一個雞蛋到底含有多少蛋白質(zhì)呢

Eating eggs for breakfast is a great way to jump-start your day. That's because eggs are high in protein and have been linked to a number of important health benefits. But exactly how much protein does one egg contain?

早餐吃雞蛋是開啟一天的好方法。這是因為雞蛋富含蛋白質(zhì)，并與許多重要的健康益處有關(guān)。但是一個雞蛋到底含有多少蛋白質(zhì)呢?

The average egg contains around 6 to 7 grams of protein each, but the precise amount of protein in a single egg can vary depending on the size of the egg (via Healthline). For example, a small egg contains around 4.9 grams of protein, while a jumbo egg contains 8.2 grams of protein.

每個雞蛋平均含有6-7克蛋白質(zhì)，但每個雞蛋中蛋白質(zhì)的精確含量會根據(jù)雞蛋的大小而有所不同。例如，一個小雞蛋大約含有4.9克蛋白質(zhì)，而一個大雞蛋含有8.2克蛋白質(zhì)。

Although egg whites tend to get all the credit when it comes to protein content, egg yolks also contain a decent amount of protein. In fact, egg whites only contain slightly more protein than the yolk by just 1 gram. In an egg containing 7 grams of protein, 3 of those grams come from the yolk, and the white of the egg is responsible for the other 4 grams. Egg yolks also contain most of an egg's fat and nutrients.

雖然蛋白是蛋白質(zhì)含量的主要來源，但蛋黃也含有相當數(shù)量的蛋白質(zhì)。事實上，蛋清所含的蛋白質(zhì)僅比蛋黃多1克。一個含有7克蛋白質(zhì)的雞蛋，其中3克來自蛋黃，其余4克來自蛋清。蛋黃還含有雞蛋的大部分脂肪和營養(yǎng)物質(zhì)。

In addition to being a great source of protein, eggs are full of vitamins and nutrients that can provide numerous health benefits. For instance, eggs have been shown to help improve brain function (via Good Housekeeping). That's because they're high in choline, an essential nutrient that your brain needs in order to regulate memory, mood, and muscle control. Getting enough choline in your diet may help prevent the onset of dementia and other cognitive impairments.

雞蛋不僅是蛋白質(zhì)的重要來源，還富含維生素和營養(yǎng)物質(zhì)，對健康有很多好處。例如，雞蛋已被證明有助于改善大腦功能。這是因為它們富含膽堿---- 一種大腦調(diào)節(jié)記憶、情緒和肌肉控制所需的必需營養(yǎng)素。在飲食中攝取足夠的膽堿可以幫助預防癡呆和其他認知損傷的發(fā)生。

Eggs can also promote eye health. Eggs are full of carotenoids like lutein and zeaxanthin, which give egg yolks their yellow pigment. Studies have shown that lutein and zeaxanthin can also impact eye health by preventing age-related vision loss and the formation of cataracts. In addition, eating eggs can help support bone health. Eggs contain a decent amount of vitamin D, which can help increase the absorption of calcium, and both calcium and vitamin D can help build stronger bones.

雞蛋還可以促進眼睛健康。雞蛋富含類胡蘿卜素，如葉黃素和玉米黃質(zhì)，這些物質(zhì)使蛋黃呈現(xiàn)黃色。研究表明，葉黃素和玉米黃質(zhì)還可以通過預防與年齡相關(guān)的視力下降和白內(nèi)障的形成來影響眼睛健康。此外，吃雞蛋有助于骨骼健康。雞蛋含有適量的維生素D，有助于增加鈣的吸收，鈣和維生素D都有助于強健骨骼。
