Low Glycemic Load Diet in Patients With Stage I-III Colon Cancer

Summary

This pilot clinical trial studies the feasibility of a low glycemic load diet in patients with stage I-III colon cancer. A low glycemic load diet includes foods that have low scores on the glycemic index. The glycemic index is a scale that measures how much a certain carbohydrate causes a person's blood sugar to rise. A low glycemic load diet may help decrease the chance of cancer coming back and improve the survival in patients with colon cancer.

Conditions

• Stage I Colon Cancer
• Stage II Colon Cancer
• Stage III Colon Cancer
• Stage I Rectal Cancer
• Stage II Rectal Cancer
• Stage III Rectal Cancer

Interventions

OTHER

questionnaire administration

Ancillary studies including three day food record, twenty-four hour dietary recall, and a food acceptability questionnaire.

OTHER

laboratory biomarker analysis

Correlative studies

BEHAVIORAL

Standard Dietary Intervention

Participants will be contacted by a nutritionist, in person every 2 weeks with phone contact on the alternating weeks. At the initial visit, each participant will be given verbal and written patient education materials, including low glycemic load diet recipes, meal plans, food preparation, and grocery shopping information. Individual instruction will be tailored to their baseline dietary preferences (e.g. vegan, allergies, etc).

BEHAVIORAL

Intensified Dietary Intervention

Patients will be contacted weekly, in person, by a nutritionist . Participants will take part in a cooking demonstration at the time of their initial visit. The demonstration will be hands-on and participants will be able to sample foods and recipes. In addition to grocery shopping information, participants will be accompanied by a nutritionist to their local grocery store to practice new shopping habits for their target dietary glycemic load. Each participant will also receive weekly random phone calls to assess his or her progress.
