Smoking in French men is associated with reduced vitamin E, C, and carotene intake, as well as altered oxidative stress indexes. This study highlights the importance of public health intervention for smokers in France.
Researchers at University at Buffalo found a miniscule increase in free radicals in the blood reflects lung damage equivalent to 3-5 years of aging. Oxidative stress was also associated with narrowing of pulmonary airways, while bilirubin showed a positive relationship to lung function.
A population-based study found that higher vitamin C levels were associated with lower oxidative stress and a reduced risk of cell damage. The study involved 393 participants and measured the actual level of vitamin C in their blood serum.
