Top 10 Foods To Boost Your Immune System
Getting vitamin C from food makes sense. Oranges and lemons naturally come to mind when you think of foods high in vitamin C, but know that you can get the vitamin C your immune system needs by eating kale, spinach, bell peppers, papaya and strawberries.
Eating vitamin C-rich foods along with certain iron-rich beans and vegetables, such as lentils and kale, helps the body absorb iron more efficiently. This is important for vegetarians and others who eat little or no meat.
Bananas aren’t just a prebiotic food — they support gut health — they’re rich in vitamin B6. This vitamin is necessary for the proper functioning of the immune system. Bananas are a great base for your next smoothie! Other foods high in vitamin B6 include cold-water fish, lean chicken breast, chickpeas, and potatoes. Do not mix prebiotics with probiotics. Prebiotics serve as food for probiotics. Good sources of prebiotics include: garlic, leeks and onions.
Immune Boosting Foods
Almonds, hazelnuts, peanuts and sunflower seeds provide the body with the necessary vitamin E, an important antioxidant. If you need a healthy snack, consider raw or roasted almonds as an option. Additionally, cashews are rich in zinc, which boosts your immune system by activating T cells.
Carrots and other carotenoid-rich fruits and vegetables help support immune system function. Carotenoids are converted into vitamin A in the body and provide an antioxidant effect. Other foods containing carotenoids include sweet potatoes, pumpkin, squash, and cantaloupe. Stock the fridge and treat yourself to immune boosting soups and more!
Fish such as salmon, tuna, and sardines are natural sources of vitamin D. Although vitamin D is produced by the body, it may need to be supplemented. A surprisingly high number of people are deficient in vitamin D. Many fortified foods on the market, such as orange juice, milk, and cereal, can help you get the right amount of vitamin D.

Staying healthy and avoiding infections has never been more important. Social distancing can keep other people’s germs from getting to you, and washing your hands frequently will kill them if they get to you. But what can you do to improve your body’s ability to fight germs if, despite your best efforts, you catch them?
What you eat can make a big difference in how well your immune system works. “It’s very important for older people to have a nutrient-dense diet,” says Dr. sc. Katherine L. Tucker, director of the Center for Population Health at the University of Massachusetts Lowell. Immune responses decline with age, and many older people suffer from chronic low-level inflammation and underlying health conditions, such as heart disease and diabetes, which can also interfere with the body’s defenses . And they can become less efficient at absorbing many infection-fighting vitamins and minerals.
Best Foods For Your Immune System
Getting your immune system into fighting shape won’t happen overnight. “I don’t think you can suddenly change your diet today and tomorrow your immune system will be happier,” says Philip C. Calder, Ph.D., professor of nutritional immunology at the University of Southampton in the UK. United. But increasing your diet now can pay off in the long run with fewer sick days and better overall health.
The immune system is often compared to the police. Made up of a complex network of molecules, cells, tissues and organs, it patrols throughout the body. Part of the force, the innate immune system, is on the front line – in the skin, saliva, digestive system and respiratory tract, and elsewhere – and acts quickly to fend off foreign invaders. The other part, the adaptive (or acquired) immune system, works for days to track down bad actors who have breached the first line of defense and helps develop antibodies against them.
Because the components of the immune system are so diverse, keeping it healthy means getting a range of vitamins and minerals, which often work together in dozens of immune-boosting roles. Vitamin A, for example, is important for healthy skin cells and the digestive tract. Vitamins C and E are antioxidants that protect cells and tissues from the flood of harmful free radicals that occur when the immune system fights off invaders. The creation of new immune cells and the initiation of the immune response require vitamins of the B group (B6, B12 and folate). Other nutrients that boost your immune system include copper, iron, magnesium, omega-3 fatty acids, protein, selenium, vitamin D, and zinc.
Can Certain Foods Help “boost Your Immunity”?
The best diet to defend your body is one based on whole, minimally processed foods that are mostly cooked at home. Eating too many foods high in saturated fat, sugar and salt can weaken immunity. Along with many nutrients and phytochemicals, plant foods also contain fiber that feeds healthy bacteria in your gut. These bacteria also help the immune system, says Calder.
Fruits and vegetables provide most of the body’s need for vitamins A and C, which are important bacteria fighters. Foods are also typically rich in antioxidants that reduce inflammation and protect immune (and other) cell membranes from harmful oxidation. Aim for at least 2½ cups of vegetables and 2 cups of fruit per day. Mix the type and color of your produce for a wide variety of nutrients. Tucker recommends at least one green vegetable every day, such as spinach, kale, Swiss chard, broccoli, arugula, or cabbage. Bell peppers, potatoes, sweet potatoes and carrots are also high in vitamin A and/or C. Citrus fruits are high in C, as are tomatoes, strawberries and kiwi fruit.
Nuts and seeds are excellent sources of essential vitamins and minerals, fiber, protein and healthy fats. Vitamin E is a powerful antioxidant, and most people do not meet the daily requirement (15 mg). Tucker says chewing on a handful of sunflower seeds or almonds each day will help.
Fruits That Boost Your Immune System
Almonds also provide copper and magnesium, which studies have shown are involved in DNA repair and antibody production. Sunflower seeds contain selenium, copper, folate and zinc. (Zinc deficiency is responsible for 16% of lower respiratory tract infections worldwide.) Hazelnuts, pistachios and walnuts are full of B6.
Beans and whole grains provide nutrients and contain fiber that helps restore healthy gut bacteria. Lentils are a good source of copper, folate and iron; chickpeas and black beans provide zinc; and cranberry beans are high in folate. Whole grain breads and cereals and the whole grains themselves (barley, bulgur, wheat berries, oats, and quinoa, among others) provide you with B vitamins, copper, iron, magnesium, and zinc.
Healthy oils, such as olive, flaxseed, and canola, provide omega-3 fatty acids that help control inflammation and regulate immune cell activity. A tablespoon or two of oil-based salad dressings can also help your body absorb the antioxidant carotenoids (which the body converts to vitamin A) and other nutrients found in green and other vegetables.
Nutrients For A Strong Immune System
“You need animal food to provide things that plants can’t provide adequately,” Calder says. “A good example is vitamin B12, where meat is a very good source.” Some vitamins and minerals are more available in foods of animal origin than in foods of plant origin. Zinc, for example, is more easily absorbed from seafood and meat than from beans and whole grains. The corresponding proteins also have building blocks for immune cells.
Meat and fish. Although you don’t need either on your plate at every meal (a few times a week is fine), they provide essential nutrients. Lean meat and poultry contain enough B vitamins (especially vitamin B12, which is deficient in about 20% of older people), iron, selenium and zinc. Clams are a good source of zinc, copper and selenium. And fatty fish like salmon, tuna and mackerel are important sources of omega-3 fatty acids, as well as B vitamins, selenium and vitamin D, which may protect against upper respiratory tract infections and heart disease. overreactions of the immune system.
Dairy products increase your stores of vitamin A, certain B vitamins, zinc, magnesium and selenium. Fortified dairy products, such as milk and yogurt, can provide hard-to-find vitamin D. Yogurt (plain is best to avoid added sugars) is also full of probiotic bacteria that help maintain a healthy gut microbiome. In two studies in healthy older people, one lasted longer than 8 weeks and the other lasted longer than 12
