Access to healthy food does not always relate to the presence of a nearby supermarket, but instead requires a deeper look at poverty, race and other factors in a community, a UC Davis study suggests.
Lack of a supermarket does not necessarily make a county a “food desert,” argues Catherine Brinkley, who studies food systems and community development.
The study shifts the conversation begun in the 1990s, in which “food deserts” were described as communities that were either sparsely populated or had too many low-income residents to support a supermarket. The past research said this lack of access led to health problems such as obesity and diabetes. The popular policy response then was to leverage public funds to establish a supermarket.

Nearly 47 million people worldwide live with dementia, according to the Alzheimer’s Association. That number is expected to rise to 76 million by 2030. While there is no cure for dementia, scientists are investigating various drugs to help mitigate cognition loss associated with the condition.
UC Davis researchers propose that foods provide signals that influence the brain and other body systems.
When it comes to understanding and preventing age-related cognitive dysfunction, Professor Raymond Rodriguez, Department of Molecular and Cellular Biology in the College of Biological Sciences at UC Davis, looks to food for answers.
Synthetic DNA Approach is Key to Startup’s New Drug

The way Justin Siegel describes it, ordering synthetic DNA is almost as easy as ordering a pair of shoes online.
“You just type it in — or if the protein has been sequenced at one point, we can copy and paste — order it, and it shows up five days later.”

Plant scientists and wheat breeders now have a new tool to develop more nutritious and productive wheat varieties: A public online database of 10 million mutations in wheat genes. Scientists at UC Davis and three institutions in the UK created the database, which will allow scientists worldwide to study the function of every gene of wheat. The research will be reported in Proceedings of the National Academy of Sciences this week.
UC Davis Plant Sciences Professor, Jorge Dubcovsky is working to improve the yield and nutritional value of wheat, one of the world’s most important crops.
