14 Immunity Boosting Superfoods to Remove ToxinsImmune-boosting superfoods -
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.
Kiwi contains vitamin E and water, which translates to protection and hydration essential to all bodily systems. Blueberries are abundant in polyphenols, an antioxidant that protects against inflammation.
Brazil nuts are high in selenium, explains Weiler. Selenium, via selenoproteins and enzymes, has antioxidant properties that help to break down peroxides that can damage tissues and DNA, per Harvard T. Chan School of Public Health. On its own, sulforaphane has been shown to increase the levels of several antioxidant compounds by inducing a compound in our cells called NRF This is sometimes called the "master regulator" of antioxidants, which means it helps increase the production of other antioxidants.
NRF-2 can play a role in lowering inflammation seen in many diseases like cancer, chronic obstructive pulmonary disease and liver disease. Most cruciferous vegetables, such as cauliflower and broccoli, contain large amounts of glucoraphanin, which converts to sulforaphane during digestion.
However, young broccoli sprouts contain between 10 and times more sulforaphane than mature broccoli! The best way to eat broccoli sprouts is raw — for instance, in salads — because sulforaphane is easily broken down by cooking. I always aim to eat two ounces of broccoli sprouts a week.
Not only does garlic make everything taste more delicious, but this pungent vegetable has multiple compounds that regulate the immune system.
Studies on garlic find that it is immune-stimulating — increasing the activity of NK cells, a type of immune cell that has granules with enzymes that can kill tumor cells or cells infected with a virus.
At the same time, garlic is anti-inflammatory and can be cardioprotective by lowering cholesterol and blood pressure. You can incorporate garlic into almost any recipe — so use it whenever you can — and you can also find it in supplement form if you're not a fan of the taste.
If I had to pick one culinary compound out of nature's apothecary for it's immune-supportive effects, I'd go with turmeric root. The bright yellow-orange root contains a magical compound called curcumin, which has many key benefits:.
Turmeric is a great spice to use in cooking, although it does impart a bright yellow hue to your skin tongue and teeth.
And, because it's not well-absorbed in the GI tract, you'd need to eat gobs of it to achieve immune-modulation effects.
Given that, curcumin supplements are the best way to get this beneficial compound. Dosages vary based on need. For general health, I recommend about 1, milligram a day in divided dosages. Heather Moday is a board-certified allergist, immunologist and functional medicine physician.

Eating a variety of vegetables may help you boost your immune system. Red peppers, spinach, and broccoli are good choices, as well as ginger, turmeric, and garlic.
Eating all types of fresh fruits regularly may help your immune system function well. Bananas, in particular, contain a substance called lectin. One study in rodents found that banana lectin may enhance the immune system.
Fresh foods can provide our bodies with the nutrients our immune system needs to work correctly. You need a variety of fruits, vegetables, whole grains, herbs, and spices in your diet to enable your body to stay as healthy as possible.
Good choices of foods to boost the immune system include citrus fruits, spinach, almonds, papaya, and green tea. Although eating a balanced diet is key to boosting your immunity, foods alone cannot and should not replace medical treatment, unless your healthcare professional recommends it.
