I have seen over 6 studies showing that eating 6 eggs a day for 6 weeks has no effect on people's total cholesterol levels. I first saw a study on this in 1982 (after telling the brilliant nutritionist who told me about it, Dana Godbout-Laake, that she was nuts to say this—she promptly sent me a stack of studies confirming that eggs don't raise cholesterol, and I had to pull my foot out of my mouth!). Now a study shows that adding an extra egg each day increased good cholesterol, called HDL, while lowering total cholesterol.
The authors of this study conclude, "In the majority of healthy adults, an addition of one egg per day to a normal fat diet could raise HDL-c levels and decreased the ratio of TC to HDL-c. Therefore, egg consumption might benefit blood cholesterol."
