10 Powerful, Yet Little-Known Immune Boosting Ingredients

It’s that time of year when getting sick becomes much more daunting. It interferes with all the family gatherings. Not to mention, the likelihood of getting sick from said family gatherings is relatively high.

You don’t want to be that person to bring the common cold home with you or fall victim to an illness days after returning home from your trip. That’s why preparing the body for the holidays well in advance is crucial.

We will talk about 10 little-known immune-boosting ingredients to add to your diet as soon as possible. These ingredients should support your immune function to reduce the chances of catching something during the holidays. Whether you are going home for an annual visit or using vacation time for that trip you’ve been planning for years–your body will be ready for anything!

Immune System Functions

In the simplest terms, the immune system is responsible for keeping outside invaders from getting inside the body. That includes germs like bacteria, viruses, fungi, and other harmful toxins.

The immune system consists of two main parts. You are born with an innate immune system or the rapid response system. The adaptive immune system develops from the exposure of microbes or chemicals released by microbes.

Both immune system parts work harmoniously to create a more cohesive and responsive immune system against outside threats.

What Happens When Your Immune System Weakens?

A variety of factors trigger a weakened immune system. This may be due to poor diet, exercise, insufficient sleep, significant weight gain, or too much stress.

Here are some common symptoms of a weakened immune system:

  • Frequent infections. Infections like pneumonia, meningitis, bronchitis, and skin infections are common among those with weakened immune systems.
  • Recurrent infections. You may also experience repeated infections. For example, The American Academy of Allergy Asthma & Immunology reports that one sign of immune deficiency has four or more ear infections in a year.1
  • Inflammation and infection of internal organs. Internal inflammation occurs when your immune system sends out cells to fight bacteria or heal an injury.
  • Certain blood disorders. Blood disorders, like low platelet count or anemia, may be a sign of primary immunodeficiency.

If you have any of the above symptoms, you must consult with your doctor. Sometimes a weakened immune system may indicate a more severe immune deficiency that requires physical expertise.

However, a weakened immune system is often caused by unhealthy life choices and can easily be corrected with some simple diet and lifestyle changes.

Natural Ways to Nourish Your Immune System

In a way, the immune system is a direct consequence of how we treat our bodies. For example, alcohol and cigarettes may impair the immune system. For most people, there will be times in their life when they have a fragile immune system and other times in their life when it is strong and active.

There are several small changes you can make if you worry about the current strength of your immune system.


Frequent and regular exercise can dramatically improve the state of your immune system. During and after exercise, your body releases more pro- and anti-inflammatory cytokines (small proteins), increases lymphocyte circulation, and improves cell recruitment.2

In addition, physical activity can flush bacteria and germs out of the airways in the lungs. Therefore, reducing the chance of a negative impact from those germs and bacteria.3

While most people wait until the New Year to get into the gym, it may be beneficial for the holidays to begin a couple of months earlier.

Reduce Stress

Stress can reduce the number of natural killer cells that fight off bacteria and viruses, making your body more prone to illness and other infections.4

It might be difficult to eliminate stress altogether, especially this time of year, but do your best to avoid unnecessary stress responses.

Get Enough Sleep

Sleep and the circadian rhythm are strongly linked to immune function and success. One study on the sleep cycle revealed strong communication between the central nervous system and the immune system during sleep.5

A lack of sleep means your body has no time to repair and rest to prepare for the day. This makes you more likely to come down with an unwanted common cold.

Watch Your Diet

Have you ever heard the expression, you are what you eat? Well, it proves especially true when it comes to your immune system.

Your diet might also be the easiest thing to manipulate in your life leading up to the holidays. The vitamins and minerals you consume can feed and nourish the immune system for a much more effective attack on unwanted germs.

We will talk about some of the less common ingredients you can add to your diet that will improve immune performance before holiday celebrations.

10 Obscure Immune Boosting Ingredients

Most of us have heard about oranges boosting the immune system with a shot of Vitamin C to the system. Maybe you’ve always relied on chicken noodle soup or chicken broth (which affects the white blood cells associated with inflammation) to replenish the body while sick. Or you’ve possibly turned to garlic or ginger tea for support during an illness.

Those are some of the more common remedies that support immune function, but you may be overlooking some other key ingredients that can help in the battle.

1.   Turmeric

Turmeric (Curcuma longa) is a flowering plant of the ginger family. It is a common spice found in many different foods. It is a key ingredient in curry powder, giving the curry a bright yellow hue.

Proponents That Support Immune Function

Turmeric has been used for centuries in natural remedies and has been hailed for its anti-inflammatory effects. Turmeric is packed with over 300 nutrients to help build the body’s function and improve immune response.

How to Incorporate It Into Your Diet

There are several ways to add more turmeric to your diet. If you aren’t a fan of curry, you can simply boil raw turmeric and drink it as a tea beverage in the mornings.

You can also mix one teaspoon of turmeric with one cup of sweet apple cider and one teaspoon of grated ginger for a more flavorful cider beverage.

2.   Honey

Honey may not be a surprise for many. Honey is a go-to for colds and sore throats, but it has so many nutrients and vitamins that are proven vital for the immune system.

Proponents That Support Immune Function

Honey is composed of amino acids, vitamins, minerals, iron, and zinc that help support the body. For immune response, honey induces leukocytes to release cytokines, which improves and revamps tissue repair within the body.

How to Incorporate It Into Your Diet

The best thing about honey is how easy it is to add to your daily diet. You can use it as a healthy alternative to sugar in your coffee or tea. You can add it to your yogurt, smoothies, oatmeal, and cereal! As a tasteful immune-boosting proponent, there are endless ways to incorporate honey into your diet.

3.   Blueberries & Other Fruits

You may know how beneficial citrus fruits are for the immune system, like oranges, but did you know blueberries have just as much benefit?

Proponents That Support Immune Function

Blueberries are often referred to as an “immune-boosting superfood,” and for a good reason. Blueberries contain flavonoids, an antioxidant that can reduce cell damage and boost your immune system. In addition, blueberries are loaded with beneficial vitamins like vitamin C, vitamin A, and potassium.

How to Incorporate It Into Your Diet

Blueberries can be pretty easy to find. All you have to do is load up on the little berries and add them to your meals as much as you’d like. You can put more blueberries in smoothies, oatmeal, on pancakes, or mix with some citrus fruits in a bowl of natural yogurt. You can also just have a handful of blueberries for a simple afternoon snack!

4.   Fermented Foods

Fermentation is the conversion of carbohydrates to alcohol or organic acids using microorganisms. Some popular fermented foods include kimchi, sauerkraut, miso, cider, wine, and cultured yogurt.

Proponents That Support Immune Function

Fermented foods are especially helpful in restoring gut health. Immune-related symptoms are often found in the gut, triggered by an unbalanced immune system that results in too much inflammation.

Fermented foods are high in probiotics, improving your immune function and reducing the risk of infection. These types of foods are especially effective in improving gut health.

How to Incorporate It Into Your Diet

Fermented foods can often be a hit or miss for many people. You either love them or hate them. Kombucha is a fermented drink that has been gaining popularity for its immune-focused properties. You can keep a bottle of fresh kombucha in your fridge to sip on. You can also add more fresh kimchi or sauerkraut to your prepared meals.

5.   Sweet Potatoes

Sweet potatoes are the sweeter companion to potatoes. Most people know sweet potatoes but may not be aware of their massive benefits to the immune system.

Proponents That Support Immune Function

Sweet potatoes are rich in beta-carotene, which is converted to vitamin A in the body. Vitamin A is wildly beneficial to the immune system, as well as lowering blood levels. Sweet potatoes are also high in antioxidants and anti-inflammatory agents that can support healthy immune function.

How to Incorporate It Into Your Diet

Sweet potatoes are the perfect supplement for regular potatoes in any meal. They are sweeter, tasty, and can be cooked in a variety of ways. From grilled sweet potatoes served on the side with eggs for breakfast, to baked sweet potato, to even sweet potato gnocchi! Your options are unlimited with this popular form of potato.

6.   Mushrooms

In general, vegetables are great for the body. Almost all vegetables, especially leafy greens, can contribute to a healthy immune system. But mushrooms, in particular, are proven to be especially useful for your overall health.

Proponents That Support Immune Function

Mushrooms are loaded with B vitamins and riboflavin that help support the immune system. One important proponent of mushrooms, however, is selenium. Selenium can help increase white blood cell production to better fight infections. Our bodies don’t make selenium naturally, so we must turn to outside sources, like mushrooms.

Many studies show mushrooms can stimulate anti-inflammatory cytokines to improve immune response.

How to Incorporate It Into Your Diet

Unless you are a considerable adversary against mushrooms, they can be relatively easy to add to your diet. You can cut up mushrooms to mix with your eggs, rice, salads, or pasta. They go well with just about any prepared meal.

7.   Bell Peppers

We already mentioned how vegetables are a valuable source of fuel for the immune system. But bell peppers (specifically orange and red bell peppers) often get overlooked when they should not be. Bell peppers are an important inclusion on the list of 10 immune-boosting ingredients.

Proponents That Support Immune Function

Bell peppers contain a significant amount of vitamin C. Vitamin C is a powerful antioxidant that prevents infections by helping your body build valuable antibodies against said infections.

Orange bell peppers contain 158 milligrams of vitamin C, while red bell peppers contain 142 milligrams. For comparison, an orange has about 50 milligrams of vitamin C.

How to Incorporate It Into Your Diet

There are endless opportunities for including bell peppers. You can incorporate various bell peppers into your diet in the same way as mushrooms. Be conscious of adding more bell peppers into your typical meals, whether in salads, pasta, omelets, or homemade stir-fries.

8.   Sunflower Seeds

Sunflower seeds are loaded with different vitamins and minerals that can improve your overall health and your immune function. Some studies link sunflower seeds to improved cardiovascular health and reduced risk of high blood pressure and high cholesterol.

Proponents That Support Immune Function

Sunflower seeds are high in zinc and selenium, two essential vitamins to the immune system. The body needs zinc to maintain and develop immune cells. It has been proven that selenium boosts immunity, reduces inflammation, and fights infection.

How to Incorporate It Into Your Diet

Sunflower seeds can be used as a seasoning in many different ways. You can sprinkle sunflower seeds on your salads, add to your homemade trail mix, mix in with your stir fry, or replace your peanut butter with sunflower butter.

9.   Aloe Vera

Aloe vera is a succulent plant species that grows in tropical, semi-tropical, and arid environments. It has been used in herbal medicine for centuries, often known for helping with burns, and used as a topical pain treatment.

Proponents That Support Immune Function

Aloe vera helps the immune system on a variety of different fronts. It is shown to increase white blood cell counts, promote gut health, increase antioxidant support, and give the body essential amino acids to fight infections.

How to Incorporate It Into Your Diet

You can get a fresh gel directly from an aloe vera plant. From this aloe vera gel, you can add juice to a tea, smoothie, or any drink of choice. You can also even drink small amounts of the aloe vera gel directly. If you are drinking pure aloe vera gel, start with a small amount (one tablespoon) to see how your stomach reacts.

10.   A Variety of Natural Herbs

There are too many natural herbs with significant immunity-enhancing qualities to them. You may have heard of some of these herbs, while others will be relatively foreign to you.

List Of Some Immune Boosting Herbs

Here is a list of a few of the most beneficial immune-boosting herbs you can find:

  • Astragalus root has many anti-inflammatory and antibacterial properties.
  • Angelica root has been used in ancient Chinese medicine to positively influence the immune system.
  • Echinacea can reduce pain and inflammation.

Even adding some of these herbs could go a long way with your immune function.

How to Incorporate It Into Your Diet

One of the best things about herbs is how easy it is to add to your diet. You can go the easy way and make a tea mixed with one or several of the herbs above. You can also sprinkle small amounts onto your prepared meals for an extra immune boost.
