\u003c/p>\u003cp>研究團隊從《中國健康與營養調查》中納入了12177名成年人的數據,通過每周隨機3次、連續24小時的飲食回顧,評估了受試者的日常飲食情況,并使用中國食品成分表計算營養素攝入量。依據受試者每天的碳水化合物攝入量占比,將人群分為7組(<35%、35%~<45%、45%~<50%、50%~<55%、55%~<60%、60%~<70%和≥70%),隨后通過6年隨訪調查,共發現4269人出現高血壓,總碳水化合物攝入量占比與新發高血壓之間呈U型關聯,碳水化合物攝入量占比為50%~55%時,新發高血壓風險最低;高質量碳水化合物攝入量占比越低,或低質量碳水化合物攝入量占比越高,新發高血壓風險越高;低質量植物性碳水化合物攝入量占比越低,新發高血壓風險越低。\u003c/p>\u003cp>為了讓患者更好地了解高/低質量碳水化合物,研究團隊進行了分類。高質量碳水化合物包括全谷類、水果、豆類、非淀粉類蔬菜;低質量碳水化合物包括細糧、淀粉類蔬菜、添加糖類和100%果汁等。(胡學敏)\u003c/p>","type":"text"}],"currentPage":0,"pageSize":1},"editorName":"杜毅楠"},"__env__":"production"};

    要想血壓好,碳水不多也不少

    原標題:要想血壓好,碳水不多也不少

    飲食習慣是影響高血壓發病的重要因素,但迄今為止,很少有研究評估碳水化合物攝入量與高血壓風險的關系。為彌補此空白,中國南方醫科大學南方醫院開展了一項新研究,發現攝入碳水化合物過多過少都會增加血壓升高的風險。

    要想血壓好,碳水不多也不少

    研究團隊從《中國健康與營養調查》中納入了12177名成年人的數據,通過每周隨機3次、連續24小時的飲食回顧,評估了受試者的日常飲食情況,并使用中國食品成分表計算營養素攝入量。依據受試者每天的碳水化合物攝入量占比,將人群分為7組(<35%、35%~<45%、45%~<50%、50%~<55%、55%~<60%、60%~<70%和≥70%),隨后通過6年隨訪調查,共發現4269人出現高血壓,總碳水化合物攝入量占比與新發高血壓之間呈U型關聯,碳水化合物攝入量占比為50%~55%時,新發高血壓風險最低;高質量碳水化合物攝入量占比越低,或低質量碳水化合物攝入量占比越高,新發高血壓風險越高;低質量植物性碳水化合物攝入量占比越低,新發高血壓風險越低。

    為了讓患者更好地了解高/低質量碳水化合物,研究團隊進行了分類。高質量碳水化合物包括全谷類、水果、豆類、非淀粉類蔬菜;低質量碳水化合物包括細糧、淀粉類蔬菜、添加糖類和100%果汁等。(胡學敏)
