No time to eat your breakfast? Drink it! This cultured dairy drink is like yogurt only better. While both kefir and yogurt contain probiotics, the live bacteria shown to enhance digestive health, kefir can sport as many as 12 different probiotic strains compared to anywhere between 2 to 5 in most brands of yogurt. Plus kefir is cultured for 5 to 8 times as long as yogurt, giving those beneficial bugs more time to grow and multiply. Sip one of the many flavors of Lifeway Kefir on its own or blend it with fresh or frozen fruit in a smoothie. One cup of plain low-fat kefir delivers 30% of your daily dose of calcium and a hefty 11 grams of protein for only 110 calories and 2 fat grams.
