速溶芦笋粉改善睡眠作用研究

[目的]评价以芦笋为原料开发的功能食品速溶芦笋粉改善睡眠的功效。[方法]通过60名志愿者试食试验,每日食用1次,1次2袋(24 g),连续食用60 d,进行睡眠状况评估,同时测定安全性指标及失眠相关内分泌指标,观察速溶芦笋粉对人体睡眠障碍的改善作用。[结果]速溶芦笋粉可明显增加有失眠困扰测评者的有效睡眠时间,由5.1 h延长至6.1 h;缩短入睡时间,由50.4 min缩短到25.3 min;醒后再入睡时间明显减少,平均时间由46.5 min减少至19.5 min,食用前后差异显著(P0.05),测评者对睡眠质量改善满意度较高。食用后无肝肾功能影响,具有较好的安全性。速溶芦笋粉可以降低皮质醇、去甲肾上腺素水平,提高5-羟色胺、多巴胺水平。[结论]速溶芦笋粉有改善睡眠质量作用,安全有效,其改善睡眠作用可能与调节HPA轴或5-羟色胺分泌相关。
