MyPlate icon clearly shows many Americans how to formulate healthy meals for their families with the proper proportions of fruits and vegetables, protein foods, grains and dairy products. However, UC Cooperative Extension nutrition educators in Central California discovered that the infographic was too abstract for local low-literate families. They embarked on a years-long effort to translate the shapes and colors into a series pictures showing plates filled with healthful, real food.
The concept clicked, so county and campus-based researchers joined together to document the effectiveness of a new curriculum shaped around pictures of properly portioned plates of food to share with nutrition educators around the nation and world. They wrote an article, A Picture is worth a thousand words: Customizing MyPlate for low-literate, low-income families in 4 steps, which was published in the July-August 2015 issue of the Journal of Nutrition Education and Behavior. In 2016, the article was named the “paper of the year” in a category of articles and research programs called “great educational material” (GEM).
In the paper, the researchers shared a four-step process for creating a set of meal photographs that will resonate with families in different communities.
The four steps are:
- Review food patterns and determine meal combinations – This is done by asking clientele what foods they recently fed their families. Once the foods are identified, they can be modified to meet MyPlate recommendations.
- Test meals and take final photographs – Prepare the meals, take photos and test the photos with the target audience.
- Develop and test education messages to accompany photos – Messages should have few words, use family vocabulary and be written for a low-literacy audience.
- Create and test education materials – After the suggested materials are created, they should be tested with the target audience.
The UC Cooperative Extension Expanded Food and Nutrition Education Program (EFNEP) is using the “My Healthy Plate” materials in reaching out to low-literacy and low-income families in California.
The authors of the Journal of Nutrition Education and Behavior paper of the year are Mical Shilts researcher at UC Davis; Margaret Johns, nutrition, family and consumer science advisor in Kern County; Cathi Lamp, emeritus nutrition, family and consumer sciences advisor in Tulare County; Connie Schneider, emeritus Youth, Families and Communities director for UC Agriculture and Natural Resources; and Marilyn Townsend, UC Cooperative Extension nutrition education specialist in the Department of Nutrition at UC Davis.

“I applaud USDA's decisions to increase servings of fruits and vegetables, whole grains, cereals low in sugar, and healthy beverages, including breastfeeding,” said Ritchie, who has devoted her career to the development of interdisciplinary, science-based and culturally relevant solutions to child obesity.
The U.S. Department of Agriculture released new nutrition standards in April for food and beverages served to young children and others in child care settings that participate in the Child and Adult Care Food Program (CACFP). Through CACFP, more than 3.3 million children and 120,000 adults receive nutritious meals and snacks at day care, afterschool centers and emergency shelters. The final rule is intended to better align the nutritional quality of meals and snacks provided under the program with the Dietary Guidelines for Americans.
letter of support to USDA.
At USDA's behest, the Institute of Medicine convened a committee of eminent nutrition researchers to develop science-based recommendations for CACFP meals and snacks that meet the challenge of the Healthy, Hunger-free Kids Act of 2010: to align the CACFP standards with the latest Dietary Guidelines for Americans.
“USDA has taken the IOM's recommendations and translated them into nutrition standards that help address obesity and overweight as well as food insecurity. The new standards are straightforward for childcare sponsors and providers and impose no new, added costs,” said Ritchie, who is also a UC Cooperative Extension nutrition specialist.
This update to CACFP standards is an important step toward ensuring that young children have access to the nutrition they need and develop healthy habits that will contribute to their well-being over the long term, Kevin Concannon, USDA undersecretary, said in announcing the new standards.
“Research indicates that America's obesity problem starts young, with obesity rates in preschoolers more than doubling over the last three decades and one in eight preschoolers classified as obese,” Concannon said. “Since taste preference and eating habits develop early in life, CACFP could play a crucial role in the solution.”
Ritchie, who has conducted studies on the impact of policy on nutrition practices in child care settings, thinks USDA's process for developing the new nutrition standards is effective.
“The new meal patterns demonstrate that the process for regularly updating nutrition standards in the federal food programs, using evidence-based IOM recommendations, is working well,” she said. “The new CACFP standards should make a significant beneficial contribution to the health and development of the nation's young children.”
The NPI director, who has led a push to persuade the government to make water the drink of choice in the dietary guidelines and add an icon for water on the MyPlate food guide, also praised USDA's authorization of reimbursement for the expenses involved in providing bottled water in the rare instances when tap water is not potable.
“UC Nutrition Policy Institute has a special commitment to expanding children's consumption of drinking water,” Ritchie said.
The UC Nutrition Policy Institute's mission is to improve nutrition and reduce obesity, hunger and chronic disease risk in children and their families in diverse settings. NPI provides nutrition policy leadership built from UC Agriculture and Natural Resources' numerous research, and education activities, and works in synergy with research and outreach efforts being conducted throughout the University of California system.
There are several ways to overcome these gardening pitfalls to help ensure you have a successful warm-season vegetable gardening experience.
Plan, plan and stick with your vegetable garden plan!
Planning is a key component to having a successful vegetable garden, but is frequently forgotten or overlooked. Planning includes selecting an appropriate location for your garden, choosing the correct varieties of crops for your space and developing a garden plan for what you would like to grow.
When selecting a location it is important that the site receives at least eight hours of full sun, is close to a water source (hose, irrigation or hand-watering) and has good soil for optimal growth. Once you have an appropriate location picked out, creating a garden plan will help contribute to your growing success.
Too often the overall size of the garden area and the size of mature plants is not considered. Keep in mind a young plant can become established and quickly overtake a small garden lot, challenging or dominating other plants for resources.
“A well planned garden can provide fresh or preserved vegetables for use year-round. The plan should contain crops and amounts to be planted, dates of planting and estimated harvest, planting location for each crop, specific spacing between rows, and trellising or support required,” according to the California Master Gardener Handbook (see Figure 13.1 on Page 342).
Invest a little time and develop a detailed plan to help guide you on where, which type and how many plants you will need for your space. Your vegetable garden plan will keep you focused while shopping at your local nursery and prevent impulse buys of tempting transplants!
Caring for your vegetable garden
Irrigation is a key component in a successful vegetable garden. Consistent, deep and sufficient watering will produce better tasting and superior quality fruits and vegetables, especially during the hot summer months when it is easy for the soil to quickly dry out.
“As a rule” the handbook says on Page 349, “it will be necessary to irrigate your vegetable garden one to three times a week in summer ... The frequency will be determined by the depth of crop roots, soil texture, and weather conditions. Wet the soil to just beyond the bottom of the root system at each watering.”
Even in a time of drought, vegetable crops require the soil to remain moist during their crop cycle. Poor irrigation practices and infrequent watering will produce smaller yields and poor quality fruits and vegetables.
Weed prevention and maintenance is an important piece in caring for your vegetable garden. Without monitoring and controlling weeds, your crops could quickly become overrun by these pesky unwanted plants. Apply a three- to four-inch layer of organic mulch to discourage the growth of weeds. Prevent weeds by hand-weeding before they become established and go to seed. The UC Integrated Pest Management (IPM) Program has detailed information available on its website about sustainable weed management in the home landscape.
Harvesting (and enjoying) your crop
Produce Fact Sheets to help guide you on when to best harvest your crops.
“To get the most from your vegetables, harvest them when they are at the best stage for eating and store them under conditions that will keep them as close to garden-fresh as possible,” recommends The California Garden Web. “Vegetables will be crisper and cooler when harvested in the early morning.” (cagardenweb.ucanr.edu)
Once harvested don't forget to enjoy the fruits (and veggies) of your labor. Few experiences can compare with the gratification of eating homegrown fruits and vegetables for the first-time!

UC Cooperative Extension in Riverside County is bringing together students, agencies, nutrition educators and gardening experts to work alongside families to grow produce in garden plots at a community facility.
“Many people don't know how to get started gardening,” said Chutima Ganthavorn, the nutrition, family and consumer sciences advisor for UCCE and manager of its local UC CalFresh Nutrition Education Program. “Gardening takes space, water, resources like seeds and transplants, plus guidance and support. Our group is going the extra mile in Riverside County to help people grow and eat healthy food.”
This year, the local coalition received $10,000 in support from the Kaiser Permanente Heal Zone project to expand a vegetable garden at the Community Settlement Association (CSA), a center where community members gather for UC CalFresh nutrition classes, weekly food distributions and other services.
“A few years ago, the garden plots at the Community Settlement Association were neglected and weedy, while families struggled to get healthy food,” Ganthavorn said. “UC CalFresh teamed up with UCCE Master Gardeners and CSA staff to turn them into bountiful and beautiful edible gardens. Now our coalition is growing to include UCR Community Garden and Heal Zone members, including folks from City of Riverside Parks and Rec and Riverside Community Health Foundation.”
In 2014, UC Master Gardener volunteers, nutrition educators and members of the community planted vegetables in five existing garden boxes at Community Settlement Association, 4366 Bermuda Ave. in Riverside.
For planting day, neighborhood families – many who had taken part in UC CalFresh nutrition classes at the CSA – tilled the ground and planted seeds and transplants to grow tomatoes, bell peppers, summer squash, lettuce, green beans and Swiss chard.
“We're fixing up a garden for the children,” said Gonzalo Rodriguez, who joined planting day with his family. “We're planting chili and tomato transplants and seeds, food that will provide vegetables and give the children the joy of caring for the plants.”
In 2015, UC CalFresh arranged a $500 grant from Wood Streets Green Team, a local group that promotes sustainable living, to purchase fruit trees. Master Gardeners led volunteers to plant blackberry bushes, and peach, pluot, nectarine, plum, fuji apple and mini mandarin trees. They also planted quince, pomegranate, lemon and lime trees donated by a Master Gardener.
With the Heal Zone funds and support from UC Riverside student Claudia Villegas, the recipient of a Global Food Initiative Fellowship from the UC Office of the President, an extended garden began to take shape.
Villegas recruited students from Sigma Alpha Epsilon and Phi Chi Theta fraternities to transform a lawn at the community center with cinderblock raised beds. She is coordinating training sessions and encouraging local families to visit.
“I want the community to feel comfortable coming to the garden,” said Villegas, a senior psychology major. “I want them to just come in and hang out and interact and talk about gardening problems.”
The raised-bed plots have been assigned to families in the community.
“They feel ownership and maintain the gardens,” Ganthavorn said. “They can keep the produce they grow, and any extra produce goes to the weekly food distribution program at CSA.”
A gardening club now meets from 9 to 10 a.m. the first Thursday of each month at the community garden. UC Cooperative Extension coordinates gardening workshops with UC Master Gardener volunteers and nutrition and cooking sessions with UC CalFresh educators.
A 4-H club for children in the community is also being developed at the CSA site by Claudia Diaz Carrasco, UCCE 4-H Youth Development advisor. The purpose of 4-H clubs is to help diverse young people discover and develop their potential and grow into competent, contributing, and caring citizens.
“We believe that CSA children will benefit a lot by participating in 4-H learn-by-doing activities within the club,” Diaz said. 4-H clubs usually meet in the evenings or on weekends and offer self-chosen multiple learning experiences.
For many years, a key international strategy to ending hunger has been to grow more food: push for higher yields, develop ways for farmers to intensify their farming, focus on technologies that drive both. But that focus may be shifting towards another strategy that better accounts for the environment and human well-being – agroecology.
Barbara Gemill-Herren, a retired officer from the Food and Agriculture Organization of the United Nations, spoke recently at UC Davis of the ongoing process at the United Nations to determine an international strategy for agricultural development.
For many, a new paradigm needs to strike a balance between supporting small-scale farmers, supporting healthy ecosystems, and bringing in the technology that can help meet changing challenges for growers.
Agroecology has recently entered the vocabulary at the UN as a potential unifying principle for agricultural development.
As its name suggests, agroecology studies the ecology of the entire food system, focusing on environmental, economic and social dimensions and how they interact with one another.
Beyond that definition, the term is used and understood differently by different groups. For some, agroecology is a scientific discipline, for some it represents a way for farms to be managed. For others, it is a social movement that brings local and indigenous knowledge to the center of agricultural development.
At the United Nations meetings on agroecology, each of these interpretations of agroecology have been on the table for discussion — how they can be used to improve international agricultural development will be revealed in global conversations in the years to come.
Agroecology endowment at UC Davis secures research opportunities
Here at home, agroecology is on the upswing as well. Funding for a $1 million endowment in agroecology was recently secured at UC Davis to help fund the research, education, and outreach conducted by an agroecology faculty member. Collaborating with UC Cooperative Extension farm advisors from UC Agriculture and Natural Resources will be a key way for future work to connect with growers.
Endowments offer reliable funding every year that allow faculty to plan longer term research. For research like agroecology that looks at how agricultural systems function, that flexibility is important, if not essential.
Tom Tomich, director of the Agricultural Sustainability Institute, which helped raise funds for the endowment, says, “The endowment represents at a broad spectrum of philanthropists and shows that scientific approaches to agroecological systems science is appreciated by our stakeholders in California. It's a form of legitimization of systems science applied to agriculture.”
Opportunities for collaboration between researchers and farmers
Below are some thoughts from Gaudin on how she approaches her work and how she sees this agroecology endowment impacting research and education at UC Davis.
How do you define agroecology?
There are different definitions of agroecology for different people. Mostly I see it as research to understand dynamics of ecological processes and to apply ecology to agricultural systems design. Agroecology merges the food security and production goals of agriculture with resource use efficiency goals and environmental goals in agriculture. For many people, agroecology is a social movement to make systems socially just. While my focus is largely on biological processes, it's also about learning from small-scale farmers who have been successful in their management practices to see how we can translate those successes to other contexts. And that is very social in nature.
At what scale do you research?
Usually we tend to work at the field scale, looking at cropping systems and the landscapes that surround them. Looking at the field, we can see how the long term management of a farm has affected the soil and its functioning as well as productivity and provision of multiple other ecosystem services. Looking at the surrounding landscape, we can understand what the natural environment has provided to the farm system, and what the farm system provides back to the natural environment. Sometimes we look a meter out, sometimes a kilometer out.
But beyond just the space we look at, we're really looking at time. Nature takes time. When you look at the field, it's an observation of what has been going on there for a very long time.
How does agroecology research work with farmers?
Working with farmers helps give research the long-term lens and management gradients we need to understand these agricultural systems, and gives us a landscape lens that many research fields can't provide. It also helps relate our research to production constraints that farmers have.
There is also tremendous innovation in what farmers are coming up with. They have a specific problem and they usually have tried specific solutions. They test things out, they monitor their fields and see results, but maybe don't understand fully the underlying mechanism and potential impact on the environment. We try to get to the why; we try to connect the dots to enable scaling up and better understanding of the ecological processes regulating resource use efficiency.
We're also looking a lot at resilience to stresses. And we find more and more interest in this because resources are not plentiful anymore and we now have to produce more with less. So how do we build resilience to the multiple stresses that come along? Are there ways that the management of a farm can impact productivity when a stress like drought occurs?
We have a lot to learn from small growers and a lot to learn from growers who have constrained resources about what they have been implementing and experimenting with. How can we transfer those practices to different environments? How can we scale them up?
How can we make it work in large-scale agriculture? There's a huge opportunity there. I want to see agroecological approaches to management implemented all over the Midwest, all over the Central Valley. I think agroecology is compatible with large-scale agriculture and critically needed.
How do you approach research questions?
I start with the problems a farmer didn't have. One project started with a tomato farmer who didn't have the same insect problem that surrounding farms had. So we ask, what is he doing that created this insect resistance, and how can that be used by other farmers? We met with several different farmers to discuss the issue, and wrote a grant to investigate specific hypothesis across a management gradient.
We're now working with five different growers and using Russell Ranch, our long-term agricultural research facility, as a benchmark.
I think conversation with farmers and their advisors is critical to develop relevant research questions and alternatives which have conservation of natural resources, biodiversity and provision of ecosystem services as a basis for improvement. It is also important to keep a positive feedback loop and bring results back to the community to foster farmer-to-farmer knowledge transfer.
What excites you about this new investment in agroecology?
The context of agriculture is changing and we now have a tremendous opportunity to promote agroecology as a viable and necessary strategy to build the sustainability and resilience of our agriculture. Farmers are seeking solutions, they are aware and interested. With climate change and depleted resources becoming more of a reality, growers are interested in putting soil improvement and ecological principles back into their management framework. And I think we ultimately care about the same things, we just need to find common ground and start speaking the same language. To do it we have to be open minded, both on the researcher and farmer side.
Investment in agroecology will help us reach this objective and gives us an opportunity to think outside of the box. This gives an opportunity to be creative, cope with some of the pitfalls of science funding and take a participatory approach to interdisciplinary research to design holistic solutions that better use nature for a sustainable agriculture./h3>/h3>/h3>/h3>/h3>/h2>/h2>
