Hardly. Dietary cholesterol may contribute around 20% to our total levels
The reason is because most dietary cholesterol is in its esterified form, which must be hydrolyzed first to free cholesterol, which can then diffuse into enterocytes via NPC1l1 and scavenger receptors, packaged to chylomicrons and transported to lymph flow.
Most bodily cholesterol is of hepatic (liver) origin.
Epidemiological studies scrutinizing eggs (since you've asked) have found no issues between high egg intake and CV disease
Irrespective of that, yes, eggs and other such interventions will raise cholesterol levels, but it's both LDL and HDL, offsetting any deleterious aspect, coupled with the already only 20ish% contribution
Fat intake also plays a role in LDL/HDL, as lipids + cholesterol (both esterified & non, for both) are packaged into the same lipoproteins
However, most of it is genetic.
