2008-04-10 | 鹌鹑蛋与胆固醇
标签：
上次提到的关于鹌鹑蛋以及其他蛋的胆固醇资料，单独提出来重新发一遍，分类到《食材秀》，下回要找的时候比较方便。************************
老听人说鹌鹑蛋的胆固醇如何如何高，可也有人说这是谣传，说其实一个鸡蛋的胆固醇相当于5个鹌鹑蛋的胆固醇含量。
这事儿到底怎样呢？查看了一些资料，感觉上，鹌鹑蛋的胆固醇含量不像我以前听说的那样恐怖，看按照哪个标准来算了，按照某些试验数据来说，比如，有的数据说一个鹌鹑蛋的胆固醇含量是40几毫克，跟一个鸡蛋的200多胆固醇含量相比，说一个鸡蛋的胆固醇相当于5个鹌鹑蛋的胆固醇含量好像也不能说是错的。但有的数据说，一个鹌鹑蛋的胆固醇含量是70几毫克。
据说－－－鹌鹑蛋的胆固醇含量跟生蛋鹌鹑的年龄有关，年龄越大生的蛋胆固醇含量越高。而母鸡的年龄越大，产的蛋的胆固醇含量却越低。
据说－－－一个鸭蛋的胆固醇含量大约是621mg，差不多是一个鸡蛋的三倍。
据说－－－鹅蛋的胆固醇含量比较恐怖，每个1226mg，差不多是一个鸡蛋的六倍。
据说－－－关于蛋类和胆固醇确切含量的问题，是个很难给出一个精确结论的问题。不过，一些实验数据还是可以给我们的饮食提供一个大概的参考和根据的。
这里放上来两篇有关文章，感兴趣的朋友就详细看看吧。
There are several ways of looking at the eggs and cholesterol levels ofthese different species of fowl.
1... How much cholesterol is in one egg? How much saturated fatis in one egg?
One Chicken egg has cholesterol of 201mg and 1.6gms saturated fat (55 gm egg)
One Duck egg has cholesterol of 621mg and 2.6gms saturated fat (70 gm egg)
One Quail egg has cholesterol of 76mg and 0.3gms saturated fat (9 gm egg)
One Turkey egg has cholesterol of 747mg and 2.9gms saturated fat (80 gm egg)
One Goose egg has cholesterol of 1226mg and 5.3gms saturated fat (145 gm egg)
2... Eggs and cholesterol / saturated fat, per 100 grams ( a bit under 4ounces ) of egg:
Chicken eggs average out with an eggs cholesterol level of 548mg and 3.3gms saturated fat
Duck eggs average out with an eggs cholesterol level of 880mg and 3.7gmssaturated fat
Quail eggs average out with an eggs cholesterol level of 839mg and 3.6gmssaturated fat
Turkey eggs average out with an eggs cholesterol level of 995mg and 3.6gmssaturated fat
Goose eggs average out with an eggs cholesterol level of 851mg and 3.6gmssaturated fat
3... Eggs cholesterol per gram of yolk.From better to worse:
guinea fowlhas 12.77mg cholestrol, there followed by chicken, pheasant, quail, turkey,duck, and goose, with the dove egg yolk the worst with 21.99mg of cholestrol /gram. Bair and Marion 1978.
Understanding the EGGS and CHOLESTEROL Facts and Figures:The concentrations of eggcholesterol and egg saturated fat may differ from one flock of birds to the next. For example, quail egg cholesterol can range from about 76 mg up to amassive 400mg of cholestrol per 9 gram egg!
Further, Bair and Marion made an interesting observation - egg yolk cholesterol appears to decrease with the age of the hen, at least in chickens anyway.
The concentrations of cholesteroland saturated fat reported in any common food table should be treated strictlyas a guideline, NOT a fact. Likewise, egg cartons may only give the average cholesterol level for the species, rather than from the farm thatproduced them.
All this means that eggs andcholesterol is a very difficult topic to discuss with any precision, but theguidelines provided here on eggs and cholesterol should provide a solidreference point to work from at least.

另外一篇提到，鹌鹑蛋的胆固醇含量跟生蛋鹌鹑的年龄有关，年龄越大生的蛋胆固醇含量越高。三个月大的鹌鹑生的蛋，胆固醇含量的浮动范围是每个蛋（32.86-48.13)， 而11个月大的鹌鹑生的蛋，每个的胆固醇含量的浮动范围则是（30.92-108.51），因此，作者说
“The research conclude that the cholesterol content of average10gram is much lower than previously reported by other researchers and foundthat the cholesterol is higher in larger egg. With the practice of cullingquails older than 10 months, the produce quail eggs will be within the weightrange of 10 ± 1 gram and having average cholesterol 46.3mg / whole egg.”
