February marks World Cancer Month, and this year’s spotlight colour is orange — vibrant, energising and full of hope.
As a dietitian working closely with oncology patients, I love this theme, because orange (and its rainbow cousins red and yellow) represent some of the most powerful phytonutrient-packed foods we can include to support people before, during, and after cancer treatment.
Let’s dive into how these sunshine colours can brighten both your plate and your health.
Why These Colours Matter in Oncology Nutrition
Cancer treatment is tough — appetite changes, taste alterations, fatigue, weight loss, inflammation, and digestive side-effects can make eating feel like hard work.
That’s exactly why orange, red and yellow foods are nutritional superheroes. They are:
• Naturally soft, juicy and easy to eat
• High in antioxidants that support cellular repair
• Packed with vitamins A & C that help immune function
• Rich in carotenoids (like beta-carotene, lutein & lycopene)
• Often well tolerated even during nausea or low appetite
• Versatile — they work in smoothies, soups, purées, energy-dense snacks, and soft meals
ORANGE FOODS – The Repair Crew
Orange foods are rich in beta-carotene, a precursor to vitamin A — crucial for skin integrity, immune strength and the healing of mucosal surfaces (especially important for patients with mucositis or radiation dermatitis).
Great choices include:
• Carrots (raw, roasted, juiced or puréed)
• Sweet potato & butternut
• Pumpkin
• Orange peppers
• Mango, papaya, apricots, nectarines
• Orange lentils (gentle on the gut)
Oncology-friendly ideas:
• Creamy butternut soup with added olive oil for extra calories
• Mango + yoghurt + honey smoothie for easy sipping
• Roasted sweet potato mash — nutrient-dense, soft, comforting
• Puréed carrot & ginger — soothing on tender mouths
RED FOODS – The Anti-Inflammation Squad
Red foods contain lycopene, anthocyanins, and vitamin C — powerful antioxidants that help counter oxidative stress that often increases during chemo and radiation.
Top red picks:
• Tomatoes (raw, cooked, puréed)
• Red berries (strawberries, raspberries)
• Watermelon
• Red apple (peeled if needed)
• Red papaya
• Beetroot (great for colour & calories when roasted or blended)
• Red peppers
Oncology-friendly ideas:
• Strawberry & banana blender ice cream (high-calorie, cold, soothing)
• Tomato & basil soup enriched with cream or olive oil
• Watermelon cubes or blended juice — refreshing for nausea
• Roasted beetroot purée stirred into mashed potato for extra colour & nutrients
YELLOW FOODS – The Energy Boosters
Yellow foods contribute vitamin C, bromelain (from pineapple), and slow-release carbohydrates that support energy during treatment.
Yellow favourites:
• Pineapple
• Bananas (easy to digest, gentle on the gut)
• Yellow peppers
• Corn (soft in soups or mashed)
• Yellow peaches
• Turmeric (anti-inflammatory boost)
Oncology-friendly ideas:
• Banana + peanut butter smoothie for weight maintenance
• Pineapple sorbet for metallic taste changes
• Yellow pepper & corn soup
• Golden milk with turmeric (if tolerated)
When appetite is low, colour becomes a powerful tool — visually appealing foods stimulate appetite and make meals feel more inviting. A Sunshine Plate focuses on:
• 1–2 orange foods for carotenoids
• 1 red food for antioxidants
• 1 yellow food for energy
• Healthy fats (olive oil, nut butters, avocado if tolerated) to boost calories
• Soft textures to make eating easier
“If it looks like a sunset, it probably loves your cells.”
Encouraging patients to “eat the sunset” makes it fun, memorable and helps them visually aim for a supportive, colourful plate — especially during tough treatment weeks.
Oncology nutrition isn’t about perfection — it’s about support, comfort and nourishment in whatever form is manageable. Orange, red and yellow foods are nutritional powerhouses that bring:
• Colour
• Energy
• Healing nutrients
• Comfort
• Joy
And joy, truly, is medicine too.
