Dietary total antioxidant capacity in cancer patients undergoing ambulatory treatment.

Abstract

OBJECTIVE: To evaluate the dietary total antioxidante capacity and associated factors in cancer patients undergoing ambulatory treatment. METHODS: A cross-sectional study carried out with cancer patients in 2020, evaluating sociodemographic data, disease treatment, food frequency and a 24-hour recall. Anthropometric measurements were taken for weight classification. To determine the total antioxidant capacity of the diet (CATd) a database with the total content of food antioxidants was used. Statistical significance of p<0.05 was adopted. RESULTS: The median antioxidant consumption was 3.29±1.82mmol/g. Patients with CATd above the median had higher consumption of carbohydrates, proteins, lipids, vitamin C and E (p<0.05). There was no relationship between CATd and anthropometric measurements. CONCLUSION: The antioxidant capacity of the diet was associated with the consumption of macronutrients and vitamin C and E, but was not related to anthropometric measurements.
