　　吃黑木耳、猪血旺可预防PM2.5 Eat black fungus/Pig blood prosperous can prevent PM2.5

　　有资料显示，PM2.5是指大气中直径小于或等于2.5微米的颗粒物，也称为可入肺颗粒物。PM2.5粒径小，富含大量的有毒、有害物质且在大气中的停留时间长、输送距离远，因而对人体健康和大气环境质量的影响很大。

The data shows,PM2.5 refers to the atmosphere diameter less than or equal to 2.5 micron particles,Also known as can into the lung particles.PM2.5 particle size small,Rich in a large amount of poisonous/Harmful substances in the atmosphere and stay for a long time/Conveying distance,So for the human health and atmospheric environment quality influence.

　　新浪微博上认证为“广东省中医学会药膳委员会委员”佘自强的博主发微博称，人的生理结构决定了其对PM2.5没有任何过滤能力；进入人体的PM2.5颗粒约有50%会沉积在肺中，导致肺组织部分硬化，是一种强致癌物，对人体健康危害极大。他介绍了几种预防PM2.5的攻略：戴口罩、洗肺，吃凉拌黑木耳、猪血旺等。

　　这种说法不太科学 This statement is not too science

　　对于微博的说法，中国农业大学食品学院营养与食品安全系主任、副教授何计国称，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。吃黑木耳、猪血能预防PM2.5的说法不太科学。”

For micro bo said,China agricultural university institute of food nutrition and food safety department/Associate professor any meter nations say,The main components of the black fungus is edible fungus polysaccharide,It can adsorption air pollution of the particle,But in the digestive tract it is not be digested."The air pollution is more particles in the respiratory tract,Edible fungus polysaccharide can't effect to it.Eat black fungus/Pig blood can prevent PM2.5 story doesn't science."

　　昨日下午，国家二级营养师胡杨说，阴霾对呼吸道健康有很大影响。黑木耳、血块儿含有丰富的抗氧化剂，吃这些食材能清肺和清除呼吸道里粉尘的说法，在民间流传已久，但食物无法进入到呼吸道。“就是清除也无法去取证，此说法的真实性有待验证。”

Yesterday afternoon,National secondary dieticians p. euphratica said,Haze has a great influence on respiratory health.Jew 's-ear/Blood block contains rich antioxidant,Eat these foods can clear lung and remove dust that the respiratory tract,In the folk spread already a long time,But food cannot enter the respiratory tract."Is clear and unable to obtain evidence,This is true remains to be verified."

　　如何减少空气污染对身体的影响？胡杨建议，多吃富含维生素、植物化学成分的蔬菜水果（一般指颜色比较显眼的蔬菜水果），如葡萄、橘子、紫甘蓝、紫薯、番茄等。河南商报
