Best Natural Immune System Boosters – It’s All About Your Gut!

I bet you didn’t know that over 70 percent of the cells that make up your immune system are located in the lining of your stomach! Your digestive system is actually one way that your body rids itself of toxins.  In order to keep your immune system functioning optimally, eating clean, eating more fiber and taking  probiotics and other targeted supplements are necessary.  Doing these things will promote the growth of friendly bacteria in the gut.  A healthy microbiome is critical to health of your immune system because it is protective and healing to the lining of the gut.  This article will explain some of the best natural immune system boosters to keep your gut healthy and functioning optimally.

Keep The Good Bacteria!

One of the best things you can do for yourself is to keep the good bacteria in your gut.  One of the leading causes of good bacteria being wiped out is fluoride in tap water.  If you drink tap water you must filter your water.  Another source of declining good bacteria is antibiotics.  Antibiotic use is one of the major reasons our digestive systems have a major imbalance of good to bad bacteria.  Sugar doesn’t kill off good bacteria, but it causes bad bacteria to grow more.  Sugar is a no-no when you are trying to boost your immune system.

Probiotics In Your Food.

When you need to increase the good bacteria in your gut, the most important thing to do is eat probiotic food and take probiotic supplements.  Common foods that are full of probiotic goodness:

  • Kefir
  • Kombucha
  • Kimchi (fermented vegetables) and sauerkraut
  • Probiotic yogurt
  • Natto (fermented soybeans)
  • Raw milk
  • Soluble Fiber. Foods like apples and sweet potatoes are chock full of soluble fiber.  Soluble fiber heals the lining of the stomach and as a result, boosts immunity.


Increasing these kinds of foods will help boost your immune system by increasing the good bacteria in your gut.  When the ratios of good to bad bacteria are in balance, the lining of the gut is strong and healthy leading to increased immunity.

  1. What a great article! I’m a big fan of probiotics.

    While reading this I couldn’t help but think about the last child my wife and I had. He had horrible colic for about the first 3 – 4 months. The only thing we found that actually seemed to make a big difference in his comfort level (and subsequently ours) was giving him daily probiotics.

    Thanks for the informative read! 🙂

    1. Thanks Christian! It’s no surprise that your baby did well with probiotics. Emerging research is showing us that our babies microbiome is populated after delivery, not in the womb. So any external factors, including cesarean section, can alter the formation of the diversity of good and bad bacteria!

  2. I think I may be in a bit of trouble…all I drink is tap water unfiltered and I have a terrible sweet tooth! Plus, I haven’t heard of about half of the foods on your healthy probiotic food list. But good thing I know now, so I can try to chnage some things. How do you know if you don’t have a healthy gut? Do you just get sick easier/more often?

    1. Hi Summerly! The good news is that you can change the diversity of your gut bacteria with lifestyle changes. If you have a healthy gut, you don’t have sensitivities, bloating, gas, stomach issues, allergies, colds and flu and other illnesses. As you get older, your microbiome (gut bacteria) will change due to the abuses of youth. LOL! So now is a great time to start incorporating those foods and taking a daily probiotic! Thanks for writing!

  3. Wow, I didn’t know how much bacteria we were actually putting into our gut until I read your article. So thank you so much for this. I also didn’t even have a clue about Probiotics, now I know how to have a healthy gut. Actually I’m going to send this page to my partner right now, I know she’ll enjoy the read.

    Great article, thanks for being so honest!


  4. Thanks Brandon! It’s never to late to get healthier. Your gut bacteria is emerging to be an important factor in our physical and mental health, so it’s great to be informed! Thanks for writing!

  5. I can attest to getting probiotics on the regular. I do my best to eat chobani yogurt everyday and since getting that, my body can’t let me go back to the cheaper, sugary yogurts. I just can’t do it.

    Thanks for the info about the sugar! I tend to get raw sugar, but lowering the amount of intake is a good way for me to just wean it off. I know some sugar is okay, even if it’s naturally in foods, like fruit for instance, but…At this point I might as well.

    Would you also say that when you eat certain foods or the order in which a person eats them plays a role in good versus bad bacteria? For example, I’ve heard before that drinking while eating is not good, but sips are okay, while taking a swig before or after is more ideal to let good bacteria work.

    1. Hi Dawne and thanks for your reply. Fruit is a great source of natural sugar and because the sugar accompanies all the nutrients and fiber of the fruit, it’s the perfect way to indulge your sweet tooth without worrying about negative effects of sugar. There are no studies that show the timing of food will alter your gut bacteria, but drinking water with your meal has been thought to interfere with the acid production that assists with digestion. It’s a good idea to drink your liquid after your meal or a half hour before. Great question!

  6. Well, I guess I’m totally probiotic illiterate, since I didn’t even know that all those foods had useful bacteria. It’s a good thing I found your post in that case. I’m gonna have to start incorporating these foods into my diet, and maybe start using a filter, tap water really is that bad. Thanks for your help!

    1. Thanks for your comment Mohammad. I’m glad you are considering a filter because that is very important for your health. When you try the foods with probiotics, let me know how you’re doing!

  7. Great article Linda! Gut health is SO important and I’m a big fan of probiotics……I need to start adding a little more fiber to my diet though. Thanks for sharing your thoughts with us!!

  8. Love your site! Seems like the older I get the more issues with my gut I seem to have. I’ve tried a number of your ideas and they’re all very beneficial. Thanks for sharing the good stuff with us all.

    1. You’re welcome, Cary. It’s so true, as we get older, digestion slows down a bit. There are so many things including what I wrote in the article that affect the balance of gut bacteria and aging is one more thing. It’s natural that the proliferation of gut bacteria naturally wanes with age, unless you keep your diet filled with healthy foods as the article suggests, plus reducing or eliminating if possible OTC medications.

  9. Increasing immunity is very important, considering the various diseases in the world today like malaria, chickungunya and so on. Eating foods that build the immune system is the best way to build the immune system, especially those of our children and seniors. I will certainly take into consideration the foods you recommend. Thank you
