We came across this great article in the Better Homes and Gardens, June 2013 issue, which gives a little insight into choosing the right Greek yogurt. Besides the health benefits such as reducing LDL cholesterol, preventing hypertension, Greek yogurt is high in protein, probiotic, and low calorie and sugar snack (if you get the plain flavor.) According to the article, not all Greek yogurts are made equally.
Greek-style yogurt is made by straining out the liquid whey, lactose and sugar, which gives this yogurt a creamer, thicker consistency. “But some brands achieve that texture with fillers like gelatin, cornstarch, or milk protein concentrate.”
The article also mentions that “some brands of yogurt are treated with high heat to prolong their shelf life, a process that kills beneficial microbes.” Look for brands with the “Live & Active Cultures” seal, because the U.S. Food and Drug Administration now requires a disclosure on those varieties that have been “heat-treated after culturing.”
So please look at the labels in selecting your Greek-style yogurt, you may not be getting what you pay for.
