“…A longitudinal study on breast cancer survivors (Wayne et al, 2004) did not find significant differences in fruit and vegetable intake before and after diagnosis, on the group level. Unfortunately, both measurements were performed after diagnosis, even though the patients on the first occasion were asked to recall prediagnosis diet.…”

“…One breast cancer patient cohort with repeated dietary measurements showed only modest positive changes in the diet even in subgroups of women who stated that they had changed different parts of the diet (increase in fruit, increase in vegetables, and decrease in fat). For the group in general, the only significant differences two years postdiagnosis were a lower energy intake, and an increased energy percentage from fat (Wayne et al, 2004). None of the studies included a control group of healthy women, so it is not clear whether any changes in diet among women with breast cancer differ from dietary changes made in the general female population.…”

Diet among breast cancer survivors and healthy women. The Norwegian Women and Cancer Study

Objective: To compare the diet and lifestyle in breast cancer survivors and healthy women. Design: Cross-sectional study in the population-based Norwegian Women and Cancer cohort study, using a postal questionnaire on diet, lifestyle and health. Setting: Nation-wide, population-based study. Subjects: Women aged 41-70 years. Prevalent breast cancer cases (314 short-term with 1-5 years since diagnosis, 352 longterm with 45 years since diagnosis) were identified by linkage to the Norwegian Cancer Registry. The comparison group consisted of 54 314 women. Interventions: Analyses of variance, with post hoc Bonferroni tests when significant differences were found. Results: Overall there were few differences in the diet of the three groups. Short-term survivors ate more fruits and vegetables than healthy women (Po0.0001), and consumed more of nutrients associated with fruit and vegetables (fibre, mono-and disaccharides, folate, vitamin C and potassium). Short-term breast cancer survivors also had a higher use of dietary supplements and a lower level of physical activity, but did not differ from healthy women on other lifestyle factors. The long-time survivors did not differ from any of the other groups. Conclusion: Diet and lifestyle is generally similar between breast cancer survivors and healthy women, especially more than 5 years after diagnosis. Sponsorship: This project has been financed with the aid of EXTRA funds from the Norwegian Foundation for Health and Rehabilitation.

“…Only 3 studies quantified nutrient intake variations between before and after diagnosis 20, 22, 27. They rather suggested a decrease in fatty acids and an increase in vitamin intakes, however, two of these studies were retrospective and the other focused on breast and colorectal cancers.…”

“…Dietary and alcohol intakes of cancer survivors have received increasing attention in the last decade 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29. Overall, these studies tended to suggest an improvement in dietary behavior after cancer diagnosis, as well as a strong motivation of cancer survivors to make lifestyle changes 4.…”

“…To our knowledge, only one study conducted in Norway provided prospective information on the variation of dietary and alcohol intakes between before and after cancer diagnosis,22 focusing on breast and colorectal cancers. Moreover, very few studies provided detailed data on variations of food and nutrient intakes between before and after diagnosis measured by validated quantitative dietary assessment tools 20, 22, 27…”

Modifications in dietary and alcohol intakes between before and after cancer diagnosis: Results from the prospective population-based NutriNet-Santé cohort

et al. 2017

Postdiagnosis diet and alcohol consumption may be associated with cancer prognosis, recurrence and mortality. Our aim was to investigate food, nutrient and alcohol intake variations between before and after cancer diagnosis and their determinants in a prospective cohort. Subjects (n = 696) were incident cancer cases diagnosed in the NutriNet‐Santé cohort between 2009 and 2016. Food, nutrient and alcohol intakes were prospectively collected using repeated nonconsecutive 24‐hr dietary records since subjects' inclusion (i.e. an average of 2 y before diagnosis). Mean number of dietary records per subject was 5.9 before and 8.1 after diagnosis. All dietary data before and after diagnosis were compared by mixed models. Factors associated with the main dietary changes observed were also investigated using multivariable logistic regressions. We observed a decrease in intakes of vegetables (mean decrease in intake in patients who decreased their intake=‐102.4 ± 79.8 g/d), dairy products (–93.9 ± 82.8 g/d), meat/offal (–35.5 ± 27.8/d), soy products (–85.8 ± 104.1 g/d), sweetened soft drinks (–77.9 ± 95.4 g/d), and alcoholic drinks (–92.9 ± 119.9 g/d), and an increase in broths (42.1 ± 34.9 g/d) and fats/sauces (18.0 ± 13.4 g/d). We observed a decrease in energy intake (–377.2 ± 243.5 kcal/d) and in intakes of alcohol (–7.6 ± 9.4 g/d) proteins (–17.4 ± 12.5 g/d), and several vitamins (p < 0.05) and micronutrients (p < 0.05). Conversely, lipid (19.4 ± 14.6 g/d), SFA (9.3 ± 7.0 g/d), MUFA (8.3 ± 6.3 g/d) and vitamin E (3.9 ± 3.3 mg/d) intakes increased after diagnosis. This large prospective study suggests that cancer diagnosis is a key period for nutritional changes. It highlights some healthy behaviors such as a decrease in alcohol and sweetened drink consumption, but also less favorable trends, such as a decrease in vegetable consumption and in many vitamin and mineral intakes. These results provide insights to identify and target recommendations to put forward for better nutritional care of cancer survivors.
