While sweet treats can be hard to resist, the World Health Organization(WHO) has set new guidelines for people around the world. The guidelines, released on Wednesday, advise that both adults and children cut back on their sugar intake(摄取量) to stay healthy.

    In a statement, Francesco Branca, director of the WHO's nutrition department, said there is evidence that reducing daily sugar intake reduces the risk of being overweight and tooth decay(腐烂).

    The guidelines do not apply to the sugars in fresh fruit and vegetables or those that are naturally present in milk. According to the WHO, there is no reported evidence of negative effects of consuming those sugars. Instead, the new guidelines focus on “added” or “free” sugars. These include sugars that are added to processed foods and drinks such as candy and soft drinks.

    Added sugars are sometimes described as “ hidden” sugars because they exist in foods we might not think of as sweets, such as honey and ketchup(番茄酱). Health experts advise that consumers look at ingredients on food packages to help make better-informed decisions.

    The WHO recommends that people in the United States, Europe and other Western societies should cut their average sugar intake by about two-thirds, or down to just 10% of their overall calories. For developing countries, where dental care is less advanced, the WHO recommends that sugar intake be reduced to 5%.

    Scientist Kieran Clarke, of the University of Oxford, notes that for those people who can't shake their love for sweets, getting more exercise is a good solution. “If you get enough exercise, you can eat almost anything,” she said “But it's very hard to avoid large amounts of sugar unless all you're eating is fruit and vegetables.”

    If you want to convince the boss you deserve a pay rise or promotion, the solution could be simple —eat the same food as they do. Psychologists have discovered managers are much more likely to instantly trust us if we choose the same dishes as them.

    During experiments, discussions over wages and work conditions were much more successful if both sides chose to snack on the same treats. And shoppers were much more likely to buy a product advertised on TV by someone eating a similar food to them at the time.

The reason is thought to be so - called similarity attraction theory—where people tend to like others who have similar tastes or habits to themselves. But this is believed to be one of the first studies highlighting the role of food in this relationship. Researchers at Chicago University in the US conducted a series of experiments to examine food's role in earning trust.

In a test, participants were told to watch TV — where someone pretending to be a member of the public praised a certain product. The volunteers were given Kit Kat bars to nibble, while the TV people ate either a Kit Kat or grapes as they talked.

    The results showed viewers were much more likely to express an interest in buying the product if the TV showed the other person eating a Kit Kat too.

    The researchers added, “Although similarity in food consumption is not a sign of whether two people will get along, we find consumers treat this as such. They feel more trusting of those who consume as they do. It means people can immediately begin to feel friendship and develop a bond, leading to smoother transactions from the start.”

    Harley Street psychologist Dr Lucy Atcheson said it was already known that wearing similar clothes could instantly create trust. But this was the first report that food had the same effect. She said, “This is really interesting. It makes sense as people feel they have common ground and can trust the other person. That means negotiations are more likely to be successful.”

    Many of you may have used Siri, a voice assistant of US tech company Apple. You only have to say "hey Siri" and it will answer to your command. However, we may be sacrificing our privacy to enjoy this convenience.

    According to a recent report by the Guardian, Siri can be accidentally triggered and start recording private conversations, such as discussions between doctors and patients. Some of these recordings are then given to workers outside the company to review.

    Apple claimed the data was used to help Siri improve, but users were not informed of this measure in the first place.

    Apple's Siri is not the only voice assistant to come under fire.

    In 2018, Alexa, a voice assistant developed by US tech company Amazon, recorded a private conversation between a couple and sent it to a stranger without their permission.

    These issues deepened concerns that tech companies are infringing users' rights of privacy.

    Many people have long feared that tech companies are listening and collecting data from private conversations, reported Forbes. Using this data, third party companies could then paint an accurate picture of users' habits and preferences in order to serve them more targeted advertisements, or even worse, sell this private data.

    Despite this risk, the popularity of voice assistant seems to be unstoppable.

    "In the near future, everything from your lighting to your air-conditioning to your refrigerator, your coffee maker, and even your toilet could be wired to a system controlled by voice," commented The Atlantic.

    Colin Horgan wrote on the blog site Medium that he believed people's daily lives will soon become a source of data.

    "The sounds of our homes, the symphony of life – laughing, crying, talking, shouting, sitting in silence – will no longer be considered memories, but data," he wrote.

    To deal with the issue, Blake Morgan, reporter for The Atlantic, believed that the answer is transparency.

    "All companies need to have messaging ready to explain to customers what they do with private data," she wrote on The Atlantic.
