Americans can eat eggs without feeling guilty, according to new nutritional guidelines issued by the U.S. government.

A person can eat as many eggs as they like each day, the updated guidelines say. One large chicken egg has about 186 milligrams of cholesterol, according to the U.S. Department of Agriculture. Most of that is in the yellow center, or the yolk.
 
Older guidelines restricted cholesterol intake to 300 milligrams a day. Two eggs would be more than the daily limit.
 
The guidelines were issued by the U.S. Department of Agriculture and the Department of Health and Human Services.
 
The government guidelines are issued every five years. It is designed to help set nutritional standards for school lunch programs and federal food aid.
 
The new guidelines cautioned that “individuals should eat as little dietary cholesterol as possible.”
 
In the past, guidelines have led to reduced sales and hurt agricultural markets. In 1977, the guidelines recommended avoiding cholesterol. That recommendation led to a decline in egg sales.
 
Other tips to stay healthy included advice to limit intake of sugars to 10 percent. Saturated fat calories found in red meat, butter, cheese, whole milk and ice cream should be limited each day to 10 percent.
 
The guidelines also suggested Americans move away from a diet full of animal protein and sodium. The guidelines promoted eating more fruits, vegetables and nuts.
 
The government has long recommended eating breakfast each day as a way to stay fit. The latest guidelines do not recommend that breakfast is necessary.
 
Some are critical of the new guidelines. Mayo Clinic's Dr. Donald Hensrud told Time magazine that the new recommendations do not address weight management. Hensrud also mentioned that the recommendations failed to note the positive reports of how coffee decreases the risks of diabetes and Parkinson’s disease.
 
Harvard professor and physician Walter Willett was candid in his observations.
 
“This is a loss for the American public, and a win for big beef and big soda,” Willett said.
 
“The problem isn’t just that the public gets misleading, censored information, but that these guidelines get translated into national food programs. ... This then gets directly translated into unnecessary premature deaths, diabetes, and suffering … of course this goes on to mean greater health care costs for all. It is all connected.”

根据美国政府发布的最新营养指南,美国民众可以尽情吃鸡蛋而不必心怀内疚。

 
最新的指南称,每人每天想吃多少鸡蛋都可以。据美国农业部统计,一个大鸡蛋大约含186毫克胆固醇,多数集中在蛋黄。
 
旧指南限制每天胆固醇的摄入量为300毫克,两个鸡蛋就超出了每天的最高摄入量。
 
该指南由美国农业部和卫生与公共服务部发布。该政府指南每五年发布一次,旨在帮助学校午餐项目和联邦食物援助设立准则。
 
新指南警告称:“个人应尽量少摄入饮食中的胆固醇”。
 
在过去,营养指南导致销售下降并损害了农业市场。1977年,营养指南建议避免摄入胆固醇,该建议导致鸡蛋销售下跌。
 
其它关于保持健康的建议包括:限制糖的摄入量至10%,红肉、黄油、奶酪、全脂奶和冰激凌所含的饱和脂肪卡路里,每天的摄入量应控制在10%。
 
指南还建议美国民众摒弃以动物蛋白和钠为主的饮食习惯,鼓励多吃水果、蔬菜和坚果。
 
政府长期倡导每天吃早饭以保持健康。最新的指南却并为建议必须吃早饭。
 
有些人指责新指南。梅约诊所的Donald Hensrud医生告诉《时代周刊》:新的健康指南并未强调体重管理。Hensrud还提到指南也未提到咖啡有益于降低患糖尿病和老年痴呆的风险的正面报道。
 
哈佛教授及医生Walter Willett直言不讳:“这将是美国公众的损失,也是大块牛肉和大杯苏打水的胜利。”
 
“问题不仅仅是公众被误导,让公众得到审查后的信息。而且这些指南体现到了国家食品计划,这将直接导致不必要的过早死亡、糖尿病和折磨……当然长此以往,还意味着大家要承担更庞大的医疗成本,这些都是关联的。”
