Description
Two recent studies have focused on the relationship between dietary anti-oxidant intake and airways obstruction. The bronchial mucosa is vulnerable to oxidant damage either inhaled or the results of bronchial inflammatory processes and this is normally balanced by an endogenous anti-oxidant defence system which relies on an adequate supply of nutritional anti-oxidants. Over the past thirty years there has been an increase in the prevalence of wheezing illness among younger patients during a period of reduction in intake of food containing natural anti-oxidants and a relationship between these two factors has been proposed.
