Why do we overeat?
Marion Nestle is a consumer activist, nutritionist, and academic who specializes in the politics of food and dietary choice. Nestle received her BA, PhD, and MPH from the University of California, Berkeley. In 1988, Nestle was appointed Chair of New York University’s Steinhardt School of Nutrition, Food Studies, and Public Health. She held that position until 2004, when she became the Paulette Goddard Professor in the same department.
Nestle is the author of numerous books, including "Food Politics," which explored the way corporations influence our nutritional choices, and "What to Eat," an survey of how to navigate the modern American supermarket. Aside from her books and teaching, Nestle writes a popular blog for the Atlantic Food Channel.
Marion Nestle: Actually there’s very good research now that shows why people overeat. It turns out that anybody, no matter how educated you are about it – even me – I will overeat if I’m presented with a large amount of food. In fact you can demonstrate that the larger portion of the food presented to somebody, the more calories they will eat from that food even if they don’t finish it. Food that is closer to you will be consumed in larger amounts than food that’s further away. Food in wide, fat glasses will be consumed in greater number of calories than in tall, thin glasses. I mean there are all kinds of sort of visual and little tricks that companies use to get people to eat more food. They knew all of this. We’ve only learned about it recently through the work of people doing terrific research.
People are more likely to eat more the more food is in front of them.
A pragmatic approach to fixing an imbalanced system.
- Intentional or not, certain inequalities are inherent in a digital economy that is structured and controlled by a few corporations that don't represent the interests or the demographics of the majority.
- While concern and anger are valid reactions to these inequalities, UCLA professor Ramesh Srinivasan also sees it as an opportunity to take action.
- Srinivasan says that the digital economy can be reshaped to benefit the 99 percent if we protect laborers in the gig economy, get independent journalists involved with the design of algorithmic news systems, support small businesses, and find ways that groups that have been historically discriminated against can be a part of these solutions.
Is there a way for more human-centered algorithms to prevent potentially triggering interactions on social media?
- According to a 2017 study, 71% of people reported feeling better (rediscovery of self and positive emotions) about 11 weeks after a breakup. But social media complicates this healing process.
- Even if you "unfriend", block, or unfollow, social media algorithms can create upsetting encounters with your ex-partner or reminders of the relationship that once was.
- Researchers at University of Colorado Boulder suggest that a "human-centered approach" to creating algorithms can help the system better understand the complex social interactions we have with people online and prevent potentially upsetting encounters.
