When buying yogurt, your first decision is whether you want regular-fat, low-fat, or fat-free. You probably have a favorite brand, with just the right texture or tang for your taste buds. If so, stick with it. But do check the label for sugar content. Some flavors and brands have more than others. And if you like a lower-fat yogurt, even better. There’s some question that while other components in dairy may be helpful to your health (calcium, vitamin D, probiotics, etc.), dairy fat may increase your risk of heart disease. Harvard University researchers recently analyzed data from the Nurses’ Health Study and concluded the data do suggest that a high intake of dairy fat is associated with a greater risk of ischemic heart disease in women.
