Omega-3 fatty acids may help to reduce the physical harm caused by smoking, according to a new study presented today at the World Congress of Cardiology. The study, carried out in Greece, assessed the effect of four-week oral treatment with 2 g/day of omega-3 fatty acids on the arterial wall properties of cigarette smokers. The results showed that short-term treatment with omega-3 fatty acids improves arterial stiffness and moderates the acute smoking-induced impairment of vascular elastic properties in smokers.
