  • Nutrition Policy Institute presentation at the NIH ‘State of the Science’ workshop on Food Insecurity, Neighborhood Food Environment, and Nutrition Health Disparities is now available online

    Oct 8, 2021

    Nutrition plays an important role in promoting health and preventing disease, but where people live or how much money they earn can affect their ability to access or afford healthy food. Understanding the role socio-economic conditions play can help inform prevention efforts. Nutrition Policy Institute director and Cooperative Extension specialist, Lorrene Ritchie, presented at a three-day virtual National Institutes of Health workshop, “Food Insecurity, Neighborhood Food Environment, and Nutrition Health Disparities: State of the Science”. Her talk, “Food Insecurity Across the Lifespan,” provided an overview of current evidence related to racial/ethnic and socioeconomic disparities of food insecurity over the life course. All talks are free and available on-demand for online viewing.

  • Nutrition Policy Institute’s Wendi Gosliner featured in Western Farm Press article on text messages to CalFresh participants on healthy produce

    Oct 6, 2021

    Nutrition Policy Institute senior researcher and policy advisor, Wendi Gosliner, was featured in an article in Western FarmPress about a pilot program for San Diego County CalFresh participants to receive monthly text messages about the benefits of California-grown fruits and vegetables. Gosliner worked to evaluate the pilot program in collaboration with the UC San Diego Center for Community Health and the County of San Diego Health and Human Services Agency. Gosliner is quoted as, “In a text, you have very few characters you're communicating with people, so we wanted to make sure we were using cutting-edge behavioral science to construct those messages to have the most impact." A majority of the program recipients who received messages from September 2020 to March 2021 responded to a survey saying they appreciated receiving the text messages. Gosliner reports, “What we see is that there's definitely a decent-sized population of people participating in CalFresh – now this is just in San Diego County but imagine the entire state – who would benefit from having this kind of information available to them, and there is at least a subset of people who really liked it."

  • UC Berkeley student named Global Food Initiative Fellow with Nutrition Policy Institute

    Sep 30, 2021

    University of California student Anna Rios has been selected as Global Food Initiative fellow for the UC Agriculture and Natural Resources Nutrition Policy Institute during the 2021-22 school year. Rios is a senior in molecular and cell biology at UC Berkeley. Rios is originally from the small rural town of Williams, about two hours north of the Bay Area. In her home community, she noticed the prevalence of packaged and processed foods, along with health burdens present. Coming into college, Rios had no interest in research, but this slowly shifted as she gained more exposure to research through her involvement with Lorrene Ritchie, director of the Nutrition Policy Institute. In this upcoming year, she will work on two GFI projects which focus on improving nutrition in infants and school-aged children through nutritious school meals. The Global Food Initiative was founded in 2014 under then UC President Janet Napolitano with the goal of conquering the question of how to sustainably and nutritiously feed a world population that is expected to reach 8 billion by 2025. Fellows across the 10 UC campuses and Agriculture and Natural Resources work on projects or internships that focus on food issues. Participants receive professional development, tours of food and agriculture sites throughout California, and a $3,000 annual stipend to support their educational experience.

  • More than 1.8 million Californians are still behind on rent payments despite progress protecting California renters from eviction during the pandemic

    Despite progress on protecting California renters from eviction during the COVID-19 pandemic, more than 1.8 million Californians are still behind on rent payments. New findings from University of California researchers suggest more outreach on California's emergency rental assistance (ERA) program is needed. Wendi Gosliner, of the University of California, Division of Agriculture and Natural Resources, Nutrition Policy Institute, partnered with researchers at UC Berkeley and the UCSF Benioff Homelessness and Housing Initiative to collect survey data on 502 low-income parents of young children residing in California. Survey results found that 22 percent of respondents who were renters deferred rent payments since March 2020, when the pandemic first began to trigger large-scale shutdowns and economic dislocation in the United States. Only 7 percent of survey respondents had received ERA relief payments during the time of interviews. Statewide, many low-income renters remain at a heightened risk of dislocation and potential homelessness when California's eviction moratorium expires on September 30. Survey findings are compiled in a research brief, which includes recommendations for how public and nonprofit entities in California can improve ERA uptake among low-income renters. The survey, part of the Assessing California Communities' Experiences with Safety net Supports (ACCESS), was funded by the Robert Wood Johnson Foundation with supplemental funding from the UCSF Center for Vulnerable Populations and Tipping Point.

  • Nutrition Policy Institute partners with UC researchers to identify promising practices to support the health of California agriculture workers

    Sep 14, 2021

    Nutrition Policy Institute researcher, Ron Strochlic, received funding to partner with researchers from the University of California (UC) to identify promising practices to support the health of California agriculture workers. Strochlic, a longtime researcher of California agriculture worker health issues and former executive director of the California Institute for Rural Studies, will be conducting interviews with growers and farm labor contractors, as well as stakeholders representing different sectors–farm labor advocates, farmworker-serving nonprofits, grower organizations and health care providers–on agricultural worker health. The goal of the interviews is to identify promising practices for increasing access to and utilization of health care services among agricultural workers and their family members, as well as access to wellness services, including nutrition and physical activity. Strochlic will be working with Christy Getz, UC Berkeley Cooperative Extension Specialist in Agriculture and Food Systems, to interview stakeholders. The interviews are part of a larger project, known as the Farmworker Health Study, led by the UC Merced Community and Labor Center. Findings will be shared with the California Department of Public Health with recommendations for improving farmworker health. The two-year project, funded by UC Merced, started in March 2020. Additional project collaborators include Paul Brown, Ed Flores, and Anna Padilla of UC Merced, and Brenda Eskenazi of UC Berkeley.

  • New NPI report details methods used by California Local Health Departments for documenting SNAP-Ed–CalFresh Healthy Living–interventions

    Sep 13, 2021

    The USDA's Supplemental Nutrition Assistance Program-Education (SNAP-Ed) is an evidence-based program that helps low-income individuals live healthier lives through education, social marketing, and policy, systems, and environmental (PSE) changes. Known as CalFresh Healthy Living (CFHL) in California, SNAP-Ed is overseen by the California Department of Social Services and implemented by four state implementing agencies and the local implementing agencies (LIAs) that they fund. The California Department of Public Health (CDPH) is one of four state implementing agencies and funds 60 local health departments. Beginning in 2018, California's LIAs use the Program Evaluation and Reporting System (PEARS) to report their CFHL activities and interventions. The Nutrition Policy Institute serves as CDPH's evaluation contractor for its CFHL program; NPI's PEARS team, Carolyn Rider, Janice Kao, Evan Talmage, and Christina Becker, provide technical and evaluation assistance to CDPH and its LIAs for PEARS reporting. They authored a  new report which presents the background, definitions, and methods used by CDPH and its funded local health departments for reporting CFHL interventions implemented throughout California during Federal Fiscal Year 2020. The report, titled “Background on Local Health Department Reporting of CalFresh Healthy Living Programs in the Program Evaluation and Reporting System, FFY 2020”, also details challenges in reporting CFHL activities and gives recommendations to improve reporting. 

  • NPI’s Lorrene Ritchie quoted in The Washington Post article on increase in childhood obesity rates during the COVID-19 pandemic

    Sep 3, 2021

    Childhood obesity rates increased during the global COVID-19 pandemic according to a study published in August in the Journal of the American Medical Association. Results of the study, which included electronic medical record data of 200,000 children ages 5 to 17 in Kaiser Permanente Southern California, were featured in an August 31, 2021 article in The Washington Post. Nutrition Policy Institute director and cooperative extension specialist Lorrene Ritchie was quoted in the article, “before the coronavirus, studies showed that students tended to gain weight during the summer when away from school. They tend to gain weight at an accelerated rate, then during the school year their body mass index goes down, but not as much, so over time kids are getting more and more overweight and obese.” Ritchie also stated that “regular summer weight gain among students is attributed to missing recess, P.E. and school sports, as well as not getting exercise associated with traveling to and from school. It is also because studies show that school meals are, on average, healthier than what children bring from home. Also, kids in school have access to breakfast and lunch; at home during the summer there is frequently unfettered access to food all day long.” Ritchie was further quoted that “companies selling junk food have had more access during the pandemic to market directly to children who spent more time on screens. What this has taught us is that our food environment is way out of line with what we need. Food companies are geared to getting us to eat as many calories as possible. And we are geared toward eating when food is available.”

  • Study by Stanford and NPI researchers describes barriers and best-practices for school districts offering meals during the COVID-19 pandemic despite school closures

    Aug 19, 2021

    Meals provided to children at schools–funded by the USDA–help mitigate childhood food insecurity. Despite COVID-19 related school closures beginning March 2020, school districts across California continued to offer meals to children and families. In a recent community-based participatory research study published in the journal Public Health Nutrition, researchers at Stanford and the University of California (UC) Nutrition Policy Institute (NPI) describe challenges and best practices in providing and accessing school meals during COVID-19. Researchers interviewed food service directors, school superintendents, and community partners, and conducted parent focus groups in English and Spanish, in six school districts in California's San Joaquin Valley–a region of predominantly low-income, Latino immigrant families. For schools, the leading barriers were developing safe meal distribution systems, boosting low participation, covering COVID-19 related costs and staying informed on policy changes. Families named transportation difficulties, safety concerns and lack of fresh food as major barriers to taking school foods. Researchers also identified pandemic-electronic benefit transfer (P-EBT), bus-stop meal deliveries, community meal pick-up locations, batched meal service and leveraging partner resources as innovative strategies for continuity in offering meals despite school closures. The study was conducted in partnership with two non-profit community organizations–Cultiva La Salud and Dolores Huerta Foundation–that work towards health equity and social justice in the San Joaquin Valley. The paper's authors were Ashley Jowell, Janine Bruce, Gabriela Escobar, Valeria Ordonez and Anisha Patel of the Stanford University School of Medicine and Christina Hecht of NPI. The study was funded by the Stanford Center of Excellence in Diversity in Medical Education and Office of Faculty Development and Diversity, Stanford Medical Scholars Research Program, the American Heart Association Voices for Healthy Kids, and the San Joaquin Valley Health Fund.

  • New report details the development and implementation of a first-of-its-kind campus-wide nutrition policy at UC Berkeley

    Aug 11, 2021

    In the United States, over 25 million people work and learn at colleges and universities, consuming an untold number of meals, snacks, and beverages while on campus. Unlike in K-12 schools, higher education institutions are not governed by federal policies to ensure that foods and beverages sold on campus meet minimum nutrition standards. While many universities participate in voluntary campus wellness initiatives, only one university–the University of California (UC), Berkeley–has officially adopted a comprehensive, campus-wide nutrition policy, the Food and Beverage Choices (FBC) Policy. Researchers at the UC Nutrition Policy Institute and UC Berkeley collaborated with the FBC policy implementation team to publish a case report in the Journal of Nutrition Education and Behavior, presenting detailed information on the development, establishment, implementation and evaluation of the FBC policy. The report includes discussion of the challenges and barriers encountered during policy implementation and offers valuable insight for other universities seeking to develop and implement their own nutrition policies. The report was developed by Zachary Rickrode-Fernandez of Center for Environmental Health and UC Berkeley, Janice Kao of the UC Nutrition Policy Institute, and Mary Lesser and Kim Guess of UC Berkeley.

  • Nutrition Policy Institute submits comments to EPA on school drinking water safety and lead testing

    The Lead and Copper Rule (LCR)–a U.S. federal regulation under the administration of the Environmental Protection Agency (EPA)–­limits the concentration of lead and copper allowed in utility-provided tap water. The LCR provides requirements for various actions to monitor and reduce lead and copper content of tap water and to inform the public. The EPA recently undertook the first revision of the LCR in 30 years with the Trump administration publishing final revisions on January 15, 2021. However, on January 20, 2021, the Biden administration issued a Regulatory Freeze Pending Review memorandum to ensure any new or pending rules be reviewed by the new presidential appointees or designees and be re-opened for public comment. The EPA posted an extension of the effective date of the revised LCR on April 14 to enable the agency to seek further public input, particularly from communities most at-risk of exposure to lead in drinking water. Nutrition Policy Institute's (NPI) Christina Hecht and Angie Cradock of the Harvard TH Chan School of Public Health submitted one of the over 20,000 public comments providing recommendations for the final revision of the LCR. Hecht and Cradock's comment focused on school drinking water safety, providing recommendations based on their findings from a comprehensive study of states' school drinking water lead testing initiatives and lead test results. Their recommendations included: testing all taps used for human consumption in school and childcare facilities, rather than the subset–5 taps in schools, 2 in child care–required by the earlier proposed revision; a faster timeline for initial testing of all taps; and a lower action level for lead in tap water.
