Cholesterol - Cholesterol levels in the body actually have VERY little to do with dietary cholesterol intake. Poor cholesterol levels in the body are the result of inflammation. Mainly from a diet high in refined sugar, processed carbs, saturated and trans fats.
Raw eggs - The answer really depends on the eggs you are eating.
It is safe to eat raw eggs - ONLY if they come from free range, organic, pasture raised, humane eggs.
Your regular $1/dozen eggs at the grocery market - cook them. They come from sick chickens that are raised in over populated chicken coops their entire life.
Raw eggs from a healthy chicken that is fed a high quality diet - perfectly fine.
I am not sure where you are located but if you are able to get eggs from a local farmer at the farmer's market, those are the best eggs you can buy.
Egg limit - I eat 3-4 whole eggs every day and routinely include whole eggs in all my clients diets. I wouldn't set a limit.
