Background: Cigarette smoking, a cardiovascular risk factor leading to
oxygen free radical formation, is involved in the development of
serious pathological conditions. On the other hand, a healthy diet and
adequate supplementation can help prevent many diseases. The aim of our
study was to evaluate in healthy light smokers the effects of
supplementation with mixed fruit and vegetable juice powder concentrate
on homocysteine metabolism and oxidative status. Methods: In this pilot
study, 32 healthy volunteers, 16 light smokers and 16 non-smokers, on
twice daily supplementation were monitored at time zero and after 30
days. Plasma homocysteine, and serum vitamin B(12) and folate
concentrations were measured by immunoenzymatic assays; reactive oxygen
species, total antioxidant capacity and thiol groups by
spectrophotometric methods; and total and free malondialdehyde
concentrations by gas chromatography-mass spectrometry with isotopic
dilution. Results: Baseline free malondialdehyde concentrations were
significantly higher in smokers than in non-smokers and normalised
after 30-day supplementation. Baseline results for all the other
parameters remained unchanged after supplementation, with no
significant differences between smokers and non-smokers. Conclusion:
This is the first study showing a significant decrease in free
malondialdehyde levels in light smokers after 1-month phytonutrient
supplementation.
