〔健康頻道/綜合報導〕40歲後想維持身材,光靠少吃、飲食清淡未必是好方法。營養師王郁菁表示,這個階段若為了控制體重,長期採取節食或以蔬菜為主的飲食,反而可能忽略身體重要的核心營養來源蛋白質,不僅影響肌肉量、代謝與體力,代謝也會變得更慢,甚至讓膠原蛋白快速流失,演變成「越減越老、越瘦越虛」。她提醒,年過40的女性更應重視每餐蛋白質攝取,並從豆、魚、蛋、肉等多元食物補充。
40+女性補蛋白質6大關鍵
王郁菁於臉書粉專「郁菁營養師」發文指出,許多人在40歲這個階段為了維持身材,會採取過於清淡的節食或只吃蔬菜餐,卻忽略人體最核心的建築材料蛋白質,不只影響代謝,可能還會導致膠原蛋白流失。她提醒,蛋白質對於身體具有以下6項重要性,不可或缺:
請繼續往下閱讀...
●維持肌肉量:40歲後肌肉量會逐漸流失,若蛋白質攝取不足,更容易出現沒力情況。
●幫助穩定代謝:蛋白質是維持代謝與身體日常修復所需的重要材料。
●增加飽足感:每餐加入足夠蛋白質,有助增加飽足感,比較不容易嘴饞。
●支持骨骼健康:中年後除了留意鈣質攝取,蛋白質也與中年後維持骨骼健康相關。
●幫助身體修復保養:皮膚、組織及身體修復,都需要充足蛋白質作為原料。
●來源要多元:蛋白質可從豆、魚、蛋、肉類等不同來源均衡攝取,重點是餐餐都要有。
日常飲食聰明補蛋白3技巧
至於日常如何補充蛋白質?王郁菁建議,可以掌握以下3個技巧,餐餐都有蛋白質,身體才有底氣:
1.早餐加杯濃豆漿:別再只吃麵包配黑咖啡,因為這只有攝取澱粉,多加一杯無糖豆漿或水煮蛋,有助啟動整天代謝。
2.每餐一掌心優質蛋白:午晚餐盤裡,至少要有一手掌大小的豆魚蛋肉類,優先選低脂白肉或植物性蛋白。
3.運動後聰明補:散步、瑜伽或重訓後30分鐘內,補充蛋白質與適量澱粉,是維持緊緻線條的關鍵時刻。

The Blood and Marrow Transplantation Society of the Republic of China warned that the bone marrow donor database is facing the impact of the declining birth rate. About 1,000 people drop out every month because they are over 55 years old, but there are less than 500 new entrants, which is less than half of the past. If "more outflows and fewer incomings" continue, it will affect the opportunities for blood cancer patients to find suitable matches. Experts call on people aged 18 to 46 to actively set up a donation profile.

Huang Xuan, a thoracic and critical care physician, pointed out that patients with cardiac arrest often experience "dying gasping", which is characterized by irregular and weird snoring mixed with grunting.

Do not misjudge the patient to be asleep and miss the golden rescue time.
