脂肪對人體的五大好處

每次在吃東西的時候,常常都不知道吃什麼?又怕鹹怕油膩,各種不同的飲食建議圍繞在我們的腦袋中,你甚至不知道該怎麼選擇你的食物。
以脂肪為例,多年來,它已經被描繪成邪惡的怪物和高膽固醇,是心血管疾病與肥胖的根本原因。但科學研究表明,現在吃更多的脂肪有很多好處,我們應該好好的再思考我們的飲食習慣。

以脂肪為例,多年來,它已經被描繪成邪惡的怪物和高膽固醇,是心血管疾病與肥胖的根本原因。但科學研究表明,現在吃更多的脂肪有很多好處,我們應該好好的再思考我們的飲食習慣。

總之,脂肪已經臭名遠播了!

在 Grain Brain 的 David Perlmutter 博士介紹,如果和以前的人飲食相比,他們的飲食為75%的脂肪,20%的蛋白質,5%的碳水化合物。而我們目前的狀況為20%的脂肪,20%的蛋白質,60%的碳水化合物,David Perlmutter 博士解釋,現今的疾病,包含老年痴呆症、過動症、憂鬱、焦慮和慢性頭痛,都是身體和大腦由碳水化合物引發的炎症。

其他的研究告訴我們,肥胖的流行,在這過去的50年中增加了一倍,不是因為我們吃了太多的脂肪,而是因為我們吸收了太多的碳水化合物跟糖,包含在水果與果汁裡面的葡萄糖。

Gary Taubes在他的文章「為什麼我們發胖」表示,如果世界上從來沒有發明香菸,肺癌就會是罕見疾病。同樣我們沒有吃這麼多的高碳水化合物食物,肥胖會是一種罕見疾病。

脂肪被認定為肥胖的罪魁禍首。事實上對人體是有許多好處的,

脂肪對於大腦健康是不可或缺的重要角色

你知道嗎?腦組織有將近60%的脂肪,低脂肪的飲食實際上剝奪大腦所需要的養分。
這不只是在談論必需脂肪酸(Essential fatty acid)以及不飽和脂肪酸(OMEGA-3),

人體必需的維生素A、D、E和K是不溶於水,需要依賴脂肪的運輸使身體能夠吸收,這些維生素是大腦與許多身體器官健康的重要關鍵。

維生素D目前被廣泛吹捧為可以減少阿茲海默症、帕金森氏症、憂鬱症和其他腦部疾病,OMEGA-3被認為可以提高認知功能,以及改善你的心情。

脂肪讓你的肺部正常工作

我們的肺覆蓋一層飽和脂肪組成的物質,像早產兒如果缺乏這層物質,會使用一種『表面活性劑(surfactant)』,以幫助保持他們的肺部正常運作。

如果沒有足夠的飽和脂肪,我們的肺可能會受到影響。
目前一些研究正在尋找飽和脂肪跟氣喘之間的關聯性。

脂肪可以增強你的免疫系統

Michael博士和Mary 博士在他們 Good Calories, Bad Calories一書中提到,奶油跟椰子油裡面的飽和脂肪影響著免疫系統的健康。

如果缺乏了足夠的飽和脂肪酸,會阻礙白血球細胞的運作,使白血球細胞無法辨識外來入侵者(如病毒、細菌)

脂肪影響你最大的器官健康

脂肪組成大部份的細胞膜,而我們的皮膚是由大量的細胞組成,
沒有消耗脂肪的話,我們的皮膚會變得乾燥龜裂,也容易感染病菌。

脂肪對心臟有好處

雖然在過去,脂肪一直被告知要減少攝取,但許多研究已經證明進食飽和脂肪的好處。
一個特別的研究,主要研究在太平洋群島的居民,他們的飲食為60%的飽和椰子油,結果幾乎居民沒有心臟疾病。

此外,脂肪比起碳水化合物,提供兩倍的卡路里能量(脂肪9克vs碳水化合物4克),因此,不僅會維持你的能量更長時間,使身體感到滿足,也有助於你吃得更少。

但,要遠離反式脂肪,它是透過氫原子以飽和脂肪在加熱過程期間製作出來的真的邪惡怪物

所以,抓一把核桃,享受一塊鮭魚、橄欖油、奶油製成的三明治,加一點椰子油到你早晨的飲料。從今天開始,轉移你的飲食習慣,並讓那些好的脂肪回到你的身體裡面。
