To Track What You Eat and Drink

Keeping a food diary helps give you an accurate picture of what you eat every day.1. Here are some suggestions to track what you eat and drink.

Set up your diary. The simplest way to track what you eat and drink is by setting up your diary in a notebook or downloading a food journal app on your phone. You'll need to be able to keep track of the date, time, place, item eaten, quantity consumed, and extra notes.

2.The most accurate food journal will most likely be the most helpful as well. Try to jot down or take note of everything that goes into your mouth. Include all meals, drinks, snacks and even nibbles of food you eat while you cook.

Write down accurate quantities. If you're concerned about how many calories you consume, writing down the quantities you eat is important data to include in your diary.3.

4. Whether you're keeping a food diary to help you lose weight or you're trying to pinpoint a potential food allergy, your mood matters. Jot down notes on how a food or meal makes you feel. 5. For example, you might feel anxious and have an upset stomach after eating dairy-based foods.

A.Record all beverages.

B.Record everything you eat and drink.

C.Record how you feel after eating each item.

D.It also helps you manage or lose weight or help you eat healthier.

E.Don’t forget to include any physical symptoms or side effects after eating.

F.You might want to buy measuring cups to help ensure your quantities are correct.

G.Start taking down a few notes about your diet and you may be surprised at what you learn.

    You’re walking around and a thought occurs: “I should check my phone.” The phone comes out of your pocket. You type a message. Then your eyes remain glued to the screen, even when you walk across the street. We all do this kind of distracted walking, or“twalking.”

Why are we so addicted to it? People are, by nature, information-seeking creatures. When we regularly check our phones, we are snacking on information from devices that offer an all-you-can-eat buffet of information. And in some ways, smartphones were designed to be irresistible to information-seeking creatures.

However, at what point is this considered addiction?

Not all constant phone use was considered addictive, said Steven Sussman, a professor at the University of Southern California. External pressures, like a demanding job, could force people to frequently check their phones. But when people check their devices just to enhance their mood, this could be a sign of a developing problem.

Another signal of addictive behavior is becoming preoccupied with smartphone use when you should be doing something else. An even clearer indicator is what happens when the phone is taken away.

“Let’s say you go out to the mountains and you don’t get reception, so you can’t use a smartphone,” Dr. Sussman said. “Do you feel a sense of relief? Or do you feel, wow, I want to get out of these mountains — I want to use the smartphone. If you feel the latter, that’s toward the addictive direction.”

Jim Steyer, the chief executive of Common Sense Media, said there needed to be a broad public awareness campaign over the dangers of walking and texting in parallel with distracted driving.“You have distracted pedestrians and distracted drivers, so it’s the double whammy,” he said. “Tech addiction hits in both ways.”

1.What is probably the proper explanation of the word “twalking”?

A.Talk while working.

B.Text while walking.

C.Travel while walking.

D.Tease others while walking.

2.Why do we get into the habit of twalking ?

A.Twaling is interesting and beneficial.

B.The news on the cellphone is of great value.

C.Twalking is trend that everyone want to follow.

D.Smartphones comply with our eagerness for information.

3.Which of the following is regarded as addition?

A.We use smartphones constantly for work.

B.When we use the smartphones, we are in a bad mood.

C.When smartphones are taken away, we are anxious to find them.

D.Climbing mountains without cellphone makes us feel a sense of relief.

4.What can be reflected from Jim Stever’s words?

A.Distracted driving is more dangerous than twalking.

B.Twalking brings more dangers than distracted driving.

C.The number of twalking people is equal to distracted drivers.

D.Twalking and distracted driving deserve more public concern.

    Scientists have long known a fairly reliable way to extend life span in rodents(啮齿类动物) and other lab animals: Reduce the amount of calories they eat by 10 percent to 40 percent.

This strategy known as caloric restriction, has been shown to increase the life span of various organisms and reduce their rate of cancer and other age-related ailments. Whether it can do the same in people has been an open question. But an intriguing new study suggests that in young and middle-aged adults, chronically(慢性地) restricting calorie intake can have an impact on their health.

In the new study, researchers looked at a group of 143 healthy men and women who were instructed to practice caloric restriction for two years, with the aim of cutting the calories they consumed by 25 percent.

On average, the dieters managed to slash about 12 percent of their total calories, or roughly 300 calories a day, the amount in a few chocolate chip cookies or a small Starbucks Mocha. But the group saw many of their health markers improve.

They lost weight and body fat. Their blood pressure fell slightly, and they had better blood sugar control and less inflammation. At the same time, a control group of 75 healthy people who did not practice caloric restriction saw no improvements in any of these markers. Some of the benefits in the calorie restricted group stemmed from the fact that they lost a large amount of weight. However, the results of the survey suggest that caloric restriction might have some unique biological effects on disease pathways in the body.

Calorie restriction may be a useful tool for better health and weight loss, but it’s unclear whether the changes in the new study will ultimately translate into longevity and reductions in chronic disease, said Frank Hu, the chairman of the nutrition department at the Harvard, who was not involved in the research.

1.What happened to the lab animals, after the amount of calories was reduced?

A.More lab animals got cancers.

B.More Lab animals can live longer.

C.Health condition of lab animals got worse.

D.Lab animals will suffer from no disease in their future life.

2.From the study, after caloric restriction, what happened to the 143 people?

A.Their healthy markers improved.

B.They did not get chronic diseases.

C.They did not get lose any weight at all.

D.They did not eat chocolate chip cookies.

3.Which work has the similar meaning to the underline word, slash?

A.Reduce. B.Increase.

C.Add. D.Beat.

4.From Frank Hu’s words, what can be inferred?

A.Calorie restriction is beneficial to weight loss.

B.People with caloric restriction will love longer than others.

C.More people should be encouraged to take caloric restriction in life.

D.The relation between caloric restriction and longer lifespan is uncertain.
