All over the world, the global diet includes fast food－prepared items from inexpensive restaurants, snack bars, or food stands．Some examples of American fast food are hamburgers, hot dogs, sandwiches, fried chicken, and so on．Some types of international fast foods might be German sausage and Schnitzel, Italian pizza, Japanese sushi and tempura, Chinese eggrolls and noodles and the like．The variety of fast foods all over the world is growing．Even so, this kind of style is becoming worldwide．Fast-food places usually prepare and serve the items quickly．Many are part of fast-food chains(eating places with the same name and company owner)．For example, the biggest and most famous American fast-food chain serves hamburgers in nearly every part of the world．
For several reasons, many people choose fast food．First, it is quick and convenient．Second, it is cheaper than special home-cooked meals or formal restaurant dinners．And third, it is easy to find every eating place with the same company name．The atmosphere and style of most fast-food places is casual, comfortable, and familiar．
Why do other eaters stay away from this fast, easy kind of nourishment? The main reason is its low nutritional value．Fast food doesn’t have large amounts of fiber, vitamins, minerals, and the like-elements necessary for good nutrition and health．In contrast(相反), most types of fast food have a lot of fat, sugar, or salt in them．Possibly, these things can cause or increase health disorders, like heart disease, and some kinds of cancer．Recently, these quick and easy kinds of world wide nourishment are generally getting better and more healthful．For example, many fast-food restaurants now have put vegetable items on their menus．
Of course, human beings around the world don’t always eat in fast-food places．The variety of food choices is large now and is probably going to increase．The number of food preparation methods is growing too．Cooking customs, eating habits, and food preferences all over the world are becoming more healthful．In these and other ways, the global diet is changing．

Most American children eat potatoes．But many children don't know what of the potato is the best for food．Take a knife and cut from the middle of the potato a piece as thin as paper．Hold the piece between your eyes and light．You will see that the potato has skin(皮)，an outside rim(边缘) and an inside part．The outside rim which is right under the skin of the potato，is the most valuable part of all．But this is often thrown away with the skin．Even the skin itself is better for food than the inside．When eating a cooked potato，if you choose the inside and leave the outside，you are throwing the best part of it．If you can't eat the whole potato，eating the outside rim and leaving the inside will do．
