Cup of coffee good for cholesterol levels
Large amounts of coffee are not good for the heart and blood vessels, but drinking just a couple of cups a day reduces the risk of cardiovascular disease. Epidemiologists have known this for a few years. But how moderate coffee intake protects the heart was not known. Until now.
The researchers monitored two thousand men for five years.
The researchers observed that, after drinking coffee, the LDL in the test subjects was protected against oxidation. At least, it took longer for the LDL to be oxidized.
Immediately after drinking the coffee nothing happens - but the LDL in a sample taken half an hour after drinking coffee oxidizes more slowly. And the LDL in a sample taken an hour after intake oxidizes even more slowly.
And it's not only the phenols in coffee that are incorporated into LDL. "Incorporation into LDL was already shown for only a few other phenolic compounds", the researchers write. They are referring to "quercetin and catechin, daidzein and genistein, rutin and quercetin, and tyrosol." These substances are found in green tea, soya and olive oil.
