In addition to a list of benefits for a healthy gut, yogurt may greatly reduce your risk of heart disease and stroke. A recent study in the American Journal of Hypertension found that men who eat at least two servings of yogurt per week had a 21 percent lower risk of developing cardiovascular disease, and risk among women dropped by 17%.

A team of scientists at Boston University's School of Medicine studied more than 740,000 individuals who had previously suffered from high blood pressure. Using health questionnaires administered over the last 30 years, the scientists measured yogurt intake and weighed it against heart-related health problems such as heart attack or stroke.

In a press release, one of the study's authors showed that the team behind the report had initially wanted to see if fermented dairy products could aid poor cardiovascular health. The study shows a relationship between yogurt and heart health—but it's not yet clear whether eating yogurt actually reduces risk, or that overall healthier people tend to eat more yogurt, so more research will have to be done.

Still, recent studies have found health benefits of a variety of probiotic and dairy foods, including the super-food kefir which significantly boosts gut health. And recent scientific research has found heart-healthy benefits from eating small amounts of cheese every day.

While the researchers didn't target a particular variety of yogurt, it's important to recognize that yogurt brands greatly vary in the dairy aisle, and some are better for you than others. It's clear that yogurt can be a great addition to your diet due to probiotics, calcium levels, and a healthy source of fat.

Regardless of which kind you choose to pick up, this new evidence could finally be the final bit of buzz to get you to include yogurt as your daily diet. Added bonus? There's a way you can try a lot of different yogurts for free this month, too.

文章大意:这是一篇说明文。本文主要介绍了吃苹果对健康的益处及为什么会有这些益处。

【推荐1】Apples have always played a significant yet diverse role in history. Today apples continue to astonish in medicine, with headlines reporting that an apple a day really does have health benefits. In 2013, researchers in Oxford suggested that either an apple a day or a statin (a kind of drug) seemed to be equally successful at preventing heart attacks and strokes in people over the age of 50.

EPIC study, one of the biggest studies of its kind, involves half a million people and looks at the effects of eating fruit and vegetables on disease. Participants consuming at least eight portions a day had an astonishing 22% lower risk of heart disease, and risks of some cancers were slightly reduced. However, other cancers were unaffected, and there was no real effect on diabetes.

How might the humble apple be declaring war on heart disease and cancer, two of our biggest killers? The answer might lie in polyphenols (多酚) in apples, which is useful for protecting the fruit from disease and also giving it color and flavor. They have the potential to protect our body by reducing blood stickiness and cholesterol (胆固醇) levels.

Several studies also show a reduction in blood pressure when more fruit and vegetables are eaten. Furthermore, apples contain a fibre called pectin (果胶) which sticks to cholesterol in the body, slowing their absorption. What is clear is that the apple is a complex mix of components, working together for the good of our health.

But can we eat enough apples a day to keep the doctor away? Eating too many may not be a good idea, especially with a risk of lasting exposure to low levels of pesticide. Some people are even allergic to apples, and they can wear away outer layer of tooth. The Department of Health’s advice to consume “5-a-day” (including both fruit and vegetables) might be a realistic starting point.

1. Which of the following do the researchers agree with?
A.An apple a day can successfully cure heart diseases.
B.Eating fruit and vegetables can reduce diabetes greatly.
C.Apples and medicine have similar effect in some cases.
D.Those eating apples have a lower risk of all cancers.
2. Why are polyphenols and pectin mentioned in the text?
A.To make a comparison.B.To give advice on health.
C.To tell what apples contain.D.To clarify how apples work.
3. What does the underlined phrase “5-a-day” in the last paragraph refer to?
A.An apple and five vegetables per day.B.Five apples in different times every day.
C.Two apples and three vegetables every day.D.Five portions of fruit and vegetables per day.
4. Where is the text probably taken from?
A.A biology textbook.B.A health magazine.
C.A travel brochure.D.A nursing report.

文章大意:本文是一篇说明文。最近,一些美国科学家向工业化国家的人们提出了一条有用而真诚的建议:如果他们多吃一万多年前人类所吃的同类食物,他们会更健康。石器时代的人比今天的人健康得多,因为他们吃了很多野生动物,新鲜的野生蔬菜和水果。

【推荐2】Recently some American scientists have given a useful sincere piece of advice to people in industrialized nations that they would be much healthier if they ate more of the same kind of food eaten by humans living more than 10,000 years ago.

The scientists say that the human body has changed very little since humans first appeared on the earth, but the way we live has changed greatly. Our body has not been able to deal with these changes in life style and this has led to new kinds of sicknesses. These new sicknesses were not known in ancient times, so they are called “diseases of civilization”. Many cancers and diseases of the blood system, including heart attacks and strokes (中风) are examples of such diseases.

Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol (酒精) or tobacco (烟草), probably none. Ancient people also got a great deal of physical exercise, but a change in food is one of the main differences between life in ancient times and that of today.

Stone-age people hunted wild animals for their meat, which had much less fat than domestic or tame ones (家畜). They also ate a lot of fresh wild vegetables and fruits. They didn’t have milk or any other dairy products, and they made very little use of grains. But today, we eat a large amount of these. We eat six times more salt than our remote ancestors (祖先). We eat more sugar. We eat twice as much fat but only one third as much protein (蛋白质) and much less vitamin C.

People today probably do not want to live the way people thousands of years ago did, but scientists say that we would be much healthier if we ate much the same way as remote ancestors did, cutting the amount of fatty, salty and sweet food.

1. According to the passage, people in industrialized nations would be much healthier if they ate___________.
A.more food than humans living 10,000 years ago did.
B.as much food as humans living 10,000 years ago did
C.more kinds of food eaten by people living over 10,000 years ago.
D.more of the same kind of food eaten by people over 10,000 years ago.
2. New kinds of sicknesses have been found because __________.
A.the human body has changed compared with humans who first appeared on the earth.
B.the way we live has changed a little.
C.our body can’t deal with the changes in life style.
D.the way we live today is proper for the human body.
3. What is the main cause that people suffer from a lot of new sicknesses?
A.Ancient people did a great deal of physical exercise.
B.People today have a lot of alcohol.
C.People today have more tobacco.
D.Food today is quite different from that of ancient times.
4. According to some scientists , Stone-age people were much healthier than people today because they ate a lot of _____________.
A.milk and other dairy products.B.wild animals, fresh wild vegetables and fruits.
C.salt and sugarD.grain foods

【推荐3】How Smartphone Adds to Your Weight

Using a smartphone at mealtimes can lead to an expanding waistline. Researchers have found that men and women consumed 15% more calories when looking at their phones while eating.     1     The groundbreaking study suggests that staring at a phone screen may distract (分心) dinners from how much food and what they are actually eating.

“It may prevent the correct understanding of the brain over the amount of food ingested,” said researchers who filmed 62 volunteers eating alone.

The volunteers, aged 18 to 28, were divided in to three groups and invited to help themselves to a choice of food — ranging from healthy options to soft drinks and chocolate — until they were satisfied.     2     On average, the volunteers ate 535 calories without the distraction of a smartphone but 591 when using a mobile. Those in the sample who were classed as overweight ate 616 calories while using their phones. When in possession of their mobiles, the volunteers also consumed 10 percent more fatty foods.     3    

“Smartphone use during a meal increased calorie and fat intake,” said Márcio Gilberto Zangeronimoa, a lead author of the study — carried out at the Federal University of Lavras in Brazil and University Medical Center Utrecht in the Netherlands. He added: “Tablets and smartphones have become the main ‘distracters’ during meals, even early in childhood.     4    A distracter prevents the brain correctly understanding the amount of food accepted.”    5     A more detailed analysis can be found in the journal.

A.They also eat more fatty food.
B.They also ate more when reading a magazine.
C.Distracted or hurried eating can add to weight gain.
D.The study is published in Physiology And Behavior.
E.It is important to pay attention to how this may impact food intakes.
F.Hunger isn’t the only thing that influences how much we eat during the day.
G.They were recorded eating with no distractions, using a smartphone or reading a magazine.
