2 . In your family you may find it difficult to form new eating and exercising habits for yourself without changing their habits at the same time.
Your family may prefer high-sugar and high-fat foods. But they don’t realise the fact that those foods have negative influence on the heart and blood pressure. So you should first let the whole family know the importance of changing bad eating habits. It is evident that low-sugar and low-fat foods contribute to good health.
In order to get the entire family’s support for changing eating habits, you should try to put your new lifestyle into your family’s routines. Perhaps your parents or other family members don’t want to abandon their favourite dishes. But you can advise your family to adjust their favourite recipes by gradually reducing fat and sugar. It may be an effective start to change their eating habits.
Your family may prefer watching TV in spare time. To deal with it, you should persuade everyone to move away from the television little by little. For example, you can begin by taking a walk with them, then move on to more activities like jogging or swimming.

Scientists have developed a necklace (项链) described as the “diet choker”. The WearSense necklace can keep eyes on everything that goes into your mouth, and sends you a caution to warn you not to go on eating if you overeat. WearSense has a special sensor (传感器), which uses the vibrations (振动) on your neck to tell when you are eating and drinking.
The researchers have connected it with a smart-phone app which sends a signal if you go over your daily calorie limit. It also lets you know if you eat too much of the wrong kind of food. The team said WearSense works because each food makes a different type of vibrations on the neck, so the necklace is able to work out what it is you’re eating using the sensor, which measures changes in pressure or force.
In tests with a limited menu, the WearSense necklace has guessed the difference between solid and liquid foods with 90 percent accuracy (准确度). It could also tell between hard and soft foods about 75 percent of the time.
The necklace asks the user’s age, height, weight and their goal such as to lose weight or stay the same. It will then tell them what they have eaten, how fast they eat their food and gives them advice－such as if you miss a meal, it tells how it could leave you tired.
The research said that other usage they could see for the necklace included when somebody takes a pill it can ensure they take pills on time. Even smokers who are trying to quit could benefit from the necklace, as it could tell if they are smoking from the movement in their neck.

I couldn’t sleep at all last night. My sister says it was because I ate a bowl of really spicy chili (辣的辣椒) right before bedtime, but I think that’s impossible. Can spicy foods at bedtime really have an influence on one’s sleep?
－Sleepless
Dear Sleepless,
I know your feeling because I often eat spicy chili before lights out. I’ve also experienced sleep problems after eating a lot of spicy foods. What does science say?
Researchers in Australia did an experiment to find out the effects of spicy foods on how we sleep. They wanted to try to know the influence of spicy foods on the length or quality (质量) of sleep. They gave a group of people delicious late-night meals. Some nights, they got spicy meals. Other nights, their meals were mild (清淡的). It turns out that your sister is on to something. When the people taking part in the experiment ate spicy foods, their sleep patterns (模式) were changed. They took longer to fall asleep and they slept less, too. This was the kind of information the researchers were looking for to build a link (关联) between eating spicy foods and possible sleep problems.
Researchers aren’t sure exactly how spicy foods change sleep patterns, but they have some ideas on the subject. People’s sleep could be influenced because of stomachache caused by eating spicy foods. Also, they could be taking too long to fall asleep because of taking too long to digest (消化) the spicy foods. But they also guess that body temperature plays a role. Spicy foods include something that can raise the body’s temperature. Other studies have connected increased body temperature with poor sleep. So before you go to bed, leave the chilies alone and sleep well.

5 . Does drinking alcohol really help us stay healthy? If so, how much should we have each day? Recently a study, co-authored by 512 researchers from 243 institutions, was published in the well-known journal The Lancet. The researchers built a database of more than a thousand alcohol studies and data sources, as well as death and disability records from 195 countries between 1990 and 2016. The goal was to see how alcohol affects the risk of 23 health problems. The number that jumped out, in the end, was zero. Anything more than that was associated with health risks.
"What has been ignored is that no amount of drinking is good for you," said Emmanuela Gakidou, a professor at the University of Washington. "People should no longer think that a drink or two a day is good for you. What's best for you is to not drink at all," she said. The study found that 2.8 million people across the globe died in 2016 of alcohol-related courses. For people aged 15 to 49, alcohol is the leading risk factor for experiencing a negative health outcome.
This is an alarming report for the roughly 2 billion human beings who drink alcohol. The report challenges the controversial assumption that moderate drinking provides a clear health benefit. That idea took hold in the 1990s after news reports on the "French paradox": The French have relatively low rates of heart disease despite a fatty diet. Some researchers pointed to red wine consumption among the French as potentially protective.
A large number of studies found evidence that people who have a drink or two a day are less likely to have heart disease than people who give up or drink too much. But the new study, while noting the lower risks of heart disease from moderate drinking, found that many other health risks balance out health benefits. Those include the risks of breast cancer, interpersonal violence, self-harm and transportation accidents.
