ELI5: If I eat a burger, how long does it take for the cholesterol from it to enter ones bloodstream, and what is the process behind it?

I had a blood test done recently. Beforehand I ate a horrible lunch. My cholesterol was extremely high, but a month ago it wasn't too bad. Was this caused by my lunch?

Thanks ELI5splainers!

I think it should be pointed out that the cholesterol you ingest from a burger is not the same cholesterol in your blood.

When you eat horrible food it spikes your blood pressure and causes your liver to produce its own cholesterol to reduce inflammation in your arteries.

Very little of the cholesterol you eat is absorbed.
