A
(2020·安徽五校质检) We humans are addicted to sugar. That makes sense. All animals need sugar to live. It’s the fuel that powers our cells. So it’s not surprising that we’re born to want the sweet stuff.
Sugar stores the sun’s energy like a battery. After a meal,
your body breaks down foods into their building blocks. It uses some sugar for energy right away. The rest get stored for the body to break down later. It’s a myth that sugar makes you extremely excited, but having a sugary snack can give you a quick burst of energy. That’s because the sugar in sweet foods is easy for your body to turn into fuel. When you eat other kinds of foods, like vegetables, it takes longer for your body to break the sugar down.
These days it’s easy to find sweet snacks. Sodas, candy, cakes and even foods that seem healthy, such as yogurt, can be packed with sugar. Food makers add sugar, because they know that to humans, sweet makes everything taste better. Americans eat about 20 teaspoons of extra sugar every day. That’s way more than what is good for us.
Eating too much sugar can cause more than a stomachache. It can make people overweight, decay the teeth and even cause diabetes. However, experts aren’t worried about naturally sweet foods—the problem is added sugar. So go ahead and enjoy sweet apples or even sugar—rich carrots that are also full of vitamins and other good stuff.
Even cake is great once in a while, as long as you don’t overdo it. After all, no one wants life to be dull. And your body needs its fuel!

willing to leave your country and explore life in other areas, there are many countries boasting an extremely cheap and low cost of living. Check out the following countries when planning your next move.
Ecuador
Ecuador is similar to the United States in many ways, and as a result has become a popular American getaway. They even use the U．S. dollar for their currency. In this country, it’s cheaper to eat out every day than cook for yourself on a budget in the U．S. You can even buy a property for around $50，000 and hire someone to tend to it while you’re away.
Mexico
Although the country is known for its poverty-ridden streets, there are many wealthier areas that provide every facility you might need. You can live off a mere $700 to $800 a month in Mexico, and this includes rent for a nice place, facilities, food, and any sightseeing.
Argentina
Argentina has been a popular tourist destination for many years. It has great restaurants, a rich history, and many places to explore. Not to mention, it’s not very expensive to live there. A decent sized home can cost around $139，000, which is relatively cheap in relation to homes in the United States.
Vietnam
Vietnam has also become a popular tourist destination in recent years. There are many million dollar luxury homes by the beach, but you can find a modest flat or small home for around $25，000 to $50，000 if you search in the right areas.
