Key result
By 4 years of smoking cessation, the general dietary pattern of ex-smokers became similar to never-smokers for both sexes, with intakes of polyunsaturated fat, fiber, and antioxidant vitamins increasing progressively.
Why the study?
Does the duration of smoking cessation affect nutrient intake compared to current and never-smokers in middle-aged adults?

Comparison
Ex-smokers categorized by duration of smoking… vs Current smokers and never-smokers

May partly explain lower CHD risk in ex-smokers; hypothesis-generating for nutrition-focused cessation support.

Does the duration of smoking cessation affect nutrient intake compared to current and never-smokers in middle-aged adults?
The dietary habits of ex-smokers progressively improve and resemble those of never-smokers by 4 years of cessation, which may contribute to their reduced coronary heart disease risk.
Smith et al. (1993) conducted a cross-sectional in Coronary Heart Disease Risk Factors (n=9,035). Smoking cessation duration vs. Current-smokers and never-smokers was evaluated on Dietary pattern categorization by discriminant analysis of combined nutrients. By 4 years of smoking cessation, the general dietary pattern of ex-smokers became similar to never-smokers for both sexes, with intakes of polyunsaturated fat, fiber, and antioxidant vitamins increasing progressively.
