營養師教芋頭正確吃法:主食選擇需配合蛋白質蔬菜並避免油炸

Quick Look

營養師謝宜芳指出芋頭屬於全穀雜糧類主食,富含膳食纖維與抗性澱粉,但仍會升高血糖,建議以蒸煮燉取代油炸、搭配蛋白質與蔬菜、適量減少其他主食,並提醒糖尿病、減重及高三酸甘油脂者需控制總碳水化合物攝取,同時強調芋頭必須充分煮熟以避免草酸鈣晶體刺激。

Why It Matters

芋頭為台灣秋冬盛產作物,常被誤認為蔬菜或僅用於甜點,實際含澱粉且屬全穀雜糧類,需正確理解其營養特性與食用方式。

〔健康頻道/綜合報導〕芋頭盛產季到了,它不只是甜點食材,富含膳食纖維。營養師謝宜芳指出,芋頭屬於全穀雜糧類、抗性澱粉的主食選擇,不能當蔬菜吃,吃多仍會升高血糖,掌握3大原則:以芋頭取代部分白飯、以蒸煮燉取代油炸、搭配蛋白質與蔬菜,並且一定要充分煮熟。她提醒,糖尿病、減重及三酸甘油脂偏高者等3族群,更要注意整餐碳水化合物總量。

謝宜芳在臉書專頁「謝宜芳老師的營養教室」發文分享,秋冬看到一顆顆香鬆綿密的芋頭,很多人第一個想到的是芋頭酥、芋泥、芋頭西米露。如果把芋頭只當成甜點材料,其實有點可惜。她整理近年10篇芋頭相關PubMed文獻後發現,芋頭是澱粉,但它多了膳食纖維、抗性澱粉、黏液質、非澱粉多醣,以及多種植物活性成分。所以,用對方法吃芋頭是不錯的主食選擇。

請繼續往下閱讀...

謝宜芳歸納芋頭的4大特色如下:

●澱粉含量高:和米飯一樣是主食,不是蔬菜,屬於全穀雜糧類,健康的吃法是有吃芋頭則飯、麵、麵包就跟著減少。尤其是糖尿病、減重或三酸甘油脂偏高的人,更重要的是控制整餐總碳水化合物,不能因為芋頭天然、有纖維,就過量地食用。

●含抗性澱粉:部分抗性澱粉不會在小腸完全消化,可進入大腸供腸道菌利用;烹煮後冷卻可能增加抗性澱粉。但份量超過還是會升高血糖。

●富含黏液質與非澱粉多醣:具有吸水、保水及膨潤等特性,相關研究正在探討其抗氧化、脂質代謝、免疫調節與益生元潛力。

●含多種植物活性物質:包括多酚、類黃酮、花青素及植物固醇等,目前細胞與動物研究確實發現部分芋頭成分具有抗氧化、抗發炎、免疫調節,甚至抗腫瘤研究潛力。不過這都是在實驗室中有抗腫瘤活性,不等於吃芋頭可以抗癌。

芋頭健康吃3大原則

芋頭到底怎麼吃最好?謝宜芳推荐,用傳統的蒸、煮、燉等方式較健康。她分享以下3大原則供民眾參考:

1.蒸、煮、燉取代油炸,搭配蛋白質與蔬菜

「蒸芋頭+青菜+魚或豆腐」,就是很完整的一餐,芋頭提供主食,魚、蛋、豆腐提供蛋白質,再搭配半盤以上蔬菜。芋頭也適合搭配肉類蒸煮,減少油脂攝取。

2.芋頭一定要煮熟

芋頭含有針狀的草酸鈣結晶(raphides)。研究進一步發現,這些針晶周圍還可能帶有 profilin 等相關蛋白。因此,生芋頭或沒有充分煮熟時,可能出現嘴巴刺、舌頭麻、喉嚨癢、疼痛或刺激感。芋頭最重要的食安原則是,不要生吃,也不要吃半生不熟的芋頭。

3.小心炸芋丸、芋泥球、芋頭西米露、芋頭蛋糕

真正需要少吃的,常常不是芋頭本身。芋頭+大量糖+油脂+精製澱粉做成的芋頭酥、炸芋丸、芋泥球、芋頭西米露、芋頭蛋糕、芋泥奶油麵包等,屬於成高糖、高脂、高熱量甜點,民眾務必慎食。

謝宜芳提醒,芋頭的鉀含量相對較高,對一般健康成人不是問題,但如果有晚期慢性腎臟病、高血鉀,或正在執行限鉀飲食,份量就應依血鉀及整日飲食計畫個別調整。

Nutritionist shares 4-legged animal test to initially observe the cognitive function of the elderly

Nutritionist Xu Cijia pointed out that asking elders to name more than 12 kinds of four-legged animals in one minute is a passing standard for cognitive function. However, failure to meet the standard does not mean dementia. He emphasized that there are four warning signs such as repeated forgetting, cooking mistakes, getting lost easily, and deterioration of judgment, which require medical treatment. He also provided five major brain protection principles to reduce the risk of dementia.

The results of the national centralized procurement of dental medical consumables are released: sky-high price of dental implants is becoming inclusive, and the procurement work has started.

The national centralized procurement results conference for dental medical consumables was held in Sichuan. Since the full implementation of centralized procurement in 2023, the average price of a single dental implant has dropped from 15,000 yuan to 6,000-7,000 yuan, and the number of dental implant surgery services in public hospitals has increased by 71% annually. On September 28, Sichuan and Shaanxi provinces took the lead in launching continuous procurement work.
