魚頭的功效與作用
魚頭的功效與作用1、補充蛋白
魚肉中蛋白質含量豐富,其中所含必需氨基酸的量和比值最適合人體需要,因此,是人類攝入蛋白質的良好來源。
2、預防心腦血管疾病
魚肉中脂肪含量較少,而且多由不飽和脂肪酸組成,人體吸收率可達95%,具有降低膽固醇、預防心腦血管疾病的作用。
3、抗衰老、美容功效
魚頭含有豐富的硒元素,經常食用有抗衰老、養顏的功效,而且對腫瘤也有一定的防治作用;
4、滋補開胃
對於身體瘦弱、食慾不振的人來說,草魚肉嫩而不膩,可以開胃、滋補。
魚頭的營養價值
關於魚肉的營養,毋庸置疑,不管是淡水魚還是海魚,其營養成分大體相同,總的營養價值很高,而且魚肉肌纖維很短,水分含量較高,因此肉質細嫩,比畜禽的肉更易吸收。但關於魚頭的營養價值卻存在爭議:
說法一:
多吃魚頭對身體無益,魚類及大部分動物的毒素會有很多富集於頭部,而魚頭往往會有重金屬超標現象,如汞超標。所以,魚頭對於部分人來說雖是美味,但要注意少食,一切毒素都是一個積累的過程。同樣的道理,喜歡吃雞頭、鴨頭的人也得注意盡量少食。
說法二:
魚頭不僅營養豐富,味道鮮美,並含有魚肉中缺乏的卵磷脂,還有豐富的22碳6烯酸(英文縮寫DHA)。這是一種高度不飽和脂肪酸,對促進神經細胞,特別是神經傳導和神經纖維細胞生長發育極為重要,乃健腦之上品。豬、牛、羊等畜肉中DHA含量不超過10%,而魚頭遠遠高出此水平,尤其是魚眼,堪稱DHA的富礦。日本研究人員測定發現,金槍魚和鰹魚的眼窩脂肪中DHA的含量高達30%-40%,沙丁魚和竹莢魚高達70%,對兒童、青少年以及腦力勞動者特別有益。魚頭內的鋅和鐵微量元素較高,這些微量元素對大腦確有天然的滋補作用。
