初夏气温波动大宜食红色果蔬增强抵抗力

发布时间：2011-05-30 来源：新华网

近期，我国大部地区都经历了气温变化的“过山车”，前一天还是闷热难耐，随着一场大风或者降雨，气温马上“蹦极”，让人们感觉从盛夏回到初春。气象专家认为，初夏极容易出现大幅度气温变化，体弱者应做好防护。

　　海南省气象灾害预警中心高级工程师黄光瑞说，初夏时节，由于处在季节交替时期，气候由温和逐渐转为炎热，但也会时常有冷空气影响，这就造成了气温上下波动较大的现象。此时一些抵抗力差的人群、老人和孩子往往适应不了这种变化，通常会出现食欲不振、肠胃不适、嗓子上火、咽喉肿痛、体内发热、感冒发烧等症状，应该做好防护。

　　海南省妇幼保健院的有关专家认为，鉴于初夏时节气温变化大，应注重食物调养，着眼于清热解暑、健脾益气，宜食红色果蔬增强抵抗力。宜食用清淡爽口、少油腻、低脂、低盐、低糖、低胆固醇、低刺激、多维生素且易消化的食物，可多饮绿豆汤、赤豆汤、酸梅汤及绿茶，防止体内积热。不宜进食羊肉、狗肉、麻辣火锅以及辣椒、花椒、胡椒等大辛大热之品。

　　专家建议体弱多病者应多吃一些红色类果蔬，如红苹果、红辣椒、西红柿、胡萝卜等，这些果蔬可以提供丰富的维生素，也富含微量元素，不仅能增强抵抗力，并且其所含的抗感冒因子，可以直接抵抗感冒病毒。另外，红枣、红薯、红苋菜等红色果蔬，富含胡萝卜素，能参与合成维生素Ａ，对人体上皮组织和呼吸道黏膜等都有很强的保护作用。
