  • NPI researcher Kassandra Bacon to present at the 2024 Child and Adult Care Food Program conference

    Oct 3, 2024

    Nutrition Policy Institute's Kassandra Bacon will present with CACFP Roundtable's Samantha Kay-Daleiden Marshall at the 2024 Annual CACFP Conference at Universal Studios, CA. The conference focuses on the growth of the Child and Adult Care Food Program, commonly known as CACFP. On October 8, 2:30pm-3:30pm PT, a workshop, “Impacts of COVID-19 Changes to Meal and Snack Reimbursements on Family Child Care Home Providers, Children and Families” will highlight research by NPI's Kassandra Bacon, Danielle Lee, Celeste Felix, Lorrene Ritchie, UC Berkeley's Susana Matias, and CACFP Roundtable's Samantha Kay-Daleiden Marshall and Elyse Homel Vitale. Their research examines the effects of both higher CACFP reimbursement rates for family child care homes during COVID-19 and the return to lower rates post-COVID-19. They will share results from surveys and interviews with California-based providers and sponsors on the nutritional quality of meals and snacks served in child care homes, and food security for child care providers and families. The workshop will engage CACFP stakeholders to develop proposed policy solutions based on study findings.


  • Recent study reveals increased CACFP reimbursements during COVID-19 boosted meal quality in California family child care homes

    Oct 1, 2024

    The federal Child and Adult Care Food Program, commonly known as CACFP, provides tiered reimbursements to family childcare homes to ensure children in low-income communities have access to healthy meals. To address heightened food insecurity during the COVID-19 pandemic, tiers were eliminated and all participating family childcare home providers received increased CACFP reimbursement rates. Nutrition Policy Institute researchers examined the perceived impacts of increased reimbursements on CACFP participation and challenges anticipated with the reinstatement of tiered rates after the pandemic from surveys completed by 518 California providers. Results showed that the temporary higher reimbursement rates lowered out-of-pocket food costs, were more adequate than rates prior to COVID-19, and supported greater perceived variety, quality, and healthfulness of foods served, especially for tier 2 providers who previously received the lowest reimbursement. Removal of the tiered reimbursements may help improve child nutrition and address the rise of nutrition-related chronic conditions. The study was published in the Nutrients journal by NPI researchers Lorrene Ritchie, Kassandra Bacon, Celeste Felix, and Danielle Lee, Samantha Marshall and Elyse Homel Vitale with the CACFP Roundtable, and Susana Matias with the Department of Nutritional Sciences and Toxicology at the University of California, Berkeley.


  • Arizona survey of food service directors finds the transition away from free school meals posed challenges for students, parents, and administration

    Sep 26, 2024

    A 2023 Arizona survey of food service directors and school nutrition staff identified the effects of the move away from free school meals for all students in the 2022-2023 academic year. While Arizona students no longer were provided free school meals for all, a statewide policy that eliminated co-pays for reduced-price lunch took effect in January 2023, expanding the population of students able to receive meals without charge. The survey respondents represented almost one-third of Arizona school districts with most districts having at least 40% of students eligible for free or reduced-price lunch. That academic year, 71% of schools reported experiencing a decline in school meal participation. Respondents perceived that inadequate meal variety, taste or portion sizes, as well as stigma around free and reduced-price lunch contributed to the student participation decline. Respondents also reported perceiving that  students prefer meals from home or skipping meals potentially due to high cost. Food service professionals felt that parents were confused about changing meal costs and the burden of an additional application process to qualify for free or reduced-price lunch. More than half of respondents reported an increase in paperwork for administration and staffing challenges. Factors that helped schools during this time included federal Supply Chain Assistance funds, state and federal funding for school meals, and a supportive district administration.


  • NPI welcomes UC Irvine graduate student Christian Black as UC Bonnie Reiss Climate Action Sustainable Agriculture and Food Fellow

    Sep 6, 2024

    Christian Black joined the Nutrition Policy Institute at the University of California in September 2024 as our 2024-2025 UC Bonnie Reiss Climate Action Fellowship, Sustainable Agriculture and Food Fellow. Black is a graduate student pursuing a Master's in Public Health with a concentration on Community Health at UC Irvine Joe C. Wen School of Population & Public Health, where he utilizes salivary biomarkers and wearable devices to study the relationship between harsh prison environments and health longevity. As an NPI fellow, Black will support efforts to improve food and nutrition security among currently and formerly incarcerated individuals in California. This 10-month fellowship is part of the 2024-2025 UC Bonnie Reiss Climate Action Fellowship Program, formerly known as the UC Global Food Initiative, which supports the UC's climate goals by reducing greenhouse gas emissions and establishing climate programs and policies centered on equity, sustainability, and resiliency. In addition to working with the NPI Farm to Corrections project team, Black will participate in UC systemwide activities. 


  • Article in EdSource discusses the “Recess for All” law and the benefits of physical activity at California schools

    Sep 4, 2024

    An article in EdSource by Hannah Thompson of the Nutrition Policy Institute and Rebecca London of the University of California Santa Cruz discussed the impacts of the “Recess for All” law in California schools. The law requires at least 30 minutes of recess in elementary schools and bans taking away recess as punishment. Research in education and child development has found that recess benefits behavioral, mental, and physical health in students. Surveys of students have found that recess is a popular subject statewide. Recess also helped students recover from social isolation during the COVID-19 pandemic. It can help students develop interpersonal skills and later focus in the classroom and improve learning. The “Recess for All” law has helped create equity among schools, as students of color and in low-income areas have historically had less recess time. However, the benefits of recess have been underestimated with the rise in standardized testing and decrease in recess and arts during the No Child Left Behind era. Hopefully, with the support of parents and students, the “Recess for All” law can be implemented equally throughout California elementary schools.


  • Article in The Daily Californian highlights Berkeley’s unprecedented soda tax, and its potential for indefinite renewal

    Aug 27, 2024

    A 2024 article by Matthew Yoshimoto of The Daily Californian discussed Berkeley's 2014 soda tax, and its presence on the ballot in November 2024. Since its implementation, the soda tax, a 1-cent-per-ounce excise tax on sugar-sweetened beverages, has had drastic impacts on community health. By 2017, consumption of sugar-sweetened beverages decreased by over 50% and water consumption increased by almost 30%. The revenue has funded efforts to improve the nutrition environment in the low-income and minority communities hardest hit by the sugary drinks. NPI's Ken Hecht highlighted that health in Black and Latine communities has especially benefited from the soda tax's direct and indirect effects. The soda tax has also helped in the efforts to combat childhood obesity. According to a study by Kaiser Permanente, cities where the tax is implemented did not show an increase in childhood obesity rates while rates are increasing elsewhere. Berkeley's change has had a positive ripple effect, with cities including Oakland and San Francisco following with their own taxes on sugar-sweetened beverages. Though the soda tax has had overwhelming support from voters, due to push back from soda companies there are new legislative barriers concerning the tax. While a tax increase is currently not an option for Berkeley, there is hope that in November 2024, voters will consider the positive effects of the soda tax and support its indefinite renewal.


  • Receive free milk for one year and up to $275 by participating in a study on milk consumption for toddlers

    Aug 14, 2024

    With childhood obesity on the rise, research in early life dietary habits are essential to promoting long-term health in children. The current recommendation is for children to drink whole milk from ages 1-2 years, then drink low-fat 1% or non-fat 0% milk. However, there is limited research to support this recommendation. Milk Type in Toddlers—also known as Milk-TOT—is a study being conducted by the Nutrition Policy Institute in partnership with Stanford University and funded by the National Institute of Health. In this randomized control trial, toddlers ages 23-30 months, in the San Francisco Bay Area, will receive whole or low-fat 1% milk for one year through grocery delivery. Their height, weight, waist circumference, diet, and other health markers will be measured throughout the study. Parents will also receive nutrition guidance from a registered dietitian. This study aims to reduce childhood obesity by improving nutrition recommendations and creating long-term healthy eating habits. If your child is healthy and between the ages of 23-30 months they may be eligible for participation. To determine eligibility please fill out this survey. For more information or questions email milktotstsudy@ucanr.edu or call 510-987-9023.
