New evidence supporting a link between vitamin D sufficiency and cognitive ability is among the new nutrition and health findings noted in the latest issue of the Agricultural Research Service (ARS) Food and Nutrition Research Briefs and its Spanish-language edition (Informe de investigaciones de alimentos y nutrición). ARS is the chief scientific research agency of the U.S. Department of Agriculture (USDA).
The popular online newsletter reports discoveries from researchers at USDA-ARS laboratories nationwide.
Among other findings, the current issue reports that:
Six natural plant compounds including luteolin have been shown for first time to all inhibit the enzyme TBK1, which activates a biochemical signal that leads to inflammation.
More than 700 genes that give microbes like Salmonella and E. coli the ability to resist antibiotics and other antimicrobial compounds have been detected.
Phenolic components in olive oil have been found to actually modify genes that are involved in the inflammatory response.
A new model that can predict an individual's need for vitamin D has been developed.
