Best Foods For A Healthy Gut
A healthy gut is influenced by the foods we eat daily, among other factors. Research reveals that our gut microbiome is made up of trillions of microorganisms with over 1000 different bacteria species varying from a person to a person’s gut flora.
It is crucial to have a diversity of gut bacteria if we are to keep healthy. Research reports that our microbiome started to form as soon as we were born and is influenced by genetics, the environment we live in along with what we eat, and lifestyle, among other factors.
According to research, there’s a large number of bacteria in the human gut microbiota that can be found anywhere else in the human body such as the skin, genitals, mouth, etc. There are friendly bacteria also referred to as commensal bacteria that contribute to a healthy gut and unfriendly bacteria that cause disease in the intestinal tract.
We are what we eat. This statement holds in the sense that our food choice can either “feed the good bacteria which in turn shield us from invading pathogens or can weaken our defense system and expose us to disease-causing bacteria”.
Processed foods are thought to be detrimental to gut flora as they lack fiber and polyphenols which contribute to a healthy gut and are thought to reduce the diversity of gut bacteria
“Western dietary patterns containing large amounts of processed foods might create an imbalance in the gut system by affecting gut bacteria and their metabolism”
Exercise is good for the gut microbiome and boosts health. “Recent studies suggest that exercise can enhance the number of beneficial microbial species, increase microfloral diversity and improve the development of commensal bacteria”
Gut microbiota is said to be a complex subject and research is ongoing. ”
That said, not all bacteria are bad and this goes to show that our lives are not fully functional without a good balance of gut bacteria. If we feed them the right kind of stuff, they will, in turn, take good care of us, as far as research is concerned.
Let’s unpack what foods contribute to a healthy gut and other factors associated with a healthy gut
Foods For A Healthy Gut
These are some foods that may promote a healthy gut. Each person’s microbiome is distinct, some may have an allergic reaction to certain foods while some may not. You may have to choose what works for you.
- Yogurt
- Kimchi
- Kefir
- Tempeh
- Kombucha
- Miso
- Souerkraut
- Banana
- Blueberries
- Almonds
- Garlic
- Onions
- Oats
- Asparagus
- Legumes
- Broccoli and other greens
- Chickpeas
- Artichoke
- Brown rice and other whole grains
Probiotics And A Healthy Gut
Probiotics are live bacteria found in fermented foods and are good for a healthy gut and overall health. They are found in supplements as well.
As mentioned above various microbial species are living in the human gut. Different bacteria perform different tasks and they collectively, maintain a healthy gut and overall health. Diversity of gut bacteria is key for an all healthy gut.
“Research is ongoing into a relationship of the gut microflora to disease. The health benefits of the currently available probiotics and prebiotics have not been completely proved” Mayo Clinic.
The overuse of antibiotics can compromise the human gut bacteria. According to research the use of antibiotics heavily disrupts the ecology of the human microbiome. Processed foods such as too much sugar and saturated fats can be counter-productive to the gut microbiome.
Research shows that “prebiotics may be ineffective and possibly counter-productive in restoring the baseline of gut microbiome after it has been altered by antibiotic treatment”
Foods Containing Probiotics:
- Yogurt is the best source of probiotics. It has healthy bacteria such as bifidobacteria and lactobacillus due to fermentation. Yogurt has many potential health benefits according to research “Frequent consumption of yogurt has shown to improve risk factors for cardiovascular disease, to lower diabetes risk, enhance development for host immunity and to lower the risk of symbiosis and chronic kidney disease.
- Kefir is a source of prebiotic, a product of fermented milk and kefir grains. The drink originates from Europe and Russia and can be made from cow, goat, and sheep milk.
- Kimchi is made with fermented vegetables especially cabbage. It’s a Korean spicy side dish and a good source of probiotics. It is rich in vitamin C, fiber, and other nutrients.
- Kombucha is a fermented black or green tea, commercially sold or home-brewed. Kombucha is a good source of probiotics. It is said that “Kombucha has various health benefits, such as treating arthritis, aging, anorexia, diabetes, among other ailments but there’s no evidence supporting these claims”
- “Drinking Kombucha can be harmful to people with pre-existing ailments due to its microbial sourcing and possible none sterile packaging. Kombucha is not recommended for people with the poor immune function”.
- Souerkraut is an excellent source of probiotics. It is rich in vitamin C, fiber, vitamin K and other nutrients. It is a finely cut raw cabbage with a sour taste due to lactic acid produced by lactobacillus bacteria during the fermentation process.
- Sourdough bread (dough) is made with lactobacilli bacteria and yeast which are naturally occurring during fermentation. The lactic acid produced during fermentation provides a sour taste to the bread. The bread is packed with good bacteria beneficial to gut health.
- Miso is a thick paste used for sauces etc. It’s derived from fermented soybeans and is commonly used in Japan. It’s packed with several nutrients, minerals and also high in protein. Miso is beneficial to a healthy gut due to the bacterial environment it elicits.
- Sour Porridge it’s an African staple, commonly used for breakfast after fermentation. It is a byproduct of sorghum, whole grain.
- Tempeh originates from Indonesia and is made from soybeans through the fermentation process. It has a nutty and/or earthy taste and is rich in protein, dietary fiber, and vitamins.
According to research, the consumption of probiotics found in fermented foods is found to cause significant positive improvements in balancing intestinal permeability and barrier function
Prebiotics And A Healthy Gut
Not all fibers are prebiotics, but most prebiotics is fibers. Prebiotics are nondigestible compounds, meaning that the human body lacks the enzymes that can digest most of them. They are then broken down by bacteria in the gut. Prebiotics and fibers enhance gut bacteria thus contributing to well-being.
Foods Containing Prebiotics
- Bananas
- Garlic
- Oats
- Asparagus
- Broccoli and other greens
- Blueberries
- Lentils and other legumes
- Artichoke
- Chickpeas
- Onions
Dietary Fiber And A Healthy Gut
Some dietary fiber is also prebiotics. There are different types of dietary fiber, soluble, and non-soluble. Soluble fiber is digestible whereas nonsoluble fiber is not digestible as the human body lacks the enzymes that break them down.
They are then subjected to bacterial fermentation, influencing the gut microbial composition and their metabolic activities, according to research. It helps to eat diverse whole foods to get different types of fibers and expand the diversity of your gut flora. For more details about fiber-rich foods click here
Research shows that an increased dietary fiber intake (depending on an individual RDI) and whole grains enhance the diversity of gut bacteria. The US, compared to other countries worldwide, is said to be the lowest in terms of fiber intake.
This leads to an impaired gut microbiome and causes an increased risk in chronic non-communicable diseases, like obesity cardiovascular disease, type 2 diabetes, and colon cancer, which are prevalent in the US.
Stress And Gut Flora
Experts reveal that there’s a strong connection between the brain and digestive system and that stress can impact the gut flora and cause disturbances in the gut.
“Early life stress can change the development of the nervous system as well as how the body reacts to stress. These changes can increase the risk for later gut diseases or dysfunction ” says the American Psychological Association.
Research indicates that stress can alter the gut microbial population thus influencing neurotransmitters mediated by microbiome and gut bacteria barrier function and that meditation can help regulate the stress response and suppress chronic inflammation states maintaining a healthy gut barrier function.
Final Thoughts
According to research, the human gut microbiome is composed of trillions of microorganisms with nearly 1000 bacterial species genes, and stress can alter the gut microbial population and weaken the immune function, and influence metabolic activities and ultimately our physical and emotional well-being.
It is said that ingesting foods containing probiotics, prebiotics and fiber can promote a healthy gut and overall health.
Exercise is also thought to enhance the “diversity of the microbial community in the human gut while the overuse of antibiotics and processed foods can change the gut flora composition and make us vulnerable to disease-causing bacteria”.

Hey Maggie,
Excellent post. I have been looking for some exercise tips, which I found. I have just came across your article and I now have great tips on how to improve my diet.
Fruit and veg is the main thing I need to increase in my diet, and I need to cut out the fast foods. I’m going to try more greens as you recommend. I’ll let you know how my diet is going following your advice.
Thanks for sharing, and keep up the great work.
Tom

Hi Maggie,
Thanks for such a detailed and insightful post! I have problems with my digestion and have just started researching the gut microbiome. It’s a fascinating area and there is so much to learn! It’s really helpful to have a list of foods that are good for the gut. Luckily I love yoghurt 🙂
Hi Abby
Thank you for taking the time and reading the article. I’m glad that you found it useful. I love yogurt too especially plain yogurt and then add fruits like blueberries or other berries along with nuts.
Have a lovely day
Maggie
Hi Maggie,
Loved this post, really informative and put things in perspective for me, so thank you!
I recently started to include a lot more yoghurt into my diet after getting bloated on occasion and it has stopped that from happening, so I try to include it in my diet several times a week as a new routine. Was great to see that you have put this on your list and replenishing gut bacteria is so important.
Look forward to reading more.
Jessica
Hi Jessica
I’m pleased to learn that you found this article useful and you resonate with some of the stuff mentioned in the article. Have a lovely day.
Maggie
Great information about healthy life, thanks for thr wonderful information, I love yogurt and now I learned a lot about yogurt – Yogurt is the best source of probiotics. It has healthy bacteria such as bifidobacteria and lactobacillus due to fermentation. Yogurt has many potential health benefits according to research “Frequent consumption of yogurt has shown to improve risk factors for cardiovascular disease, to lower diabetes risk, enhance development for host immunity and to lower the risk of symbiosis and chronic kidney disease. What a great information for me, thanks for the post.
Thank you Laori
Nice article. Didn’t realize that some of the foods mentioned are good for healthy guts. Very informative. Keep up the great work.
Thank you Cynthia.
This is a superb article. Thank you Maggie. It’s nice to know that for the greater part of my diet I am doing the right things. Having lived in Germany for a long time, I was surprised to know that sauerkraut is on the good for us list – that’s great, I love it although I must admit that I was also surprised because it’s often found in tins. I often thought that it must be a processed food. The links to your research are excellent. Thank you. It’s always a pleasure to read well-researched articles and especially ones that are good for health. Talking about tinned foods . . . I saw recently that orange juice in cartoons may have a negative impact on health. Do you think the same might be true for tinned foods?
Hi
Thanks for a very positive comment. You have asked a very important and great question. Canned foods are nutrition dense more so because they are mostly legumes, fruits and vegetables among others but one needs to be cautious of the added sugar and salts that they normally contain. Which is why it helps to always check the food labels on the packaging. One more thing about Canned foods is a chemical called BPA found in canned foods which might not be good for health. Allow me to do more research about Canned foods hopefully it will feature in my next article. Thanks for raising this question. It is highly appreciated.
Have yourself a blissful day.
Maggie
This is such a great post, I have been looking for something like this for quite some time. The water in my town in SA is terrible due to the municipality not maintaining well. So it is better for us to buy water when we can. I think the water issue is something which affects the gut often. I will be adding more of these foods to my families diet too to help. Thank you again.
Hi Kay
You are welcome. Yes, We need to take precaution as to what we ingest or drink in order to maintain a healthy gut environment and exercise good hygiene practices in the environments we live in. Thank you for stopping by and reading this article.
Have yourself a great day.
Maggie
A very good article with great information in it. I’m glad I came across this article because I’ve needed to improve my diet and add some exercise also. Thank you for giving a list of food that will help improve the gut. With this information, I feel excited to get started.
Hi Lyde
You are welcome. I’m glad that you found this article helpful. Wish you all the best with improving your diet.
Maggie
Thank you for this very insightful piece.
I was just looking for information related to gut health for my son, who has severe eczema and I think it is somehow related to a leaky gut. We are taking miso in our diet, and we take care not to cook it so as to keep the maximum amount of nutrients and good bacteria. We just mix it into the soup after turning off the heat.
He can’t take blueberries, though. Makes his skin itch a lot, I think it’s the phenols or something.
Hi Joo
Thank you for reading this article and finding it useful. About your son it will help if you see a health care or dietician to help with a suitable diet for him given his condition.
Maggie
It is a very well written and well-documented article. I am happy I came across it. Thank you for the lists of food, that’s exactly what I was looking for. I’ll stick them on my fridge door!
Thanks for your help!
Thank you for your reply Floriane. Im glad my article was of help to you.
Wish all the best
Really great post – just came off antibiotics for an ear infection. I haven’t been feeling right for a while since. Even losing weight when I didn’t want to. You just reminded me of the importance of a healthy gut. Headed to the store to check out some prebiotics. Hadn’t thought of fruits and veggies containing prebiotics. Thanks…
You are welcome. I’m glad you found the article useful.
Really a great list of food choices for better digestion.
Probiotics are essential!
When I was first starting my career in health and fitness I remember an instructor saying one time listing the 3 supplements she felt was the most important.
Fish Oil, A multivitamin, and Probiotics.
That’s always stuck with me and I’ve shared that knowledge with many clients.
The list you provided are great sources for healthy food that will naturally aid in getting a “healthy gut”
Hi Lee
Thank you for your input and for sharing your experience with probiotics. I do appreciate it.
Hi Maggie, Good to know which foods should be teken daily for healthy gut. Would you have any advice in what amounts we should take them?
Hey Angelique
Thanks for stopping by. To answer your question I wouldn’t know exactly how much priobitic food sources you need to ingest daily as there are no recommended guidlines regarding that. For further understanding kindly check out this link: https://www.health.harvard.edu/staying-healthy/how-to-get-more-probiotics
Let me know if this answers your question.
Thank you
Maggie
