A treatment for managing blood sugar levels might be as close as the local health food store, suggests a new research report published in the December 2015 issue of The FASEB Journal. Specifically scientists from Italy have found that when the plant and mammal hormone, abscisic acid, is taken in low doses, glycemia in both rats and humans is reduced. This suggests that by reducing the chronic stimulation by hyperglycemia of β-cells to the release of insulin, chronic low-dose abscisic acid administration may prolong the survival and function of these cells.

“These results warrant further studies, aimed at developing new pharmacologic approaches to diabetes prevention and/or treatment,” said Mirko Magnone, Ph.D., a researcher involved in the work from the Department of Experimental Medicine at the University of Genova School of Medicine in Genova, Italy.

Scientists examined the presence of abscisic acid in plants and fruits and explored the effect of abscisic acid-rich vegetable extracts on glycemia in rats and in humans. Synthetic abscisic acid, an abscisic acid-rich fruit extract, or placebo were administered to rats together with an oral glucose load. Then glycemia and insulinemia profiles were compared. Then a fruit extract or placebo was administered to human volunteers together with an oral glucose load or with a standard breakfast and lunch. Glucose and insulin levels were then compared with and without abscisic acid. Glycemia and insulinemia profiles from the human oral glucose tolerance tests were also compared with those from 12 normal subjects undergoing a standard oral glucose tolerance test.

“Mom always said, ‘eat your veggies,’ and now science backs up this advice,” said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. “High blood sugar levels predict the later consequences of diabetes, and while this hormone may not be a cure for diabetes, it should prove very useful in helping to control progression of the disease.”

The FASEB Journal is published by the Federation of the American Societies for Experimental Biology (FASEB). It is among the world’s most cited biology journals according to the Institute for Scientific Information and has been recognized by the Special Libraries Association as one of the top 100 most influential biomedical journals of the past century.

FASEB is composed of 27 societies with more than 120,000 members, making it the largest coalition of biomedical research associations in the United States. Our mission is to advance health and welfare by promoting progress and education in biological and biomedical sciences through service to our member societies and collaborative advocacy.
