Abstract:

The aim of the study was to evaluate the relationship between dietary factors and the risks of stomach, colon and rectal cancers. In total, 431 cancer cases and 548 controls were included into the case-control study. Food frequency questionnaire (FFQ) was used. One-year dietary recalls on usual past diet were administered. Low tertile of daily consumption of nutrient item in the control group was defined as a reference level. The results showed that higher energy and saturated fatty acids intake increased stomach and rectal cancer risk. The elevated colon cancer risk for higher consumption of mono and polysaccharides was also observed. Otherwise, there was noticed reduced risk for stomach and rectal cancer connected with higher intake of β-carotene. The risk for evaluated cancer sites was also decreased in the group of higher consumption of fibre and vitamin E. Minerals didn’t influence significantly the estimates of the risks. The results of the study support the legitimacy of consumption of foods rich in fibre and vitamins with the restriction of energy intake for the prevention of gastrointestinal cancer. The increased risk of stomach and colon cancer, connected with higher intake of mono and polysaccharides, might be explained by the influence of these nutrients on the releasing of ghrelin. However, further accurate investigations are required to confirm this hypothesis.
