◤亲子家庭◢ 孩子嗜重咸,因为身体缺盐?
孩子尽挑垃圾食物吃、尤其喜欢吃口味重咸的零食,在责备或纠正孩子之前,先关心与探究:孩子的身体是否缺乏盐分?

有些父母发现孩子特别爱吃含味精的零食,事实上,孩子爱吃的不是零食,多半是需求更多盐分,想吃点心零食,是“盐分摄取不足”的讯号。
身体脱水讯号
越是肾上腺疲劳、健康状况不佳的孩子,越喜欢吃重咸。肾上腺疲劳时,钠离子容易随著水分通过肾脏,成为尿液的一部分排出体外。也就是说,身体对盐分的吸收不良,不仅导致盐分不足,还会陷入脱水状态。
陷入脱水状态的孩子,基本上不会有自觉症状,当然也不懂得告诉大人说自己缺水了。觉得口渴就会想喝水,这是人体的本能,孩子不会知道自己是否喝足了身体运作所需的水,或是否摄取足够的矿物质。

肾上腺复原需要盐
受到近年来的健康风潮影响,妈妈做菜非常小心翼翼,调味总是少油少盐。肾上腺疲劳的孩子需要更多盐分,家中却总是吃减盐的淡口味,所以疲劳的肾上腺难以复原,因而本能的想从其他地方多吃一点盐。
父母抱怨孩子,“总是爱吃薯片薯条这类垃圾食物”、“外食专挑重口味的拉麵吃”,其实无论吃薯片还是拉麵,都是吃盐的代偿行为。解决方法是将盐、酱油放在家裡的餐桌上,让孩子自行加,加到他自己满意为止,通常人的身体会对太咸自然反应拒绝。当身体吃够所需的盐分,自然就不会想再吃咸了。基本上,孩子不会有盐分(注意仅限天然盐)摄取过量的问题,反倒是吃薯条、拉麵这类代偿行为的问题大很多。

喝淡盐水消疲劳
不过,有些孩子的父母还是应该坚持减盐。因为对盐分的需求量本来就有个体差异,所以爸爸、妈妈和孩子各有各的浓淡口味很正常。医生门诊时,只要看孩子眼窝凹陷,立即可知身体脱水。给眼窝深陷的孩子喝盐水,他们会说好好喝,半小时后,原本软趴趴的孩子就有了活力。可是同一杯盐水给妈妈喝,妈妈会感觉咸到根本无法入口。人的味觉有如此大的差异,说明每个人的盐分不足程度大有不同。

爸妈也许担心,孩子吃这么咸可怎么得了,但是别忽略了孩子的活动量与大人不同。他们每天到处走动,还要揹书包上下学,何况还处在发育期。孩子早上起床依旧疲劳未消,浑身倦怠提不起劲,可以立即给他喝一杯淡盐水(一杯水添加小半匙的天然盐)。盐水的浓度不必太计较,因为每个人感到“好喝”的浓度并不一样。此外,医生提醒添加盐巴时,请选用富含矿物质的天然盐或岩盐,取代精制盐。
