Abstract
PURPOSE: Consumption of alternative flours, such as sprouted chickpea flour, has shown increased popularity in recent years. Foods rich in antioxidants have been shown to influence brachial artery flow-mediated dilation (FMD), a non-invasive test of a crucial layer of the artery called the endothelium. Partially replacing the semolina flour in pasta with sprouted chickpea flour (SCF) may acutely affect endothelial function post-digestion. We sought to determine if FMD was higher, lower, or the same post-digestion of pasta made with 60% semolina flour and 40% SCF (SCF40) vs. post-digestion of pasta made with 100% semolina flour (SEM100, i.e., control). METHODS:Trolox equivalent antioxidant capacity (TEAC) analysis was performed on the same flour samples. Healthy participants underwent ascreening visit and two randomized controlled meal data collection visits (SCF40 and SEM100). At each data collection visit, participants consumed 255 g of pasta with butter. FMD was assessed 2-3 h after pasta consumption. RESULTS: TEAC results showed that SCF40 (2.031 ± 0.096 mmol trolox/100 g sample) had significantly greater antioxidant capacity than SEM100 (1.736 ± 0.046 mmol trolox/100 g sample; p = 0.02). Twenty-two healthy participants (5 men and 17 women; 26 ± 2 years, 66.6 ± 2.3 kg, BMI = 24 ± 1 kg/m2, SBP = 114 ± 3 mmHg, DBP = 75 ± 2 mmHg, HR = 74 ± 3 BPM) were studied. FMD in the SCF40 condition (10.3% ± 1.2%) was greater than the SEM100 condition (7.9% ± 0.8%, p = 0.02). CONCLUSION: These data suggest that partial substitution with sprouted chickpea flour in place of semolina flour in pasta acutely improves post-digestion FMD, which may be beneficial for cardiovascular health (ClinicalTrials.gov Identifier: NCT03801486).
