7克橄榄油帶來的改變

橄榄油,屬木本植物油,是由新鮮的油橄榄果實直接冷榨而成的,不經加熱和化學處理,保留了天然營養成分,橄榄油被認為是迄今所發現的油脂中最适合人體營養的油脂。

橄榄油和橄榄果渣油在地中海沿岸國家有幾千年的曆史,在西方被譽為“液體黃金”,“植物油皇後”,“地中海甘露”, 原因就在于其極佳的天然保健功效,美容功效和理想的烹調用途,可供食用的高檔橄榄油是用初熟或成熟的油橄榄鮮果通過實體冷壓榨工藝提取的天然果油汁,是世界上以自然狀态的形式供人類食用的木本植物油之一。

橄榄油是從橄榄(橄榄樹的果實)中提取的天然油,油中約14%是飽和脂肪,而11%是多不飽和脂肪,例如omega-6和omega-3脂肪酸。

橄榄油具有多種健康價值,其中包括:具有極強的抗發炎活性,減少心血管疾病風險和中風風險,降低癌症風險,降低糖尿病風險。

既往研究發現,那些每天食用超過半湯匙橄榄油的人罹患任何心血管疾病的風險降低15%,而患冠心病的風險降低21%。用等量的橄榄油代替一茶匙的黃油,人造黃油,蛋黃醬或乳制品脂肪,可使心血管疾病的風險降低5%,使冠心病的風險降低7%。

2024年5月的最新研究Consumption of Olive Oil and Diet Quality and Risk of Dementia-Related Death表明,與從不或很少食用橄榄油的人相比,每天食用至少7克橄榄油與癡呆症相關死亡風險降低28%有關。

研究表明,無論飲食品質如何,較高的橄榄油攝入量與較低的癡呆相關死亡率風險相關。

在 92383 名參與者中,60582 名 (65.6%) 是女性,平均 (SD) 年齡為 56.4 (8.0) 歲。在 28 年的随訪期間(2183095 人年),發生了 4751 例與癡呆症相關的死亡。載脂蛋白 ε4 (APOE ε4) 等位基因純合的個體死于癡呆症的可能性高出 5 至 9 倍。與從不或很少食用橄榄油相比,每天食用至少 7 克橄榄油可使癡呆相關死亡風險降低 28%(調整後的彙總 HR,0.72 [95% CI,0.64-0.81])(P 為趨勢 < .001);進一步調整 APOE ε4 後結果一緻。沒有發現飲食品質評分之間存在互動作用。在模拟替代分析中,用等量的橄榄油替代 5 克/天的人造黃油和蛋黃醬,與 8%(95% CI,4%-12%)至 14%(95% CI,7%-20)降低癡呆症死亡風險相關。其他植物油或黃油的替代品并不顯著。

既往多項臨床試驗支援橄榄油通過改善内皮功能、凝血、脂質代謝、氧化應激、血小闆聚集和減少發炎來減少 CVD 的作用。來自動物和人類研究的機制證據表明,橄榄油中的酚類化合物尤其是特級初榨橄榄油,可以減輕發炎、氧化應激并恢複血腦屏障功能,進而減少大腦澱粉樣蛋白-β和 tau 相關的病理并改善認知功能。

好油還得選橄榄油!
