雞蛋營養知多點
中國人傳統習俗生日會吃紅雞蛋，從前的人會用花紅粉為雞蛋染色，但花紅粉為工業用色素不利健康，所以現在改用紅色食用色素，或者用紅色玻璃紙包裹。雞蛋是一種老少咸宜的食材，從中醫角度來看它屬性平和，有滋陰潤燥、養血安胎及健腦的功效，但怎樣吃才是最好？來看看以下Q&A能否解決你對雞蛋的疑問。
雞蛋 — 性平，有滋陰潤燥，養血安胎及健腦，適合體質虛弱、營養不良、氣血不足、產婦、孕婦等。蛋黃能健腦益智，增強記憶力，適合嬰兒及小兒適量食用。注意發燒及腹瀉不宜。
問：一天只可吃一隻雞蛋？
答：答案是要視乎你的飲食模式，如果平日已經多吃蛋白質類食物，例如魚、肉、豆製品等，一天一隻雞蛋已經足夠；相反如果不多吃蛋白質類食物，則可以多吃蛋來補充營養。
問：聽說蛋黃膽固醇很高，只吃蛋白更健康嗎？
答：近年醫學界指從飲食中攝取的膽固醇，並不是導致人體血液膽固醇 增加 的主要因素，預防膽固醇增加應注意減少飽和脂肪和反式脂肪的攝取量。而蛋黃中含有許多營養素是蛋白沒有的，例如Omega-3、鐵、鋅、葉酸等，所以不要嫌棄蛋黃啊！
問：雞蛋哪種食法最好？
答：全熟烚蛋最好，因為生雞蛋含有抗生物素蛋白(avidin)令身體難以消化及吸收蛋白質，當雞蛋煮熟後蛋白結構會變化，蛋白質會易於被吸收，吃烚蛋我們可以吸收到雞蛋的蛋白質九成以上，但吃生蛋只可以吸收三至五成。而雞蛋中可能存在沙門氏菌，食用未完全煮熟的雞蛋例如溫泉蛋、溏心蛋等，會有感染沙門氏菌的風險，所以嬰幼兒、長者或抵抗力較差者宜吃全熟蛋。

Learn more about nutrients in eggs
According to the Chinese tradition, individuals who celebrate their birthday will eat eggs that have been dyed red. In the past, people would dye the eggs with Rhodamine B, but it was not a healthy option because it is an industrial chemical. Nowadays people would dye the eggs with food coloring or just wrap it with red glass paper.
Eggs are suitable for both young and old to consume. From the perspective of Chinese Medicine, it is mild in nature, can nourish the yin and moisten the body, nourish the blood, improve the wellbeing of the fetus, and strengthen the brain. How should we prepare eggs to enjoy its greatest benefits? Let us look at the Q&A below to see if they can answer your questions.
Q: Can we eat more than one egg a day?
A: Depends on your diet. If you have consumed a lot of protein-based food like fish, meat and soy products, then one egg is enough; if there is a lack of protein in your diet, you can replenish it by taking more eggs.
Q: I heard the cholesterol in the yolk is very high, should we just eat the egg white?
A: According to recent medical studies, the cholesterol we consume through food is not the main contributor of the cholesterol in our blood. In order to prevent the cholesterol levels from rising, we need to monitor the consumption of foods that contain saturated and trans fat. Egg yolk, on the other hand, contains a lot of nutrients that are not found in the egg white, for instance, Omega-3, iron, zinc, and folic acid. So do not toss the egg yolk away!
Q: What is the best way to cook eggs?
A: Fully cooked eggs are the best because the raw ones contain avidin, which is hard to digest and to absorb the protein. When the eggs are cooked, the structure of the egg white will change, making it easier for the body to absorb. Our body can absorb at least 90% of the protein if they are completely boiled, but it can only absorb 30%-50% if the eggs are still raw. Moreover, eggs might contain salmonella, so we might risk getting an infection if we eat soft-boiled eggs and poached eggs that are not fully cooked. Therefore, toddlers and elders with a weak immune system are encouraged to consume eggs that are fully cooked.
