减肥、预防老年痴呆……食用辣椒还有这么多好处

科普中国-乐享健康 2017-12-19

  辣椒作为一种辛辣蔬菜,深受不少人的喜爱,有些人甚至“无辣不欢”,每顿饭都要吃辣椒,但也有些人认为辣椒过于辛辣,食用后会对人体造成一些不良影响。但实际上,只要适量食用,辣椒对身体是有一定好处的。那么,食用辣椒的好处是什么?有没有人不适合食用辣椒?

  “黄灯笼”辣椒成熟了。

  1.吃辣椒可以增加饱腹感,具有减肥作用。据环球网报道,辛辣食物让人更容易产生满腹感,因为辣椒、胡椒等辛辣调味料含有一种名叫辣椒素的物质,该物质能够活化人体代谢机能,同时还能有效抑制人体分泌容易产生饥饿感的荷尔蒙激素。

  2.吃辣椒有助于降低死亡率。据参考消息网报道,美国佛蒙特大学医学院的一项研究表明,常吃红辣椒有助于降低死亡率,尤其是由心脏病和中风引起的死亡。研究人员推测,这可能是因为红辣椒中的辣椒素有助于调节冠状动脉血流。

  3.吃辣椒可以降低帕金森症的患病风险。据《武汉晚报》报道,尼古丁能保护大脑神经元免遭帕金森症的侵害,而在多种茄科植物的果实中,辣椒、番茄、茄子、枸杞等植物均含有尼古丁。经常食用茄科属蔬菜,特别是辣椒,可以有效降低帕金森症的患病风险。

  4.吃辣椒可以预防老年痴呆。据人民健康网报道,吃辣椒具有活化脑细胞以及兴奋大脑的作用。辣椒含有的姜黄素可以预防老年痴呆,帮助肌肉在大量运动后恢复正常。而辣椒中的辣椒素能刺激大脑产生一种止痛物质——内啡肽,这种物质可以让大脑兴奋,使人产生愉悦感。

  虽然辣椒有以上功效,但仍需适量食用,吃得太多或是食用太辣的辣椒,都会引起身体不适,甚至危害健康。此外,并不是所有人都适宜食用辣椒,据《山西日报》报道,心脏不好的人,肾不好的人,胃酸过多的人,便秘者,口腔溃疡者,眼病病人,患慢性胃炎、胃溃疡、食管炎等胃部疾病的患者,正在服用某些药物的人都应避免食用辣椒。(王亚宇)
