文章一：Eggs Support Muscle
Egg protein is an excellent source of all the essential amino acids your body needs and is easy to digest. Thus, eggs are effective for building muscle and preventing loss, especially as we age. In fact, eggs are likely the most digestible protein source—measured at 97 percent, compared with many plant proteins, which are digested at 45 percent to 80 percent. Eggs are also very high in leucine, an amino acid considered to be the strongest stimulator of muscle growth and repair. For optimal muscle benefits, you need 700 to 3,000 milligrams of leucine daily. One egg contains about 500 milligrams, packed in just 72 calories, thus making it a great choice for muscle health. Eggs also contain other nutrients important for muscles, according to Jodi Duval, a naturopathic physician and owner of Revital Health. These include:
Choline, which helps with muscle coordination Vitamin D, important for muscle strength Vitamins B12 and B2, which support energy use in muscles Selenium, an antioxidant that helps with recovery Healthy fats, especially found in pasture-raised eggs, which contain omega-3 s that reduce muscle inflammation
Omega-3 fats improve how muscles use amino acids and help reduce inflammation, which is important because inflammation can cause muscle loss. Eggs are effective in helping to prevent muscle loss, or sarcopenia. Starting as early as age 30, adults begin to lose about 8 percent of their muscle mass each decade, a rate that accelerates after age 70.
1. 根據本文，何者敘述錯誤？
（1）雞蛋含有豐富的維生素E。
（2）吃雞蛋可預防肌肉流失。
（3）一顆雞蛋熱量約有72卡。
（4）雞蛋是所有蛋白質來源最容易消化的一種。
2. 根據本文，成年人從幾歲肌肉就會開始流失，流失的比率為何？
3. 閱讀完本文後，有哪些地方讓你對雞蛋改觀？理由是？
解答：
1.（1）
2. Starting as early as age 30, adults begin to lose about 8 percent of their muscle mass each decade, a rate that accelerates after age 70.
（從30歲開始，成年人每十年就會失去約8%的肌肉量，70歲過後流失更快。）

Egg protein is an excellent source of all the essential amino acids your body needs and is easy to digest。（123RF）文章二：How Many Eggs?
About 20 grams of egg protein is enough to stimulate muscle growth after resistance training. Since one egg contains roughly 6 grams of protein, three eggs will get you close to the target. How much you need also depends on your goals. For athletes or those aiming to build muscle, Duval often recommends two to four eggs after a workout, along with a carbohydrate source to help replenish glycogen and support recovery. For older adults, she suggests one to two eggs earlier in the day, such as at breakfast, when protein timing is especially important to reduce muscle breakdown, regardless of activity level.
“For both athletes and older adults, consistency and spreading protein intake across the day are more important than loading it all at once, ” she said. Duval also emphasized the importance of egg quality. She always recommends pasture-raised, organic eggs when possible. “They contain more omega-3s, antioxidants, and offer a better overall nutrient profile,” she said.
1. 根據本文，下列何者有誤？
（1）年紀較大的長輩建議在早餐食用1~2顆雞蛋
（2）運動員每日建議集中攝取蛋白質
（3）來自牧場的雞蛋營養價值較高
（4）重量訓練後建議可補充3顆蛋。
2. 根據本文，為何來自牧場的有機蛋較好？
3. 閱讀完本文後，你有何感想？
解答：
1.（2）
2. They contain more omega-3s, antioxidants, and offer a better overall nutrient profile.
（它們含有更多的ω-3脂肪酸與抗氧化物質，整體提供更好的營養成分。）
