<p>随着生活水平的提高，人们对食物的要求也越来越严格了。这种严格不仅仅存在于食材的选择方面，还存在于食物的口味方面。很多人吃菜习惯下多点盐，认为那样的菜才够味，殊不知重口味对健康非常不利，吃得太咸不但伤肾、导致钙质流失，还会令人长皱纹等等。</p><p style=""><strong style="margin: 0px; padding: 0px;">1. </strong><strong style="margin: 0px; padding: 0px;">食盐</strong><strong style="margin: 0px; padding: 0px;">过多伤肾</strong></p><p style=""> 大部分情况下，味道重的食物含盐量都高。盐就是氯化钠，它是一种防腐物质，具有一定的毒性。除了盐之外，味精、鸡精等增鲜产品，以及酱油、豆瓣酱、沙茶酱、辣椒酱、豆豉、蚝油、鱼露等所有咸味调味品也都含有大量的钠。过多的钠会增加肾脏负担，出现水肿症状，造成身体组织脱水。</p><p style=""><br /></p><p style=""> <strong style="margin: 0px; padding: 0px;"> 2. 食盐过多易引发</strong><strong style="margin: 0px; padding: 0px;">高血压</strong></p><p style=""> 世界卫生组织建议正常人每人每日盐摄入量不超过5g，中国营养学家建议不超过6g。 在我国，北方人平均每日食盐量15～20g，高血压患病率为10%；南方人平均每日食盐量12～13g，患病率约为5%～7%。经研究发现，盐易存积在血管壁内。血管的阻力越大，血压就越高，心肾等内脏的负荷就越重，机体正常代谢功能一旦被打乱，产生脑血管意外或心力衰竭的危险性就大幅度增加。 </p><p style="text-align:center"><img data-s="300,640" data-type="jpeg" src="http://mmbiz.qpic.cn/mmbiz/dx3KibwtDhvcM8DibX3OUibqRYI0icSDZNwKXPvu436Bw2Xh0yxetRMrPyxdyYnlGRB7wdtRutzSG8pZ33GE3Z33gg/0?wx_fmt=jpeg" data-ratio="0.8039702233250621" data-w="403" /></p><p style=""> <strong style="margin: 0px; padding: 0px;"> 3. 食盐过多易长皱纹</strong></p><p style=""> 食盐以钠离子和氯离子的形式存在于人体血液和体液中。这些物质在保持人体渗透压、酸碱平衡等方面起着非常重要的作用。如果吃盐过多，体内钠离子增加，就会导致面部细胞失水，从而造成皮肤老化，时间长了就会使皱纹增多。</p><p style=""> <strong style="margin: 0px; padding: 0px;"> 4. 吃盐过多易引发呼吸道疾病</strong></p><p style=""> 现代医学研究发现，人体内氯化钠浓度过高时，钠离子可抑制呼吸道细胞的活性，使细胞免疫力降低。同时由于口腔内唾液分泌减少，使口腔内溶菌酶减少，这样病毒更易于侵入呼吸道。最后，高盐饮食还会导致血中钠的浓度较高，易发生支气管炎。摄入太多的盐甚至会诱使气喘发作，使哮喘发病率增加。</p><p style=""> <strong style="margin: 0px; padding: 0px;"> 5. 食盐过多导致钙质流失</strong></p><p style=""> 盐中的主要成分——钠，含量约为40%，可以说是导致人体骨质流失的直接杀手。一般而言，人体的肾每天会将使用过的钠随着尿液排到体外，可是每排泄1000mg的钠，大约也会同时耗损26mg钙。这看起来似乎没有什么影响，可是人体需要排掉的钠越多，钙的消耗也就越大，最终必会影响到钙质。</p><p style="">饮食中钠盐过多，在肾小管重吸收时，可使过多的钠离子与钙离子相互竞争，钙的排泄增加，破坏了骨钙代谢的动态平衡，因而易导致人体缺钙，发生骨质疏松症甚至骨折。</p><p style=""> <strong style="margin: 0px; padding: 0px;">6. 食盐过多易患上</strong><strong style="margin: 0px; padding: 0px;">胃炎</strong><strong style="margin: 0px; padding: 0px;">、胃癌</strong></p><p style=""> 摄入过量的高盐食物后，因食盐的渗透压高，对胃黏膜会造成直接损害。高盐食物会使胃酸分泌减少，并抑制前列腺素E2的合成，而前列腺素E2具有提高胃黏膜抵抗力的作用，这样就使胃黏膜易受损而产生胃炎或胃溃疡。同时高盐食物中含有大量的硝酸盐，它在胃内被细菌转变为亚硝酸盐，然后与食物中的胺结合成亚硝酸铵，具有很强的致癌性。</p><p style=""><br /></p><p style=""><span style="margin: 0px;
