Cooperative Extension researcher: Nutrition course a boon for UC Berkeley students
College students across the nation are struggling to meet their basic food needs. Within the University of California system of 280,000 students, 38% of undergraduate students and 20% of graduate students report food insecurity.
As part of the UC Global Food Initiative, in 2015 the Nutrition Policy Institute (a UC Agriculture and Natural Resources statewide research center) identified student food insecurity as a UC systemwide problem, prompting the UC Regents and campuses to collectively address the issue.
All 10 UC campuses now have on-site basic needs centers, providing food, emergency housing and support services. The UC system and campus working groups recognize that meeting basic needs, such as food, is a multidimensional challenge.
In response to the 2022 White House Conference on Hunger, Nutrition, and Health, which called for national efforts to reduce diet-related disease and food insecurity, UC renewed their commitment to cut the proportion of students facing food insecurity in half by 2030. Campuses will partner with local counties to maximize enrollment in the Supplemental Nutrition Assistance Program (also known as CalFresh in California), provide food for students who do not qualify for CalFresh, and allocate campus food resources to historically underserved student populations.
NPI's collaborative researchers continue to monitor the impact of these efforts, in addition to other interventions, such as supporting students in building basic culinary skills, to improve food security. One multipronged approach to address food insecurity at UC Berkeley is a 14-week course on Personal Food Security and Wellness with a Teaching Kitchen laboratory component.
Sarah Minkow, who teaches the Personal Food Security and Wellness course at UC Berkeley, shared that students learn about nutrition and gain culinary skills through the Cal Teaching Kitchen.
The curriculum is designed with consideration for the time, cost and convenience of healthy eating. Discussions include food safety, calculating nutrient needs, mindful eating and reading nutrition labels. The Teaching Kitchen laboratory brings the lessons to life through knife skills, “no-cook” cooking, microwave cooking and sheet pan meals.
Minkow enthusiastically highlighted her students' “overwhelmingly positive [response to the] lecture and lab,” suggesting the benefits of an interactive learning environment to garner student engagement.
“Students often give feedback that they wish this was a required course for all UC Berkeley students,” said Minkow. She noted one barrier to reaching more students: capacity of the Teaching Kitchen space.
Susana Matias, a Cooperative Extension specialist at the UC Berkeley Department of Nutritional Sciences and Toxicology and collaborative researcher with the NPI, evaluated the impact of the Personal Food Security and Wellness course at UC Berkeley.
Matias reported that increasing food literacy and culinary skills among students has shown to increase intake of fruits and vegetables, and frequency of cooking, and reduce the number of skipped meals. Her study on the impact of the 14-week nutrition course also found a significant decrease in student food insecurity.
Across the UC System, students are benefiting from their campus Teaching Kitchens, including UC Berkeley, UC Davis, UCLA and UC Riverside. Other campuses such as UC San Diego, UC San Francisco, UC Santa Cruz and UC Santa Barbara offer basic student cooking classes as well.
Katherine Lanca, UC Global Food Initiative fellow working with NPI, attended the 2022 Teaching Kitchen Research Conference as part of her fellowship to learn about the latest research on teaching kitchens supporting equitable health outcomes.
The conference was hosted at UCLA by Harvard T.H. Chan School of Public Health Department of Nutrition in association with the Teaching Kitchen Collaborative. Teaching kitchens are a promising approach to supporting food security and cultivating lifelong habits, especially among a college student population./h3>
A U.S. federal government shutdown can represent a minor inconvenience, a delay in paychecks, or – for people living in some of the most difficult circumstances – an extended period of hunger and anxiety.
A study published recently in the journal Nutrients provides a unique glimpse into the shutdown experiences of participants in CalFresh – California's name for the federally funded Supplemental Nutrition Assistance Program (formerly known as food stamps). Currently, about 42 million people participate in SNAP across the U.S.
In focus groups conducted in 2019 with 26 low-income CalFresh participants from four diverse California counties, participants shared how the 2018-19 federal government shutdown affected their SNAP benefits, their perception of the program and their faith in government.
One of the immediate effects of the 2018-19 shutdown was that February CalFresh benefits were distributed in January. And while that meant program participants saw extra benefits that month, they then had to wait 40 to 44 days until the March issuance – much longer than the usual 28 to 31 day cycle.
“What we saw with this study is that this extended lag in benefit receipt from January to March was devastating,” said Wendi Gosliner, senior researcher and policy advisor at the Nutrition Policy Institute of UC Agriculture and Natural Resources, and an author of the study funded by UC ANR.
She recalled one participant who, despite having a gastrointestinal issue that requires a special diet, had to eat canned food from the food bank that made her sick – rather than go hungry while waiting for her March benefits. Others described cascading financial challenges after using rent money for food in February, or going into debt to pay for food and getting behind on other expenses.
The study also chronicles the experiences of a woman who was anguished to hear the suffering of her daughter, also a CalFresh participant: “She called me several times crying, ‘Ma, I don't – we don't have enough food. What am I going to do…? You know, I can't afford to this and this and this.' And I can't help her.”
For individuals grappling with food insecurity, the stress of feeding their families was compounded by the uncertainties of the government shutdown. And while many participants exercised their agency and resourcefulness in coping with the situation, they also felt a degree of powerlessness amid the “confusion and craziness,” as one person put it.
“No one knew how long that shutdown was going to last; no one knew if the March benefits were going to be paid,” Gosliner said. “And as we learned, there were all kinds of stories circulating out there about what was going on with the uncertainty – a lot of people didn't have the information about what was actually happening.”
Some participants, seeing the “double benefit” in January 2019, thought that it was the last-ever distribution and that SNAP was ending. Others described being unable to get in touch with the CalFresh agency to get their questions answered about the benefits. Most participants had not heard about the disrupted benefit schedule before receiving the benefits. As a result, many people in the focus groups shared that their overall faith in government had been shaken.
Improving customer service, boosting benefit levels and adjusting eligibility and benefit formulas to reflect high cost-of-living and expenses related to working were three recommendations that came from the focus group participants.
A fourth recommendation tackles the shutdown issue head-on: Don't let it happen again.
“Congress should do absolutely everything in their power to be sure that the program operates on the usual time schedule – even if the government is shut down,” Gosliner said.
In the context of the global pandemic, when financial and social inequities and physical and mental health disparities have been laid bare, ensuring access to healthful food is even more important. And with studies showing that hospitalizations increase with longer lags between SNAP distributions, Gosliner said the “absolute last thing” the overburdened health system needs is more people in emergency departments seeking acute care.
“It's the worst time to be having people who need money to feed their families face additional insecurity,” she said. “It's critically important that Congress acts to be sure that there is not any disruption in benefits.”
The authors of the study, “Participants' Experiences of the 2018–2019 Government Shutdown and Subsequent Supplemental Nutrition Assistance Program (SNAP) Benefit Disruption Can Inform Future Policy,” are Wendi Gosliner, Wei-Ting Chen, Cathryn Johnson, Elsa Michelle Esparza, Natalie Price, Ken Hecht and Lorrene Ritchie.

Drinking water safety, especially for children, has become an issue of heightened concern since the water crisis in Flint, Michigan, in 2014.
The National Drinking Water Alliance map has recently been updated to add over 235 new points linking to news reports of tap water contamination, with nearly half of the incidents emerging since 2019.
“We created the map to help community members, advocates and decision-makers visualize the tap water contamination landscape, particularly for incidents of lead that exceed state action levels,” said Christina Hecht, UC Nutrition Policy Institute senior policy advisor and National Drinking Water Alliance coordinator.
Residents can zoom in on their state to check for contamination incidents that were reported in the news. Red pins indicate lead contamination in schools and parks. Clicking on a pin on the map produces a pop-up box containing the name of the town, date and link to the news story.
“Although most tap water is safe for drinking, the number of dots on the map show that there are times and places where tap water is not safe,” Hecht said. “The only way to know if tap water has elevated lead is by testing through an accredited lab.”
The interactive map was created by the Nutrition Policy Institute and Informatics and Geographic Information System at the University of California Agriculture and Natural Resources. The map only includes tap water contamination with lead and contaminants regulated by the U.S. Environmental Protection Agency. For example, reports of perfluoroalkyl substances, or PFAS, contaminating drinking water are not included because PFAS are not regulated by the EPA.
Although a few states now maintain some type of online database of results from school or childcare tests for lead in tap water, to date, there is no national database of lead exceedances in school or childcare drinking water.
The National Drinking Water Alliance map includes information on state policies and programs to test for lead in school drinking water. Almost one-third of U.S. states have enacted legislation providing policy to test for lead in drinking water in schools and, in some cases, in child-care centers. California tests for lead in drinking water at all public K-12 schools and posts the results online. Policies for mandatory testing have recently passed in Oregon and Vermont. New legislation has been proposed in Wisconsin, Iowa, Nebraska and Connecticut. Voluntary programs are now present in every state, funded by nationwide federal grants supporting testing in child-care facilities and schools.
More information on each state's actions can be found on the interactive map at www.drinkingwateralliance.org/new-map, which was updated by Nutrition Policy Institute intern Laurel Denyer, a recent UC Davis graduate.

University leaders, faculty and students from across the U.S. and around the world are working together to tackle a complex set of challenges that prevent millions of people from getting enough of the right foods. In March 2021, UC Davis, the UC Global Food Initiative and the UC Agriculture and Natural Resources Nutrition Policy Institute, in partnership with the Hunger Solutions Institute at Auburn University, hosted a summit for members of Universities Fighting World Hunger, where more than 500 attendees from 22 countries sought solutions to the tragedy of world hunger, food insecurity and malnutrition that results in chronic diseases and obesity.
The 16th annual summit, held virtually for the second time, introduced a new way to address hunger by focusing on its connections to global climate change and the catastrophic COVID-19 pandemic.
Opening keynote speaker Bill Dietz, director of the Redstone Global Center for Prevention and Wellness at George Washington University, called the multiple threats to human well-being a “syndemic” driven by political power, capitalism, social norms and structural racism.
He suggested triple-duty solutions to the syndemic. For example, for U.S. populations, increasing plant-based foods and reducing beef consumption leads to (1) healthier diets that reduce obesity, diabetes and cancer; (2) improves nutritional quality and food security; and (3) lowers greenhouse gas emissions from agriculture and cattle production.
“I don't mean to say we eliminate beef,” Dietz said. “Beef can be healthy if grass fed and contains micronutrients. We need to reduce it. I don't pretend that's an easy lift. There is resistance at the highest levels of government. But we need to generate the political will to turn that around.”
Dietz recommended the development of local and regional food systems for food resilience, health, equity and environmental sustainability. Regional systems are more agile and not devoted to monoculture, such as that found in the U.S. Midwest where great swaths of land are managed exclusively for corn production.
“The question is not what we need to do, but how to do it,” Dietz said. “We need to act now. We need to build political will. We need to hold leaders accountable.”
A new Green Revolution
On the world stage, increasing access to food must address poverty, inequality, wars and politics, said Rattan Lal, distinguished professor of soil science at Ohio State University.
The projections that the earth will have 2 billion more residents by 2050 means there's a need for a new “Green Revolution,” Lal said. In the 1950s, fears that food production was lagging behind population growth were rampant. The fears were not realized due to the mid-century Green Revolution, in which research and technology boosted agricultural production worldwide with advances in variety selection, irrigation, synthetic fertilizers and pesticides. Yields rose exponentially.
“This miracle saved hundreds of millions from starvation,” Lal said. “Despite all that progress, there is still hunger.”
To meet food demand anticipated in 2050, the new Green Revolution must be different.
“Rather than input based, it must be natural resources based,” Lal said. “The strategy is to produce more food from less land, less water, less fertilizers and less energy.”
Managing agricultural land with regenerative principles – such as maintaining year-round soil cover, eliminating tillage and applying integrated nutrient management – leads to healthy, sustainable and productive soils that lock up carbon and minimize greenhouse gas emissions to the atmosphere.
“Something I hope to see protected in the new Farm Bill – the rights of soil,” Lal said. “Soil is a living entity. It has rights. We have a Clean Air Act, a Clean Water Act. It is time for a Healthy Soil Act. I hope it will be in 2022 or 2023. That involves policy translating science to action.”
The benefits of soil health are research-proven, but not yet widely implemented on farmland around the world, an example of a dichotomy shared by summit keynote speaker Jeffrey Sachs, an economist with the Center for Sustainable Development. He quoted the well-known observation of science fiction writer William Gibson, “The future is already here – it's just not evenly distributed.”
“There are solutions. I call them pathways. They are not gimmicks,” Sachs said. “Our work is to build the public understanding and awareness of the importance of these pathways.”
Sachs encouraged summit attendees to advocate locally and at the state and federal levels to promote new food systems approaches.
“Write blogs, op-eds and suggestions. What can corporations commit to? What should governments commit to? What can the food industry commit to?” Sachs said. “A lot of agricultural policies promoted by large commercial interests neglect environmental objectives. What we need is a one-world approach to move beyond the narrow view of a powerful corporate lobby and move to ecosystem sustainability in agriculture, carbon storage, healthful diets and a culture of appreciation of agriculture and healthful food.”
A role for land grant universities
Lorrene Ritchie, director of UC's Nutrition Policy Institute, said she believes UC Agriculture and Natural Resources and other land grant institutions can help direct humanity along a pathway of human and planet health.
“We have nutrition programs, dairy and beef research, irrigation, pest control, production, and natural resources expertise, and are well positioned to work together,” Ritchie said. “As a nutrition researcher, I can bring expertise on human dietary needs, while others can identify the crops that are most environmentally sustainable in different ecosystems. How we can get the best nutrition with the smallest environmental impact is the key question to address.”
Consumers can also help protect the planet's health with information to make educated decisions about their food choices.
“I would like to see food labeling not only for nutrition, but also on the product's sustainability,” she said.
Impacts from food on the planet's health involve production, water use, transportation, packaging and other factors.
“It kind of makes you dizzy to think about balancing impacts to human health and planet health. At UC ANR, we have the expertise and we can contribute to making progress in California and beyond in that regard. Complex problems will require multiple solutions – the time to act is now,” Ritchie said.
Schools across the nation are removing chocolate milk from their meal programs to reduce students' intake of added sugar.
Some people are concerned the new policy will lead to a decrease in students' milk consumption and, specifically, reduce the essential nutrients that milk provides, such as calcium, protein and vitamin D. They also fear the policy could lead to an increase in milk waste. However, results from a study conducted by UC Nutrition Policy Institute may alleviate these concerns.
While the study found that the number of students who selected milk during lunch dropped by about 14% in the year the chocolate milk was removed, there was a no significant difference in the proportion of milk wasted before and after policy implementation. Milk consumption declined by about 1 ounce per student post policy implementation, resulting in a small but statistically insignificant decrease in the average amount of calcium, protein, or vitamin D consumed from milk.
The chocolate milk removal policy did result in a significant reduction in added sugar consumption from milk, by an average of 3.1 grams per student. These results suggest that a school meal chocolate milk removal policy may reduce middle and high school students' added sugar intake without compromising intake of essential nutrients nor increasing milk waste.
The study was conducted by NPI affiliated researchers Hannah Thompson and Esther Park from the UC Berkeley School of Public Health in collaboration with NPI researchers Lorrene Ritchie and Wendi Gosliner, and Kristine Madsen from the Berkeley Food Institute and UC Berkeley School of Public Health. The study was published online on August 27, 2020 in the journal Preventing Chronic Disease. The full study is available online.
