Few things feel as human as eating well — and few topics online are as noisy, or as risky, when you're facing cancer. Rather than add another set of rules, we've gathered guidance from the institutions your care team already trusts. The most important step isn't on this page: it's a conversation with your own oncology team and a registered dietitian, who know your body, your treatment, and your needs.
For prevention and everyday eating
These focus on evidence-based eating patterns for lowering risk — steady, sensible guidance rather than fad diets.
- American Institute for Cancer Research (AICR) — research-based recommendations on food, nutrition, and cancer risk.
- World Cancer Research Fund — Cancer Prevention Recommendations — the international, evidence-graded guidance.
- American Cancer Society — Diet & Physical Activity — practical, everyday guidance.
Eating during treatment
Treatment can change appetite, taste, and what your body tolerates. These are the patient handbooks clinicians point to for getting through it while staying nourished.
- National Cancer Institute — "Eating Hints: Before, During, and After Cancer Treatment" — the trusted patient handbook.
- American Cancer Society — Nutrition During & After Treatment — managing appetite and side effects through the ups and downs.
- MD Anderson — Appetite & Eating Changes — coping with appetite and taste changes during treatment.
- Memorial Sloan Kettering — Nutrition & Cancer — practical resources and recipes from MSK's clinical dietitians.
Food safety matters more during treatment
When treatment lowers your immune defenses, safe food handling becomes especially important. The National Cancer Institute and American Cancer Society guides above both cover this — it's worth reading closely and reviewing with your care team.
The single best step: an oncology dietitian
No article can account for your specific diagnosis, treatment, and body — but a registered dietitian who specializes in cancer can. If you take one thing from this page, let it be this.
- Academy of Nutrition and Dietetics — Find a Nutrition Expert — search for a registered dietitian (RD), including those who specialize in oncology.
