摘要：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.
