〔健康頻道/綜合報導〕提到飲食補充Omega-3,很多人可能會先想到鯖魚。不過,食農專家韋恩表示,其實鮭魚才是公認最營養的魚。他指出,鮭魚之所以在所有魚類中特別受到保健研究重視,是因為它同時含有高量的DHA(屬於Omega-3)和蝦紅素,這2種成分在其他食物裡,很難同時攝取到這麼高的濃度,攝取也有助護心、顧腦及抗氧化。
韋恩於臉書粉專「韋恩的食農生活」與網頁發文指出,DHA是大腦神經細胞膜的重要組成,佔腦部脂肪酸約97%,視網膜脂肪酸約93%,研究顯示,足量的DHA可維持神經訊號傳遞效率、減緩認知退化、降低憂鬱與失智風險。另外,對心血管的保護、抗發炎效果,也有豐富文獻支持。至於所含EPA,則對心血管特別有保護作用,可降低三酸甘油脂、改善血脂代謝。
此外。韋恩說明,蝦紅素的抗氧化能力則是另一個層次。其清除自由基的能力是維生素C的6000倍、輔酶Q10的800倍、綠茶兒茶素的560倍、維生素E的500倍,因此被稱為「超級抗氧化劑」。對於免疫系統、皮膚防紫外線損傷、眼部保護都有研究支持,近年更有臨床研究發現,蝦紅素與葉黃素搭配使用,對抗於藍光的效果具有加乘作用。
韋恩強調,鮭魚的蝦紅素主要來自它吃的磷蝦和藻類,養殖鮭魚若沒有補充蝦紅素來源,肉色會比較白、保健成分也低很多,這也是挑選鮭魚時值得注意的一個細節。
