“…Mandez et al (2002) exclusively studied ascorbic acid status in smokers and non-smokers and came to conclusion that smokers are at greater risk of chronic diseases due to low intake of ascorbic acid [10]. The observations of Preston et al (2003) are still more important in this regard who reported that ascorbic acid status is compromised in smokers and that environmental tobacco smoke reduces ascorbic acid status even when exposure to it is minimal [11].…”

Aim: To assess serum ascorbic acid and alpha-tocopherol levels in bidi smokers, tobacco chewers and tobacco nonusers. Materials and Methods: Forty smokers [25 subjects smoking ≤24 bidi /day (moderate) and 15 subjects smoking > 24 bidi/day (heavy) with a smoking habit of > 10 years, 20 subjects tobacco chewers ≥10 g tobacco/day) chewing for > 10 years] were included in the study.All selected subjects were normal with no symptoms of any disease. They were classified on the basis of age, BMI and with and without alcohol consuming habit. Serum ascorbic acid was measured by dinitrophenyl hydrazine reagent and alpha-tocopherol by ferric chloride oxidation. Result: Serum ascorbic acid levels in moderate smokers, heavy smokers, tobacco chewers and control,were 0.31 -+0.13, 0.26+0-.16, 0.40+0.2-6 and 0.50+-0.09.In the respective group's alpha-tocopherol levels were 0.674±0.46, 0.94±0.43, 0.95±0.61 and 1.39±0.73.Conclusion: Both bidi smoking and tobacco chewing decreased ascorbic acid and alpha-tocopherol levels. No discernible trends were found with BMI and alcohol.

“…201 Another risk group is children exposed to environmental tobacco smoke via passive smoking. Even at a low amount of smoke exposure, children showed reduced plasma ascorbate concentrations, by an average of 3.2 µmol/l compared with unexposed children who received equivalent quantities of vitamin C. 176 Plasma ascorbic acid concentrations in passive smokers were intermediate between levels found in smokers and those found in non-exposed non-smokers. 242 Hypovitaminosis C (i.e.…”

With the progressive elimination of dietary protein-energy deficits, deficiencies of micronutrients are emerging as the limiting factors in ensuring children's optimal health. Data from several countries in Asia and Latin America indicate that deficiencies of vitamin C and zinc continue to be at alarming levels. This article reviews the roles of vitamin C and zinc in supporting children's growth and development, with a particular focus on the complementary roles they play in supporting immune functions and combating infections. The contemporary relevance of vitamin C and zinc deficiency in the Asian and Latin American regions, both undergoing a rapid nutritional transition, are also discussed. Overall, there is increasing evidence that deficiency of vitamin C and zinc adversely affects the physical and mental growth of children and can impair their immune defences. Nutrition should be the main vehicle for providing these essential nutrients; however, supplementation can represent a valid support method, especially in developing regions.

“…123 After controlling for age, gender, vitamin C intake, and multivitamin use, children exposed to high levels of SHS had about the same reduction in serum ascorbic acid levels observed in children who were active smokers ( Table 2). Preston et al 124 found plasma vitamin C levels to be on average 3.2 mol/L lower in children exposed to SHS compared with unexposed children (both groups had similar dietary intake of vitamin C).…”

Cardiovascular Effects of Secondhand Smoke

Background-Secondhand smoke increases the risk of coronary heart disease by Ϸ30%. This effect is larger than one would expect on the basis of the risks associated with active smoking and the relative doses of tobacco smoke delivered to smokers and nonsmokers. Methods and Results-We conducted a literature review of the research describing the mechanistic effects of secondhand smoke on the cardiovascular system, emphasizing research published since 1995, and compared the effects of secondhand smoke with the effects of active smoking. Evidence is rapidly accumulating that the cardiovascular system-platelet and endothelial function, arterial stiffness, atherosclerosis, oxidative stress, inflammation, heart rate variability, energy metabolism, and increased infarct size-is exquisitely sensitive to the toxins in secondhand smoke.
