6 Must-Try Immune-Supporting Foods (+ 3 Recipes)

Strengthen immunity and build your defenses!

By: Lexy Parsons

Building a strong immune system is important no matter what time of year, but it’s been something that’s been on all of our minds more than ever lately. The good news is that supporting our immune system looks a lot like taking really good care of ourselves — think handwashing, getting enough sleep, reducing stress, and moving our bodies regularly. But in addition to the foundations of a solid self-care routine, clean eating goes a long way. Ahead, we’re sharing some research-backed immune-supporting ingredients that happen to be Registered Dietitian-approved and offer a wide range of health benefits, beyond just immune support!

6 Delicious Immune-Supporting Ingredients

#1 Garlic

It should come as no surprise — garlic is a top contender on our immune-supporting ingredients list. Garlic is known as one of the oldest medicines in the world, says Lori Zanini, RD, CDE, co-founder and creator of For The Love of Diabetes, a fast-growing online diabetes nutrition & management program, author of Eat What You Love Diabetes Cookbook and The Diabetes Cookbook & Meal Plan for the Newly Diagnosed

Allicin, the bioactive compound found in garlic, is responsible for garlic’s potent anti-inflammatory and antimicrobial properties, says Zanini. Research shows the immune-boosting benefits of garlic are activated when garlic is eaten in its raw form! Chop it, chew it, but don’t cook it — if you’re strictly eating it or its immune-supporting properties, that is! Evidence from a recent study supports garlic as one of the best immune-supporting ingredients, suggesting garlic supplementation may enhance immune cell function! 

#2 Ginger 

Ginger shots, ginger smoothies, ginger tea — ginger is one of those foods that makes its way into every immune-boosting recipe! So, what makes this spice one of the best immune-supporting ingredients? 

The antioxidant and anti-inflammatory properties in ginger make it a great immune system booster, says Zanini. Research suggests the active compound in ginger, gingerol, may help improve the immune system response, reduce oxidative stress, increase antibodies, and act as an antibacterial agent in the body. 

#3 Elderberry

If you’re looking for natural ways to bolster your immune defense, then chances are, you’ve heard about elderberry! Studies suggest the rich antioxidants found in elderberries, known as anthocyanins, could help stimulate the immune response. Zanini agrees, the phytonutrients and antioxidants in elderberries are essential immune-supporting ingredients.

#4 Turmeric 

When it comes to immune-supporting ingredients, look no further than the anti-inflammatory superstar, turmeric! Research shows the anti-inflammatory properties in turmeric increase the immunomodulating capacity of the body, helping the immune system defend against illness and disease. 

The potent anti-inflammatory properties come from a substance called curcumin, the active compound in turmeric, says Zanini. Be sure to pair turmeric with black pepper in order to optimize absorption! Research suggests black pepper enhances turmeric’s bioavailability by up to 2000%!

#5 Citrus 

Did you know citrus is a winter fruit? Citrus fruits ripen to their sweetest and juiciest during winter months, which just so happen to be one of the germiest times of the year. Mother nature may have been strategic in this — after all, citrus is one of the best immune-supporting ingredients! 

Studies show citrus fruits are a good source of Vitamin C, an important vitamin for building both immunity and immune response. Research suggests Vitamin C may protect against pathogens and reduce oxidative stress. This is not a nutrient you want to be deficient in! Studies show Vitamin C deficiency can increase susceptibility to illness and infection. So consider adding some nutritious vitamin C-rich foods to your diet like oranges or other nutritious options like broccoli, bell peppers, and strawberries. 

#6 Fortified Greek Yogurt 

While greek yogurt is typically a topic of conversation when it comes to gut health, it’s also one of the best (Registered Dietician-approved) foods to boost immunity. Greek yogurt contains immune-supporting ingredients like probiotics, Vitamin D, and protein, says Zanini. To keep our immunity up, we want to keep the microbiota (the good bacteria in our gut) flourishing and happy — after all, research suggests 70% of the entire immune system resides in our gut! An easy (and delicious) way to do this? Incorporating probiotic-rich foods, such as greek yogurt.  

Opt for a greek yogurt that is fortified with Vitamin D to supply your body with additional immune-supporting ingredients, says Zanini. Research shows Vitamin D is essential to maintaining a strong immune system, helping to stimulate immune functions. In fact, studies suggest Vitamin D deficiency is associated with increased susceptibility to infection.  In addition to consuming Vitamin D rich food sources like greek yogurt, be sure to get at least 15 minutes of sun exposure, says Zanini.
