Kefir grains are edible and contain beneficial nutrients and live probiotics. They are primarily composed of proteins, beneficial bacteria, yeast, polysaccharides such as kefiran, and provide minerals like calcium and phosphorous[3]. Eating kefir grains can contribute additional probiotic diversity beyond what is present in the finished kefir drink, as they contain a unique matrix of lactic acid bacteria and yeasts[5].
Consuming kefir grains may offer extra health benefits, including the anti-inflammatory and immune-boosting effects attributed to the polysaccharide kefiran present on their surface[5]. However, some individuals may experience digestive discomfort after eating them, as their texture can be tough to digest for some people[1]. Recommendations generally suggest starting with small amounts to assess tolerance and, if desired, using them as a topping or spread similar to soft cheese[5].
Kefir grains do not contain gluten and are not related to cereal grains, making them safe for gluten-free diets[7]. The fermentation process with these grains also enhances the nutritional content of milk by producing additional vitamins and bioactive compounds, improving nutrient absorption[2].
