To further elucidate the role of dietary habits, 1,225 subjects with cancer of the colon, 728 with cancer of the rectum and 4,154 controls, hospitalized with acute non-neoplastic diseases, were interviewed between 1992 and 1996 in 6 different Italian areas. The validated food-frequency questionnaire included 79 questions on food items and recipes, categorised into 16 food groups. After allowance for non-dietary confounding factors and total energy intake, significant trends of increasing risk of colorectal cancer with increasing intake emerged for bread and cereal dishes (odds ratio [OR] in highest vs. lowest quintile 5 1.7), potatoes (OR 5 1.2), cakes and desserts (OR 5 1.1), and refined sugar (OR 5 1.4). Intakes of fish (OR 5 0.7), raw and cooked vegetables (OR 5 0.6 for both) and fruit other than citrus fruit (OR 5 0.7) showed a negative association with risk. Consumption of eggs and meat (white, red or processed meats) seemed uninfluential. Most findings were similar for colon and rectum, but some negative associations (i.e., coffee and tea, and fish) appeared stronger for colon cancer. Our findings lead us to reconsider the role of starchy foods and refined sugar in light of recent knowledge on the digestive physiology of carbohydrates and the insulin/ colon cancer hypothesis. The beneficial role of most vegetables is confirmed, with more than 20% reduction in risk of colorectal cancer from the addition of one daily serving. Int.

The results of two FFQ administrations at an interval of 3 to 10 months (median = 5.4 months) to 452 volunteers (144 males and 308 females; median age = 50 years) from three Italian provinces (Pordenone, Genoa, and Forli) were compared. Pearxm correlation coefficients (r) between crude num'ent intake (unadjusted for energy) ranged from 0.50 for vegetable fat to 0.80 for alcohol, with most values falling between 0.6Oand 0.70 (median r = 0.67). Adjustment of nutrient intakes for total energy slightly deer-d most coe~cients (median r = 0.60). The agreement between the two measurements did not differ substantially by sex, age, education, and interval between interviews. The contribution of specijic FFQ components (i.e., frequency-only questions, open questions, portion sire, and fat intake pattern) was also assessed separately with respect to the perfomuznce and reproducibility of nutrient measures, yielding, in general, very similar results. The seven questions concerning individual fat intake pattern, which were used to modulate the composition of various recipes, led, however, to a significant increase in mean daily intake of vegetable fat, oleic acid, and vitamin E, but a reduction of estimated daily intake of linoieic acid and p~ly~~~~rated fatty acids.
