Beschreibungen/Notizen
Cigarette smoking is the most popular form of smoking, and is one of the most prevalent social habits worldwide. It has been estimated that almost 1.1 billion people are classified as smokers of whom over 2 million are expected to die every year. This makes smoking the leading preventable cause of death and disability in the world. In addition to mortality, smoking was shown to deplete the body of its endogenous antioxidants such as vitamins C and E, β-carotene, ubiquinol, glutathione and α-lipoic acid. Antioxidant depletion was shown to increase individual vulnerability to free radicals and other oxidant species produced by cigarette smoking and therefore leads to elevated morbidity, aging, and death. Dietary supplementation with antioxidants can reduce the overall oxidative burden that is increased by cigarette smoking. However, supplementation can not substitute for the greater benefits of smoking cessation.
