In case you're not already aware, aside from the obvious factors, increased LDL levels can result from family history, hyperthyroidism, liver problems (cirrhosis, hepatitis, ect.), kidney problems, and alcohol.
Foods can affect levels for up to two weeks prior to testing.
In refference to lowering levels, aside from following the previous advice, if you want a very effective way to cut your LDL while increasing HDL than try Beta Sitosterol and also try to find a good Sterol complex.
One other thing to note if you are considering the use of butter, everything that is not real butter, contains garbage like partially hydrogenated soy or canola oil and even though the product may have taken the cholesterol issue out of the picture, it can cause further problems elswhere in the body down the road so just limit the use of real butter.
