Summary : Various components of nutrition are being increasingly demonstrated to have an impact on arterial stiffness and wave reflection. Caffeine and coffee have an unfavourable effect on aortic stiffness and wave reflection both acutely and chronically. Tea, which contains not only a great amount of flavonoids but also caffeine, stiffens acutely the arteries less than its caffeine content. Dark chocolate, also rich in flavonoids, has a beneficial acute effect on wave reflection, while its habitual consumption has a beneficial effect both on aortic stiffness and wave reflections. Moderate consumption of alcohol is beneficial for arterial stiffness and wave reflection, while high consumption may be deleterious. Salt restriction results in a rapid amelioration of arterial stiffness. Obesity (especially central) is generally associated with impaired arterial elastic properties, and weight loss is accompanied with improvement in arterial stiffness. Nutrition has a significant impact on cardiovascular risk. An important part of this impact may be mediated through its effect on arterial stiffness and wave reflection given their important pathophysiological and risk-predictive roles. |
