why does greek yogurt have so much protein

It used to be that shopping for yogurt was a matter of choosing a flavor and container size. Greek-style yogurt companies have made a name for their product by touting protein-content, too. According to the U. S. Department of Agriculture's National Nutrient Database, a 6-ounce container of regular yogurt has a mere 8. 9 grams of protein compared to the 17. 3 grams found in the same serving of Greek yogurt. The manufacture of regular and Greek yogurt begins with the same process. Milk is heated and seeded with live, active cultures, including Lactobacillus bulgaricus and Streptococcus thermophilus. The bacterial cultures transform the milk into yogurt in a process called fermentation. The reason Greek yogurt has a higher protein content is that it is a much more concentrated product. After the milk has fermented, manufacturers strain the yogurt extensively to remove liquids.

The end result is much thicker and more protein-dense than regular yogurt.
Greek yogurt and regular yogurt look a little different and taste a little different. But what makes them different? And is one better or better for you than the other? What s the Difference Between Regular Greek Yogurt? {Referral links are used in this post. } Earlier this week my husband asked me what the difference is between Greek and regular yogurt. IБve had both (in fact, thereБs some Greek yogurt in my refrigerator right now), but the best answer I could come up with is that Greek yogurt has more protein and a thicker consistency than regular yogurt. But then I was stuck. Why these differences? Is it the kind of milk thatБs used? The bacterial cultures? Something in the recipe or the processing? Are there other differences? So I did some digging.

It turns out that both Greek and regular yogurts start out with the same ingredients Б milk and bacterial cultures. In fact, both types of yogurt even use the same bacterial cultures ( Streptococcus thermophilus and Lactobacillus bulgaricus, if you were wondering). These bacteria ferment the lactose ( ) in the milk and produce lactic acid. What s Different About Greek Yogurt? After fermentation, the liquid whey is strained off the solid yogurt. Regular yogurt is strained twice, so there is still some liquid left in the end product. Greek yogurt is strained three times, so most of the liquid is removed. This is what gives Greek yogurt itsБ thicker consistency and stronger flavors compared to regular yogurt. Because Greek yogurt is more Бconcentrated,Б it has more protein than regular yogurt. The protein is left behind in the solid yogurt during the straining process.

The whey contains most of the sodium, carbohydrates, and calcium, so Greek yogurts are lower in these nutrients than their regular counterparts. In fact, so much volume is lost during the extra straining step that it typically takes 4 cups of raw milk to get 1 cup of Greek yogurt, while it only takes 1 cup of raw milk to get 1 cup of regular yogurt. Here is a comparison of the nutritional value of Yoplait fat-free strawberry yogurts. While I love that Greek yogurt is higher in protein than regular yogurt, IБm not crazy about the flavor of plain Greek yogurt. ItБs too sour for my tastes. (IБm not really crazy about plain regular yogurt, either. ) I think the flavored varieties, on the other hand, are pretty awesome. Have you tried Greek yogurt before? What s your favorite way to use Greek yogurt? Enjoy!
