New Study Shows How Motivation Affects Diet

A new study suggests that people with a positive attitude are more likely to eat healthily.

Led by researchers at the University of East Anglia (UEA) in England, the study involved 1,125 people in Taiwan, where dietary habits have been changing, leading to increases in obesity, high blood pressure, and diabetes. Participants were questioned about their nutrition involvement and knowledge, as well as adjustments to their diets.

Researchers examined the motivational role of a theory called regulatory focus on consumers’ involvement in nutrition. That theory looks at the time and effort people put in to finding out about nutrition and seeking out nutritious food.

The researchers also examined the effect of nutrition involvement on consumers’ knowledge of nutrition and dietary behavior.

Regulatory focus suggests that there are fundamental motivational differences among people, with two aspects — promotion and prevention — guiding behavior, according to the researchers.

Those with a promotion focus are concerned with pursuing positive outcomes, such as engaging in healthy behaviors, while those with a prevention focus seek to prevent negative consequences, for example by avoiding unhealthy behaviors, the researchers explain.

The study’s findings show that having a promotion focus leads to consumer’s involvement in nutrition, which in turn leads to nutrition knowledge and diet adjustment following advice, for example from media, doctors, family members, or friends.

Researchers found that having a prevention focus had no effect on nutrition involvement.

The study also found that the effect of promotion focus on nutritional involvement was greater among high-income consumers.

The findings also suggested that the effect of promotion focus was stronger among men than women, but the researchers say this is to be expected because previous research has shown that women have higher levels of nutritional involvement, irrespective of having a promotion focus.

The findings provide insights about nutrition-related consumer attitudes and behaviors, which is important given the growing rates of obesity and conditions such as diabetes, said lead author Kishore Pillai, Ph.D., a professor of retail and marketing at UEA’s Norwich Business School.

“The higher aspirational levels of promotion-focused consumers will lead to greater involvement with nutrition to enhance their well-being,” said Pillai. “While both promotion and prevention focused individuals will be motivated to maintain good health, the former are more likely to employ approach strategies, such as nutritional involvement.

“Consumer decisions regarding eating behaviors and nutrition can lead to consequences such as illness and obesity that have direct public health policy implications,” Pillai said. “Obesity is preventable and increasing consumer involvement in nutrition can help achieve this.”

According to Pillai, consumers are likely to receive advice on nutrition from a number of sources in their daily lives.

“Public agencies can encourage promotional focus and in turn involvement in nutrition through appropriate communication. But, as the results of this study indicate, the effectiveness of this intervention will vary between high and low income groups and is likely to vary between males and females.”

“Given the problems of obesity and illnesses directly linked to unhealthy eating habits, the direct effect of nutrition involvement on dietary behaviors demonstrated in this study underscores the importance of investing in efforts to promote nutrition involvement from a public health policy perspective,” Pillai added.

The study was published in the journal Appetite.

Working Remotely Is Not Necessarily Stress-Free

Many believe that working from home or remotely can foster freedom and stress-free job satisfaction, and that everyone wants  more work autonomy. A new study from Baylor University in Waco, Texas, says “Not so fast.” In the study, researchers examined the impact of remote work on employee well-being. Their findings suggest that a variety of factors can undermine or accent the employee benefits of working off-site. Accordingly, researchers developed new strategies to help managers provide remote-work opportunities that are valuable to the employee and the company. “Any organization, regardless of the extent to which people work remotely, needs to consider well-being of their employees as they implement more flexible working practices,” the researchers wrote. The study appears in the European Journal of Work and Organizational Psychology . In the review, a total of 403 working adults were surveyed for the two studies that made up the research, said lead author Sara Perry, Ph.D. Re

Today’s Popular Music is More Angry, Sad and Less Joyful

Today’s popular music is noticeably different from the popular songs of the 1960s and 1970s. Now a new study reveals that it’s not just the music itself that is different; today’s music consumers seem to prefer songs that express darker emotions in both lyric and tone. The findings, published in the Journal of Popular Music Studies , show that the expression of anger and sadness in popular music has increased gradually over time, while the expression of joy has declined. Using quantitative analytics, researchers from Lawrence Technological University in Michigan studied changes in popular music lyrics throughout the last seven decades, from the 1950s to 2016. Data scientists Kathleen Napier and Dr. Lior Shamir analyzed the lyrics of more than 6,000 songs found on the Billboard Hot 100, a list of the most popular songs of each year. In the past, songs were ranked primarily by record sales, radio broadcasting, and jukebox plays, but in more recent years, popularity is based on several

I Pretend that Fictional Characters Are Real & Talk to Myself as Them

I’ve always loved to play pretend. But now that I’m a teenager, instead of outgrowing it, it’s gotten worse. Now I’ve gotten to the point where it’s an obsession, and I spend more time with my imaginary friends then with real people. I pretend that my favorite characters from movies and TV shows are real, and I talk to myself, both as myself and the character. I have long discussions with myself. I also pretend that they are with me everywhere I go–to the supermarket, to my cousin’s house. I pretend that they’re with me, no matter what I do. Lately, I’ve also been doing something that’s hard to explain: I pretend to be two people (usually myself and my mother, or a cousin, or a made-up person) and have a pretend to have a conversation with them. I pretend that the fiction character is watching me and my mother/cousin/other. Usually, those scenarios involve either a verbal fight, or joking. I’m really concerned because I know this is abnormal and I’m not living a normal life. I’m worri
