How Healthy Are Eggs?

From: The New York Times

To many nutrition experts, eggs are golden — one of the most accessible and affordable protein sources available.

And while the “affordable” part may currently be up for debate as bird flu drives up the prices, experts point out that eggs are still cheaper than many lean meats and fresh fish.

Plus, they're versatile, portable (when hard-boiled) and an easy lift for anyone new to cooking.

They're high in cholesterol — but not the kind that harms your health.

When Dr. Martha Gulati, the director of preventive cardiology at the Cedars-Sinai Smidt Heart Institute, sees patients with high cholesterol, they often ask, “Can I eat eggs?”

It's a fair question. One egg contains 207 milligrams of dietary cholesterol, which is about three times more than you'd get from a sausage link.

But the cholesterol in eggs probably won't increase your risk of heart attack and stroke. That's because dietary cholesterol and blood cholesterol aren't the same, Dr. Gulati said. Blood cholesterol — specifically low-density lipoprotein, or LDL — is what causes the dangerous plaque accumulation in your arteries and veins.

Some blood cholesterol comes from dietary cholesterol, but far more comes from your own liver, she said. Your liver makes more LDL when you eat excess saturated fat. But eggs (unlike sausages) aren't very fatty. One egg contains just 1.6 grams of saturated fat.

They're a complete protein source.

One egg contains more than six grams of protein, which nutrition experts consider high, relative to its 70 total calories.

The quality of an egg's protein is also a key benefit, said Sapna Batheja, a dietitian and assistant professor of food and nutrition at George Mason University.

Proteins — the building blocks of your body — are all made of various combinations of 20 amino acids. Your body can make 11 of these amino acids itself, but you must get the other nine from food, Dr. Batheja said. Eggs contain all nine, making them a “complete” protein source.

They're rich in choline.

Eggs are one of the highest sources of the multitasking nutrient choline, which is important for your muscle control, metabolism, nervous system, mood and memory, among other things.

Your body can make some choline on its own, but not as much as it needs, said Razan Hallak, a dietitian at Ohio State University Wexner Medical Center.

One egg contains 169 milligrams of choline, which means two eggs could put you well on your way to meeting the daily recommendation of 550 milligrams for adult males and 425 milligrams for females.

Serious choline deficiency is rare in the general public, but most people who are pregnant or nursing don't get enough. The nutrient plays a role in maintaining and creating healthy cells, Dr. Batheja said, and it's important for early brain development.

How Healthy Are Eggs?

From: The New York Times

To many nutrition experts, eggs are golden — one of the most accessible and affordable protein sources available.

在许多营养专家心目中，鸡蛋价值连城——它们是最容易获得、最经济实惠的蛋白质来源之一。

nutrition /njuːˈtrɪʃ.ən/ 表示“营养物质；营养，滋养；营养学”，英文解释为“the substances that you take into your body as food and the way that they influence your health”举个🌰：Good nutrition is essential if patients are to make a quick recovery. 病人如果要迅速康复，必须补足营养。

protein /ˈprəʊ.tiːn/ 表示“蛋白质”，英文解释为“one of the many substances found in food such as meat, cheese, fish, or eggs, that is necessary for the body to grow and be strong”

And while the “affordable” part may currently be up for debate as bird flu drives up the prices, experts point out that eggs are still cheaper than many lean meats and fresh fish.

由于禽流感推高了价格，“经济实惠”这一点目前可能存在争议，但专家指出，鸡蛋仍然比许多瘦肉和鲜鱼便宜。

lean /liːn/ 作动词，表示“（使）倾斜，（使）向一侧歪斜”，英文解释为“to (cause to) slope in one direction, or to move the top part of the body in a particular direction”举个🌰：She leaned forward and whispered something in my ear. 她俯身过来和我耳语了几句。

lean作形容词，表示“肉少的；瘦且健康的”，英文解释为“without much flesh; thin and fit”如：a lean, muscular body 清瘦而肌肉发达的身体。

lean on sb/sth 表示“依靠，凭借”，英文解释为“to use someone or something to help you, especially in a difficult situation”举个🌰：He's always had his big brother to lean on. 他总是依靠他大哥。

Plus, they're versatile, portable (when hard-boiled) and an easy lift for anyone new to cooking.

此外，它们用途广泛，便于携带（煮熟后），对于烹饪新手来说也很容易上手。

versatile /ˈvɜːsəˌtaɪl/ 表示“多才多艺的；有多种用途的，多功能的，万用的”，英文解释为“able to change easily from one activity to another or able to be used for many different purposes”举个🌰：Never before has computing been so versatile. 计算机技术从未像现在这样用途广泛。

hard-boiled /ˌhɑːdˈbɔɪld/ 1）表示“（蛋）煮得老的”，英文解释为“A hard-boiled egg has been heated in its shell in boiling water until both the white and yellow parts are solid.”

2）表示“（人）冷酷的，不动感情的”，英文解释为“used to describe a typical character from this style of story, who is strong and determined and shows little emotion”

They're high in cholesterol — but not the kind that harms your health.

鸡蛋的胆固醇含量很高，但不会危害健康。

cholesterol /kə'lɛstərɔl/ 表示“胆固醇”，英文解释为“Cholesterol is a substance that exists in the fat, tissues, and blood of all animals. Too much cholesterol in a person's blood can cause heart disease.”如：a dangerously high cholesterol level. 危险的高胆固醇水平。

When Dr. Martha Gulati, the director of preventive cardiology at the Cedars-Sinai Smidt Heart Institute, sees patients with high cholesterol, they often ask, “Can I eat eggs?”

西达斯-西奈的斯密特心脏病研究所预防心脏病学主任玛莎·古拉蒂在接诊时经常会有高胆固醇患者问：“我能吃鸡蛋吗？”

cardiology /ˌkɑː.diˈɒl.ə.dʒi/ 表示“心脏病学”，英文解释为“the study and treatment of medical conditions of the heart”

It's a fair question. One egg contains 207 milligrams of dietary cholesterol, which is about three times more than you'd get from a sausage link.

这是个好问题。一个鸡蛋内含有207毫克的膳食胆固醇，是香肠串的胆固醇含量的大概三倍。

dietary /ˈdaɪ.ə.tər.i/ 表示“饮食的”，英文解释为“relating to your diet”举个🌰：Dietary habits can be very difficult to change. 饮食习惯很难改变。

But the cholesterol in eggs probably won't increase your risk of heart attack and stroke. That's because dietary cholesterol and blood cholesterol aren't the same, Dr. Gulati said. Blood cholesterol — specifically low-density lipoprotein, or LDL — is what causes the dangerous plaque accumulation in your arteries and veins.

但是鸡蛋中的胆固醇很可能不会增加罹患心脏病和中风的风险。古拉蒂说，这是因为膳食胆固醇和血液胆固醇是不一样的。血液中的胆固醇，特别是低密度脂蛋白(LDL)，是导致动脉和静脉中危险斑块堆积的原因。

stroke /strəʊk/ 表示“中风”，英文解释为“a sudden change in the blood supply to a part of the brain, sometimes causing a loss of the ability to move particular parts of the body”举个🌰：She suffered/had a stroke that left her unable to speak. 她中风了，不能开口说话。

plaque /plɑːk/ 1）表示“铭牌；匾牌”，英文解释为“a flat piece of metal, stone, wood, or plastic with writing on it that is attached to a wall, door, or other object”举个🌰：There was a brass plaque outside the door listing the various dentists' names. 门外有一块铜牌，上面列着各位牙科医生的名字。

2）表示“齿菌斑，牙斑”，英文解释为“a plaque on the wall of a house that shows that someone famous once lived there”

在医学领域，plaque指动脉血管内壁因脂肪、胆固醇等物质沉积形成的斑块，是动脉粥样硬化的主要病理特征。这种斑块积累会导致血管狭窄或破裂，进而引发心脑血管疾病。

accumulation /əˌkjuː.mjəˈleɪ.ʃən/ 表示“积累；积聚；积攒”，英文解释为“an amount of something that has been collected”举个🌰：Accumulations of sand can be formed by the action of waves on coastal beaches. 由于海浪的冲击作用，海滩上会堆积沙子。

artery /ˈɑː.tər.i/ 表示“动脉”，英文解释为“one of the thick tubes that carry blood from the heart to other parts of the body”举个🌰：Hardening of the coronary arteries can lead to a heart attack. 冠状动脉硬化可能导致心脏病发作。

vein /veɪn/ 表示“静脉”，英文解释为“a tube that carries blood to the heart from the other parts of the body”

2）表示“（说话、写作）风格；方式”，英文解释为“in a particular style of speaking or writing about something”举个🌰：A number of other people commented in a similar vein. 其他一些人也以类似的腔调评论。

Some blood cholesterol comes from dietary cholesterol, but far more comes from your own liver, she said. Your liver makes more LDL when you eat excess saturated fat. But eggs (unlike sausages) aren't very fatty. One egg contains just 1.6 grams of saturated fat.

她说，血液中的胆固醇有些来自膳食胆固醇，但更多是来自你自己的肝脏。当你摄入过多饱和脂肪时，肝脏会产生更多低密度脂蛋白。但是鸡蛋（与香肠不同）不含很多脂肪。一个鸡蛋中只含有1.6克饱和脂肪。

saturated fat /ˌsætʃ.ər.eɪ.tɪd ˈfæt/ 表示“饱和脂肪”，英文解释为“a type of fat found in meat, eggs, milk, cheese, etc. that is thought to be bad for your health”举个🌰：Butter and cream contain a lot of saturated fats. 黄油和奶油中含有大量饱和脂肪。

They're a complete protein source.

鸡蛋是完全蛋白质来源。

One egg contains more than six grams of protein, which nutrition experts consider high, relative to its 70 total calories.

一个鸡蛋含有六克以上的蛋白质，营养专家认为，相对于其70卡路里的总热量，这样的蛋白质含量是很高的。

calorie /ˈkæl.ər.i/ 表示“卡，卡路里（测量食物所含热量的单位）”，英文解释为“a unit of energy, often used as a measurement of the amount of energy that food provides”举个🌰：There are about 50 calories in an apple. 一个苹果大约含有50卡路里的热量。

The quality of an egg's protein is also a key benefit, said Sapna Batheja, a dietitian and assistant professor of food and nutrition at George Mason University.

乔治·梅森大学食品与营养学助理教授、营养师萨普娜·巴泰贾说，鸡蛋的蛋白质质量也是其关键优点。

dietitian /ˌdaɪ.əˈtɪʃ.ən/ 表示“饮食保健专家，营养学家，营养师”，英文解释为“a person who scientifically studies and gives advice about food and eating”

Proteins — the building blocks of your body — are all made of various combinations of 20 amino acids. Your body can make 11 of these amino acids itself, but you must get the other nine from food, Dr. Batheja said. Eggs contain all nine, making them a “complete” protein source.

蛋白质是构成人体的基石，由20种氨基酸的不同组合而成。巴泰贾说，人体可以自己制造其中的11种氨基酸，但必须从食物中获得另外九种。这九种氨基酸鸡蛋全部含有，因此是一种“完全”蛋白质来源。

amino acid /əˌmiː.nəʊ ˈæs.ɪd/ 表示“氨基酸，胺酸”，英文解释为“any of the chemical substances found in plants and animals that combine to make protein (= a substance necessary for the body to grow)”

They're rich in choline.

鸡蛋富含胆碱。

Eggs are one of the highest sources of the multitasking nutrient choline, which is important for your muscle control, metabolism, nervous system, mood and memory, among other things.

鸡蛋是多功能营养素胆碱含量最高的来源之一，胆碱对肌肉控制、新陈代谢、神经系统、情绪和记忆等都很重要。

metabolism /mɪˈtæbəˌlɪzəm/ 表示“新陈代谢”，英文解释为“the chemical processes in living things that change food, etc. into energy and materials for growth”举个🌰：The body's metabolism is slowed down by extreme cold. 严寒可以使身体新陈代谢的速度下降。

Your body can make some choline on its own, but not as much as it needs, said Razan Hallak, a dietitian at Ohio State University Wexner Medical Center.

俄亥俄州立大学韦克斯纳医学中心的营养师拉赞·哈拉克说，人体可以自己制造一些胆碱，但不能满足全部需要。

One egg contains 169 milligrams of choline, which means two eggs could put you well on your way to meeting the daily recommendation of 550 milligrams for adult males and 425 milligrams for females.

一个鸡蛋含有169毫克胆碱，这意味着两个鸡蛋就能让你达到成年男性每天550毫克和女性425毫克的推荐摄入量。

Serious choline deficiency is rare in the general public, but most people who are pregnant or nursing don't get enough. The nutrient plays a role in maintaining and creating healthy cells, Dr. Batheja said, and it's important for early brain development.

严重的胆碱缺乏症在普通人中很少见，但大多数孕妇或哺乳期女性都没有摄入足够的胆碱。巴泰贾说，这种营养物质在维持和创造健康细胞方面发挥着重要作用，对早期大脑发育很重要。
