Nutrition is shifting from supportive care to a central role in cancer therapy. Advances in genomics, metabolomics, and microbiome science now enable personalized diets tailored to each patient’s biology. These strategies aim to improve treatment response, reduce side effects, and support overall health. Researchers are testing microbiome-focused diets with prebiotics and probiotics, as well as medical nutrition formulas enriched with omega-3 fatty acids and antioxidants to reduce inflammation and maintain strength during treatment.
Metabolic approaches like ketogenic diets may help stress cancer cells while protecting normal tissues. Symptom-targeted methods—such as cryotherapy for mouth sores and ginger for nausea—are also improving patient comfort. In addition, plant compounds like curcumin, green tea extract, and resveratrol are being studied for potential anti-cancer effects.
Digital tools and AI now allow real-time monitoring and adjustment of nutrition plans. Key nutrients such as vitamin D, selenium, and omega-3s may further enhance immune response and improve outcomes, especially alongside immunotherapy.
