AFAR grantee Valter Longo, Ph.D., led a study profiled by NPR on March 5, which “found that Americans who ate a diet rich with animal protein during middle age were more likely to die from cancer and other causes.”

The study, which tracked 6,000 older adults, used a survey to track diet patterns in middle-aged and older adults. While eating too much red meat or other protein-rich meats during middle age proved harmful, for adults over 65, a protein-abundant diet actually increased longevity and overall wellbeing. According to Dr. Longo, these effects are explained by changes in IGF-1, a growth hormone, which helps promote growth in people’s younger years, but speeds up the aging process later on.

Dr. Longo was a 1998 recipient of an AFAR Award in the Biology of Aging and this year’s recipient of the Vincent Cristofalo Rising Star in Aging Research Award. He is the director of the Longevity Institute, a Professor of Gerontology and Biological Sciences, and the Edna Jones Chair of Biogerontology at University of Southern California, Los Angeles.
