As with beans, apples are an excellent source of LDL-lowering soluble fiber, primarily pectin. Research also shows that eating an apple a day (or better yet, two) can slow the oxidation of LDL cholesterol thanks to antioxidant polyphenols found primarily in the skin (so don't peel them). Antioxidants are important because when LDL cholesterol interacts with free radicals to become oxidized, it is more likely to promote inflammation and plaque build-up in the arteries. Cholesterol is an organic molecule. It is a sterol (or modified steroid), a type of lipid. Cholesterol is biosynthesized by all animal cells and is an essential structural component of animal cell membranes. It is a yellowish crystalline solid.

(See more)Cholesterol is essential for all animal life, with each cell capable of synthesizing it by way of a complex 37-step process. This begins with the mevalonate or HMG-CoA reductase pathway, the target of statin drugs, which encompasses the first 18 steps. This is followed by 19 additional steps to convert the resulting lanosterol into cholesterol. A human male weighing 68 kg (150 lb) normally synthesizes about 1 gram (1,000 mg) of cholesterol per day, and his body contains about 35 g, mostly contained within the cell membranes. Typical daily cholesterol dietary intake for a man in the United States is 307 mg.
Most ingested cholesterol is esterified, which causes it to be poorly absorbed by the gut. Wikipedia
