Cholesterol clogs arteries. Sugar contains 0 cholesterol.

The body manufactures both “good” and “bad” lipoprotein particles. The helpful particles, high-density lipoprotein, help to remove excess cholesterol from circulation, whereas harmful particles, low-density lipoprotein, trigger atherosclerosis and hardening of the arteries. Added dietary sugar can be metabolized into triglycerides. Triglyceride levels are inexorably linked to heart disease risk. Triglycerides are packaged into very low-density lipoprotein, which is then converted into low-density lipoprotein, LDL. Increased sugar intake, therefore, leads to increased VLDL production, which in turn leads to increased production of LDL particles. LDL can become oxidized and stuck within the blood vessel walls, leading to a buildup of plaque and atherosclerosis.
