Ordering a hamburger might soon come with more than a calorie count. Food systems account for about one-third of global greenhouse gas emissions, and some foods have larger environmental footprints than others. Some restaurants are beginning to display the environmental impact of food items on their menus. A new study led by researchers at the University of California, Davis, shows that climate labels can nudge people toward more environmentally friendly food choices.

As California lawmakers consider legislation that would require “high sugar” warning labels on restaurant menus, a University of California, Davis, study shows that the labels are effective in dissuading diners from ordering sugary items.

Packaged foods offer convenience for families and individuals, but they can be a major source of saturated fat, sodium and added sugars, which when consumed in excess contribute to chronic disease. To help people build healthier diets, the U.S. Food and Drug Administration proposed a new front-of-package nutrition label in January 2025 that would inform consumers about the presence of these nutrients.

The holidays are full of flavorful dishes and family traditions. Whether it’s homemade stuffing or a cookie swap, all foods are meant to be enjoyed this time of year. Maintaining a healthy approach to eating during the holiday season may feel overwhelming, but Debbie Fetter, associate professor of teaching with the UC Davis Department of Nutrition, has some helpful pointers to help everyone feel good about those once-a-year favorites (hello, pumpkin pie).

The early days with a baby can be overwhelming. Having someone who understands, especially in your own language, can make all the difference. A recent donation to UC Davis is helping ease financial barriers for bilingual students training to become lactation consultants, so they can bring that care to their communities.

At the end of a grocery run, shoppers in Berkeley are now more likely to face fruits and nuts than candy and soda in the checkout lane. A first-of-its-kind city ordinance that took effect in 2021 requires large grocery stores and other retailers to replace sugary drinks and sweets at checkout with healthier options like water, nuts, seeds and fruit.

Pancreatic cancer is one of the deadliest forms of cancer, killing 87% of patients within five years. Previous studies have shown that obesity can increase pancreatic cancer risk by around 50%. In a new study from the University of California, Davis, researchers showed evidence that switching from a high-fat diet to a low-fat diet slowed pancreatic precancer development in mice, even after weight gain and precancerous changes began. The research was published in the Journal of Nutrition.

Take a stroll down the middle aisles of any American grocery store, and you’ll be surrounded by rows of brightly colored packaged macaroni and cheese, instant soups and chips in all forms and flavors — all with long ingredient lists. These and other familiar favorites offer consumers a convenient, tasty and often affordable meal or snack.

Is sauerkraut more than just a tangy topping? A new University of California, Davis, study published in Applied and Environmental Microbiology suggests that the fermented cabbage could help protect your gut, which is an essential part of overall health, supporting digestion and protecting against illness.

Four researchers with the UC Davis Department of Nutrition are being recognized for their contributions to advancing nutrition science and health.
