连日来的雾霾天气，引发市民热议：雾霾天防空气污染该吃啥？一些市民认为，吃猪血旺和黑木耳能防PM2.5，导致最近几天市场上的猪血和黑木耳热销。相关专家认为，这种说法不太科学。

　　最近微博上流传了几种预防PM2.5的“攻略”，其中包括吃凉拌黑木耳、猪血旺。南昌大学生命科学与食品工程学院教授欧阳珊认为，黑木耳的主要成分是木耳多糖，它能够吸附空气中的污染粒子，但是在消化道里它是不被消化的。“空气中的污染颗粒更多的是在呼吸道，木耳多糖无法对它产生作用，所以吃黑木耳、猪血能预防PM2.5的说法不太科学。”

　　省人民医院呼吸内科一名医生说，合理的膳食对于减少吸入粉尘的确有积极的作用。研究表明,吸入性颗粒早期会出现免疫力降低,而适量的优质蛋白质对于提高免疫有很重要的作用。动物实验表明,高蛋白饲料能增加染尘老鼠的抵抗力,临床也发现蛋白质在吸入粉尘早期有保护肺泡上皮细胞免受毒害的作用。医生提示，可多吃葡萄、橘子、紫甘蓝、紫薯、番茄等富含维生素、植物化学成分的蔬菜水果。（记者 杜金存）
