Coffee drinking induces incorporation of phenolic acids into LDL and increases the resistance of LDL to ex vivo oxidation in humans
While there is no shortage of controversy about whether lowering cholesterol has any real effect on cardiovascular risk, there is much evidence to support the concept that LDL cholesterol does not do damage to us until it gets damaged itself. This damaged particle is then referred to as an oxidized LDL (oxLDL).
So in this study, the authors found that coffee drinking was shown to protect these LDL molecules from becoming damaged. The problem with coffee today is that we load it up with sugar, artificial sweeteners, whip cream and creamers, all of which drastically effects the health balance of the drink.
