Beans and Soy Products Linked to Lower Blood Pressure Risk, Study Finds

Quick Look

  • A recent study suggests that consuming beans and soy products may significantly reduce the risk of high blood pressure.
  • Researchers found that higher intake of these foods was associated with a 16-19% lower risk, with potential reductions up to 30%.

AI-generated summary

Why It Matters

A recent international study analyzed 12 prospective cohort studies across the US, Europe, and Asia, focusing on the relationship between bean and soy product consumption and the risk of high blood pressure. The findings suggest a significant reduction in hypertension risk with increased intake of these foods.

降血壓不只靠戒鹽,日常飲食中常見的豆類與大豆食品,也可能與控制高血壓風險有關。食農專家韋恩表示,近期1篇國外研究指出,攝取豆類或大豆食品的受試者,罹患高血壓風險分別下降16%、19%,拉高攝取量後,降幅最高甚至可達近3成。研究也計算出每天攝取豆類約170克、大豆食品約60-80克,就能達到最佳效果。

韋恩於臉書粉專「韋恩的食農生活」與網頁發文表示,豆漿、豆腐、毛豆這些台灣餐桌上隨手可得的食材,可能是控制血壓最被低估的工具。1篇發表於《BMJ Nutrition, Prevention & Health》的大型統合分析,整理了橫跨美國、歐洲與亞洲的12個前瞻性世代研究,發現攝取最多豆類的人,罹患高血壓的風險低16%,攝取最多大豆食品的人則低19%,攝取量拉高之後,降幅最高達到近30%。

此外,研究也算出有效攝取量。豆類每天大約攝取170克時,達到最大效果;大豆食品則是每天吃60-80 克。若換算成份量,100克大約是1杯煮熟的豆子,或1個掌心大小的豆腐。

豆類食物有助降血壓3機制

豆類和大豆為什麼能降血壓?對此,韋恩說,研究團隊提出3個機制,包括:

●礦物質與纖維:豆類富含鉀、鎂與膳食纖維,這3種營養素本來就和健康的血壓調節有關,鉀能幫助身體排出多餘的鈉,鎂與血管平滑肌的放鬆有關。

●腸道菌產物:豆類與大豆的可溶性纖維進入腸道後,會被腸道菌發酵產生短鏈脂肪酸,這些代謝產物可能幫助血管放鬆、擴張,讓血壓下降。

●大豆特有成分:大豆食品含有大豆異黃酮,這類植化素本身就被認為和較低的血壓有關。這也是為什麼大豆食品的降幅達19%,比一般豆類的 16% 再高一些。

痛風患者適量攝取無礙健康

不過,很多人一聽到豆類就想到普林和痛風,也會刻意避開豆腐豆漿。韋恩說明,其實植物性普林與痛風發作的關聯,和紅肉、海鮮並不相同,並沒有提高痛風風險,痛風患者適量吃大豆食品其實沒有問題。

韋恩強調,對台灣人而言,這項研究的實用價值在於門檻很低。一杯無糖豆漿、一盒板豆腐、一把毛豆,就能輕鬆達到研究觀察到有效果的攝取量。對於有高血壓困擾或想預防的人來說,把每天攝取的一部分蛋白質換成豆製品,也是成本最低的飲食調整之一。
