Christina A. Roberto, Ph.D. is an Assistant Professor of Medical Ethics & Health Policy at the Perelman School of Medicine at the University of Pennsylvania. Dr. Roberto is a clinical psychologist and epidemiologist. She is the director of the Psychology of Eating And Consumer Health (PEACH) lab. Her research aims to identify and understand factors that promote unhealthy eating behaviors linked to obesity and eating disorders and design interventions to promote healthy eating. In her work, she draws upon the fields of psychology, marketing, behavioral economics, epidemiology, and public health to answer research questions that can provide policymakers and institutions with science-based guidance.
National Institutes of Health Funds Monumental Mitzvah Food Program Study
“This research study will be the first to rigorously evaluate the long-term behavioral and health effects of low-cost healthy food ‘nudges’ in a food pantry,” said Christina Roberto of the Perelman School of Medicine’s Psychology of Eating and Consumer Health (PEACH) lab, who is leading the study. Using our online ordering system, Penn’s multiyear randomized-controlled trial will examine how food pantry clients are influenced by on-screen interventions, or “nudges.” In other contexts, nudges — like adding traffic light colors to signal healthy and less-healthy choices — have successfully led to healthier food choices.
Soda ad blitzes conspicuously match food stamp schedules, study says
Food companies have embraced a controversial tactic in their quest to sell more soda, a new study says: timing advertisements for sugary drinks to the days states distribute food stamp benefits. On any given day, grocery shoppers are likely to see soda displays in stores, researchers found. But they are two to four times as likely to come across them when food stamps go out.
Sodium content needs to be on the menu at Philly restaurants. Here's why
New legislation proposed last week by Councilwoman Blondell Reynolds Brown will help Philadelphia restaurant-goers reduce their risk of stroke and heart disease.
Philly's soda tax has spawned multiple studies. Here's what we've learned
Penn researchers analyzed beverage prices at stores and restaurants in Philadelphia and outside the city to determine how much of the 1.5 cents-per-ounce tax was passed to consumers.
NYC Calorie Rule Scrutinized in Courts of Law, and Science
As a court fight simmers over New York City's pioneering requirement for calorie counts on chain restaurant menus, scientists say the jury's still out on whether giving people the numbers spurs them to eat healthier. The city says that by requiring eateries to tell people that their $4 cheeseburger will also cost them about 540 calories, it's helping diners make informed choices in an era of rising obesity.
Closing the Scholarship-Policy Gap with Strategic Science
This summer the Trump administration announced further delays in (1) implementing calorie labels on restaurant menus across the nation and (2) rolling out a new nutrition facts label.
Nearly all businesses that serve food will have to disclose calories on their menus starting in May
Adding calorie counts on menus might make Americans eat better — but not in the way you’d think
