Making yogurt involves fermenting milk with live cultures of beneficial bacteria.
Strained Greek yogurt is lower in sugar than regular yogurt. Removing the whey produces a thicker, creamier yogurt with a tart taste.
Some manufacturers add thickening agents to regular yogurt, and market it as “Greek-style” yogurt, which may not share the same health benefits as Greek yogurt.
Also, low or no-fat Greek yogurt may not share the same health benefits as traditional Greek yogurt.
