A | “高钾晚餐”最近成了网络热词。
B | 有人称“高钾晚餐”有助眠效果，甚至能替代助眠药物，有人认为高钾饮食能更好地减重。不少人特意调整晚餐食谱，多吃菠菜、山药、菌菇、香蕉等高钾食物。这种网红饮食方式真的靠谱吗?8月24日，极目新闻记者采访了武汉专家。 Police say there were around 100 people in the trailer, found in the late afternoon on Monday. The individuals have been described as migrants. One local reporter called it a possible human smuggling case.,Multiple SAPD sources tell me it’s at least 40 people dead. Sixteen others were taken to area hospitals in varying conditions. Death toll could rise. https://t.co/zdb5KC6Q4M— Dillon Collier (@dilloncollier) June 28, 2022,Border patrol officers were spotted arriving at the scene around 8 p.m. First responders were already attending to the victims and were spotted using thermal imaging along footpaths in the woods and along a nearby railroad track, apparently searching for individuals who may have left the truck.,Monday was a particularly hot day in San Antonio, with temperatures reaching 101 F around 3pm, according to Weather Underground. The truck was found in a secluded area of San Antonio. It was initially reported that 25 individuals in the trailer were dead, but that number has quickly risen. It is expected that the number will continue to rise, with some suggesting it could exceed 50. An investigation is underway.,The truck was discovered sometime before 7 p.m. (CDT).,About 20 Migrants Died While Trying to Enter Spanish City of Melilla - Source25 June, 02:35 GMT,Texas Governor Greg Abbott blamed President Biden for the deaths. “These deaths are on Biden.” The Republican Governor wrote on Twitter “They are a result of his deadly open border policies.”,At Least 42 People Found Dead Inside Truck Carrying Migrants In Texas.

C | 胡敏指出，目前相关研究仅证实晚餐高钾摄入与睡眠改善存在相关性，而非直接因果关系。
D | 简单来说，高钾晚餐是辅助改善睡眠的方式，绝非治疗失眠的“良方”，更不能替代药物治疗、规律作息等常规睡眠调节手段，失眠人群切勿盲目依赖该方式。 高钾饮食减的是水分而非脂肪 除了助眠，“高钾晚餐能快速减脂”的说法更是戳中众多减脂人群的需求，成为其火爆出圈的核心原因。对此，胡敏表示，高钾饮食确实能让体重短期下降，但这种“瘦身效果”存在明显误区，并非真正减脂。 胡敏解释，人体体重短期波动，大多与水分潴留相关。钾元素可以有效促进身体排出多余的钠，缓解身体水肿、排出潴留水分，这也是食用高钾食物后体重快速下降的核心原因，减掉的只是水分，并非脂肪。同时，菠菜、山药、豆类等多数高钾食物富含膳食纤维，饱腹感极强，能自然减少全天总热量摄入，且钾可提升人体运动耐力，帮助消耗更多热量。 需要明确的是，高钾食物本身不含任何可直接分解脂肪的成分。想要实现真正减脂，依旧需要依靠合理的饮食控制、规律运动。
E | 高钾饮食只能作为辅助方式，无法替代科学的减脂方案，盲目跟风单一饮食反而可能影响身体健康。 四类人群盲目补钾暗藏健康风险 在网络热潮下，不少健康人群跟风坚持高钾晚餐，甚至额外服用补钾制剂。对此，胡敏强调，钾元素摄入讲究“按需补充”，绝大多数健康成年人依靠日常均衡饮食，即可满足身体钾元素需求，无需刻意食补，更不用药补。 临床中仅四类人群适合在专业指导下适当补钾：确诊低钾血症患者;严重腹泻呕吐、长期服用排钾利尿剂等钾流失过多人群;高温作业、高强度运动等钾消耗增加人群;长期厌食、节食、挑食且肾功能正常的摄入不足人群。且补钾需遵循科学原则，轻度缺钾、肾功能正常者优先食补，药物补钾必须遵医嘱并监测电解质。 与此同时，四类人群严禁盲目补钾，否则会引发严重健康隐患，包括确诊高钾血症患者、急慢性肾功能不全少尿或无尿人群、服用保钾类降压药等药物人群、Addison病患者。普通人盲目过量补钾，轻则出现手脚麻木、肌肉无力、恶心呕吐等不适，重则引发心律失常、心脏骤停等致命风险，其中肾功能不全人群补钾风险最高，务必杜绝自行进补。 胡敏提醒，健康饮食的核心是均衡多样，无需跟风追捧网红饮食。日常三餐合理搭配食材、规律作息、适度运动，才是兼顾睡眠、体重管理与身体健康的根本方式。
