Top 10 Foods to Fight Cancer-Related Fatigue

Written By Lotte May

When you are navigating cancer treatment, food is more than just fuel, it is medicine! Selecting foods high in protein, healthy fats, and fibre can help stabilise your energy levels and combat the bone-deep exhaustion often caused by chemotherapy and radiation.

The Science: The Glycemic Index and Energy Crashes

To manage fatigue, it is vital to understand the Glycemic Index (GI). High-sugar snacks and caffeine provide a rapid spike in blood glucose, followed by a sharp crash that leaves you feeling more depleted than before. By choosing Low-GI foods—like lentils, nuts, and oats—you ensure a slow, sustained release of glucose into your bloodstream. This prevents the energy rollercoaster and helps your body maintain the cellular stamina needed for tissue repair during cancer treatment.

Top 10 Energy Foods to Fight Fatigue

If you are struggling with a low appetite, grazing on these nutrient-dense snacks throughout the day can provide a steady stream of energy while reducing nausea.

Hummus & Tahini: Chickpeas are rich in iron and B vitamins, while tahini adds essential minerals like magnesium and zinc for cellular health.
Apples with Nut Butter: The fibre in apples slows the absorption of natural sugars, while peanut or almond butter adds healthy fats for long-lasting satiety.
Greek Yogurt: A powerhouse of protein and calcium. The simple sugars provide a quick boost, while the protein sustains it.
Bananas: Packed with potassium and Vitamin B6, which helps your body metabolise carbohydrates into usable energy.
Eggs: Contain leucine, an amino acid that triggers energy production in the cells.
Iron-Rich Foods: Anaemia is a leading cause of fatigue. Prioritise lean meats, seafood, spinach, and iron-fortified cereals to support red blood cell production.
Unprocessed Whole Foods: Avoid packaged snacks. Eating fresh reduces the workload on your digestive system, leaving more energy for recovery.
Nuts and Seeds: A perfect portable snack for hospital waits, providing a balance of omega-3 fats and protein.
Cruciferous Vegetables: Broccoli and kale are rich in vitamins A, E, and K, which support your immune system and gut health.
Lentils and Beans: These are slow-burn complex carbohydrates that provide iron and fibre to keep your energy levels level all afternoon.

The Best Teas for Focus and Energy

If you are cutting back on caffeine, herbal teas are a fantastic alternative. Many contain adaptogens that help the body manage stress and cognitive fog:

Peppermint: Stimulates the central nervous system and improves concentration.
Ginger: Aids digestion and provides a natural, spicy wake-up call.
Lemongrass & Rooibos: Caffeine-free options that are rich in antioxidants.
