Does your mouth water when you think of cookies, burgers and French fries? Many people prefer junk food like this to healthy food because they develop a taste for it. Processed, baked, and fried foods often contain a high amount of trans fats.
Trans fats raise bad cholesterol (胆固醇) and lower the good cholesterol that your body needs. Fatty foods do more than cause people to gain too much weight. Trans fats build up in the body and block blood flow to the heart. People whose diet contains a high percentage of trans fats are at risk of developing heart disease or having a stroke.
Food companies and restaurants choose to use trans fat oils because they’re cheap and they make food like crackers and baked goods last longer. They also improve the taste of food. Trans fats became very popular in the second half of the 20th century. This is around the time butter got a bad name for its cholesterol levels. People were told to use margarine (人造黄油) containing trans fats instead because it was “healthier”, but we now know that butter is actually the healthier option.
We all need some fat in our diet. There are three different types of fats: saturated (饱和的) fats, unsaturated fats and trans fats. Doctors recommend that we get most of our fatty calories from unsaturated fats. Neither butter nor margarine fit this category, though other spreads like peanut butter do. Reading the list of ingredients on the label is a good way of avoiding dangerous ingredients like trans fats. Another way is to avoid eating out, especially in fast food restaurants. Also, when shopping try to buy the majority of your food in the fresh-food section and limit the amount of processed and packaged food you buy. You might not think this is important if you’re young, but the choices you make now will affect you for the rest of your life.

【推荐1】If you feel like you can't even consider consuming a candy bar without checking its caloric content, you're right. The same thing goes for just about every piece of packaged food you see in stores, plus every bottled or canned beverage: A Nutrition Facts label shows detailed information on the amounts of fat, sugar, sodium and more found inside. But while your favorite sodas and sandwich fixings have this type of in-your-face transparency, you may have noticed that alcohol is not the case. Why?
The answer lies in the powers behind that. While the Food and Drug Administration (FDA) regulates the safety of food, including non-alcoholic beverages, it doesn't govern the alcohol industry. It is because of the Alcohol and Tobacco Tax and Trade Bureau(TTB), an agency that doesn't require labeling. The reasons behind different labeling requirements of the FDA and TTB go back to Prohibition.
While beer, wine and spirits companies aren't legally required to print the nutritional information on their products, consumer advocates have been calling for the TTB to change that. And it has, sort of. In 2013,the TTB made nutrition labels optional for alcohol. But some health experts don't feel the move was brave enough.
Sara Bleich, a public health researcher, said, “Many adults take in a lot of calories from alcohol, and they have no idea.” Her work revealed that the average American regularly consumes 400 calories a day from alcohol alone. The public should be given the power to make informed decisions about their health.
At present, substances that people might be sensitive to have to be labeled, but other ingredients do not. Wines that contain 14 percent alcohol or more have to display alcohol content, while wines from 7 to 14 percent don't have to list alcohol content. What about wines with less than 7 percent alcohol? Those aren't regulated by the TTB at all—those are under the control of the FDA and so they're required to display Nutrition Facts labels.
Change is going on though, at least the beer industry has agreed to voluntarily display nutrition facts next year. Cheers!

【推荐2】Certain Chinese cuisines, such as the well-known Beijing Roasted Duck or the delicious Tianjin-style Pancakes, have gained global recognition. The appeal of these delicacies is deeply rooted in vast geographical diversity.
Extending from the extremely cold northern plains to the southern rainforests, different regions have their unique ingredients and cooking techniques.
Climate plays a critical role in shaping regional cuisines. In Sichuan, for example, the hot and wet climate, combined with the region’s mountainous physical geography, has led to a preference for spicy foods. The spicy flavors add appetite to dishes. In addition,
One of the contrasts between southern and northern Chinese cuisines lies in the employment of ingredients. Southern dishes tend to be lighter, featuring seafood and vegetables. In contrast,
Another important aspect of Chinese dining culture is the significance of table manners. Meals are often shared among family and friends, with each person taking turns to serve and pour. Chopsticks, rather than forks or knives, are preferred, symbolizing closeness and familiarity. The act of eating together extends beyond food alone.
A.northern cuisines are heavier and more considerable |

【推荐3】People’s likelihood of being vegetarian seems to be influenced by several genetic variants, and two of the three most important genes found so far appear to be involved in fat metabolism (新陈代谢).
Genetic factors are known to influence aspects of diet, such as whether people like coffee or alcohol. To see if genes also affect vegetarianism, Nabeel Yaseen at Northwestern University in Chicago and his team turned to data on about 5300 strict vegetarians and 330,000 meat eaters. They found that three gene variants were more common in vegetarians. Two, called NPC1 and RMC1, are involved in the transport and metabolism of cholesterol and other fatty molecules. The third gene, called RIOK3, has various functions, including affecting the immune system.
It isn’t known how these genes may relate to vegetarianism. But one of the chief differences between animal-based foods and plant-based ones is the chemical make-up of their fats or oils, collectively known as lipids (油脂). Yaseen conclude that some people may function better on a vegetarian diet because they are more able to synthesize (合成) certain lipid molecules that are present in meat.
Some people who try vegetarianism but give up may be doing so because their body becomes deficient in the essential lipids, says Yaseen. “They decide that this diet is not for them or gradually go back into an omnivore (杂食) diet. Some people might think they just don’t have the willpower.”
Another possibility is that the apparently vegetarianism-promoting gene variants affect people’s taste. “Alot of information about genes is yet to be known,” Yaseen says.
Richard McIlwain at the UK Vegetarian Society says the number of vegetarians has almost doubled in the UK between 2012 and 2019. “That would seem to suggest something other than potential genetic factors are at play,” he says. “People go vegetarian because, more and more, they are concerned about climate, about animal welfare or about their health,” he says, which are more important determinants than physiological factors.

【推荐1】Parents Model Healthy Eating
It should come as no surprise that the more stressed parents are at work, the greater the burden on their family is.
For years, most studies have focused on the role of working mothers while fathers were ignored. They didn’t look at the family as a whole.
Mom’s work related stress is still a central factor in low well families eat because they typically do most of the food shopping and cooking.
It’s worth nothing that the study looked mainly at low income families who belonged to ethnic(民族的)or minority groups.
A.And the role of fathers in particular |
B.But dad’s work related stress has a large impact, too. |
C.Yet, the kids’ stress may influence the families’ nutrition, too. |
D.So the findings don’t necessarily apply directly to other types of families. |
E.When it comes to family nutrition, the entire family plays a role even kids. |
F.It’s also probably not a surprise that this can negatively affect a family’s nutrition. |
G.It is parents who give their kids a good model to develop a good eating habit. |
【推荐2】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.

【推荐3】Protein plays an important role in anyone’s health.But if you’re trying to build muscle, you’ll have to take more of it.The following is an introduction to what you should pay attention to about eating protein.
If you think the more protein you eat, the more muscle you will get, think again. It is possible to have too much of it.
It can be difficult to say how much is too much, as protein needs can be different so greatly from person to person.For common persons it’s generally best not to take more than 2 grams per kilogram of body weight.
When making any change to your food, it’s always a good idea to talk to your doctor.What’s more, if you’re uncertain about the protein needs, you may want to talk to a doctor to get some personalized suggestions.
A.Do the sources of your protein matter? |
B.For example, it may damage your liver. |
C.These bad results, however, can be ignored. |
D.These foods are known as complete proteins. |
E.You can get amino acids from eggs, meat and so on. |
F.Therefore, it’s important to know how much you really need. |
G.However, it may be safe for an athlete to take more than that. |
【推荐1】Ever look at your to-do list and want to run and hide? Me too. But life is more than working hard to finish tasks, collapsing into bed, judging the past 24 hours and our success by how much we've managed to tick off.
So here’s how to get stuff done and enjoy yourself at the same time.
1.Rename it My friend Jim Kwik says, “Call your ‘got-to-do’ list your ‘get- to-do’ list.” It’s a tiny change but a major shift. Think about it. You get to walk your dog, choose wonderful dinner ingredients and go to a job each day that affords you the life you have. ![]() |
2.Add some action Instead of writing plain reminders down as memory urges, like “Dentist” and “Report,” add some verbs and result-based benefits, like “Book dentist and get teeth sparkly white!” or “Complete report and let out your breath.” Imagine the good feeling attached to each agenda item and let it fuel you. |
3. Trust there’s time Have you ever noticed when you’re in a rush, you make mistakes? Like when you’re late for work: You can’t find your jeans, you hurt your toe on the bed by accident and you misplace your phone as you head down the elevator. When we operate from a place of calm, stuff happens faster. We find what we need. We don’t burn the toast. It can be as simple as sitting up in bed, taking ten deep breaths when you wake up and setting a simple intention for the day (not reaching straight for Instagram and email). |
4.Ask yourself this How are you spending your days, your life? Are you having enough fun? Can your got-to-do list be a get-to-do list with some good moods dancing on the page and an air of “I got time!” attached to it? Yes, it probably can. Now, what’s first? |

【推荐2】Scientists have already applied robots like Roomba to work in the agriculture (农业). A Roomba works because it has wheels that function well on flat ground. However, fields are full of rough and rocky environments, which means it is difficult for robots to work in the fields. Luckily, scientists thought of centipedes (蜈蚣). With tens to hundreds of legs, they can move on any places without stopping. If they stop moving their body parts and feet, they basically stop moving instantly.
A team led by Chong developed a theory that proposes that adding leg pairs to the robot increases its ability to move firmly over challenging environments.
To test this, Juntao conducted a series of experiments where he and Daniel Soto built models to simulate (模拟) different natural environments. He then tested the robot by increasing its number of legs by two each time, starting with six and finally increasing to 16. As the leg count increased, the robot could more easily move across the surfaces, even without sensors. Finally, they tested the robot outdoors on real environments, where it was able to move in a variety of environments.
The researchers are applying their discoveries to farming. Goldman has co-founded a company that wants to use these robots to weed (除草) farmland where weedkillers are ineffective. “It’s truly impressive to see the multilegged robot easily moves on both lab-based and outdoor environments,” Juntao said. “Now we are deciding the most suitable number of legs to achieve motion. In the future, we hope to apply them for space exploration, and even search and rescue.”

【推荐3】Elephant, horse and cow wastes could be endless sources for a key element needed to make paper. It is good news for some nations where trees are scarce while animal wastes come in especially handy.
The idea for the unusual use of elephant and cow wastes first came to mind when researcher Dr Alexander Bismarck noticed something strange about goat wastes while vacationing in Greece. He observed some goats eating summer-dry grass and came to an interesting conclusion about what they digest.
Dr Bismarck said: “I realized what comes out in the end is partially digested plant matter so there must be cellulose (纤维素)there". Animals eat dry grass containing cellulose, chew it and digest it in their stomach and then produce wastes. Up to 40 percent of those wastes are cellulose, which is easily accessible. Therefore, making paper from the partially digested material would take much less energy than using raw wood. Additionally, it would require fewer chemical treatments.
This supply of raw material is plenty: parks in Africa that are home to hundreds of elephants produce tons of wastes every day, and enormous cattle farms in the US and Europe produce mountains of wastes.
In order to make paper, the material must be processed with a special method. But it requires little because there is no need to break it down into small parts for use in paper, in contrast to conventional methods which need a lot of energy to break down wood.
Using wastes, we can reduce the number of steps needed in papermaking, simply because the animal already chewed the plant and attacked it with acid in their stomachs. You inexpensively produce a paper staff that has the same or even better properties than that from wood, with lower energy and chemical consumption.
