鸡蛋是高胆固醇食物,而高胆固醇食物会引起高胆固醇血脂。不过,饮食中胆固醇含量究竟应该控制在什么水平,必需考虑个体差异。尽管鸡蛋吃多了会升高胆固醇,一般来说,每周食用四个或者四个以下蛋黄,没有发现会增加心血管疾患。
当你考虑是否应该在饮食中包括鸡蛋时,应该考虑目前推荐的饮食中的总胆固醇量。
健康人群每日饮食胆固醇推荐量是小于300毫克;
对于有心血管疾患,糖尿病,高LDL人群,推荐量是每日小于200毫克。
一个大号鸡蛋的胆固醇含量是186毫克,全部在蛋黄里。如果你进食鸡蛋,一定注意限制当日饮食中其它来源的胆固醇,最好用蔬菜替代肉食和其它高脂肪食物。
如果你需要鸡蛋,但是想避免胆固醇,可以食用鸡蛋白,这些鸡蛋白或者由此加工的食物,不含有胆固醇。

Chicken eggs are high in cholesterol, and a diet high in cholesterol can contribute to high blood cholesterol levels. However, how much the cholesterol in your diet can increase your blood cholesterol varies from person to person. Although eating too many eggs can increase your cholesterol, eating four egg yolks or fewer on a weekly basis hasn't been found to increase your risk of heart disease.
When deciding whether to include eggs in your diet, consider the recommended daily limits on cholesterol in your food:
- If you are healthy, it's recommended that you limit your dietary cholesterol to less than 300 milligrams (mg) a day.
- If you have cardiovascular disease, diabetes or a high low-density lipoprotein (LDL, or "bad") blood cholesterol level, you should limit your dietary cholesterol to less than 200 mg a day.
One large egg has about 186 mg of cholesterol — all of which is found in the yolk. Therefore, if you eat an egg on a given day, it's important to limit other sources of cholesterol for the rest of that day. Consider substituting servings of vegetables for servings of meat, or avoid high-fat dairy products for that day.
If you like eggs but don't want the extra cholesterol, use only the egg whites. Egg whites contain no cholesterol. You may also use cholesterol-free egg substitutes, which are made with egg whites
