新华社北京2月16日电（记者侠克）春节将至，节日期间饮食不规律、不节制，叠加作息紊乱、久坐少动等情况，可能引发各类健康问题。假期如 何科学饮食？记者采访了相关医学专家。 节日期间，亲朋好友相聚难免饮酒。北京友谊医院全科医学科主任医师乌依罕提示，头孢类、甲硝唑等药物与酒精会发生"双硫仑样反应"，引发 休克甚至死亡，服药前后7天严禁饮酒。慢性病患者，如高血压、糖尿病、肝病患者等饮酒会加重病情，需特别注意。 专家提示，食物塞进冰箱并不意味着万事大吉。冰箱中的李斯特菌，外号"冰箱杀手"，怕热却极其耐寒，在冰箱的冷藏温度下，不仅不"冬眠"， 反而能生长繁殖。如果剩菜没热透，这种菌进入人体，轻则腹泻，重则引发脓毒症或脑炎。"吃之前必须彻底加热。菜中心位置的温度要达到70℃ 以上，并且持续加热3分钟。只有这样，才能把李斯特菌和大部分病原菌彻底消除。"杨梓琪说。 此外，长期服药的患者特别是慢病患者，春节期间不可擅自停药。"尤其是高血压患者，血压的平稳是靠血液里药物浓度的恒定来维持的。停药一 天，药物浓度就像过山车一样跌下来，血压就会报复性反弹，增加心脑血管事件发生的风险。"乌依罕说，对于糖尿病患者，过年期间容易因生活 不规律 ...
