On a Friday evening in a San Francisco conference room, food and technology leaders – including nutrition expert Carl Keen, a UC Davis professor affiliated with the UC Agriculture and Natural Resources Ag Experiment Station – spoke to a mixed audience on the need for innovation in adapting populations across the world to changing food systems.
In the crowd, one inspired undergraduate student from UC Davis thumbed together some notes on his phone. The next day he stood in front of everyone at the event – more than 250 in all – and pitched his newly formed idea for a nutrition app.
It drew a small team: a Silicon Valley entrepreneur, a UC Davis nutritionist and a UC Berkeley student. Over the next 40 hours they developed a software application that matches safe foods to patient medications. With the final presentations Sunday evening, the judges announced the winners.
Their project, called Took that? Eat this., won first place at the 2015 Food Hackathon. They now have sponsors and are developing their idea into a real consumer product. They are also flying out to the World Expo in Milan, Italy, in September – the first devoted to food and where an even larger food-themed hackathon will take place.
Breaking down the silos
“It's powerful how much happens in such a short period of time,” says Bob Adams, innovation adviser for the UC Davis World Food Center and a mentor for the hackathon teams. “It was a great experience for all the UC Davis students who participated, because they don't normally interact in projects with students from other programs.”
With nearly 9,000 total hours spent in developing the 18 different projects, the hackathon was declared by the organizers a success and a testament to the power of crowd sourcing.
A group of passionate techies, foodies, scholars, investors and entrepreneurs shut in a room for two days pushed them like never before to apply their diverse expertise toward tackling some of the biggest problems facing food and ag.
A university connecting ag and nutrition
Research and industry leaders are looking to this model as one way to seed California's innovation ecosystem across the state's agricultural horizons. As another example, Mars, Inc., which co-sponsored the hackathon, is investing in a new type of university-industry partnership with UC Davis and the World Food Center by establishing the Innovation Institute for Food and Health.
“All of us win from these new and needed collective investments in innovation in food, agriculture and health,” writes Mars chief scientist Harold Schmitz in a recent Sacramento Bee op-ed.
Howard-Yana Shapiro, also a Mars chief scientist and a UC Davis fellow, sees innovative food technology projects like those crafted at the hackathon as this decade's biggest investment arena.
“The next, larger human generation will face food challenges ranging from climate change and water stress to growing demands for upmarket foods,” he wrote in a LinkedIn article. “But from what I saw at the hackathon, the next generation is on it.”

Discolored leaves. Decaying roots. Dead wood. Mother Nature offers a fascinating and colorful backdrop of clues to track microscopic killers. Much like any medical mystery, experts are called in to diagnose or identify a disease from its symptoms and recommend management strategies to prevent further damage or loss of healthy plants.
Humans and animals depend on plants for their food supply and ultimately for their survival. When diseases threaten crops, a high-quality, affordable food supply is placed at risk. For growers, plant diseases can reduce crop yields. For consumers, reduced crop yields can drive higher food prices. Plant pathology research holds enormous implications for a sustainable food supply.
Florent Trouillas, who was named UC Cooperative Extension specialist in the Department of Plant Pathology at UC Davis and the Kearney Agricultural Research and Extension Center last year, explains the bottom line of most concern to growers.
"Once we identify a disease causal agent, a main question remains from growers. What growers really want to know is how to control the disease and prevent its spread to new healthy plants; they look to the University of California for solutions," Trouillas said.
A crisis in the food production system can impact other areas of society as well. In fact, history is filled with examples of how plant diseases influenced economies, environments and human societies.
Another historical illustration of plant pathology research occurred in the 1920s. The most common trees in the forests of the United States at the turn of the century were the majestic American chestnuts. The trees generated income for humans and the timber industry, served as a food source for people and animals, and provided habitat for wildlife. Then the trees started dying, until by the late 1920s, they had become the first tree in modern times on the brink of extinction. Plant pathologists were particularly adept at identifying plant diseases by this time and diagnosed the Cryphonectria parasitica fungus as the cause of the chestnut blight. By preventing the extinction of the pivotal species, plant pathology had a direct impact on the economy and the environment.
More recent major plant disease outbreaks in the United States involving plant pathology research have included Sudden Oak Death with devastating effects in California and Oregon forests, pitch canker killing California native pine species, and citrus canker in Florida, which has had a huge economic impact on the industry.
Veterinarians treat diseases in animals, physicians in humans. Trouillas describes the role of plant pathologists in similar terms. “We study the pathology of plant systems. Plant pathologists treat plants," he said.
Healthy plants ensure a sustainable food source and habitat for so many other organisms, including the human species.
The award was presented to the Aggie inventors during the finals of the three-day global iGEM (International Genetically Engineered Machines) competition in Boston. The competition, this year featuring 245 teams from Asia, Europe, Latin America and North America, challenges student teams to design and build biological systems or machines and present their inventions in the international competition.
The students had spent several months designing and building the palm-sized biosensor, which they dubbed OliView. The biosensor is equipped to quickly and easily evaluate the chemical profile of oil, providing producers, distributors, retailers and ultimately consumers with an effective, inexpensive way to ensure olive oil quality.
Verifying olive oil quality is a concern for consumers – many of whom are willing to pay higher prices for the health benefits and flavor of true, extra-virgin olive oil. And honest olive oil producers want to prevent other producers from passing off sub-par olive oil as the real deal, while retailers, distributors and producers want a quick, easy way to ensure olive oil quality.
In addition helping detect fraudulent olive oil, the students' new biosensor will also monitor for good oil that may have gone rancid with age.
The team of undergraduate students included Lucas Murray, Brian Tamsut, James Lucas, Sarah Ritz, Aaron Cohen and Simon Staley, with Yeonju Song serving as the “shadow” or alternate team member. You can tune into Aaron Cohen's recent Nov. 6 Science Friday interview during a discussion of synthetic biology.

On July 1, the University of California announced our new Global Food Initiative to address one of the critical issues of our time: How to sustainably and nutritiously feed a world population expected to reach eight billion by 2025.
UC's Division of Agriculture and Natural Resources is already a critical partner with California's farmers and consumers, providing growers and ranchers with scientifically tested production techniques, educating families about nutrition, improving food safety and addressing environmental concerns. With programs in every California county, our research and extension network in California reaches from Tulelake to El Centro and more than 130 countries working to solve agricultural problems at home and abroad.
The initiative will align the university's research, outreach and operations in a sustained effort to develop, demonstrate and export solutions — throughout California, the U.S. and the world — for food security, health and sustainability.

But the truth is, dietary advice is nothing new. Some of our rules for eating date back to ancient times as part of religious teachings, and food traditions are central to our understanding of culture. What is new over the last century or so is the application of science to our diets, so that we can know more exactly what nutrition science tells us is best when it comes to filling our plates.
A new book by a UC Davis researcher argues that modern dietary advice is not merely scientific, but also continues to have cultural, ethical and moral messages attached to it.
“Eating Right in America: The Cultural Politics of Food & Health” analyzes how modern dietary reform movements in the United States do not just tell us how to eat right, but how to become a good person and a good citizen. Can eating a certain way make us into different, somehow better people? And who defines what sort of people we should strive to become, though improved eating? Author Charlotte Biltekoff calls for changing the way we think about what it means to “eat right.”
The book analyzes four dietary reform movements over the last century:
- the rise of domestic science and home economics,
- the national nutrition program during World War II,
- the alternative food movement, and
- the anti-obesity movement.
These reform movements cover nutritional advancements such as the science of cooking, the discovery of vitamins, the shift in emphasis from contagious to chronic diseases, and the increasing importance of diet and lifestyle as a part of health. The book examines how dietary ideals have shifted, how social ideals have shifted alongside them — and the relationship between the two. Notions of middle class identity, good citizenship and individual responsibility each have been mixed in with nutritional advice before it is served to the public, according to the author.
Rose Hayden-Smith, leader of UC ANR’s Sustainable Food Systems strategic initiative and a historian of gardening, said she can't wait to read this book.
“This whole idea of both empirical and ethical considerations of food choices really makes sense to me, rooted in the Progressive Era,” she said. “All of these scientific advances don’t matter if people don’t adopt them. So I think it’s really important for scientists to understand the cultural context into which their work is going.”
Beth Mitcham, UC Cooperative Extension specialist in the Department of Plant Sciences at UC Davis, was intrigued by a presentation given by Biltekoff at UC Davis recently.
“This expands my way of thinking about the struggles we have with food choices and the potential for complicating well-intentioned messages,” she said. “We can’t ignore the scientific evidence that food choices have a huge impact on our health, but we must also realize when the things we’re saying are charged with judgments."
In a recent interview on Capital Public Radio, Biltekoff pointed out how analyzing history can shed light on difficult truths.
“History is such a great tool for learning to see things differently,” Biltekoff said. “The history that I tell in the book suggests that we worry so much about what is good to eat because of the social stakes involved in 'eating right.' Because it’s not just about our physical health, but also about our sense of self and about our social standing. There's a lot at stake that we may not be conscious of, but really is part and parcel of the conversation about 'good' food.”/span>
