1 . With low or no-carbohydrate diets rising in popularity in recent times, the potato is now regularly overlooked in favour of other vegetables. In fact, research literature has previously indicated potatoes may have a detrimental effect on health, such as increasing the possibility of developing Type2 diabetes(糖尿病).

However, new research done by Edith Cowan University (ECU) has shown while potatoes may not have all the same benefits as some other vegetables, such as lowering risk of Type 2 diabetes, health issues associated with potatoes may actually be due to how people are preparing them and what they’re eating them with.

A recent analysis of this study led by Dr Nicola Bondonno from ECU’s Nutrition and Health Innovation Research Institute found people who consumed the most vegetables were 21 percent less likely to develop Type 2 diabetes than those who consumed the least amount of vegetables. PhD candidate Pratik Pokharel carried out work on the analysis and said while potatoes didn’t have the same impact on Type 2 diabetes, they also didn’t have any negative effect.

“In Denmark, people consume potatoes prepared in many different ways. In our study, we could distinguish between the different preparation methods. When we separated boiled potatoes from mashed potatoes(土豆泥), fries or crisps, boiled potatoes were no longer associated with a higher risk of diabetes: They had a zero effect,” said Pokharel.

“In our study, people who ate the most potatoes also consumed more butter, red meat and soft drinks-foods known to increase your risk of Type 2 diabetes,” said Pokharel. “We should separate potatoes from other vegetables in regard to messaging about disease prevention but replacing refined grains such as white rice and pasta(意大利面食)with potatoes can improve your diet quality because of fibre and other nutrients found in potatoes.”

3 . A study came out just a few days ago that found people who eat healthily about 80 percent of the time have a high protection on brain health.     1    

It doesn’t mean that you should just go to crazy 80% of the time. But be more aware that you are more likely to stick to a healthy lifestyle if there’s some relaxation here and there. That’s all part of living.

My name is Mark Mailstein and I’m a brain health researcher and the author of The Age-proof Brain.

    2    

For breakfast, I try to eat oatmeal(麦片粥).Usually it’s the quick, the instant, but make sure that it’s not the type with any added sugar.     3    

And then lunch and dinner. I pretty much try to keep really simple. I will look at my plate and have some sort of lean meat. I eat a lot of fish and chicken. And I really just try to think of mixed vegetables, like really colorful plates of fruits, vegetables you know.     4     There are these interesting studies that show it’s the combinations of different types of vegetables, so I try to mix them in.

Sometimes I think something that might be surprising is that I might have a smoothie(奶昔) for dinner as a way to get all those vegetables in. My go-to smoothie is that I take broccoli (西兰花).     5    And I throw carrots and all sorts of vegetables in there.

A．I really like sweet potatoes.

Hospital Food — The Best Medicine

Few sick people consider the quality of the food when choosing a hospital. That is perhaps just as well. Even in America, a country where private hospitals have long provided individual rooms with such comforts as personal cable television, patients are often still fed institutional food “Mystery meat” and     1     (process) cheese slices are common.     2     gets cooked in a microwave. Many of country’s biggest hospitals get their food from the likes of Ara-mark, a giant global caterer that also provides meals to schools and prisons.

More hospitals are starting to feed their patients better food. Inter-mountain, a nonprofit group based in Utah that runs 32 hospitals across the Mountain West, has since 2019 served freshly made meals to patients. Chefs in proper kitchens now source local ingredients to serve in cafeterias. Doctors are consulted to meet patients’ dietary needs. Christopher Delissio, the head chef at Inter-mountain, describes     3     (create) a meal for a Mexican child who was being treated for cancer. “He     4     not eat, mumbling the food was tasteless,” Mr Delissio recalls, and that was making it harder for him to recover from chemotherapy. “I was able to go up on the floor, speak to this boy’s parents and him and kind of     5     (figure) out what he wanted,” he says.

The link between eating well and good health has long been clear, says David Eisenberg, a nutrition specialist at the Harvard School of Public Health. Heart disease, which has a direct connection to diet, is America’s     6     (big) killer. Roughly two-fifths of American adults are clinically obese, and over 14% suffer from diabetes. The right food can help patients avoid going back to hospital. Yet doctors     7     have often been slow to re-cognise the need to encourage healthy eating, says Dr Eisenberg. Most health care remains curative,     8     preventive. Medical schools still rarely teach much about nutrition.

A decade ago Henry Ford Hospital in West Bloomfield, outside Detroit, opened a teaching kitchen     9     staff could help patients plan affordable, healthy meals and learn how to cook them. The idea is now spreading widely. In October a conference for health and food professionals in Los Angeles will encourage the adoption of such kitchens. Participants will tour a new one that has just opened at UCLA’s hospital.

Challenges remain. Doctors do not get paid more     10    , owing to healthier eating, patients no longer need treatment. But at least, says Dr Eisenberg, insurers are starting to balk at the expense associated with chronically sick patients.

7 . Can energy drinks really make you energetic? A survey, by Cancer Council Australia among more than 9000 students across the country, found teenagers who were bitten by the energy drinks bug and drank energy drinks at least once a day were twice as likely to get less than eight hours’ sleep on school night than those who didn’t.

The same survey found one in six teenagers take in at least 5.2kg of sugar each year from sugary drinks alone. “This can lead to weight gain and obesity, increasing the risk of heart and kidney disease, type2 diabetes, stroke and some cancers,” Mr Sinclair said, who led the survey. Craig Sinclair, head of Rethink Sugary Drink, said the levels of sugar in energy drinks are very high, causing teenagers to put on weight.

The survey also found the caffeine (咖啡因) levels of the drinks is also high and this could explain the survey results on their effect on teenage sleep. Energy drinks contain 160mg of caffeine, more than twice as much as a cup of coffee or a 500ml bottle of cola, Mr Sinclair said. The Sleep Health Foundation says teenagers need 8-10 hours of sleep, more than an adult, because their bodies and cognition are growing rapidly. Sleep is important for teen mental health and the US Sleep Foundation says shortage of sleep can contribute to acne, bad behaviour and unhealthy eating habits. Associate Professor Matthew Hopcraft from the Australian Dental Association Victoria said energy drinks are also a major contributing factor to tooth decay and tooth erosion.

Royal Prince Alfred Hospital heart doctor Professor Chris Semsarian has tested the effects of energy drinks on the heart and said they can lead to an increased heart rate and irregular heart beat. “Caffeine is not the only stimulant (兴奋剂) part of these drinks, most also have guarana which is also a stimulant,” he said. Energy drinks have been related to scores of deaths around the world because of their high caffeine content.

1. What does the underlined phrase “bitten by the energy drink bug”?

A．Tired of energy drinks.	B．Equipped with energy drinks.
C．Fascinated by energy drinks.	D．Attacked by an insect in energy drinks.

2. According to the survey, what caused teenagers fond of drinking energy drinks not to sleep enough?

A．The high levels of caffeine.	B．The high levels of sugar.
C．The high levels of alcohol.	D．The shortage of exercise.

3. What effects do energy drinks have on the heart, according to Professor Chris Semsarian?

A．They can bring about decreased heart rate.

B．They can result in blood pressure rising.

C．They can lead to heart stopping working.

D．They can contribute to heart beating irregularly.

8 . Many people who want to lose weight often choose to go on a diet. But is this really the best way? With celebrities (名人) speaking about new diets that have helped them become slim (苗条的) in advertisements (广告), more and more people are turning to dieting. Some shops begin to sell diet products such as diet milkshakes, snack bars and even diet pills. However, such popular products and diets are often found to be extremely unhealthy.

Most of these popular diets work by cutting down on a certain nutrient (营养素) from your food intake (摄入量). For example, some diets work by cutting down on carbohydrates (碳水化合物). This means the body must use its fat reserves for energy. This might help you lose weight. However, by cutting a particular food group out of your diet, you are starving your body of a nutrient that it needs, which could leave you feeling weak, tired or even bad-tempered. Besides, these diets are often unsuccessful in the long run.

Generally, one of the most effective ways of losing weight is to cut down on calories. The recommended (推荐的) calorie intake for an adult male is 2,500. If a man consumes more than 2,500 calories each day, then he is likely to gain weight. However, if he consumes less, then he is likely to lose weight.

In fact, proteins, carbohydrates, fats, vitamins and minerals all play an important role in staying healthy, which is why they all should be included in your meals. Of course, some foods can be eaten in moderation (节制) as an occasional snack. For example, a bar of chocolate every once in a while won't cause you any problems.

So, instead of spending money on popular diet pills or special weight loss foods, try to eat healthy balanced meals containing foods from all food groups. So, next time your friends tell you that they are going on a diet, tell them that eating a healthy balanced diet is a much better choice.

1. What is the author's opinion about the popular diets mentioned in the passage?

A．They are useful for losing weight.

B．They are welcomed by celebrities.

C．They are not as healthy as people think.

D．They are replacing people's everyday meals.

2. What is the author's attitude towards the popular diet pills?

A．Curious.	B．Unfavorable.
C．Unconcerned.	D．Supportive.

3. How can we lose weight effectively according to the author?

A．By having diet pills.	B．By following a strict diet.
C．By taking regular exercise.	D．By reducing calorie intake.

4. What can we infer from the last paragraph?

A．Diet products should be limited.

B．Snacking is a big no-no for health.

C．Keeping a diet with various nutrients is ideal.

D．Going on a diet should be stopped immediately.
