Daily physical activity supports youth physical and phychosocial health and is also important for obesity prevention. Schools are an important location for physical activity promotion and obesity prevention given youth spend up to half of their waking hours in school. The latest study from Nutrition Policy Institute (NPI) researchers suggests that United States Department of Agriculture (USDA) Supplemental Nutrition Assistance Program Education (SNAP-Ed, and known asCalFresh Healthy Living (CFHL) in California) physical activity interventions at school-sites are associated with slightly lower body mass index (BMI) and greater cardiovascular fitness in students compared to sites that did not receive these interventions. Further, schools with higher intervention levels had students with the highest cardiovascular fitness levels. Interventions included physical activity-related direct education, where students were actively engaged with an educator; indirect education, where students received information or resources related to physical activity; or changes to the school or district's physical activity related policies, systems, and/or environments (PSE). Student-level FitnessGram(R) data from between 2015-2016 was obtained from the California Department of Education for the study. Researchers compared BMI and student cardiovascular fitness levels from over 97,000 fifth and seventh grade students from 904 California public schools that implemented the SNAP-Ed physical activity interventions to over 372,000 fifth and seventh grade students from 3,506 California public schools that did not implement the interventions. These findings are important as the California Department of Public Health's Nutrition Education and Obesity Prevention Branch distributes over $50 million in CFHL funding to local health departments to implement physical activity and nutrition interventions, which primarily occur in the public school setting. Also, California has more public schools than any other US state. The study was published online in the journal Preventive Medicine Reports. The study was conducted by NPI's Hannah Thompson, Sridharshi Hewawitharana, Janice Kao, Carolyn Rider, Evan Talmage, Wendi Gosliner and Gail Woodward-Lopez in collaboration with Lauren Whetstone of the California Department of Public Health. The study was funded by the California Department of Public Health, with funding from the USDA Supplemental Nutrition Assistance Program. The full study is available online.
Behavioral health disorders, such as depression and anxiety, affect a significant number of Americans each year. In 2017 one in eight youths between 12 to 17 years old experienced a major depressive episode compared to one in 14 adults. Approximately one in three people in the US have experienced an anxiety disorder in their lifetimes, with women experiencing anxiety at rates two times that of men. Further, rates of these illness have increased since the coronavirus pandemic came to the US. Poor diet quality has been implicated with the development of depression, anxiety and other psychiatric conditions given the essential role of key dietary nutrients in the body's nervous and hormone systems. Nutrients naturally found in food and beverages--such as tryptophan, vitamin B6, vitamin B12, folate, phenylalanine, tyrosine, histidine, choline, and glutamic acid--are critical for the production of the key neurotransmitters--serotonin, dopamine, and norepinephrine--involved in the regulation of mood, appetite and cognition. Therefore, improving diet quality may contribute to the prevention and treatment of these illnesses.
Nutrition Policy Institute (NPI) researcher Gail Woodward-Lopez contributed to a collaborative narrative review that describes the global burden and features of depression and anxiety and summarizes the latest scientific evidence on diet and nutrition in the prevention and management of these illnesses. The review concludes with a call for nutritional medicine to be incorporated into psychiatric practice to support individuals in achieving a healthy dietary pattern, one rich in fruits, vegetables, whole grains, low-fat dairy, and lean protein foods. It further recommends additional research be conducted to better understand how diet affects behavioral health disorders. The review was published online in the journal Nutrition Reviews on May 24, 2020. The study was conducted in collaboration with Penny Kris-Etherthon and Kristina Petersen of the Pennsylvania State University, Department of Nutritional Sciences; Joseph Hibbeln of the National Institute of Health, National Institute on Alcohol Abuse and Alcoholism; Daniel Hurley of the Mayo Clinic; Valerie Kolick of the US Department of Health and Human Services, Substance Abuse and Mental Health Services Administration; Sevetra Peoples of the George Washington University, Milken Institute School of Public Health; and Nancy Rodriguez of the University of Connecticut, Department of Nutritional Sciences. The study was conducted as a project of the President's Council on Fitness, Sports & Nutrition Science Board, of which NPI's Woodward-Lopez was a member. The study is available online.
Lorrene Ritchie, director and cooperative extension specialist, and Gail Woodward-Lopez, director of research at the UC ANR Nutrition Policy Institute (NPI) were quoted in an August 25, 2020 article in Morning Ag Clips titled "New policies can help provide healthy beverages to children." The article highlights California's Healthy Default Beverage law, California State Senate Bill 1192, which requires that all restaurants in California as of January 6, 2019 offer only healthy beverages -- plain water or unflavored milk -- as the default beverage with kids' meals. The article also highlights research findings from NPI researchers in collaboration with University of Delaware on the impact of the law in California and a similar law in Wilmington, Del. Dr. Ritchie is quoted, "Parents look at menu boards and kids look at menu boards, but it is likely that what the cashier says also influences which drink they choose. In our data collection, we would order a kids' meal and wait for them to offer a drink. But mostly they said, ‘What drink do you want?' instead of ‘Do you want water or milk with that?'”. Woodward-Lopez is quoted, “NPI in partnership with the California Department of Public Health is working with some local health departments to provide training and materials to help restaurants comply with the letter and spirit of the law. Our next step is to measure whether this health department support is effective. The role of default beverage policies in this context is important and not well understood.” Read the full article online.
At fast food and sit-down restaurants across California, kids' meals come with water or milk automatically. At least, that should be the case since state law requires restaurants to offer the healthy beverages by default to reduce the amount of sugary beverages served to children. California Senate Bill 1192, authored by Sen. Bill Monning (D-San Luis Obispo), went into effect in January 2019, but research by the UC ANR Nutrition Policy Institute (NPI) has found that implementation has not been universal. The results, along with results from a similar study in Wilmington, Del., were published in an issue brief Aug. 20 on HealthyEatingResearch.org. Before the law, 10% of menu boards observed by the researchers in California list only the healthy beverages. Data collected after the law went into effect showed 66% of menu boards list the healthy default beverages. NPI researchers also collected data on the proportion of cashiers who verbally offered only healthy beverages with kids' meals when orders were placed. This happened only 5% of the time before the law was enacted, and dropped to 1% after. The law doesn't specify whether the cashier must offer the default beverages, but the spirit of the law suggests they should, as it would likely have a greater impact on the selections that children and parents make. In interviews with NPI researchers, most restaurant managers expressed support for the legislation, but didn't know much about it. The research brief was written by NPI researchers Lorrene Ritchie, Phoebe Harpainter, Marisa Tsai, Gail Woodward-Lopez and Wendi Gosliner in collaboration with lead author Allison Karpyn and Laura Lessard, Jesse Atkins, Kathleen McCallops and Tara Tracy of the University of Delaware. The research was funded by the Robert Wood Johnson Foundation and by the California Department of Public Health with funding from the United States Department of Agriculture.

A recent study by Nutrition Policy Institute (NPI) researchers assessed differences in quick-service, or fast-food, restaurants with and without voluntary healthy default beverage standards for kids' meals. ‘Voluntary standards' are restaurant commitments to offer healthier drinks with kids' meals. Researchers evaluated the beverages shown on kids' meal menu boards, beverages offered by cashiers with kids' meals, and kids meal beverages selected by customers in 111 quick-service restaurants--70 with voluntary standards and 41 without--in SNAP-Ed eligible neighborhoods in 11 California counties. Data was collected by menu board and cashier order observations and customer surveys in December 2018 prior to the January 2019 implementation of a new California law (SB-1192) that requires all restaurants offering a kids' meal make the default beverage offered water, unflavored milk or a nondairy milk alternative and that only these beverages be displayed on kids' meal menus or advertisements.
Results from the study showed that significantly more quick-service restaurants with voluntary healthy default beverage standards for kids' meals offered unflavored milk or water on their menu boards compared to restaurants without voluntary standards. Customers at restaurants with voluntary standards reported purchasing healthier drinks and less soda compared with customers at restaurants without voluntary standards. These results suggest the voluntary healthy default beverage standards were effective at positively influencing restaurant practices and customer behavior. However, not all quick-service restaurants followed their own standards and much room for improvement remains. Additional intervention may be necessary to support full implementation of the standards and to maximize the impact on customer behavior and jurisdictions passing healthy default beverage laws for restaurant kids' meals may need to provide education and outreach alongside enforcement to ensure full implementation. The study was published online on July 22, 2020 in the International Journal of Environmental Research and Public Health by NPI researchers Phoebe Harpainter, Sridharshi Hewawitharana, Danielle Lee, Anna Martin, Wendi Gosliner, Lorrene Ritchie and Gail Woodward-Lopez.
