A case-control study on dietary factors and colorectal adenomas was conducted in the island of Majorca, Spain, from April 1987 to February 1990. Subjects were interviewed using a food frequency questionnaire. Nutrient and caloric intake was estimated using local food composition tables. The risk of colorectal adenomas was related to the consumption of sugar and pastries. Consumption of vegetables was highly protective, irrespective of the cooking procedures. Analyses by nutrients identified as protective factors fiber from fruits and vegetables, magnesium and zinc, and vitamins C, B6 and folic acid. No excess risk was found for alcohol drinking, intake of saturated fats or animal protein. Of the non-dietary factors, sedentariness in the work-place and urban residence were the only risk factors identified.
1987年4月至1990年2月，在西班牙马略卡岛进行了一项关于饮食因素与结直肠腺瘤的病例对照研究。使用食物频率问卷对受试者进行访谈。利用当地食物成分表估算营养素和热量摄入量。结直肠腺瘤的风险与糖和糕点的摄入量有关。蔬菜的摄入具有高度保护作用，无论烹饪方式如何。按营养素分析确定的保护因素为水果和蔬菜中的纤维、镁和锌，以及维生素C、B6和叶酸。未发现饮酒、饱和脂肪或动物蛋白摄入量存在额外风险。在非饮食因素中，工作场所久坐和城市居住是唯一确定的风险因素。
