The tumours of man mainly develop under the influence of the long-term intake of carcinogens and cocarcinogens. There is a correlation between the level of the intake of meat and the development of tumours of the colon and the mamma. In vegetarians these forms of tumours very rarely appear. For their prevention it is necessary to decrease the consumption of sorts of meat and sausage rich in fat, so that less than 50 g of animal fat are taken in a day. It is to be recommended an increase of the consumption of food-stuffs rich in raw fibers. The caretenes, the vitamin A and the vitamin-A-acid proved as anticarcinogens. In smokers an intake of carotene and vitamin A which overwhelms the need is useful. With smoked food-stuffs in small quantities benzpyrene and nitrosamines are taken in, a restriction of the consumption of smoked meat and fish is not to be recommended. a carcinogenic effect have also aflatoxines, for which purpose no food-stuffs infested by fungi must be taken in.
人类肿瘤主要在长期摄入致癌物和辅助致癌物的影响下发展。肉类摄入量与结肠癌和乳腺癌的发生之间存在关联。在素食者中，这些肿瘤形式很少出现。为预防这些肿瘤，有必要减少富含脂肪的肉类和香肠的消费，使每日动物脂肪摄入量少于50克。建议增加富含膳食纤维的食物的消费。胡萝卜素、维生素A和维甲酸已被证明具有抗癌作用。对于吸烟者来说，摄入超过需求的胡萝卜素和维生素A是有益的。少量食用烟熏食品会摄入苯并芘和亚硝胺，不建议限制烟熏肉和鱼的消费。黄曲霉毒素也有致癌作用，因此不得食用受真菌污染的食品。
