Digestive cancer is a major public health problem with discreet and insidious evolution until the appearance of serious consequences in terms of morbidity and mortality. This work aims to demonstrate the impact of a diet rich in ascorbic acid on the evolution of digestive cancer. A descriptive observational study was carried out over a period of 3 months, for 30 patients with digestive cancer selected at the hospitals of Tlemcen, Nedroma and Ghazaouet, where a questionnaire was conducted. A diet was proposed, and a vitamin C dosage was carried out on the plasma of the patients before and after the introduction of this diet. Tumor locations were associated with fruits and vegetables consumption (p= 0.016). In addition, the vitamin C mean after the diet was significantly higher than before the diet (p< 0.0001), and there was a significant association between the improvement of patients' health and the vitamin C-rich diet (p< 0.0001), with a decrease in the effects of chemotherapy (39.13 %) or even a stabilization (34.78 %). Also, an improvement in the health status of the cancer patients (26.09 %) has been shown. In order to target preventive actions against digestive cancer, a better knowledge of the lifestyle of cancer patients, combined with a balanced diet supplemented with vitamin C, and a restriction of foods that acidify the blood pH is highly recommended.
