1 . Use food to ease your moods? The time of meals may have an impact on moods, including levels of depression and anxiety, according to researchers at Brigham and Women’s Hospital.

To conduct the study, 19 participants (12 men and 7 women) were arranged to experience a Forced Process in a dark room for four 28-hour “days”. Participants were assigned to one of two meal timing groups: the Daytime and Nighttime Meal Control Group, which had meals according to a 28-hour cycle (resulting in eating both during the night and day, which is typical among night workers), and the Daytime Only Meal Group, which had meals on a 24-hour cycle (resulting in eating only during the day). The team then assessed depression and anxiety like mood levels every hour.

The result showed that meal timing significantly affected the participants’ mood levels. During the simulated (模拟的) night shift (day 4), those in the Daytime and Nighttime Meal Control Group had increased depression and anxiety like mood levels, compared to the baseline(day 1). In contrast, there were no changes in mood in the Daytime Only Meal Group. Participants with a greater degree of circadian(昼夜节律的) disorder experienced more depression and anxiety like moods.

Researchers discovered that among individuals in the daytime and nighttime eating groups, anxiety and depression rose by 16% and 26% individually. A famous author Sarah Chellappa, who completed work on this project, said, “Meal timing is emerging as an important aspect of nutrition that may influence physical health, but the causal role of the timing of food intake in affecting mental health remains to be tested. Future studies are required to establish if changes in meal timing can lead individuals to experience anxiety-related disorders.”

The findings open the door for studying a behavioral strategy that might benefit individuals suffering from mental health disorders, such as shift workers. The study also adds to a growing body of evidence finding that strategies that improve sleep and circadian patterns may help promote mental health.

3 . Obesity (肥胖) has become a serious problem now. According to a recent survey, teenage obesity has increased at an alarming rate across America. Teenage obesity is mainly due to the increased consumption (消耗) of junk food which contains large amounts of fat. This has exposed the teens to a 14% greater risk of having a heart attack as well as seriously high blood pressure.

Various causes of teen obesity have been claimed, the most important of which is being insufficient (不足) physical exercise on the teen’s part. It is argued that teens nowadays who lack (缺少) sufficient physical exercise topped with their unhealthy eating habits are more likely to be obese. Nowadays, a main part of the teenagers spend their spare time on the computer, television or perhaps simply playing games. This greatly limits any kind of physical activity of the teenager. According to a recent survey, around 43% of teenagers spend more than 2 hours watching television every single day.

Long time inactivity in addition to the ill eating habits has increased the incidence (发生率) of obesity in teenagers even more, However, this does not mean that teens do not do enough exercise, but the amount which they do, is certainly not sufficient as compared to their intake of fatty foods. Besides this, parents need to change the whole lifestyle of the family in order to develop a healthier lifestyle of their children.

The teenagers must also be encouraged to take part in other physical activities which require more effort; such as playing basketball, tennis, badminton, volleyball and swimming. Meanwhile, the teenagers also need to be educated on the ill effects of junk food and must be asked to avoid them as much as possible. Their diet must also be made healthier and more balanced, which will help them in losing more weight quickly. For better guidance on reducing the teen’s weight quickly, parents can always turn to a doctor.

4 . The old saying that “laughter is the best medicine” may contain an element of truth when it comes to heart health. A research has demonstrated that laughing causes the tissue inside the heart to expand and increases oxygen flow around the body.

“Our study found that laughter treatment increased the functional capacity of the cardiovascular (心血管的) system, and patients with heart disease who engaged in a course of laughter treatment had reduced inflammation (炎症) and better health.” said the lead author, Prof Marco Safffi, of the Hospital de Clinicas de Porto Alegre in Brazil.

In the trial, scientists carried out a first-of-its-kind study to examine if laughter treatment could improve symptoms of patients with heart disease. It involved 26 adults with an average age of 64, all diagnosed with the heart disease caused by plaque (斑块) buildup in the walls of the arteries (动脉) that supply blood to the heart. Over three months, half were asked to watch two different hour-long comedy programmes each week, including funny popular sitcoms. The other half watched two different serious documentaries, about heavy topics such as politics or the Amazon rainforest.

At the end of the 12-week study period, the comedy group improved by 10% in a test measuring how much oxygen their heart could pump around the body. The group also improved in a second measure that tested how well arteries can expand. They also had a blood test to measure several inflammatory markers, which indicate how much plaque has built up in the blood vessels and whether people are at risk of heart attack or stroke. The results showed that their inflammatory markers had significantly reduced compared with the documentary group.

“When patients with heart disease arrive at hospital, they usually have a lot of inflammatory markers.” said Saffi. “It’s really good news that laughter treatment is a good intervention that could help reduce inflammation and decrease the risk of heart attack and stroke.”

5 . Spending time outdoors has long been linked (联系) to better health. Gardening goes beyond just beautifying outdoor spaces—it can have a deep effect on our physical and mental (身心上的) health.

Gardening involves physical activity that works all the main muscle (肌肉) groups, which is helpful for overall health. “Activities such as digging, planting, weeding and harvesting require movement and can help to improve strength,” said Clayton, CEO of an online lawn care company. “Performing these activities regularly can help burn calories, and keep a healthy weight.”

Beyond burning calories and building muscle, lots of studies have shown that gardening can improve the immune system (免疫系统). The Centers for Disease Control and Prevention (CDC) recommends that people get at least 150 minutes of exercise each week, and gardening is listed as a suitable activity. Doing garden work for that time each week can reduce the risk of obesity, high blood pressure and heart disease. Additionally, spending time outdoors makes us get close to natural sunlight, which is important for vitamin D synth.

Gardening provides a chance for social connection, too. It can be a shared activity among family members, friends or neighbors, building relationships and a sense of belonging.

Gardening also offers cognitive (认知的) benefits. It excites the senses, improves focus and encourages problem-solving and creativity. It provides a chance to learn about plants, ecosystems and the environment, developing a deeper understanding and appreciation for nature.

6 . 阅读下面材料，在空白处填入适当的内容(1个单词)或括号内单词的正确形式。

Eating ultraprocessed foods (超加工食品) for more than 20% of your daily calorie intake every day could lead to cognitive decline, a new study revealed. Studies have found these foods can raise our risk     1     obesity, heart problems, diabetes and cancer. They may even     2     (short) our lives.

The key problem with ultraprocessed foods is that they are usually very high in sugar, salt and fat, all of     3     promote systemic inflammation (炎症). Ultraprocessed foods     4     (define) as industrial formulations of ingredients. They contain little or no whole foods and     5     (typical) include flavorings, colorings and other     6     (chemistry) substance, according to the study. Those in the study who ate the most ultraprocessed foods were more likely to be younger, women, white, had higher     7     (educate) and income, and were less likely     8     (be) current alcohol consumers, the study found. “People need to know they should cook more and prepare     9     (they) own food from scratch,” a researcher said. “And it’s worth it because you’re going to protect your heart and guard your brain from Alzheimer’s disease,” she added. “That’s the take-home message: Stop     10     (buy) things that are superprocessed.”

7 . Soda and sports drinks are the largest single source of added sugars for Americans. They add an average of 145 calories a day to our diets. Most efforts to reduce drinking focus on soda. That is not enough, Juice is as bad.

Americans drink a lot of juice. The average adult drinks 6.6 gallons per year. More than half of preschool-age children drink juice every day. These children drink about 10 ounces every day. That is more than twice the amount that is good for them. Fruit juice contains some nutrients (营养物). But it has tons of sugar. One 12-ounce glass of orange juice contains ten teaspoons of sugar. That is about what is in a can of Coke.

The government is not right when it says up to half of daily fruit servings can be served in the form of 100 percent juice. One-hundred-percent fruit juice is not a natural source of vitamins and calcium. The government also recommends drinking fortified (增加营养的) orange juice. This is to get vitamin D. Some brands of juice are even marketed to babies. So what parents should do is read the label and be more careful.

Government food programs for kids are also at fault. Children in these programs drink more fruit juice than they should.

Drinking fruit juice is not the same as eating the whole fruit. Fruits like apples and grapes reduce the risk of diabetes (糖尿病). Drinking fruit juice is the opposite. Juice has more concentrated sugar and calories. It also has less fiber. Juice is easy to drink. It is harder to eat the whole fruit.

No expert says that juice improves health. It is like other sugary drinks. You can drink it one once in a while. But it is not because your body needs it. Parents should serve their kids water. They should serve the whole fruit. Schools and day care centers should stop serving juice. Government guidelines should not say that fruit juice is like the whole fruit.
