Abstract

The beer industry generates large amounts of leftover barley called brewers’ spent grain (BSG). Studies demonstrate fiber-rich grains like barley are associated with cardiovascular disease (CVD) risk reduction. This study investigated the effect of BSG on CVD risk factors including blood lipids, glucose, insulin, C-reactive protein, body composition, and blood pressure. A single-blind, randomized feeding trial was conducted in 37 healthy adults (26 ± 4 y; BMI 23 ± 3 kg/m2) who consumed muffins containing 10.4 g BSG (n=19) or 0 g BSG (n=18) daily for 8 weeks. Body composition, blood pressure, and fasting blood were collected at baseline and week 8. Fiber intake increased in the BSG group (P=0.003), but there was no effect on blood biomarkers, body composition, or blood pressure. Consuming 10.4 g BSG for 8 weeks is well tolerated and improves dietary fiber intake but does not significantly impact CVD risk factors in healthy adults.
