Breaking News! Vitamin A & Type 1 Diabetes

Type 1 diabetes is an autoimmune disease that can destroy the beta cells of the pancreas, which make and release the hormone, insulin. Scientists from the University of California, Davis, hypothesized that feeding diabetic, non-obese mice diets rich in polyphenols, or vitamin A, would lessen the autoimmune inflammatory process associated with type 1 diabetes.  These researchers studied 45 female, non-obese mice, and found the incidence of diabetes was reduced to 25% from 33% in mice receiving 1% dietary grape powder or vitamin A.*

In addition, vitamin A consumption seemed to lower the TNF-alpha protein, which has also been linked to type 1 diabetes.

More research studies are being put in place to study the effects of vitamin A to help fight diseases
affecting the immune system.
