Greek yogurt
100 grams of plain Greek nonfat yogurt contains approximately 59 calories and 0.7 mcg of vitamin B12, which is 29% of the daily value. In addition to providing similar nutrients to milk, such as calcium, vitamin B12, and protein, yogurt also contains probiotics. Probiotic-containing foods, such as yogurt, can improve the ability of gut bacteria to metabolize food, prevent disease, and absorb vitamins.
