①Sugar-free cookies, reduced-sugar cereal, sugar-free candy, diet soda. Do these seem like healthier alternatives (替代物)? After sugar became something forbidden in the nutrition and fitness world, sugar-free products acted as alternatives for once beloved sweet drinks and snacks. Claiming to be ZERO sugar, they were believed as healthier choices, especially for those people who manage diabetics (糖尿病), or aim to slim down. But the truth is they aren’t equal to better.
②When a product is labeled sugar-free, it means artificial sweeteners are used instead of real sugar. Artificial sweeteners don’t come from natural sources but they are chemical substances that are added to food and drinks to make them sweeter. Actually, most artificial sweeteners are a lot sweeter than sugar, even 200—600 times sweeter, so only a tiny amount is needed.
③Let’s find out how artificial sweeteners work. They work similarly to regular sugar by exciting your taste buds. The taste buds send signals to the brain that they have tasted something sweet and you feel a similar sense as you would with sugar.
④In recent studies, scientists have revealed artificial sweeteners are more harmful to our body than real sugar. Many businesses market sugar-free alternatives as “low-calorie” or “no-calorie”. It misleads people to believe sugar-free products can make them slim and healthy. But it’s reported that you get no nutritional value from consuming them.
⑤What’s worse, when you eat this kind of sweet food, your body continues to desire it even though your body can’t metabolize (新陈代谢) these sugar-free alternatives. Your brain does not know the difference, either. In turn, sugar-free alternatives connect to weight gain and Type 2 diabetes.
⑥Similarly, artificial sweeteners also damage your gut’s ability to break down sugar which affects everything you eat. In other words, your body doesn’t know how to deal with artificial sweeteners because they have nothing real to process.
⑦Here’s a golden rule: stay away from artificial sweeteners and look for non-sugar, natural sweeteners like Stevia or date sugar. In the war against artificial sweeteners and real sugar, both lose. Satisfy your sweet tooth with natural sugars that come from fruits and stay away from products claiming to be sugar-free or diet!

5 . A magazine did a survey in a community about different ways of life before and after the epidemic (疫情). 200 people were asked about food, health, online shopping and others in 2019 and 2023. Clearly, most people pay less attention to whether the food tastes delicious or not after the epidemic, but they prefer to choose healthier food. If possible, more people would like to cook dishes at home rather than eat out. As for shopping, online shopping will still be popular. But it will move away from big retailer (零售店) websites to social media (媒体) websites. That may be because surfing the Internet was a popular way for people to “kill time” during the epidemic. What people talk about most in 2023 is health. More and more people, both young and old spend more time taking care of their health.
The following chart is about the ways people choose to keep healthy. Taking exercise ranks (排名) first. However, many believe that taking exercise properly, is necessary. At the same time, healthy eating habits and mental health (心理健康) are important as well.

Many scientists believe our love of sugar may actually be an addiction (上瘾). When we eat or drink sugary foods, the sugar goes into our blood and influences the parts of our brain that make us feel good. Then the good feeling goes away, leaving us wanting more. All tasty foods do this, but sugar has an especially strong influence. In this way, it is an addictive drug (药) that doctors suggest we should all cut down on.
“It seems like every time I study an illness and follow a way to the cause, I find my way back to sugar,” says scientist Richard Johnson, One-third of adults worldwide have high blood pressure, and up to 347 million have diabetes (糖尿病). Why? “Sugar, we believe, is one of the causes, if not the major (主要) cause,” says Johnson.
Our bodies are designed to live on very little sugar. Early humans often had very little food, so our bodies learned to be very experienced in storing sugar as fat. In this way, we had energy stored for when there was no food. But today, most people have more than enough. So the very thing that once saved us may now be killing us.
So what is the solution? It’s clear that we need to eat less sugar. The trouble is, in today’s work, it’s not easy to avoid. From breakfast cereals (谷物) to after-dinner desserts (甜点), our foods are increasingly filled with it. Some producer even use sugar to replace taste in foods that are advertised as low in fat. So while the foods appear to be healthier, plenty of sugar are often added.
1. What did scientists find about sugar?| A．It can be found in all tasty foods. | B．It is something that influence our brain. |
| C．It can make us feel good for a long time. | D．It is the main cause of high blood pressure. |
| A．Saving sugar as fat. | B．Having less energy. |
| C．Having no food to eat. | D．Eating too much fat. |
| A．People today seldom exercise. | B．We get used to eat it at school. |
| C．It’s in so many food and drinks. | D．Some producers sell too much sugar. |
| A．To remind readers to eat less sugar. | B．To ask scientists to fight against sugar. |
| C．To tell readers the illness caused by sugar. | D．To teach readers different ways to store sugar. |
7 . ①Water plays an important role in keeping you healthy. It keeps your body work properly. But do you know that too much water can poison (使……中毒) you?
②Water poisoning happens when people drink too much water. This lowers the level of sodium (钠) in their blood to dangerous levels.
③You probably already know that high levels of sodium can be unhealthy. That’s true. But low levels are also harmful. When you have too little sodium in your body, your cells (细胞) begin to swell (膨胀). As a result, a lot of things will go seriously wrong in your body.
④Your brain may begin to swell. You may get a headache, feel very tired and want to throw up (呕吐). You may even lose consciousness (知觉). In these situations, water poisoning can make you dead.
⑤Protecting yourself from water poisoning may seem easy—just don’t drink too much water, right? In some situations, however, this is easier said than done. For example, when you do some heavy exercise, such as running 40 kilometers, you may have to drink a lot of water. Then, it is important to balance (平衡) the amount of water you drink with the amount of water your body is losing. This can help you stay healthy whenever you are exercising.
⑥So how much water should a person drink each day? In fact, the actual amount needed is different for each person. Today, most doctors are telling people that they should drink water whenever they feel thirsty.
⑦We can’t live without water. Neither can we live with too much water in our bodies. Make sure you take the right amount of it each day—staying healthy is all about staying balanced.

8 . By now, most people know they should eat more vegetables. But are there ways to get more from the vegetables you already eat? Research shows that when it comes to vegetables, it’s nọt only how much we eat, but also how we prepare them, which decides how many vitamins (维他命) and other nutrients (营养) enter our body.
Many studies show that people who eat lots of vegetables have fewer illnesses and eye problems. But raw (生的) vegetables are not always the best. The researchers found that 198 Germans who ate raw food were short of lycopene (番茄红素), which is found in tomatoes and other red vegetables. “There is an idea that raw foods are always going to be better,” says Steven K. Clinton, a professor at Ohio State University.
“For fruits and vegetables, sometimes a little bit of cooking can be helpful.” A number of factors decide how the vegetables do good to people’s health before they reach the table, including where and how they were grown and stored before being bought. No single cooking way is the best.
Some nutrients are easily lost in cooking if they are cooked in different ways. Vitamins C and B are often lost. In January, another report said that boiling was better for carrots than frying or serving them raw. Frying (炒) was the worst way to cook.
What cooked with the vegetables can also be important. When the vegetables were cooked with fat, the diners can get more nutrients. Fat can also make the taste of vegetables better, meaning that people will eat more of them. Putting on some other things can also make them taste better. For example, a little salt can make the food taste better.

Thanks to improvements in both health care and personal safety, most people are living healthier, longer lives.
