The recommendation that not more than 300 mg cholesterol be consumed d
aily to prevent high serum cholesterol levels and coronary heart disea
se is often used to justify a restriction of egg intake to three or fo
ur per week. One egg contains about 200 mg of cholesterol, but eggs ar
e also excellent and relatively inexpensive sources of essential amino
acids and certain vitamins. In this paper, the place of eggs in a pru
dent, cholesterol-lowering diet as a substitute far other animal produ
cts, is scrutinised. The extra cholesterol, where considered as the on
ly variable, will increase serum cholesterol levels, but the effect is
relatively small. The exclusion of eggs from the diet should be weigh
ed against deprivation of essential nutrients especially in vulnerable
groups. While restriction of egg intake in westernised populations se
ems justifiable, the upper limit of three or four per week may not alw
ays be applicable, depending on the overall diet and lipid profile of
the individual.
