Intake of antioxidant dietary fiber from spent coffee grounds improves the circadian rhythm and body weight management in human adults

Abstract

The aim of the present study was to evaluate the effects of acute and repeated intake of biscuits, containing as source of dietary fiber either spent coffee grounds ( added with fructooligosaccharides) or extracted coffee antioxidant dietary fiber ( obtained by ohmic procedure, on body weight management and CR of human volunteers Nutritional composition of biscuits TC, C ADFSCG and C SCG) was determined confirming a total fiber content of 5 3 4 and 1 7 g of fiber/ 45 g (administered portion), respectively Satiety increased after C ADFSCG consumption compared with TC and C SCG, with high area under the curve ( p 0 05 A d libitum food intake measured at breakfast decreased energy intake p 0 05 but no difference was observed at lunch However, total energy intake was significantly p 0 05 lower with C ADFSCG compared with C SCG and TC ADFSCG was well tolerated Physical activity, sleep quality and biological chronotype (morningness/ with melatonin has been used as a biological marker were improved by C ADFSCG and C SCG, suggesting its positive effect on CR regulation In the absence of other lifestyle changes, the new ADFSCG show promise to positively impact body weight management thus improving health, and could be considered as a potentially healthy functional ingredient for application in the food industry.
