Dietary cholesterol does not increase cholesterol, your body makes it's own cholesterol fueled by saturated and trans fats.
Serum cholesterol concentration is clearly increased by added
dietary cholesterol but the magnitude of predicted change is
modulated by baseline dietary cholesterol. The greatest response
is expected when baseline dietary cholesterol is near zero, while
little, if any, measurable change would be expected once baseline
dietary cholesterol was > 400-500 mg/d. People desiring maximal
reduction of serum cholesterol by dietary means may have
to reduce their dietary cholesterol to minimal levels (< 100-150
mg/d) to observe modest serum cholesterol reductions while
persons eating a diet relatively rich in cholesterol would be expected
to experience little change in serum cholesterol after adding
even large amounts of cholesterol to their diet. Despite modest
average effects of dietary cholesterol, there are some individuals
who are much more responsive (and others who are not responsive).
Individual degrees of response to dietary cholesterol
may be mediated by differences in cholesterol absorption efficiency,
neutral sterol excretion, conversion ofhepatic cholesterol
to bile acids, or modulation of HMG-CoA reductase or other
key enzymes involved in intracellular cholesterol economy, each
ultimately resulting in changes of plasma LDL cholesterol concentration
mediated primarily by up- or down-regulation of LDL
