Understanding a Healthy Immune System

Supporting the immune system is not about taking one supplement or avoiding certain foods. There is no quick fix. It’s about a comprehensive strategy to provide your body with what it needs to function at its best.

Poor diet, stress, lack of sleep, and too little exercise all have an effect and can lower the body’s ability to fight infections and viruses.

Along with nutrient-dense foods that help the immune system to be strong, there are other dietary and supplement considerations.

Here are five key strategies to help support the immune system:

  1. Eat a balanced diet to support the health of the immune system and the gut and to help lower inflammation.
  2. Take supplements that help the immune system fight pathogens.
  3. Exercise.
  4. Implement stress management techniques.
  5. Make sleep a priority.

There are many options listed below. Don’t be overwhelmed. Just start with simple suggestions you know you can implement and then add what you can to build a complete strategy. This will serve you well both now and for years to come.


When the immune system fights pathogenic bacteria or viruses there are many elements in its arsenal to neutralize the problem. Inflammation, either localized or throughout the body, is part of the tools your immune system uses to help fight anything it sees as harmful to you. Sometimes it’s wrong, as in the case of allergy or autoimmunity. And sometimes it’s right, as in the case of viruses and pathogens.

Too much inflammation can cause severe damage. For example, if there is too much inflammation in the lung, breathing can be impaired, which can be life-threatening.

Controlling inflammation is also important. Many people are chronically inflamed. Should they contract a virus or bacterial infection, even more inflammation is going to occur, increasing the risk of a serious outcome.

Gut Health

The gut, and the good bacteria that reside there, is a major player for a healthy immune system. You can’t be healthy without a healthy gut. Unfortunately, it’s complicated, but there are foods and supplements that can help, and working with a health practitioner can help should you need a more comprehensive strategy.

What Can You Do to Support Your Immune System?

Eat a balanced diet to support the health of the immune system and the gut and to help lower inflammation.

Add more nutrient-rich fruits and vegetables. Variety is the key, as well as healthy proteins that provide amino acids, the building blocks of the immune system. Complex carbs like grains and legumes provide substantial energy that the body needs to function properly. Vitamins and minerals are catalysts for all body functions, especially the immune system.

Nutrients the immune system loves (and these are just a few suggestions:

Ideally, you should choose to buy organic. Lowering your exposure to toxic chemicals is just one way to lower inflammation and take some pressure off the body and the immune system. Do the best you can.

  • Essential Fatty Acids: Found in chia, flax, hemp, cold-water fish such as salmon and tuna, butter, eggs, raw nuts, and seeds
  • Vitamin A-rich foods: Eggs, butter, cod liver oil, sweet potatoes, carrots, tuna, squash, spinach, and other green leafy vegetables
  • Vitamin C–Rich foods: Citrus fruits, carrots, kiwi, bell peppers, tomatoes, strawberries and other berries, broccoli, cabbage
  • Vitamin E-rich foods: Olive oil, avocados, sunflower seeds, walnuts, salmon, turnip greens, mangos
  • Vitamin D-rich foods: Cod liver oil, salmon, mushrooms, milk or fortified milk substitutes, eggs
  • Zinc-Rich foods: Meats, lentils and legumes, dairy products, vegetables, oysters, sesame seeds, cashews and other nuts, legumes, chocolate and cocoa, baker’s and brewer’s yeast

Lowering Inflammation

Consuming foods that have been studied to have anti-inflammatory properties is a good idea:

  • Omega 3-rich foods such as cold-water fish like salmon and tuna, chia, hemp, flax
  • Herbs and spices: Turmeric, ginger, cinnamon, garlic, cloves, black pepper, cayenne pepper, sage, rosemary, basil, peppermint, coriander, cilantro/coriander
  • Many vegetables have phytonutrients that are anti-inflammatory: Tomatoes, eggplant, peppers, broccoli, cabbage, Brussels sprouts, kale, bok choy, carrots, cauliflower, asparagus
  • Many fruits have anti-inflammatory phytonutrients: Berries, pineapples, papaya, citrus fruits, apples, cherries, avocado, sea buckthorn
  • Hemp oil extract or full-spectrum CBD oil – has anti-inflammatory properties

Gut Health

The simplest way to start is to feed the gut the food good bacteria loves and remove the food it doesn’t. Fortunately, good bacteria, just like the immune system, love foods that are full of nutrients. That’s not a coincidence. Adding foods that contain good bacteria also helps.

Here are some examples of foods that help the gut:

Probiotic and/or Fermented Foods: Contain good gut bacteria that affect the adrenals, the thyroid, the liver, and how our hormones function

  • Cultured vegetables, miso, tempeh, sourdough, sauerkraut, kimchi, kefir, yogurt, kombucha, wine (red or white), unpasteurized beer
  • Raw honey contains ten strains of good bacteria and has antimicrobial properties
  • Fermented foods also contain prebiotics, so win-win.

Prebiotic Foods: Feed our resident good bacteria and aid good gut bacteria

  • FOS and inulin foods: Jerusalem artichokes, chicory, garlic, onions, dandelion greens, asparagus, bananas, blueberries, almonds, broccoli, cabbage, kale, cauliflower, radish, chia, flax, tomatoes
  • Pectin foods: Apples, pears, lemons, limes, oranges, grapefruit, kiwi
  • GOS foods: Dairy products, legumes
  • Resistant starch foods: Wheat, rye, spelled, Kamut, barley, oats, corn, brown rice (and cooled white rice), potatoes, sourdough, quinoa, sweet potatoes

Supporting other aspects of the gut

Bone broth provides amino acids that help the intestinal wall lining. Colostrum, aloe vera, and collagen also help nourish the gut lining, and all have some anti-inflammatory properties.

Ode to Mighty Mushrooms: Mushrooms are immune system stars. They have antimicrobial and anti-inflammatory properties. Plus, they are all prebiotics, so they feed good gut bacteria. They’re available both fresh and dried (be sure to rehydrate dried by soaking in water for 30 minutes). Extract powders can also be added to recipes and smoothies or made into teas and supplements. Several companies have created products that contain several types of mushroom combinations and are available as a tea or liquid extracts.

Take supplements that help the immune system fight pathogens.

For the Gut: Probiotics, glutamine products or formulas, plant sterols, antimicrobials such as oil of oregano, aloe vera or grapefruit seed extract, essential oils such as clove, cinnamon, thyme, or lavender. Note: If ingesting essential oils, make sure they are food grade and mix with a carrier oil such as coconut oil.

What is an antimicrobial supplement or food? There are many supplements that contain phytochemicals that are known as antimicrobial. This means they have the potential to help the immune system fight pathogenic bacteria and viruses. They help “inhibit,” not “kill.” They can be useful for helping to eliminate excess pathogens and do not harm good bacteria.

Immune System Supplements: These supplements are misunderstood because they’re often called “immune boosters.” Many assume this means they will make the immune system more active, and in the case of inflammation, more will be produced. This is not accurate, and the correct term is “immune balancers.” They can be very helpful to the immune system in fighting pathogenic bacteria and viruses. They do not harm good bacteria.

Examples of immune-support supplements include elderberry, echinacea, astragalus, plant sterols, garlic, and algae such as chlorella or spirulina.

Exercise improves circulation and allows cells and the immune system to function better.

  • Go for a walk if you can, and if you like to jog, then do that too.
  • Look for apps or YouTube videos for exercises you can do at home.
  • Purchase a DVD online for yoga, Pilates, or any other type of exercise that appeals to you.
  • Get up frequently if you are sitting a lot and just walk around your house or apartment for a few minutes.

Implement stress management techniques.

Some stress can be helpful for the immune system and inflammation. Too much stress can use up valuable nutrients that are needed by the immune system in other areas of the body. Even if you feel really stressed for periods of time during the day, it’s important to find ways to relax and calm the adrenal glands down and lower the stress hormone cortisol.

Here are some ideas:

  • Take regular breaks from the news or your work.
  • Distract yourself: Call friends or family and have a good chat. Watch a favorite movie or one that makes you laugh.
  • Practice meditation or mindfulness – there are YouTube videos and online apps that can help if this is not something you currently practice.
  • Listen to your favorite music; sing along and dance if you like.
  • Exercise.
  • Make time for your favorite hobbies.
  • Take an adrenal supplement – there are many. Look for them online or ask at your health food store. Talk to a health professional for more advice.

Make sleep a priority.

The immune system needs the time you sleep to repair and regenerate itself.

Here are some tips:

  • Lower stress - it can keep you awake at night.
  • Go to bed at the same time every night and get at least 7–8 hours of sleep.
  • Try to create a proper sleep environment with a completely dark room and no sound distraction. Sleep masks and earplugs can help where necessary.
  • Avoid caffeine or eating a large meal close to bedtime. Some people cannot sleep on an empty stomach, so a light snack such as a piece of fruit or a few nuts is acceptable.
  • Disconnect from electronics like computers, cell phones, and even TV at least an hour before bedtime.
  • Read a book, take a warm bath or practice some deep breathing or relaxation exercise before bedtime to quiet the mind and prepare the body to fall asleep more easily and get better-quality sleep.
  • Consider taking an herbal sleep formula or magnesium, if needed, to help you relax so that you can have a better sleep.

These are just a few suggestions. Think about these and implement what you can. Then build on these habits so that your immune system can stay strong.
