Short-Term Hemodynamic Effects of Modern Wheat Products Substitution in Diet with Ancient Wheat Products: A Cross-Over, Randomized Clinical Trial.

ABSTRACT: Recent evidence suggests that bioactive compounds isolated from cereals and legumes could exert some metabolic and vascular effects in humans. Due to the recent identification of a non-specific lipid transfer protein (nsLTP2) in wheat with antioxidant and anti-inflammatory activity, we aimed to comparatively test the hemodynamic and metabolic effects of ancient wheat foodstuffs (made of organic KAMUT® khorasan wheat) or modern wheat ones, made of a mixture of organic modern commercial durum (T. durum) varieties and soft wheat (T. aestivum), with different nsLTP2 content. Thus, we carried out a randomized, cross-over clinical trial on 63 non-diabetic healthy volunteers (aged 40?70 years) with systolic blood pressure (SBP) 130?139 mmHg and/or diastolic blood pressure (DBP) 85?90 mmHg (pre-hypertensive/borderline high pressure subjects). Each treatment period lasted four weeks. After ancient wheat foodstuffs intake, subjects experienced a significant improvement in triglycerides (-9.8% vs. baseline and -14.5% versus modern wheat), fasting plasma glucose (-4.3% versus baseline and -31.6% versus modern wheat), diurnal SBP (-3.1% vs. baseline and ?30.2% vs. modern wheat) and nocturnal SBP (-3.2% vs. baseline and -36.8% vs. modern wheat), and pulse volume change (+4.2% vs. baseline and +2.3% vs. modern wheat) (p < 0.05 vs. baseline and versus modern wheat foodstuffs intake). Therefore, our findings show that substituting modern wheat products in diet with ancient wheat ones, might exert a mild improvement in 24-h SBP and endothelial reactivity in pre-hypertensive healthy subjects.

Project description:In a double-blind, crossover, randomized and placebo-controlled trial; 28 men and women ingested a placebo (PLA), 3 g of creatine nitrate (CNL), and 6 g of creatine nitrate (CNH) for 6 days. Participants repeated the experiment with the alternate supplements after a 7-day washout. Hemodynamic responses to a postural challenge, fasting blood samples, and bench press, leg press, and cycling time trial performance and recovery were assessed. Data were analyzed by univariate, multivariate, and repeated measures general linear models (GLM). No significant differences were found among treatments for hemodynamic responses, clinical blood markers or self-reported side effects. After 5 days of supplementation, one repetition maximum (1RM) bench press improved significantly for CNH (mean change, 95% CI; 6.1 [3.5, 8.7] kg) but not PLA (0.7 [-1.6, 3.0] kg or CNL (2.0 [-0.9, 4.9] kg, CNH, p = 0.01). CNH participants also tended to experience an attenuated loss in 1RM strength during the recovery performance tests following supplementation on day 5 (PLA: -9.3 [-13.5, -5.0], CNL: -9.3 [-13.5, -5.1], CNH: -3.9 [-6.6, -1.2] kg, p = 0.07). After 5 days, pre-supplementation 1RM leg press values increased significantly, only with CNH (24.7 [8.8, 40.6] kg, but not PLA (13.9 [-15.7, 43.5] or CNL (14.6 [-0.5, 29.7]). Further, post-supplementation 1RM leg press recovery did not decrease significantly for CNH (-13.3 [-31.9, 5.3], but did for PLA (-30.5 [-53.4, -7.7] and CNL (-29.0 [-49.5, -8.4]). CNL treatment promoted an increase in bench press repetitions at 70% of 1RM during recovery on day 5 (PLA: 0.4 [-0.8, 1.6], CNL: 0.9 [0.35, 1.5], CNH: 0.5 [-0.2, 0.3], p = 0.56), greater leg press endurance prior to supplementation on day 5 (PLA: -0.2 [-1.6, 1.2], CNL: 0.9 [0.2, 1.6], CNH: 0.2 [-0.5, 0.9], p = 0.25) and greater leg press endurance during recovery on day 5 (PLA: -0.03 [-1.2, 1.1], CNL: 1.1 [0.3, 1.9], CNH: 0.4 [-0.4, 1.2], p = 0.23). Cycling time trial performance (4 km) was not affected. Results indicate that creatine nitrate supplementation, up to a 6 g dose, for 6 days, appears to be safe and provide some ergogenic benefit.
