大量医学研究资料表明,80%的癌症是由于生活环境和个人生活方式不良引起的。由于空气污染、吸烟、脂肪摄入过多、饮食习惯不良等因素所引发的肺癌、乳腺癌、结肠癌、胃癌等癌症的发病率明显增加,而这些因素相当一部分来源于家庭。专家们指出,创造良好的家庭生活环境和生活方式,对于癌症的预防具有相当重要的作用。首先,要注意饮食防癌。现代人工作繁忙,有不少家庭常一次购买大量食物如米、食用油、肉、杂粮、方便食品等堆放在家里备用。必须了解,不同的食品有着不同的贮存条件和保质期限。一次买回过多的食物难以保证不发生霉变或变质,而霉变食品中(尤其是大米、玉米、食油、花生、方便面等)含有致癌作 A large number of medical research data show that 80% of cancers are caused by bad living conditions and personal lifestyle. The incidence of cancers such as lung cancer, breast cancer, colon cancer, and gastric cancer caused by factors such as air pollution, smoking, excessive fat intake, and poor dietary habits has increased significantly, and a considerable part of these factors originate from families. Experts pointed out that creating a good family living environment and lifestyle has a very important role in the prevention of cancer. First of all, pay attention to diet to prevent cancer. Modern people are busy with work. Many families often buy large amounts of food such as rice, cooking oil, meat, grains, and convenience foods at home and store them at home. It must be understood that different foods have different storage conditions and shelf life. It is difficult to ensure that moldy or spoilage does not occur when buying too much food at one time, while moldy foods (especially rice, corn, edible oil, peanuts, instant noodles, etc.) contain carcinogenicity.
