雅思閱讀_有關(guān)營養(yǎng)誤區(qū)的句式及詞匯

雅思托?？荚囀且粋€非常有難度的考試，相信很多在備考階段的小伙伴們，每天都在關(guān)注一些雅思相關(guān)的消息。有同學(xué)問：雅思閱讀：有關(guān)營養(yǎng)誤區(qū)的句式及詞匯？今天，一起來看看吧。

Eggs will raise your cholesterol, and other myths.

別吃雞蛋;一天喝八杯水;碳化物會讓你變胖;多年來這些營養(yǎng)建議受到大肆宣傳，但是它們可靠么?

Not necessarily, according to Wendy Repovich, an exercise physiologist(3) at Eastern Washington University, who did her best to dispel several common nutrition misconceptions(4) during a health and fitness summit held recently in Dallas.

東華盛頓大學(xué)運動生理學(xué)家Wendy Repovich稱根本沒有必要。最近在達(dá)拉斯一次健康健美峰會上她極力否定幾個普遍傳播的營養(yǎng)誤區(qū)。

Eating eggs will raise your cholesterol(5). This myth started because egg yolks(6) have the most concentrated amount of cholesterol in any food, Repovich said. However, when eaten in moderation, eggs do not contain enough cholesterol to pose health risks, she said.

Repovich說：吃雞蛋會增加膽固醇的說法源自雞蛋比其他食物含有更高濃度的膽固醇，但是適量食用不會對健康造成威脅。

Most people avoid eggs and probably if they have any kind of cardiovascular(7) risk their physicians tell them to avoid eggs, Repovich said. But really, there aren't a whole lot of studies that show that one or two eggs a day really make a difference to cholesterol levels.

很多人不吃雞蛋，或許如果他們有心血管疾病隱患，他們的醫(yī)生建議他們遠(yuǎn)離雞蛋。但事實上，目前沒有足夠的研究證明每天1-2個雞蛋會影響體內(nèi)膽固醇水平。

Eating carbohydrates(8) makes you fat is another myth. Cutting carbs from the diet may help a person shed pounds due to water loss from a decrease in carbohydrate stores, Repovich said, but eating carbs in moderation does not directly lead to weight gain.

吃碳水化合物會引發(fā)肥胖也是一個誤區(qū)。不吃碳水化合物可以減少體內(nèi)水分含量，以此造成體重減輕。但是適量攝入碳水化合物并不能直接導(dǎo)致體重增加。

Here's another myth. Drink 8 glasses of water a day. Repovich said people need to replace water lost through breathing, urinating, sweating each daybut that doesn't necessarily total 64 ounces of water.

還有一個誤區(qū)：每天喝8杯水。Repovich說人體的確需要喝水來補充由于呼吸、小便、流汗流失的水分，但真沒必要一天喝64盎司。

I see an awful lot of people carrying bottled water around, Repovich said. I think people are still under the impression that they have to drink 8 glasses of water a day, but most people don't realize they get water from other sources in the diet.

我看見好多人背著水瓶走來走去。我覺得人們還在受這條謬誤的影響，但是大多數(shù)人都沒意識到食物中也含有水分。

And too much water can be harmful, Repovich warned, leading possibly to an imbalance in the body of sodium(9), a condition called hyponatremia.

Repovich還警告說喝太多水是有害的，可能引起體內(nèi)鈉含量失衡，患上低鈉血癥。

It's also a myth, Repovich said, that everyone needs vitamin supplements, although she admits to popping a multivitamin(10) each morning. People who eat a variety of fruits, vegetables, whole grains, along with moderate amounts of a variety of low-fat dairy and protein and the right quantity of calories, probably don't need a vitamin supplement, she said.

盡管Repovich每天早晨都泡一片多種維生素片，但她說并非所有人都需要補充維生素。如果一個人每天食用多種水果、蔬菜、全麥，適量攝入低脂奶制品、蛋白質(zhì)和卡路里，就不用再吃維生素片了。

But for the most part, we don't eat the way we should so probably a simple multivitamin is good for most people, Repovich said.

但是基本上都無法做到，因此維生素片對大多數(shù)人來說是好的。
