The cost of disease and disorders of the gastrointestinal tract is in the billions. Each year, people spend lots and lots of money on digestive health ailments, more than mental health, heart disease, and trauma. Many people across the world currently have some type of digestive-related problem, with an estimated 10 to 15 percent of the adult population battling symptoms of irritable bowel syndrome. Thanks to the world’s standard diet, it’s no surprise why so many people are suffering from an imbalanced gut microbiome and poor health.
In response to common gut-related ailments, more people are turning to probiotic foods to help regulate their digestive tract and reduce gastrointestinal discomfort. Since digestive diseases are among the major illness in the world, increased consumption of probiotics in foods and supplements couldn’t be more timely. Regularly consuming yogurt, kefir, kombucha, kimchi, miso, tempeh, and other probiotic-rich foods help with regulating weight loss, improving immune function, and balancing the gut microbiota. Thanks to the unique properties of probiotic strains, the human body can greatly benefit from regularly consuming probiotics in food.
What are probiotics?
The digestive system is home to over 400 different types of bacteria. Since 70% of the immune system is found in your gut, ensuring that the microbiota is healthy and balanced is critical. Consuming fermented foods with probiotics like kimchi, tempeh, miso, and sauerkraut is highly beneficial for the body. Probiotics are used to support gut bacteria and health, treat inflammation, heal acne, promote weight loss, and curb appetite. Some people may accidentally interchange probiotic and prebiotic foods, but they are different and should not be confused as the same thing.
Probiotics and prebiotics both offer unique health benefits for gut bacteria and overall digestive health. So, what are probiotics? Probiotics are living strains of bacteria added to foods that support diverse, balanced gut microbiota. Prebiotics are plant fibers that help nourish good bacteria within the gut. Some examples of prebiotic foods include asparagus, garlic, leek, and flaxseeds. Simultaneously taking prebiotics and probiotics boosts the impact of both and is a form of microbiome therapy. Probiotics mean ‘for life’ and are instrumental in keeping the digestive tract healthy.
Probiotic foods that support gut health
One of the simplest ways to introduce probiotics to your digestive tract and support a balanced gut microbiome is to consume the best probiotic foods. When looking for probiotic fermented foods, check the label to see what specific probiotic strains are included. Eating fermented foods enrichens your diet and provides healthful benefits.
1. Greek yogurt

Typically, Greek yogurt has a lower amount of lactose than other yogurt types and contains probiotics Lactobacillus acidophilus or Lactobacillus casei. Eat Greek yogurt for a source of calcium, a reduced risk of type 2 diabetes, lowered blood pressure, and plenty of protein and potassium to keep you sated. It is recommended to consume at least one cup of yogurt daily to fulfill dietary guidelines. Eating Greek yogurt made from goat’s milk may be gentler for people who have lactose intolerance and a sensitive digestive system.
2. Kefir
If you want to enjoy the probiotic benefits found in foods that are packed with nutrition, consider drinking a serving of kefir daily. Kefir is fermented milk that contains a low amount of alcohol, is safe for most to consume without issue, and helps improve lactose tolerance. In addition to supporting gut health, kefir may improve bone health, protect against cancer, and has antibacterial properties worth investigating.
Kefir can be made using raw milk if the grains are activated. Sensitive adults should make this probiotic-rich fermented drink using pasteurized milk, which helps hydrate kefir grains.

Does eating probiotics foods have side effects?
Many people consume probiotic foods like fermented pickles or kefir with little to no adverse reaction. But, they may cause side effects when your body has to adjust to probiotic foods being a regular part of your diet. Side effects of probiotics may include bloating, gas, constipation, allergic response, and thirst. Some people may develop stomach irritations in the form of cramping or diarrhea.
Over time, any unpleasant downsides of probiotics typically subside after a few days or weeks, as your body’s digestive system and microbiome get comfortable with introduced probiotics. Probiotic foods are considered safe to consume because the bacteria and microbes within are naturally occurring in the body. Any side effects produced are a matter of the gut microbiota responding to the friendly bacteria.
How to add probiotic foods to your diet without side effects
Take things slow and steady, gradually introducing probiotic foods to your diet. Start with a low amount of probiotics and increase the amount consumed according to your body’s comfort level and response. Suppose you allow your body a few weeks to get adjusted to introducing more probiotics to the digestive system. In that case, the likelihood of experiencing diarrhea, bloating, gas, constipation, or other discomfort is greatly reduced. Consult a registered dietitian or your physician to provide medical advice regarding your probiotic intake and eating fermented foods.
Summary
Probiotic foods are a rich source of nutrients, antioxidants and they support gut health. You can enjoy the health benefits of live probiotics by consuming foods with specific probiotic strains or taking a daily supplement. When first consuming probiotic foods, the body may need some adjustment, and there may be some discomfort in the form of gas, cramping, constipation, or diarrhea.
However, gradually introducing probiotic strains to the digestive tract can help reduce health ailments and improve overall health and bodily function. As digestive problems continue to plague many people, adding probiotic foods to one’s diet provides beneficial bacteria for good health. Fruits like apples, peaches, mango, grapes, pineapple, banana, citrus fruits, and guava are good sources of natural probiotics.
All of these fruits are supportive of gut health and good bacteria. Make an effort to consume more probiotic foods, such as kefir or kombucha, for a refreshing drink. Tempeh, probiotic yogurt, and miso can be eaten alone or added to dishes. Probiotics are different from prebiotics. Prebiotics describe fiber found in foods that nourish good bacteria within the gut. Probiotics are used for describing bacteria in supplements and certain types of foods that have health benefits.
