    The following appeared in the summary of a study on headaches suffered by the residents of Mentia.
    "Salicylates are members of the same chemical family as aspirin， a medicine used to treat headaches. Although many foods are naturally rich in salicylates， for the past several decades， food-processing companies have also been adding salicylates to foods as preservatives. This rise in the commercial use of salicylates has been found to correlate with a steady decline in the average number of headaches reported by participants in our twenty-year study. Recently， food-processing companies have found that salicylates can also be used as flavor additives for foods.
