Regular consumption of dietary components with anti-inflammatory properties is a promising strategy for management of inflammation-associated diseases.Oats, increasingly consumed in various forms such as oatmeal, granola, and oat milk, contain noteworthy anti-inflammatory elements.Here we review the functional components of oats: the glycolipid digalactosyldiacylglycerol (DGDG), estolides (esters of hydroxy fatty acids and fatty acids), and the oat-specific glycolipid DGDG-monoestolides.DGDG and estolides have garnered interest as functional lipids, and their physiol. functions have been well documented.On the other hand, the biol. functions of DGDG-monoestolides have been relatively unknown despite the fact that they contain DGDG and estolides as building blocks.Therefore, we have isolated a major DGDG-monoestolide mol. species from oats, analyzed its structure, and investigated its anti-inflammatory properties.Further in-depth knowledge of the functional components of oats, including the DGDG-monoestolides introduced in this review, will hopefully pave the way for wider utilization of oats as a functional food.
