近年来科学家们发现,人体对流感的易感性与食盐摄入量有关。高浓度钠盐具有强烈的渗透作用,这不仅能杀死细菌或抑制细菌的生长繁殖,同样也可影响人体细菌的防御功能。摄入食盐过多,一是可使唾液分泌少,口腔内存在的溶菌酶也相应减少,以致病毒在上呼吸道粘膜“落脚”更安全;二是 In recent years, scientists have found that the body’s susceptibility to influenza is related to salt intake. High concentrations of sodium salt has a strong infiltration, which not only can kill bacteria or inhibit bacterial growth and reproduction, but also can affect the body’s defense function. Too much salt intake, one can make less saliva secretion, the presence of oral lysozyme is also reduced, so that the virus in the upper respiratory tract mucosa “settled” safer; second is
