With the COVID-19 pandemic ongoing, there has been growing consumer demand for natural health products to support their immune system. One successful example of establishing evidence for a beneficial effect of a food ingredient in this health area has been reported recently, based on a proof-of-concept trial accomplished by a&r. In a randomized, double blind, placebo-controlled study in healthy subjects, bell pepper rhamnogalacturonan-I polysaccharides were shown to enhance innate immune responsiveness (a dose-dependent increase of phagocytosis by granulocytes was observed).
