Food help for colorectal cancer

153,000 new diagnoses of colorectal cancer per year (106K colon + 46K rectal); 53,000 deaths. 3rd leading cancer killer in US. Rates in under-50 increasing 2% annually since 1995. USPSTF 2021 lowered screening age to 45 years. Black men have 24% higher mortality. Diet is significant modifiable factor: high-fiber, low processed-meat diet reduces risk 40-50%.

Screening and prevention — covered by ACA

• Under ACA Section 2713 (PL 111-148), all plans must cover colorectal screening without copay for ages 45-75:
• Annual FIT (Fecal Immunochemical Test) — at home, free, no colonoscopy needed if negative. Cologuard every 3 years.
• Colonoscopy every 10 years — if normal. Every 5 years if family history or findings.
• Flexible sigmoidoscopy every 5 years.
• CT colonography every 5 years.
• Medicare covers from 50; now also from 45 under IRA Section 11405.
• Medicaid expansion covers fully.

Diet to reduce progression and recurrence

• Fiber 25-30 g/day — studies show 8-10% lower risk per 10g/day. Oats, beans, lentils, fruits, vegetables, whole grains.
• Whole grains — 3+ servings/day associated with lower mortality.
• Dairy — 1-2 servings/day (calcium reduces risk).
• Fatty fish 2x/week — omega-3.
• Beans, lentils — 4+ servings/week.
• Coffee — 4+ cups/day associated with 24% lower recurrence (NEJM 2017).
• Low-dose aspirin (81 mg/day) — studies show reduction in incidence and recurrence. Do NOT start without doctor (bleeding risk).
• Vitamin D 1,000-2,000 IU/day — common deficiency; levels >30 ng/mL associated with lower mortality.
• Calcium 1,000-1,200 mg/day.

What to avoid

• Processed red meat — WHO Class 1A carcinogen. 50g/day of bacon/sausage/ham increases CRC risk 18%.
• Unprocessed red meat — Class 2A; >3 servings/week increases risk.
• Burned/charred meat — HCAs/PAHs.
• Alcohol — >2 drinks/day increases CRC risk 25%.
• Added sugar and sugar-sweetened beverages — increases risk in young adults.
• Ultra-processed foods.

Post-surgery and ostomy adaptations

If you have an ostomy (ileostomy or colostomy):

• Small frequent meals — 5-6 meals/day, CHEW well.
• Essential hydration — ileostomy loses more water, electrolytes. 8-10 glasses/day. Oral rehydration solutions (Pedialyte, Liquid IV).
• Initially avoid: raw vegetables, seeds, nuts, fruit skins, popcorn (obstruction risk).
• Foods that may cause gas: broccoli, cabbage, beans, onion, sodas.
• Foods that may thicken: white rice, bananas, white bread, cheese (useful if diarrhea).
• Foods that loosen: citrus juices, fatty foods.
• Ostomy supplies covered by Medicare under DME (HCPCS A4361-A4434): bags, barriers, accessories. Brands: ConvaTec, Hollister, Coloplast.
• $50/month reimbursement with insurance typical; if not, Friends of Ostomates Worldwide-USA and UOAA have assistance programs.
