Nonfat plain kefir is a cultured, fermented milk drink, similar in taste and texture to a drinkable yogurt, but with distinct health benefits. It's made by adding kefir grains to milk, resulting in a rich, tangy beverage brimming with probiotics, which are known for supporting digestive health and boosting immunity. Nonfat versions offer all the benefits without the added fat, making it an excellent option for those monitoring their calorie intake. Ideal for smoothies, as a tangy addition to recipes, or enjoyed on its own, it's a versatile and health-forward choice for enhancing daily nutrition.
