Breast cancer (BC) treatment includes mostly chemotherapy (CT), which can cause side effects like nausea, taste changes, early satiety, slow gastric emptying and xerostomia. In this way, the individual's relationship with food may change during the treatment. The aim of this study was to evaluate the impact of chemotherapy on perceptions related to food intake of women with BC. Fifty-five women with BC were followed, and data were collected at three periods during first-line CT: beginning (T0), intermediate (T1) and end (T2). A visual analogue scale (VAS) (0 to 10 cm) for hunger, appetite for various food categories and meal enjoyment was investigated. The frequency and intensity of side effects were evaluated using a 4 cm scale. The results showed a higher prevalence of taste changes in T1 (p = 0.044) and more nausea in T1 and T2 (p = 0.018). Furthermore, the intensity of nausea was higher in T2 (p = 0.01) than in the other periods. We observed moderate hunger in T0, T1 and T2 (p = 0.113), but the overall appetite increased between T0 and T2 (p = 0.003). Meal enjoyment was reduced from T0 to T1and returned back to the initial value in T2 (p = 0.021). The appetite for salty (p = 0.004) and spicy (p = 0.03) foods was increased in T1. There was an increase of body weight (p = 0.008), body mass index (BMI) (p = 0.009) and waist circumference (WC) (p = 0.03) during CT. CT changes food hedonism, increasing the overall appetite and the appetite for salty and spicy foods. Moreover, we observed the negative impact of CT on meal enjoyment and an increase in side effects and anthropometric parameters.
