When you think about foods that promote healthy digestion, dairy products probably do not come to mind first. In fact, many people believe that dairy causes constipation rather than helping with regular bowel movements. This reputation comes from research showing that proteins in cow’s milk can slow down intestinal activity, making it harder to stay regular. However, the good news is that not all dairy products have this effect, and some can actually support digestive health in significant ways.
Kefir stands out as the top dairy choice for promoting regular digestion and bowel movements. This fermented milk drink contains a unique combination of probiotics that can reduce inflammation, enrich your gut microbiome, and even improve lactose digestion. All of these benefits work together to create a healthier and more consistent digestive system. Unlike regular milk or cheese that may contribute to constipation, kefir provides live cultures that actively support your gut health.
The secret to kefir’s digestive benefits lies in its impressive variety of beneficial bacteria. By now, you have probably heard that a healthy gut microbiome, consisting of trillions of bacteria in your intestines, is essential for comfortable and regular digestion. One of the best ways to maintain a healthy microbiome is by consuming foods rich in probiotics, and kefir delivers on this front. “Kefir contains more than 30 probiotic strains, which is significantly more than most dietary supplements,” says nutritionist Alyssa Simpson. Nutrition expert Hanna Kelley explains that consuming such a large number of beneficial bacterial strains helps create a diverse microbiome, which leads to healthier intestines and better digestion.
The probiotics in kefir also help prevent constipation by making it easier for stool to pass through your system. “Probiotics from kefir soften stool and regulate the work of intestinal muscles so they move more efficiently. Because of this, bowel movements are more regular and comfortable,” explains Kelley. Although research is still somewhat limited in this area, one study showed that people who regularly consumed fermented foods experienced benefits in terms of stool consistency and the time it took for food to pass through their digestive system. This means that adding kefir to your daily routine could make a noticeable difference in how you feel.
Chronic inflammation not only increases the risk of chronic diseases but can also disrupt digestive system health and contribute to constipation. Fortunately, kefir can help calm inflammatory processes in the digestive tract, leading to more regular bowel movements. “Kefir can reduce inflammation in the intestines and thus improve the function of the intestinal barrier, and it is known that these changes promote intestinal motility,” says Simpson. She refers to a study in which peptides, bioactive compounds, and probiotic strains in kefir positively affected inflammation and intestinal permeability, which is important for nutrient absorption and preventing harmful substances from entering the bloodstream.
If you have lactose intolerance, you might think all dairy is off limits, but kefir could be an exception worth trying. While diarrhea is a common symptom of lactose intolerance, constipation occurs in approximately 30 percent of cases. If your intolerance causes constipation rather than loose stools, kefir might actually help. “Research has shown that kefir can improve lactose digestion in people who are intolerant, yet still want to take advantage of the nutritional and health benefits of dairy products,” emphasizes Kelley. This makes kefir a valuable option for those who struggle with traditional dairy.
You can use kefir in many ways, similar to yogurt, but since it is liquid, the easiest method is simply drinking it straight. However, keep in mind that it has a strong, sour taste that might take some getting used to if you are not familiar with fermented foods. If the taste is too intense for you, there are plenty of ways to incorporate it into recipes. “Add it to smoothies, homemade salad dressings, or even overnight oats to bring diversity to your intestinal flora,” suggests Kelley. Consuming fermented foods like kefir is just one step toward maintaining regular digestion, and there are several other strategies you should consider as well.
Make sure you are eating enough fiber, as it adds bulk and softness to stool, making it crucial for regular digestion. However, it is important not to overdo it with fiber consumption. “Fiber can help, but more does not necessarily mean better. Focus on the types that your intestines tolerate, introduce them gradually, and monitor your body’s reaction,” advises Simpson. The recommended daily intake is 25 grams for women and 38 grams for men. Staying properly hydrated is equally important, as dehydration is a common cause of constipation according to Simpson. For adequate hydration, aim for an intake of about 2.7 liters of fluid daily for women and 3.7 liters for men. Regular exercise also plays a significant role in combating constipation, with research showing that physical activity can be highly beneficial. Whether it is walking your dog, mowing the lawn, or an hour of dancing, finding ways to move throughout the day can significantly contribute to maintaining regular digestion.
Kefir is a fermented milk product that originated in the Caucasus Mountains and has been consumed for centuries in Eastern European cultures. The fermentation process involves adding kefir grains, which are a combination of bacteria and yeast, to milk and allowing them to culture at room temperature. Unlike yogurt, which typically contains only a few bacterial strains, kefir offers a much broader spectrum of microorganisms that can colonize the gut. The drink has a tangy, slightly effervescent taste due to the fermentation process and can be made from various types of milk including cow, goat, sheep, or even non-dairy alternatives like coconut milk. Traditional kefir also contains a small amount of alcohol, usually less than 1 percent, produced during fermentation, though commercial versions are often processed to reduce this further.
