leaf="">失眠,已经成为困扰当代人的一个常见问题。有不少人无论吃什么保健品,无论换什么床垫、枕头,甚至坚持每天运动,躺在床上还是辗转反侧,或者频频发生夜醒。</span></span></p><p style="line-height:2em;"><span leaf=""><br/></span></p><p style="line-height:2em;"><span style="letter-spacing:2px;"><span leaf="">如果有以上情况,建议思考一下有没有这个原因——主食吃得太少,特别是晚餐少吃或不吃主食导致的失眠。</span></span><span style="color:#ffa900;"><strong><span style="letter-spacing: 2px;"><span leaf="">这种因缺乏碳水化合物而造成的失眠,不是吃保健品就能改善的,而是需要把无糖无油的主食吃够。</span></span></strong></span></p><p style="line-height:2em;"><span style="color:#ffa900;"><strong><span style="letter-spacing: 2px;"><span

style="line-height:2em;"><span style="letter-spacing:2px;"><span leaf="">一项随机对照研究发现,</span><strong><span style="letter-spacing: 2px;color: rgb(255, 169, 0);"><span leaf="">与运动后不吃碳水化合物相比,晚间运动之后增加碳水化合物供应能有效地提升入睡效果和睡眠质量。</span></span></strong></span></p><p style="line-height:2em;"><span leaf=""><br/></span></p><p style="line-height:2em;"><span style="letter-spacing:2px;"><span leaf="">虽然富含蛋白质的食物也同时富含B族维生素,适量摄入对睡眠也有帮助,但如果蛋白质食物过多,有可能会适得其反。</span></span><span style="letter-spacing:2px;"><span

leaf="">其科学原因主要有以下几点:</span></span></p><p style="line-height:2em;"><span leaf=""><br/></span></p><p style="line-height:2em;"><span style="letter-spacing:2px;"><span leaf="">■ 蛋白质有较高的食物热效应,容易使人兴奋,所以过多的蛋白质食物不利于安静入眠。</span></span></p><p style="line-height:2em;"><span leaf=""><br/></span></p><p style="line-height:2em;"><span style="letter-spacing:2px;"><span leaf="">■ 蛋白质、脂肪含量高的食物消化速度慢,加重夜间胃肠消化负担,从而影响睡眠质量。</span></span></p><p style="line-height:2em;"><span leaf=""><br/></span></p><p style="line-height:2em;"><span style="letter-spacing:2px;"><span leaf="">■ 如果主食不足,其他食物也没有相应增加,晚间会产生饥饿感,影响入睡和睡眠质量。</span></span></p><p style="line-height:2em;"><span leaf=""><br/></span></p><p style="line-height:2em;"><span style="letter-spacing:2px;"><span leaf="">此外,还有两个可能原因:</span></span></p><p style="line-height:2em;"><span leaf=""><br/></span></p><p style="line-height:2em;"><span style="color:#ffa900;"><strong><span style="letter-spacing: 2px;"><span leaf="">一是适度的淀粉类食物能帮助血糖水平保持稳定,避免夜间低血糖。</span></span></strong></span><span style="letter-spacing:2px;"><span leaf="">有些朋友夜间频繁惊醒或噩梦,可能是由于碳水化合物摄入过少,肝糖原不足,导致夜间血糖偏低。而血糖的过度降低是一种强烈的应激,会升高压力激素水平,使人容易夜间醒来并难以再次入睡。</span></span></p><p style="line-height:2em;"><span leaf=""><br/></span></p><p style="line-height:2em;"><span style="letter-spacing:2px;"><span leaf="">二是在晚餐不吃或少吃碳水化合物的情况下,为了维持血糖稳定,</span><strong><span style="color: rgb(255, 169, 0);"><span leaf="">身体不得不拆解蛋白质来异生葡萄糖,导致夜间肝脏工作负担加重,也可能会影响睡眠的质量。</span></span></strong></span></p><p><span leaf=""><br/></span></p><p style="line-height:2em;"><span leaf=""><br/></span></p><section
