    It is amusing that yogurt, which was invented to make milk last longer before the days of refrigeration, now makes grocery shopping last longer. Full-fat, or nonfat? Greek, or regular? 1.

A key recommendation when it comes to fat is to choose low-fat or fat-free yogurt. That's because dairy fat is mostly saturated (饱和的), the type linked with increased risk of heart disease. Besides, full-fat dairy has more calories than nonfat.

This view, however, has been challenged by a few recent studies. Researchers think that full-fat dairy might offer some as-yet-unknown health benefits. It might also help with weight management because the fat in it makes it more satisfying, helping keep our appetite in check.

2. Until there are further findings, it might be wiser to choose low-fat or fat-free yogurt and add healthy fat by topping it with nuts.

3. Many of them also have a hard time deciding whether to buy Greek yogurt or regular yogurt. Greek yogurt, which was rare about a decade ago, dominates the store shelves with dozens of flavors today. It has become popular partly because it features a thick, creamy texture (口感) and contains more protein and less sugar than regular yogurt.

Greek yogurt has these qualities because of its unique liquid-removing process. Unfortunately, lots of nutrients, including calcium (钙), are sometimes drained, too. Therefore, thickened yogurt and regular yogurt offer different nutritional benefits. 4.

Finally, it is worth mentioning that it's the added sugar, not the naturally- occurring sugar (which is removed in Greek yogurt), that should be the cause of our concern. Fruit-flavored yogurts that appear to be healthy may have little actual fruit and plenty of added sugar instead. 5.

A.Consumers, however. are not confused only about fat.

B.Mixing them up and enjoying both might be a good idea.

C.With so many conflicting headlines about fat these days, it's no wonder people are confused when buying dairy products.

D.Our best bet might be to buy plain yogurt and sweeten it ourselves using fresh fruit.

E.There are so many choices that we often find it hard to decide which yogurt to buy.

F.They're naturally ''packaged'' with so many important nutrients that it would be misguided to avoid them.

G.Yet more research needs to be done for us to fully understand dairy fat’s health impact .
