何时吃甜食有利健康
提起甜食,多数人认为不吃或少吃为好。特别是一些中老年人对甜食尤其忌讳。然而,营养学家认为,选择最佳的时间吃甜食不但对身体无害,而且能充分发挥有益作用。一般来说,下列时间进食甜食为好。
运动前
人体在运动过程中,付出大量体能,而运动前又不宜饱餐,这时,适量吃些甜食可满足人体运动时所需的一定量的能量供应。
过于疲劳与饥饿时
这时体内热能失去过多,人体虚弱,吃些甜食,其中糖可比一般食物更快地被血液吸收,迅速补充体能。(推荐:饿时应少吃这些东西)
头晕恶心时
这时饮糖分高的水,可提高血糖增强抗病能力。
糖尿病低血糖时
由于过分控制糖分摄取而出现低血糖导致的休克症状时,饮糖水或其他甜性饮料,可使患者度过危机。 糖尿病病人怎么吃甜食 详细>>
呕吐或腹泻时
这时病人肠胃功能紊乱,有脱水症状,如喝一些盐糖水,有利于肠胃功能的恢复。
但有些时候吃甜食对身体不利。如饱餐以后吃甜食最易使体重增加,且过多的糖会刺激胰岛素分泌,易诱发糖尿病。睡前、饭前,将甜食当作每日的常规食品,都可导致牙病、食欲下降和发胖。
