Many people believe that egg increase cholesterol. It is actually a true fact that egg yolks have a lot of cholesterol�and so may weakly affect blood cholesterol levels�eggs also contain nutrients that may help lower the risk for heart disease, including protein, vitamins B12 and D, riboflavin, and folate. The studies shows that eating eggs daily does not have a significant impact on blood cholesterol levels than the effect of saturated fat in the diet. The amount of saturated fat in the diet exerts an effect on blood cholesterol that is several times greater than the relatively small amounts of dietary cholesterol. According to a study of 9,500 people reported in Medical Science Monitor showed that eating one or two eggs a day did not increase the risk of heart disease or stroke among healthy adults. Most recently, a 2007 study of 9500 people that was reported in Medical Science Monitor found that eating one or two eggs per day did not increase the risk of heart disease or stroke among healthy adults. The study noted that eating eggs may actually be associated with a decrease in blood pressure. A review of more than 25 studies that published in the Journal of the American College of Nutrition in 2000 showed that eating an egg a day isn’t associated with increased risk of heart disease in healthy men and women, even after taking into account other aspects of their diet that may increase the risk for heart disease. The researchers at the Yale Prevention Research Center in 2005 showed that adding two eggs a day to a healthful diet did not significantly increase blood cholesterol levels in young or middle-aged men and women with normal or even moderately elevated blood cholesterol levels. A 1999 Harvard University study that collected data from more than 100,000 men and women found no significant difference in heart disease risk between healthy adults who ate less than one egg a week and those who ate more than one egg a day and that eating up to one egg a day is unlikely to have a significant overall impact on the risk of heart disease or stroke. Cholesterol in eggs has very little effect on blood cholesterol levels in healthy adults. Eggs are an excellent source of nutrients. If you need to reduce your cholesterol level it is more important that you cut down on the amount of saturated fat in your diet from foods like fatty meat, full fat dairy products and cakes, biscuits and pastries.
