最近,据美国《科技信息》报道:维生素C有助于预防高血压的发生。研究发现高血压病人血液中维生素C的浓度低于正常水平,如果每天摄取一克维生素C,可使收缩压降低。科学家认为这种机制是,维生素C可以清除小血管内破损的内皮细胞,防止动脉血管收缩而引起血压增高。维生素C广泛存在于绿色蔬菜和水果中,含维生素C较多的蔬菜有辣椒、芥菜、菜花、苦瓜、青蒜、山楂、酸枣 Recently, according to the US “Science and Technology Information” report: Vitamin C can help prevent the occurrence of high blood pressure. The study found that patients with blood pressure of vitamin C in the blood is lower than normal levels, if the daily intake of 1 g of vitamin C, can reduce systolic blood pressure. Scientists believe that this mechanism is that vitamin C can clear small blood vessels damaged endothelial cells, prevent arterial blood vessels caused by contraction and increased blood pressure. Vitamin C is widely found in green vegetables and fruits, vegetables containing more vitamin C are pepper, mustard, cauliflower, bitter gourd, garlic, hawthorn, jujube
