Eggs will raise your cholesterol, and other myths.

Avoid eggs. Drink 8 glasses of water a day. Eating carbs will make you fat. Nutritional(1) advice such as this has been touted(2) for years —— but is it accurate?


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.

东华盛顿大学运动生理学家Wendy Repovich称根本没有必要。最近在达拉斯一次健康健美峰会上她极力否定几个普遍传播的营养误区。

"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.


"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."


"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.


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


"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."


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


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.


"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.
