Restaurant patrons with their varied food preferences play a huge role in determining which food items are included on the menu. Now an international team of researchers, including a UC Davis plant scientist, is finding that plant-eating insects do much the same in the natural world, maintaining and shaping the genetic variation of their host plants in a geographic area.
The plant-grazing bugs accomplish this by forcing the plants to create diverse natural defenses to avoid being eaten, which in turn shapes the genetic makeup of the plants in a region. The researchers discovered this by studying aphids and the broccoli-like research plant Arabidopsis thaliana. Their findings provide the first measurable evidence...

Two weeks ago, my colleague wrote about LA County Cooperative Extension’s popular “Grow LA Victory Garden” initiative – Resources for beginning vegetable gardeners develop from LA initiative. This exciting initiative has achieved great success in LA County over the past two years by teaching more than 1,100 beginner gardeners how to grow their own vegetables at home through Master Gardener-led classes.
These classes impart an array of useful skills onto beginner gardeners, potentially translating into positive outcomes, such as improved diet and savings on...

Remember when you were a kid and it was Tommy’s birthday and his mom brought those delicious cupcakes with the mounds of frosting to school? Picture with me all that syrupy sweet frosting in dazzling colors piled to the sky on top of a fluffy cupcake. While we are visualizing cupcakes, let’s do some cupcake math. If a teacher celebrates 30 students’ birthdays during the year, or about one per week in a nine-month school year, in addition to holidays like Halloween, Christmas, Valentines, and St. Patrick’s day, that can add up to a lot of sugary treats.
MyPlate teaches moderation, so there is nothing wrong with a

What we know about eating, not eating and overeating has been investigated by research universities and university-trained scientists since the 1920s. The Journal of Nutrition began publishing in 1928. Now 2.5 million inquiries each month probe a massive body of knowledge about the nature of our evolving physical and cultural relationship with food, with at least 30 more food and nutrition journals collecting and dispersing this science globally.
The result: Americans spend more time debating what to eat than at any other time in history. The firmly held beliefs of most adults about what should be eaten or avoided have origins in the history of...

Nutrition, food security and sufficient family incomes are challenges in many parts of the world. Half the world’s people live in rural areas in developing countries. Because hunger and malnutrition are often linked to poverty, providing economic opportunities through horticultural production not only helps family incomes, but also addresses food security and nutrition. Training women to produce and market horticultural crops in the developing world also helps provide a much-needed income stream for families with children.
UC Davis is addressing food security and economic development in Africa, Southeast Asia, Central America, and elsewhere, by coordinating an...
