One canonical stance has been that dietary cholesterol causes pathological excess serum cholesterol.
I understand this contribution has been largely discredited, in the face of other factors such as insulin resistance and omega-6 fat prevalence exerting a more direct casual impact on processes leading to lipid metabolism disregulation. Similar applies to dietary fat. Having said that, there is a correlation between higher dietary fat and higher LDL and cholesterol levels, but the later are not independently associated with cardiovascular dysfunction. Fat adapted individuals may have higher levels of these but these are associated with higher rates of metabolism as the body accepts fat as an energy currency. Conversely, there have been some reports of consumption of high cholesterol foods such as shell fish being associated with lower serum cholesterol.
On the other hand, simultaneous high insulin and high mTOR stimulation (i.e., a common consequence of the typical western diet with extended daily feeding window) is associated with inhibition of hormone sensitive lipase CPT1 and other crucial functions of lipid metabolism resulting in their pathological build up, such as DAG as intramuscular fat associated with one form of skeletal muscle insulin resistance.
My above is mostly about lipids in particular, rather than cholesterol, but I've seen the two often interlinked at large.
Some studies found that consuming high levels of red meat or white poultry resulted in higher blood cholesterol levels than consuming an equal amount of plant protein
Please specify if you are interested in broilers or layers? In layers the functioning ovary requires a lot of cholesterol being produced in the liver and then transported with the blood. In (immature) broilers this is not the case. Thus two different situations.
