With surgery being the most common treatment for those with colorectal cancer (CRC), decreasing risk of post-surgical complications is key [Brouwer et al., 2018 as cited in reference i]. Research suggests that post-surgical complications may in part be related to impaired gut health [Stavrou et al., 2017 and Schietroma et al., 2017 as cited in reference i]. Due to its relation to gut health, fiber intake presents a promising focus of study. In the below study, the authors explore the relationship between dietary fiber intake and postoperative complications in individuals with CRC [i].
Study
Association of habitual preoperative dietary fiber intake with complications after colorectal cancer surgery
JAMA Surgery
This prospective cohort study included 1399 individuals from the Colorectal Longitudinal, Observational Study on Nutritional and Lifestyle Factors (COLON) study. Participants were from 11 hospitals in the Netherlands with CRC planning elective abdominal surgery. Participants completed FFQs after diagnosis on their dietary intake during the 1 month prior to diagnosis. Dietary fiber was looked at per 10 grams per day as well as in tertiles, and the source of fiber (fruits, vegetables, cereals, whole grains, refined grains) was also studied. Outcomes were any complications, surgical complications, and anastomotic leakage 30 days after CRC surgery [i].
Findings
The authors found:
1. Higher dietary fiber intake was associated with lower risk of any complications and surgical complications
2. There was no association between higher dietary fiber intake and anastomotic leakage
3. Higher dietary fiber intake was associated with lower risk of any complications in women, but no association was found in men
4. When looking at the different sources of fiber, the associations were the strongest with fiber coming from vegetables [i]
For the Patient and Caregiver
The recommendation for daily fiber intake in the United States is 21 grams for women over 50, 25 grams for women 50 and under, 30 grams for men over 50, and 38 grams for men 50 and under. Increasing fiber intake allows individuals to feel more satisfied after eating, as well as improve cholesterol levels, regulate blood sugar, and promote gut health. Add fiber to your eating pattern using our recipes. When looking at nutrition facts labels, 2 grams of fiber per serving is a good source, and 3 or more grams of fiber per serving is a great source. The below sample day provides 29 grams of fiber.
High Fiber Sample Day
Breakfast: Oatmeal made with ½ cup dry old fashioned oats (4 g fiber), ¾ cups water, 1 Tbsp almond butter (1.5 g fiber), ⅓ cup plain Greek yogurt, 1 cup frozen blueberries (6 g fiber), 1 tsp cinnamon
Lunch: Bento box with 2 hard boiled eggs, ⅓ avocado (3 g fiber), 1 oz mixed nuts (1 g fiber), 1 plum (1.5 g fiber)
Snack: 2 wasa crackers (6 g fiber), 1 oz cheese, 4 slices cucumber
Dinner: 3 oz grilled chicken, 1 cup baby spinach (1 g fiber), 2 Tbsp pumpkin seeds (1 g fiber), ½ sweet potato with the skin (2 g fiber), 2 Tbsp hummus (2 g fiber)
For the Healthcare Team
This research offers an opportunity to consider a preoperative protocol related to fiber intake for individuals with CRC. Further research is needed to elucidate how timing fiber intake may be the most beneficial for postoperative outcomes. For example, in this study, fiber intake in the 1 month prior to diagnosis was evaluated. However, it would be important to consider if outcomes could benefit if fiber intake was increased in the weeks leading up to surgery, even if fiber intake was lower previously.

Susan started Savor Health after losing a close friend to a brain tumor and, through that experience, becoming aware of the significant unmet nutritional needs of people with cancer. Struck by the fact that her friend was told “nutrition doesn’t matter” and “eat whatever you want,” Susan read the evidence-based literature on the subject, interviewed oncologists, oncology nurses and oncology dietitians, as well as patients and caregivers, and found that, in fact, nutrition does matter in oncology. Armed with solid scientific evidence supporting the clinical and quality of life benefits of proper nutrition, Susan left Wall Street and created Savor Health, an AI-based provider of personalized and clinically appropriate nutrition solutions for cancer patients, their caregivers and health enterprises. Susan brings to Savor Health over 25 years of industry experience in healthcare and business as well as expertise in strategy, finance and management.
