Well if you happen to be allergic to them, then yes they can be bad for you. If you have no allergens to eggs whatsoever then I don't think there is enough cholesterol in eggs to justify not each a few a day. Like others on this thread said, they have the highest quality of protein next to fish, and has lots of good fats in them too. That is unless you are allergic to them.
Also, if you are like me and happen to be allergic to dairy products, then don't make the mistake I made and assume eggs are another form of dairy. Take allergy tests.
