Don’t let the coming cold season get you in its clutches. Avoid falling sick by eating these 15 foods that boost the immune system.

Immune Boosting FoodsThe immune system protects us from illness and disease. This sounds simple, but there are countless types of pathogens and ways they attack the body. We have bacteria, viruses, parasites, mutated cells, and even misfolded proteins waging war against our health. This war is constant and intense. Thousands of different species of bacteria live on our skin alone, and even more live inside of us, some good and some not so good. These pathogens constantly evolve and adapt to better survive their environments, resist drugs, avoid detection, and find new ways into the body. Fortunately, our immune system is also adaptive and multifaceted, incorporating the skin, respiratory system, digestive system, lymphatic system, many organs, mucus membranes, and a throng of specialized cells in the battle to keep us healthy.

You can do many things to keep your immune system at peak performance. Drink plenty of clean, purified water. Hydration is important to every system in the body, and the immune system relies heavily on consistency of circulatory fluid both in lymphatic vessels and blood vessels. Nutrition and exercise play a role in resisting disease for the same reason. Eating well supplies the body with the vitamins and minerals it needs to work, and exercise improves the circulation of disease fighting cells and nutrients.

What we’re exposed to as children is also important. Breast feeding is crucial to supplying infants with antibodies that help them resist infection while their bodies learn what is safe and what isn’t. Some exposure to pathogens early on can be a good thing. It’s how our bodies figure things out, especially for young children. This doesn’t mean you should forgo all hygiene or put yourself at unnecessary risk, but a little dirt and germs are part of building a strong immune system that doesn’t overreact when faced with something new. Children who grow up on a farm or have pets are less likely to develop allergies.

There are also plenty of foods that help boost the immune system. They help prevent disease or ease you through a cold faster. Fresh and raw foods are a great place to start. They supply a ton of vitamins, minerals, and antioxidants to keep illness at bay, but here are a few of the superstars.

Probiotics

Fermented foods help the friendly bacteria in the body thrive. They, in turn, take out the less friendly varieties and help us break down foods that can be hard to digest. Sauerkraut, kimchi, kombucha, and Ormus Supergreens are a good place to start.

Oats and Barley

These grains contain beta-glucans, a fiber that has antimicrobial, anticarcinogenic, and antioxidant properties. They stimulate the immune system, making it more efficient.

Garlic

Garlic contains allicin, which fights bacterial infections and cancer. Garlic also has beneficial effects on the circulatory system, and any boost to your circulatory system improves immunity and many other aspects of health.

Nuts and Seeds

Brazil nuts and sunflower seeds are a rich source of selenium, which helps white blood cells produce the proteins they need to clear out viruses. Pumpkin seeds provide zinc, which is important in the development of white blood cells.

Dark Chocolate

Dark chocolate is another good source of zinc to boost the immune system. It also releases endorphins that reduce stress. Stress can have a negative effect on the immune system.

Coconut oil contains medium chain triglycerides that combat viruses, fungi, bacteria, and some parasites, especially once they’ve been digested. They also boost energy levels and reduce inflammation.

Turmeric

Curcumin, the powerful, pungent, and colorful compound in turmeric, helps the body destroy many types of cancer cells. It may also kill harmful bacteria in the intestines.

Sweet Potatoes

These healthier versions of potatoes are rich in beta carotene, a component of healthy skin when transformed into vitamin A. The skin is the first line of defense against infection. Vitamin A is also important to T-Cells and natural killer cells.

Mushrooms

Mushrooms also contain beta-glucans, the immune boosting fiber, and selenium to increase production and activity of white blood cells. We’re just beginning to understand the many other compounds in mushrooms that bolster health.

Cabbage

Cabbage contains sulfur compounds that are antimicrobial. It also contains glutamine, an amino acid used by immune cells during times of stress, inflammation, and infection, especially by lymphocytes, macrophages, and neutrophils.

Watermelon

Spinach

Spinach and other dark leafy greens are powerhouses of vitamins, minerals, and antioxidants. Spinach is an excellent source of folate, a B vitamin that helps repair DNA and aids the body in producing new cells.

Citrus

These are some of the best sources of vitamin C. Vitamin C’s link to the immune system is often debated. No matter what you believe, vitamin C is still a powerful antioxidant that protects against cellular damage.

Peppers

Another excellent source of vitamin C and also capsaicin. Capsaicin improves circulation, reduces pain and inflammation, thins mucus, and acts as an antioxidant. It has been linked to reducing the growth of some cancers too.

Broccoli

This nutrient-dense vegetable boosts immune function with sulfur compounds and supplies a ton of vitamins, minerals, and antioxidants. It’s also very easy to use in thousands of recipes.

  • Dear Charlie,
    You are doing quite a great job and with outstanding benevolence. God will increase your knowledge and strength to excel in this very rare ministry.
    I am disturbed after discovering from practical observations that most people are sick often, as a consequence of ignorance or stubbornness (Hosea 4:6).
    Unfortunately, most medical practitioners will never care to enlighten the masses during their hurried up consultations. They are often interested in these patients' losses which they call professional gains through outrageous charges, especially in Nigeria.
    I am equipping myself with facts people like you are posting, in order to have a voice that can be of great benefit to all who will desire to be healthy by nature.
    God will surely bless you. Thanks.

  • I absolutely love the Warrior Blend Vanilla Protein Powder, and the Ormus Greens. One of my favorite breakfast shakes, is Warrior Blend Vanilla, Ormus Greens, 1 Cup So Delicious Non-Dairy Coconut Milk and 1/2 cup mixed berries. On some days, I also mix in 1/4 cup dry oats.

    I co-own a gym with my husband. We are both personal trainers. I have many women that battle the issues of "no time to eat" to have sweet tooths.....I have all my girls drinking Sunwarrior Products and they all love them, that's why I am an affiliate. Most protein powders have a bad chemical aftertaste. Not these, they are delicious!! I am a huge advocate of organic eating, and getting stronger as we age, NOT dieting.....I LOVE SUNWARRIOR PRODUCTS!!
