A. Health & Nutrition Letter Editor Irwin H. Rosenberg, MD, says he enjoys traditional Greek yogurt made with whole milk. First of all, traditional or authentic yogurt made with traditional cultures with a long history may sometimes be richer in probiotic content, he says. These traditional yogurts also generally use less sugar or other sweeteners. Greek yogurt means that it has been strained, so that it is more firm and contains less whey. Keep an eye on whats added to your yogurt, however its made; if the ingredients list reads too much like a sundae, those additions will likely outweigh any health benefits from the yogurt itself. Traditional yogurt is usually made with whole milk, and there is no evidence that low-fat yogurt is healthier per se.
