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.
“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.
“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.

【推荐1】Do you know that nearly every home in America contains a microwave? While microwaves make meals for busy people in several seconds, is microwaving food bad for you? Over the years，this standard household appliance(家用电器）has caused much discussion. Some argue microwaves kill nutrients in your food. Is that really true?
In reality, anytime food is exposed to heat, nutrients like vitamin C and some antioxidants (抗氧化剂) can be lost. But this applies to cooking in general, not just when you’re using microwave. As is reported by WHO (World Health Organization), microwaving your food is a safe way to prepare it and it keeps the same level of nutrients as when you cook on a stove top or in the oven(烤箱).
When microwaving thicker food like meat products, WHO provides the following suggestions to ensure safe cooking methods: Cooking time will vary depending on the food itself and the power of the microwave, and will also be affected by the density of the item you are heating. Since microwave heating doesn’t evenly(均匀地)go into thick food items, meat that’s not thoroughly cooked may contain harmful microorganisms that make you sick. To kill harmful bacteria when cooking in the microwave, WHO suggests letting your food “rest” for several minutes after you finish warming it to allow the heat to give off throughout the item.
If you’re thinking about microwaving your vegetables, Harvard Health Publishing suggests heating your food rapidly, in the shortest amount of time, and as little amount of water as possible. As far as vegetables are concerned, cooking them in water robs them of some of their nutritional value because the nutrients run out into the cooking water," states the report.

【推荐2】If you have to miss a meal a day, which meal will cause you fewest health problems if you don’t eat it? If you have to make a decision of this type, most people (especially very busy people) will choose to skip breakfast.
However, many experts in the field of health consider breakfast (the meal which “break” you “fast”) to be the most important meal of the day. If we eat a good breakfast, they say, we will have the energy and nutrients we need to begin our working day with vigor and stay hopeful with good honor. However, many people skip breakfast or substitute a cup of coffee for a well balanced meal. What happens if we don’t pay attention to the importance of breakfast?
One recent study conducted in the United States tested a large number of people. Participants included both males and females in ages from 12 to 83. The results showed that if a person eats an good breakfast, he or she will work more efficiently and more productively than if he or she skips breakfast or eats a very poor breakfast. This fact appears to be especially true if a person’s work involves mental activities. The study showed that if school-children eat fruit, eggs, bread and milk before going to school, they will learn more quickly and will be able to concentrate on their lessons for a longer period of time than if their breakfast is poor.
The study also showed that if you skip breakfast, you will not lose weight. This is because people become so hungry if they skip breakfast that they eat too much for lunch and end up gaining weight instead of losing. So remember, if you want to lose weight, skipping breakfast will not help you. You will likely lose more weight if you decrease your other meals.

【推荐3】It often seems that some people possess superhuman eating powers, allowing them to eat an entire pizza while remaining slim. Others only eat a slice but gain five pounds. Now one doctor says there' s evidence that genetics could be behind some of these differences. Regardless of how much you eat, your weight may be out of control.
Vann Bennett, a biochemist at Duke University and his team led a new study and discovered why this happens. They engineered mice to have several common modifications of the gene found in humans. They observed that mice who had mutations of ankyrin-B(锚蛋白B的变异) took more glucose(葡萄糖) into their fat cells, which in turn made more fat. Typically, the cell membrane( 膜) acts as a barrier to prevent glucose from entering these cells ; the change kept the gate open. The change may serve a useful purpose. “ Probably this is not always a bad thing,” Bennett told Newsweek. “It could help people survive hunger in the past. But today we have so much food that it probably is a bad thing.”
Dieters have long been told to watch their calories and exercise more, but this new finding suggests that a common approach doesn't work for everyone. Our metabolism( 新陈代谢) naturally slows with age, making it harder to maintain the weight of our 30-year-old selves when we' re 50. Now add an uncontrollable ankyrin-B gene, and it may seem impossible to stay slim.
The mice in the study gained more weight when on high-fat diets. Despite being studied in mice, the researchers believe further research on this gene could potentially create a field of customized diets and health plans based on genetics. Bennett imagines such assessments being performed at birth one day. For now, disappointed dieters can take comfort with one saying: It's not you, it's your genes.
