Emerging research suggests that kefir may play a role in supporting the immune system. While more studies are needed, the probiotics and nutrients in kefir could potentially help protect your family against common infections and allergies, which is especially important for children exposed to various germs at school or daycare.
Some studies suggest that kefir may even have anti-inflammatory effects for the gut. Chronic inflammation in the gut is linked to various digestive disorders, and consuming anti-inflammatory foods can help mitigate these issues. While the internet has many people claiming that dairy foods contribute to inflammation, that is not true. In fact, research shows that just the opposite is true.

Numerous studies show that dairy consumption is either anti-inflammatory or completely neutral. A 2021 review in the Journal of the American College of Nutrition, looked at 27 trials on the effect of milk, yogurt, and cheese on inflammatory markers and concluded that consuming dairy appears to have a neutral to beneficial effect on inflammatory markers.
This 2022 review in Cureus, Journal of Medical Science, explores the evidence from pre-clinical studies that suggests potential mechanisms by which kefir contributes to immune health. It concluded that because of the variability when it comes to the make up of kefir including type of grains used, recipes, and fermentation process, further studies are needed to close existing knowledge gaps and demonstrate a consistency of results.
