Yogurt is probably the best substitute for half and half that you can find. Like half and half, it is a dairy product, and because of that has the same creaminess and smooth texture. However, unlike half and half, which is loaded with fat and calories, yogurt can actually be quite healthy. Yogurt contains high amounts of calcium, which keeps teeth and bones strong, and protein, which helps to maintain muscle mass. For the best results, you may want to consider choosing a yogurt that is made from milk that is low or nonfat. While yogurt is already a healthier choice than half and half, cutting out some extra calories will only improve its health status. For a taste that is most similar to that of half and half, choose plain, unsweetened yogurt.
