The summer solstice is coming up…and while most of us have been trained to slather on the sunscreen, we don’t want to completely block out the skin’s natural production of vitamin D from the sun. As with everything, moderation is key. UC San Diego researcher Cedric Garland explains.

Sunscreens completely eliminate the synthesis of vitamin D more effectively than they reduce the risk of cancer or any other outcome. The wisest thing to do would be when a person is out in the sun, to skip the sunscreen for the first 10 or 15 minutes — just keep it in the pocket, allow the sun to create vitamin D in the skin, then put on a hat and if desired, wear a sunscreen — although choose it very carefully to make sure it’s a safe sunscreen.

Exposure to sunlight has been found to lower blood pressure and cut the risk of heart attack and stroke and Garland has linked vitamin D produced by sunlight to a significant reduction in colon and breast cancers. Garland says one does not need to exceed 15 minutes in the sun because our skin synthesizes all that it needs in that amount of time.

UC President Janet Napolitano announced a major University of California initiative intended to marshal resources across the UC system to address global challenges related to food.
The UC Global Food Initiative grows out of a commitment by Napolitano and the 10 UC campus chancellors to work collectively to intensify and expand the efforts of the world’s premier public research university to support healthy eating, sustainable agriculture and food security. Napolitano says the goal is far-reaching.

It is to do all we can to help the world learn to feed itself in ways that are healthy and sustainable in the use of resources. Our starting blocks for this initiative are our 10 campuses, our Division of Agriculture and Natural Resources, and the Lawrence Berkeley National Laboratory. That power of 10-plus makes UC well poised to take on this challenge on a scale not possible by any other higher education entity in the world.
