Smoking
Smoking can reduce the level of good HDL cholesterol, which is necessary for removing bad LDL cholesterol. Over time, harmful chemicals in tobacco products like nicotine would increase the risk of high cholesterol and heart disease. It is better to quit smoking to improve your health condition. Nonsmokers should also avoid direct exposure to secondhand smoke because it can also increase their risk. Consult your doctor to find a suitable option to stop smoking. [8]
