall ill. Lofton says broccoli is rich in vitamins A and C, as well as fiber, which work together to support a healthy gut microbiome and immune system. While the sunshine vitamin is hard to come by naturally through your diet, foods high in vitamin D , such as eggs, can help you meet your daily intake. The National Institutes of Health NIH recommends a minimum of international units IUs of vitamin D for most adults daily, but other accredited organizations suggest aiming much higher. Not a fan of eggs? People around the world have turned to mushrooms for a healthy immune system for centuries, and co ntemporary researchers now know why. Like yogurt, kefir, a fermented yogurt drink, contains gut- and immune-boosting probiotics. Salmon, mackerel, and herring are rich in omega-3 fatty acids, which reduce inflammation , increasing airflow and protecting lungs from colds and respiratory infections salmon is another vitamin D source, too. One animal study also found that the nutrient may help ward off various strains of the flu. As we all probably know, citrus fruits like oranges and grapefruit are high in vitamin C, a nutrient that is, like the orange juice commercials say, essential for immune function. More than just a salty summer snack meant for baseball games, Lofton points out that sunflower seeds are high in vitamin E, an antioxidant that can help protect cells from damage. Blackberries are high in antioxidants, plant compounds that can help shield the body from environmental stressors and germs, says Lofton. They also contain fiber and vitamin C, which support a healthy immune system and gut. If you eat a plant-based diet and are looking to up your protein intake for immunity function, Weiler recommends having a legume salad or a side of baked beans. According to the United States Department of Agriculture USDA , a cup of cooked lentils boasts 18 g of protein. The satisfyingly crunchy snack also has a high water content, which can boost hydration for immune and digestive systems in need. |

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. It is also essential to be mindful of the other lifestyle factors that may affect immune system health, such as exercising and not smoking. Anyone who gets frequent colds or other illnesses and is concerned about their immune system should speak to a doctor.
