TheDailyMeal.com: Eat the Flu Away with These Immune-Boosting Foods

Pumpkin

Health specialist Lori Shemek (who also knows a thing or two about dieting) has shared some foods beyond the orange that will help keep your immune system at its strongest and the flu away.

Just like with carrots, pumpkins get their orange color from beta-carotene, which is a great source of vitamin A, says Shemek. A good supply of vitamin A helps with cellular communication within your immune system, making sure it’s alert and ready for when the flu virus strikes.

Citrus Fruits

While most of us already know that oranges are a great way to fight off colds and the flu, Shemek tells us that other citrus fruits should not be overlooked as well. The more vitamin C the better, she says, because it helps with the body’s production of white blood cells to help prevent infection.

Tomatoes

Tomatoes contain an antioxidant called lycopene, which aids the body’s natural defenses against harmful free radicals, says Shemek. And, even better for us, cooking tomatoes is the best way to get the most lycopene out of them.

This Slow-Roasted Tomatoes recipe is perfect to make and have on hand whenever you're looking for a dose of lycopene.

Dark Turkey Meat

Along with other types of protein, dark turkey meat is the best type you can consume because it contains more health-boosting vitamins and minerals than any other cut. As turkey is a good source of zinc and selenium, which boost your body’s defense system and increase production of white blood cells, eating the dark meat will ensure you get the most of these virus-fighting vitamins.

Wild Salmon

Like all cold-water fish, wild salmon is a great source of omega-3 fats, says Shemek. These are highly effective with the immune system because they increase the activity of macrophages — white blood cells that annihilate bacteria in your body.

Kefir

Kefir, or fermented milk, helps create healthy gut microbes in your body, which make up a large part of your body’s defense system. "In fact, your digestive system is 80 percent of your immune system," says Shemek, so the consumption of kefir not only improves immune-cell function but builds a fortress in your intestinal tract against bugs.
