Nutritionist explains how to choose beneficial kefir and when to avoid it

Choose kefir with a simple ingredient list of milk and starter culture, avoiding sugar and artificial additives. A nutritionist advises against consuming kefir at night, especially for those with insulin resistance, and recommends avoiding it with severe lactose intolerance or during gastritis flare-ups. Kefir aids digestion and immunity but is not a weight-loss miracle; healthy weight loss requires a balanced calorie deficit, not restrictive diets.
