More research is necessary to understand if this finding also applies to humans. However, scientists are still learning how this works.ДЄn animal study in 2018 found that kefir supplementation can improve the ratio of good to harmful bacteria in the gut and reduce physical fatigue during exercise in mice.

This may mean they can help with maintaining a good balance of species. Probiotic foods contain some of the same beneficial species of bacteria that live in the digestive tract. Some of these species have beneficial effects on the body, while others can cause harm. The gut contains many species of microorganisms. They may also affect how the body produces, processes, and uses cholesterol. The probiotics in kefir may play a role in how much cholesterol the body absorbs from food. Participants who consumed four servings per day of low fat milk also had lower cholesterol levels. The participants drank either two servings a day of low fat milk, four servings a day of low fat milk, or four servings a day of kefir.ДЄfter 8 weeks, those who drank kefir showed significant decreases in their total cholesterol levels, and in their low-density lipoprotein cholesterol levels, compared to those who drank only two servings per day of low fat milk. Lowering cholesterolДЄ 2017 study looked at changes in cholesterol levels among females with obesity or overweight who drank low fat milk or kefir. However, larger-scale research is necessary to support this. It may modulate diabetes-related markers. Participants who consumed kefir had significantly lower fasting blood sugar levels than those who consumed conventionally fermented milk.ДЄ 2020 review suggests that kefir could have a range of benefits for people with diabetes and obesity. Research into kefirвЂ™s health benefits is still in its early stages, but some evidence suggests it may help with: Blood sugar controlДЄ small 2015 study in Iran compared the effects of consuming kefir and conventionally fermented milk on blood sugar levels in people with diabetes.
