It is well established that eating vegetables is good for us. Why, then, do some people like them but others don’t? A new study has found that other people’s likes and dislikes could play a part. According to the research, people who eat vegetables and show an obvious distaste for them can influence others.

A team of scientists in the UK set out to investigate how the facial expressions people make as they eat affect a person watching them. They asked more than 200 young women to watch videos of other adults eating raw broccoli. The people in the videos had different expressions while eating. They would smile, seem neutral (neither happy nor sad), or look disgusted by what they were tasting.

The study found that participants who watched someone else react with disgust while eating broccoli began to like broccoli less. The opposite was not true, however. When someone had a positive facial expression while eating broccoli, people watching them did not end up liking broccoli more.

Humans learn which behaviors, including eating, will benefit them by watching the reactions of others. Known as social modeling, this tendency can have a strong influence on people’s eating habits. Scientists believe that people might avoid food that appears disgusting because it could help protect them from eating something that tastes bad or could even be dangerous.

Although the research focused only on adults, experts think the results could also apply to children. This means that if children see their parents or siblings not enjoying certain foods, including vegetables, they might not want to eat them either. A previous study found that children between the ages of 4 and 6 were more likely to eat broccoli if they had seen video clips of adults enjoying it.

The team said further research is needed to understand more about how the behavior of adults influences children’s enjoyment of food. This could help experts find ways to encourage young people to eat more of the foods that are healthy for them.

A trip to the theater, museum or art gallery could help you live longer. And the more often you get that culture, the better the results are, a new study suggests.

Researchers from University College London (UCL) did the research on more than 6,000 adults in England age 50 years and older. How often an individual engaged in art activities was measured at the start of the study in 2004 to 2005. Participants were then followed up for an average of 12 years, during which time deaths were recorded using data from the UK’s National Health Service (NHS). They found that people who engaged in the arts more frequency had a 31% lower risk of dying early when compared to those who didn’t. Even going to the theater or museum once or twice a year was linked with a 14% lower risk.

The study looked at a range of economic, health and social factors to try and explain why there is a link between “arts engagement and living longer. Part of the reason, the study said, comes down to social and economic differences among those who go and don’t go to museums, exhibitions and art galleries. Wealth, they found, explained about 9% of the association. Cognitive (认知的) differences and mental health also played a role. Things like free time and occupational status made no difference, said Fancourt.

Engaging with the arts can act as a buffer against stress and build creativity that allows people to adapt to changing circumstances. It also helps people access emotional support and information that helps people age more successfully. “We also thought that a greater sense of purpose could play a role,” she said. “It can have wide ranging benefits and support healthier lives lived longer.”

A world health organization last year found that both receptive participation, like visiting a museum, and active participation, like singing in a choir, had health benefits. An editorial that accompanied the paper said that everyone should have the chance to take part in cultural activities and said the study added weight to growing concerns about the decline in arts subjects in schools and universities.
