“What were they thinking?” Like most parents of teens, I ask myself this question on a regular basis in regard to the decisions my kids make. For the most part, their bad decisions include unhealthy food choices or watching Netflix instead of doing their homework. It’s usually not a big deal unless they start throwing up because they ate something that they knew would make them sick or they have rush around to turn in their schoolwork on time because they wasted six hours watching “Stranger Things”. But for many adolescents, their bad decisions have much more terrible consequences.
Scientists have been trying to unlock the secrets of the adolescent brain for years. Now new research shows that adolescent brains go through structural changes that may affect their ability to make sound decisions.
Changes in the adolescent brain at this stage of development are responsible for several unpredictable behaviors. For example, the adolescent brain’s hunger for the “feel good” chemical, dopamine, drives young people to push boundaries and take risks. These structural brain differences may also be responsible for the fact that teens and young adults tend to over-identify with others and focus heavily on every setback (挫折). Add to these factors such as social media and sleep problems and it’s no wonder that when adolescents are presented with important decision-making opportunities, normal social taboos (禁忌) disappear and negative actions arise.
With a better understanding of adolescent brains, researchers are learning ways to use social media to connect teens with others so they can find help quickly when they need it. There has also been a much bigger push in recent years to talk about mental health in school as part of health curriculum (课程表). Just as kids learn about the importance of taking care of their physical health, they can also begin to understand things that might be affecting their emotional well-being.
The adolescent years are important. The more we know about adolescent brains, the better equipped we will be to help guide them through those confusing years and the problems they may face.

Some people are productive and happy with fewer hours of sleep, while others need more. Still, experts can determine guidelines that work for most people. The National Sleep Foundation researched the topic and gave new recommendations this week. The foundation acknowledge s that sleep needs will very lifestyle and stress should be taken into consideration but their recommendations offer a general guideline. For example, teenagers (14-17 years old) need 8-10 hours’ sleep every day.
To create the recommendations, some sleep and medical experts reviewed 312 articles from journals published during the last decade. This is the first time that a professional organization has developed age -specific recommended sleep durations (时长)bbased on systematic review of the world scientific literature.
A lack of sleep can be linked to weight gain, because that causes an increase in appetite, according to the foundation. It can also have serious consequences on the brain. People who do not get enough sleep are at increased risk for depression (抑郁症), and can endanger others. Those who become sleepy while driving, for example, risk both their lives and the lives of those around them.
Researchers also have found in the past that too much sleep can have negative effects. Low socioeconomic status and depression reportedly are significantly associated with longer sleep. However, experts nowadays find that research on oversleeping is still doubtful and needs more attention. Currently, there is no strong evidence that sleeping too much has health consequences. There is, however, laboratory evidence that short sleep durations of four to five hours have negative consequences. We need similar laboratory studies to determine whether long sleep durations result in physiological changes that could lead to disease before we make any recommendations against sleep extension.

“It may prevent the correct understanding of the brain over the amount of food ingested,”said researchers who filmed 62 volunteers eating alone.
The men and women, aged 18 to 28, were invited to help themselves to a choice of food – ranging from healthy options to soft drinks and chocolate – until they were satisfied. In three trials, the volunteers were recorded eating with no distractions, using a smartphone or reading a magazine.
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. They also ate more when reading a magazine.
“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 smart phones have become the main ‘distracters”’during meals, even early in childhood, so it is important to pay attention to how this may impact food choices.”
“A distracter prevents the brain correctly understanding the amount of food ingested.” The study is published in the journal Physiology And Behavior.

【推荐3】Have you ever sat down in a restaurant and felt instantly drawn to a particular dish on the menu? The reason might be something as simple as that you love the dish’s main ingredient, but it’s often more than that.
Scientists are finding that the way food is presented can make a big difference. In one study, for example, party guests were given a glass of a drink called mango lassi. Half the guests were told the lassi was healthy. The rest were told it was unhealthy. Those who had the “healthy” drink considered it 55% less enjoyable than those who drank the “unhealthy” one, though the drinks were exactly the same.
People’s choices around what to eat are influenced by lots of small factors unconsciously. But we can make those choices more conscious by arming ourselves with information.
Agriculture accounts for about 25% of all greenhouse gas emissions warming the planet. But not all foods have equal influences. Globally, the production of animal-based foods accounts for about two-thirds of agricultural emissions, while plant-based foods generally have lower environmental influences.
Increasing the share of plant-based foods in our diets is therefore a key step in reducing agriculture’s pressure on climate. That doesn’t mean giving up meat, though. We can eat less animal-based food and more plants.
By examining how food decisions are made, scientists have learned that simple pushes can change people’s behavior in big ways. Restaurants, hotels, universities, and even cities have begun applying the latest behavioral science to help consumers cut their carbon footprint by choosing more sustainable foods. Burger King began a trial of the plant-based Impossible Burger. At Seattle Pacific University, campus food service provider Sodexo doubled the size of its plant-rich food station.

【推荐1】One devoted man is helping to make sure that children with poor living conditions won't go hungry during the school day.
Mary’s Meals, an organization founded in 2002 by Scottish farmer Magnus Macfarlane-Barrow, provides needy kids in 12 countries with free meals at school each weekday. The group's aim is to ensure that students have food in their stomachs so they can better fix their attention on the study in class.
Macfarlane-Barrow, who runs Mary’s Meals on his father's farm, told CNN that the entire operation started with a conversation he had with a teen living in a poor state. He said, ''In 2002, I was in Malawi during a year of terribly short of food, and I met this family — the father had died, and the mother was dying with her six children around her. I began talking to her oldest child, Edward, who was about 14, and asked him, 'What are your hopes? 'And he said, 'I'd like to have enough food to eat, and I'd like to go to school one day. ''' And that was it.
In its first year, the group fed 200 children in need. Since that time, it has made rapid progress. Last month, Mary's Meals fed more than one million children every school day. That was 5 million meals every week. ''The million is amazingly important, but we are far from satisfied. Our work's just beginning. We’ve proved that this works, and now we've just thinking about the next child, '' said Macfarlane-Barrow.
He and the group recently celebrated the achievement in Malawi, where the program began. So far, the program has had very good results. In Malawi, schools that carried out the Mary's Meals program saw a 24 percent increase in the number of new students within the first six months.

【推荐2】There are many useful things we can do each day to feel better. It may take some efforts and time to make a habit of drinking 8 glasses of water daily or thinking more positively, but it is well worth it. What things do you do every day to feel better?
Probably the healthiest thing you can do to feel better each day is to exercise early in the morning. You don't have to run the whole morning or spend a few hours in the gym. Even doing some easy exercise like walking, sit-ups or jumping the rope will help you feel better in no time!
Again, due to our busy schedules, we don't get enough sleep each night. If you have trouble falling asleep, avoid watching TV or surfing the Internet right before bed. Also, try to make healthy bedtime snack choices and don't drink tea or coffee too late in the day.
If you drink 3 glasses of water, 4 glasses of coffee or tea and a glass of soda each day and think that you drink enough water, think again. Your body needs water (not coffee or soda!) to function properly. Aiming to drink 7-8 glasses of water each day can make you feel better.
Being positive is the key to a longer life. Positive thoughts can help improve your overall heath. Life is full of stressful situations and it's hard to stay cheerful when everything goes wrong, but your positive attitude can help you solve any problem and fight any stress faster and easier. Your positive attitude is especially good for your heart health. Smile, stay positive and live a longer life!
