"These findings might help guide recommendations on important food sources of fructose in the prevention and management of diabetes," lead author John Sievenpiper said in a statement. "But the level of evidence is low and more high quality studies are needed."
The analysts did acknowledge some limitations, including small sample sizes, short follow-up periods and a limited variety of foods. However, they did note their research was in-depth and thorough.
The scientists now hope to continue their investigations and urge more health care providers “to be aware that harmful effects of fructose sugars on blood glucose seem to be mediated by energy and food source.”
