Teenagers who spend hours in front of the television may have a poorer diet as young adults.
A study, which included nearly 1,400 high school students, found those who watched TV for five hours or more per day had less healthy diets than peers(同龄人) five years later. Why does this happen? Should the parents take any measures?
On the one hand, people who spend a lot of time in front of the TV, especially teenagers, may snack more, and that may affect their long-term diet quality.
On the other hand, TV ads for fast food, sweets and snacks tempt teenagers to eat more of those foods. And TV time might also replace exercise time for some kids.
Lead researcher Dr. Daheia of the University of Minnesota in Minneapolis, told Reuters Health a clear correlation(关联) between TV time during high school and diet quality in young adulthood. While the heaviest TV viewers were eating the most junk food, those who’d watched less than two hours per day had the highest intake(吸收) of fruits, vegetables, whole grains and high-calcium food. In her opinion, parents should limit and monitor TV viewing.
As far as I am concerned, children should watch no more than two hours of television per day. And parents should set a good example by eating right, being physically active and curbing their own TV time.

【推荐2】The Healthy Habits Survey shows that only about one third of American seniors have correct habits. Here are some findings and expert advice.
1. How many times did you brush your teeth yesterday?
Finding: A full 33% of seniors brush their teeth only once a day.
Step: Remove the 300 types of bacteria in your mouth each morning with a battery-operated toothbrush. Brush gently for 2 minutes, at least twice a day.
2. How many times did you wash your hands or bathe yesterday?
Finding: Seniors, on average, bathe fewer than 3 days a week. And nearly 30% wash their hands only 4 times a day—half of the number doctors recommend.
Step: We touch our faces around 3,000 times a day—often inviting germs(病菌)to enter our mouth, nose, and eyes. Use toilet paper to avoid touching the door handle. And, most important, wash your hands often with running water and soap for 20 seconds.
3. How often do you think about fighting germs?
Finding: Seniors are not fighting germs as well as they should.
Step: Be aware of germs. Do you know it is not your toilet but your kitchen sponge (海绵)that can carry more germs than anything else? To kill these germs, keep your sponge in the microwave for 10 seconds.

Later that day I was told by the hospital what I did helped rescue the old man's life. I was happy to hear that.

What Emily didn't know at the time was that she was suffering from an illness called binge-eating disorder(BED)(暴饮暴食).
For years, Emily didn't tell anyone what she was doing. She felt ashamed, alone, and out of control. Why don't famous people confess (承认) to BED, as they do to anorexia? It's simple: There's a stigma(污名)involved. “Overeating is seen as very bad, but dieting to be skinny is seen as positive and even associated with determination," says Charles Sophy, a doctor in Beverly Hills , California.
"Some parents or friends may look at a teen with BED and think, 'Oh, a good diet and some will-power will do the trick.' But that's not true," says Dr.Ovidio Bermudez , a baby doctor at the Eating Recovery Center in Denver. "Eating disorders are real physical and mental health issues; it's not about willpower." The focus in treating BED shouldn't be on weight, because as with all eating disorders, the behaviors with food are a symptom of something deeper.
Like most other diseases, genetics may play a big part in who gets BED and who doesn't. If you have a close relative with an eating disorder, that means you're more likely to develop an eating disorder of your own.
Besides, many people with BED have tried at some point or another to control it by going on a diet, but paying more attention to food doesn't help. And it might even make things worse, like it did for Carla, who's 15 now and is recovering from BED. "My parents would always tease me about my weight, so when I was 14, I went on a very restrictive diet," she says. When you can't have something, you only want it more, so every time Carla would have a bite of something that wasn't allowed on her strict diet. She would quickly lose control and binge (狂欢).

【推荐3】From the moment we’re born, we acquire, and develop an internal ecosystem of microbes (微生物), trillions of them in all, which are living together with us in our body. In fact, there are roughly as many microbial cells in our bodies as human cells. This prosperous microbial world is called our microbiome.
While some microbes can make us ill, we need our microbiome to survive. Combined, they are every bit as essential as our heart, our lungs or our brain. We have microbes living all over our skin and in every other parts of our bodies. But most of the microbiome is found in our guts (肠道). Our gut microbes are essential for digestion. They also help regulate hormones and they can improve our immune system (免疫系统).
Our microbiome contains a wide range of microbes, some of which have beneficial effects on our health and some of which are detrimental. A healthy collection of microbes seems to be vital for our wellbeing, protecting against some of the biggest health threats, like heart disease, obesity, diabetes, arthritis and even depression.
On the other hand, having an unhealthy microbiome may be a contributing factor for many common diseases. Our modern lifestyles, western diets and overuse of antibiotics might all be having a harmful effect on our internal ecology.
So how do you develop a healthy microbiome? Well, it seems that the more diverse your microbial population is, the better. And the best way to increase your diversity is to eat a wide range of plant- based foods. Research shows that people who have at least 30 plant- based elements in their diet every week have a wider range of microbes in their gut, and that’s linked to better weight management, better heart health and better mental health.
