Dietary profiles and anti-oxidants in a rural population of central Italy with a low frequency of cancer.

This descriptive, cross-sectional study reports the anti-oxidant activities of a population sample of 736 individuals, randomly selected from residents of two small towns of the Latina province of Italy (an area at low frequency of cancer). The circulating levels of vitamins A, C and E, ceruloplasmin, carotenoids (lutein + zeaxanthin, lycopene, alpha- and beta-carotene, cryptoxanthin), cholesterol, high-density lipoprotein cholesterol and triglycerides, as well as anthropometric measurements (skin-folds, height, weight) were evaluated. A dietary interview was also performed by means of a semi-quantitative questionnaire. All the anti-oxidants were above the cut-off points for normality, whereas body mass index, % fat and serum lipids were not clearly suggestive of a protected population. The data obtained could be useful to estimate the baseline values of protective microelements and to assess dietary profiles in populations following a Mediterranean diet.
