Not so for those enrolled in the foods and nutrition program in UC Agriculture and Natural Resources' (UC ANR) 4-H Youth Development Program. Youths as young as five learn how to prepare healthy nutritious food.
And yes, they learn how to make desserts, such as special treats for their family and friends at Halloween.
Former Solano County 4-H All-Star Ambassador Julianna Payne was so interested in the foods and nutrition project offered by the Sherwood Forest 4-H Club, Vallejo, she plans a culinary career.
"That's where I found my love of cooking and most especially, baking," said Payne, 19, who just completed her 14th year in 4-H, including 10 years in foods and nutrition.
4-H is administered by UC ANR Cooperative Extension offices in every California county. The program focuses on leadership and life skills.
"I believe that one of the most important life skills a person needs is knowing how to cook for themselves," Julianna said.
Payne, a 2014 high school graduate, is in her second year at Solano Community College, Fairfield. In the spring, she plans to attend an area culinary school to earn her associate degree in baking and pastry.
"During my 10 years in the food and nutrition project, I made so many things I could not even begin to count," she recalled. "I have made savory things like tamales, empanadas, raviolis, and chilis and I have made sweet things like, peppermint bark, pumpkin scones, toffees, and chocolate orange cupcakes."
Julianna, who joined 4-H at age 5, went on to serve as president of her club for three years. Her experience, enthusiasm and commitment to 4-H led to her being selected for the county's highest 4-H honor: Solano County 4-H All-Star Ambassador.
Her mother, Sharon Payne, is a former community leader of the Sherwood Forest 4-H Club and a past president of the Solano County 4-H Leaders' Council.
“4-H is a fantastic youth development organization that teaches youth life skills, leadership and citizenship,” said Sharon Payne, a 13-year 4-H volunteer. “Within their projects, youth can learn about whatever topic that interests them, from foods to computers or animals to robotics. Project work stimulates interests and skills and can introduce youth to careers they may not have otherwise considered.”
Said Valerie Williams, Solano County 4-H Program representative: “The 4-H Youth Development Program has a long history of promoting healthy living among youth and their families. Reconnecting youth to a healthy food system and teaching them how to grow and prepare fresh food is the focus of many 4-H healthy living programs. 4-H adult volunteer leaders provide mentoring to 4-H members, which plays a vital role in helping them select career paths and achieve success.”
As for Julianna Payne, she is continuing to hone her skills. She entered her gluten-free chocolate/orange cupcakes at the recent Solano County Fair, Vallejo and drew rave reviews from the judges, staff and volunteers who sampled the cupcakes.
Soon she will be teaching other 4-H'ers as she herself was taught.
“I plan on giving back to 4-H this year by becoming a project leader myself," Julianna said. "I will be teaching a cupcake project for 5-to-8-year-olds in the Sherwood Forest 4-H Club."

The findings, reported today (Aug. 10), in the journal Proceedings of the National Academy of Sciences, call into question the effectiveness of removing non-crop vegetation as a way to reduce field contamination of fresh produce by disease-causing pathogens. This practice led to extensive loss of habitat in a region that is globally important for food production and natural resources.
The practice was implemented largely in response to a 2006 outbreak of pathogenic E. coli in packaged spinach that killed three people and sickened hundreds of others in the United States. That outbreak was traced to a farm in California's Central Coast, a region that supplies more than 70 percent of the country's salad vegetables. The disease-causing E. coli strain was found throughout the farm environment — including in the feces of nearby cattle and wild pigs — but the cause of the outbreak has never been officially determined.
"Wildlife took much of the blame for that outbreak, even though rates of E. coli in wildlife are generally very low," said study lead author Daniel Karp, a NatureNet postdoctoral research fellow in UC Berkeley's Department of Environmental Science, Policy and Management and The Nature Conservancy. "Now, growers are pressured by buyers to implement practices meant to discourage wildlife from approaching fields of produce. This includes clearing bushes, plants and trees that might serve as habitat or food sources for wild animals. Our study found that this practice has not led to the reductions in E. coli and Salmonella that people were hoping for."
Instead, the study authors noted that the presence of diverse habitats bordering food crops can actually provide a number of agricultural benefits.
"There is strong evidence that natural habitats surrounding crop fields encourage wild bee populations and help the production of pollinated food crops," said study senior author Claire Kremen, a UC Berkeley professor of environmental science, policy and management. "There have also been studies that suggest that a landscape with diverse plant life can filter out agrichemical runoff and even bacteria. Changing this dynamic shouldn't be taken lightly."
‘No reason to continue' habitat removal
The researchers analyzed about 250,000 tests of produce, irrigation waters and rodents conducted by industry and academics from 2007 through 2013. The tests were conducted on samples from 295 farms in the United States, Mexico and Chile, and targeted the presence of pathogenic E. coli, Salmonella and generic strains of E. coli. The researchers combined the test data with a fine-scale land-use map to identify characteristics of the landscape surrounding the agricultural fields.
The researchers found that the removal of riparian or other vegetation did not result in lower detection of pathogens in produce, water or rodents. Overall, the prevalence of pathogenic E. coli in leafy green vegetables had increased since the outbreak, even as growers removed non-crop flora. In fact, the growers who removed the most vegetation experienced the greatest increase in pathogenic E. coli and Salmonella in their vegetables over time.
"Clearing surrounding vegetation is a costly, labor-intensive practice that threatens wildlife habitat," said Karp. "Since it does not improve food safety, there is no reason to continue this practice."
The study did find, however, that the likelihood of detecting pathogenic E. coli was greater when fields were within 1.5 kilometers of grazeable land than when they were farther away.
"It is unclear whether it was the cattle or wildlife grazing on those lands that were responsible for the elevated pathogen levels, but there are a number of ways that farming and ranching can co-exist in a diversified system," said Karp.
Some suggestions include:
Leaving strips of vegetation between the grazed areas and fresh produce areas
Fencing off upstream waterways from cattle to prevent waste from going downstream
Planting crops that are usually cooked before being eaten – such as corn, artichokes and wheat – between fresh produce fields and grazeable lands
Reforming farming practices
After the 2006 E. coli outbreak in spinach, California's agricultural industry implemented a voluntary certification program called the Leafy Green Products Handler Marketing Agreement. At the federal level, in 2011 President Obama signed the Food Safety Modernization Act, considered one of the most sweeping reforms in farming practices in decades. Both efforts shift the focus to preventing rather than responding to outbreaks.
Notably, neither the federal law nor the state program calls for the removal of wildlife habitat surrounding crops, but private buyers, keen on retaining consumer confidence in their products, may still require growers to take steps that go beyond government regulations.
"The real worry for me is that federal law will be interpreted as the floor rather than the ceiling of what farmers should do," said Karp. "There is this misguided idea that agricultural fields should be a sanitized, sterilized environment, like a hospital, but nature doesn't work that way."

Ten large, shiny tanks stand near the Robert Mondavi Institute for Wine and Food Science at UC Davis, holding more than a year of rainwater and the key to processing food and drink during a drought. The water tanks, and the teaching-and-research winery they support, are showing students and winemakers throughout the world how to reduce processing costs, improve wine quality, and protect the planet's dwindling natural resources.
Roger Boulton, UC Davis professor of enology and chemical engineering. “We're demonstrating how you can operate a winery, brewery, or any food processing plant with the water that falls and the sun that shines on your roof.”
The work is the latest in more than a century of trail-blazing viticulture and enology science at UC Davis. UC Davis researchers are working with Cooperative Extension specialists and farm advisors with UC Agriculture and Natural Resources to help winemakers and grape growers sustainably produce premium wine.
Water is critical to winemakers in drought-stricken California and beyond. Grapes aren't a very thirsty crop to grow, but keeping fermentors clean is another story.
A typical winery uses four to six gallons of water after the grapes are harvested to produce one gallon of wine, and most of that water is used to wash equipment. Boulton and David Block, chair of the UC Davis Department of Viticulture and Enology, are developing self-cleaning fermentors capable of recycling 90 percent of that water. The goal: affordable technology and alternative practices that use less than one gallon of water to produce one gallon of wine.
Winemakers currently remove sticky, fermented, grape residue from tanks with water and elbow grease. Clean-in-place technology replaces hand-cleaning with an automated system that sprays tanks with diluted solutions of potassium hydroxide and potassium bisulfate.
“The dairy industry has used clean-in-place technology since the 1960s and the pharmaceutical industry since the 1990s,” says Block, a chemical engineer and enologist who helped the pharmaceutical industry manage clean-in-place technology before coming to UC Davis in 2008. “It's a little different with dairy and pharmaceuticals, where poor sanitation can kill you, but the concept is similar.”
“We will filter and reuse that water at least five times, hopefully one day up to 10 times,” Boulton says. “It's not waste water. It has no phosphates, no nitrates, and no chlorine. Clean-in-place technology represents a huge potential for water and labor savings.”
Industry is starting to notice.
“Clean-in-place technology is very attractive to us,” says Ashley Heisey, director of winemaking at Long Meadow Ranch in Rutherford and a UC Davis viticulture and enology graduate. “Water is such a critical issue. Long Meadow Ranch owners Ted, Chris, and Laddie Hall built our facilities with great concern for the environment, and thanks to UC Davis, we can take it one step further.”
In Sacramento, grocer Darrell Corti from Corti Brothers Market says where UC Davis leads, winemakers will eventually follow.
“What we know about grape-growing and winemaking is primarily due to the work they do at UC Davis,” Corti says.

Mary Lu Arpaia, a Cooperative Extension subtropical horticulturalist with UC Agriculture and Natural Resources (UC ANR) and the Department of Botany and Plant Sciences at UC Riverside, hosts an avocado tasting each month on the UCR campus. Attended typically by about 60 people, the tastings have grown in popularity over the years.
Eric Focht, a staff research associate in the Arpaia lab, helps organize the tastings; the guacamole he prepares specially for the occasion serves as an additional attraction. Focht has been working on avocados since 1999, the year he joined UCR as a staff member. His relationship with the campus, however, began before then; his father, now retired, was a professor on campus.
Typically, participants of the avocado tastings sample six avocados which come from UC ANR's South Coast Research and Extension Center in Irvine. “Hass control fruit are purchased from or donated by a packing house,” Focht says.
First, participants do a visual assessment of the fruit, evaluating texture, size and color. Next they step into a room where they do the blind tastings.
“The data is compiled and used to assess, among other things, which of our new breeding selections shows promise and should be pushed for eventual release,” says Focht, whose duties include coordinating field activities, designing field layouts, generating maps and databases, selecting avocado varieties of interest, interacting with growers and the public, troubleshooting, and directing the day-to-day operations of the lab when Arpaia is away.
“Right now our 465518-99 has been performing very well,” he says, “but in former years, its peak season is February through April. In the fall, Reed is always a good fruit with good flavor and texture. I prefer a fruit that peels easily and has good flavor. If it doesn't peel clean from the skin, I tend to overlook it for something else with good flavor and convenient packaging.”
The avocado growing season varies from variety to variety. By planting out several varieties, it is possible to have avocados year round in one's garden. Focht explains that the growing season varies regionally as well.
“The season in San Luis Obispo is months later than it is in San Diego,” he says.
Most avocado acreage in California is currently in Northern San Diego County. Most avocado acreage in the U.S. is in California. Other states with avocado industries include Florida and Texas. Worldwide, avocados are grown in Mexico, Chile, Peru, Israel, Australia, South Africa and New Zealand.
“An acre of avocado trees typically requires 2.5-4 acre-feet of water per year depending on weather and other factors,” he says. “The drought is resulting in lost acreage as farmers can either not afford or not find enough water for their trees. Successful farmers are having to modify their cultural practices to stay competitive.”
The next avocado tasting at UCR will be Aug. 12, 2015. For more information about the tastings, contact Focht.
three times the recommended amount of sugar every day, and about half the U.S. population consumes sugary drinks on any given day.
Excess sugar consumption contributes to obesity, tooth decay, early menses in girls, and chronic diseases including diabetes and heart disease. To add to the damage, doctors are now attributing too much dietary sugar to non-alcoholic fatty liver disease, which can lead to cirrhosis of the liver.
It's enough to make you sit up and listen to the warnings about too much soda, sugary drinks, and sugar-laden processed foods.
What is a sugary drink? It's any beverage, more or less, with added sugar or other sweeteners, including high-fructose corn syrup. The long list of beverages includes soda, lemonade, fruit punch, powdered fruit drinks, sports drinks, energy drinks, sweetened coffee and tea drinks, and many flavored milk products.
People are becoming aware of the concerns of too many sugary drinks, and steps are being taken to reduce their consumption. Some K-12 school districts across the nation are limiting sales of soda, and the City of Davis will soon require that restaurants offer milk or water as a first beverage choice with kids' meals.
UC Cooperative Extension, the county-based outreach arm of UC Agriculture and Natural Resources, is partnering with health agencies and conducting public service programs for youth and families about sugary drinks. UC ANR Cooperative Extension in San Joaquin County recently presented a "Rethink Your Drink" parent workshop in conjunction with the county's Office of Education, and Solano County Cooperative Extension is working with the California Department of public health to engage youth in "Rethink Your Drink" programs.
Lucia Kaiser, UC ANR Cooperative Extension nutrition specialist, co-authored a policy brief about California's rural immigrants who have poor-quality tap water, or perceive tap water to be bad. Kaiser, who is also a nutrition faculty member at UC Davis, noted that studies have found a link between water quality and consumption of sugary drinks, which is a concern in low-income communities that don't have resources for clean water.
As of this month (July 2015), UC San Francisco is no longer selling sugary beverages on its campus, and UCSF has launched a Healthy Beverage Initiative. UC Berkeley held a Sugar Challenge this year, and UC Davis is conducting a Sugar Beverage Study on women.
Scientists at UC San Francisco, UC Davis, UC ANR's Nutrition Policy Institute, and other universities are studying the health effects of sugar and implementing health outreach programs. And UC's Global Food Initiative is building on the momentum of excessive sugary-drink consumption.
A healthy alternative to sugary drinks? Water, of course. Many universities and public places are replacing traditional drinking fountains with water stations so that students and others can fill their own bottles and have water “on the go.” And UC President Janet Napolitano is working with the Nutrition Policy Institute on a bold and sensible request to place water on the USDA's MyPlate nutrition guidelines.
