Chemo Snacks: What are the best foods to eat while on chemotherapy

Written By Lotte May

When you or a loved one is navigating cancer treatment, finding the right snacks becomes a top priority. The goal is to find foods that are gentle on the stomach, nutrient-dense, and easy to prepare when fatigue sets in. Let’s explore research-backed snack ideas designed to make the chemotherapy process a little easier.

The Science of the BRAT Diet for Nausea

In clinical settings, oncology dieticians often recommend the BRAT diet (Bananas, Rice, Applesauce, and Toast) during peak nausea periods. These foods are low in fibre and high in binding properties, making them exceptionally gentle on the digestive tract. While the BRAT diet isn't a long-term solution, it acts as a gastric bridge to help you maintain calorie intake when your stomach is most sensitive.

Gentle Snacks for Sensitive Stomachs

When nausea strikes, bland and easily digestible snacks are your best defence. These options provide energy without overtaxing your digestive system:

• Plain Rice Cakes & Crackers: Light, portable, and excellent for settling a restless stomach.
• Bananas: High in potassium, which can be depleted during treatment, and naturally "packaged" for on-the-go snacking.
• Applesauce Pouches: Provides gentle hydration and natural sweetness without the effort of chewing heavy fruit.
• Ginger Chews: Ginger contains gingerols, natural compounds proven to soothe the digestive system and alleviate nausea.
• Plain Yogurt: A great source of probiotics to help maintain gut health during treatment.

Hydration and Electrolyte Support

Staying hydrated is vital, but chemotherapy can sometimes make plain water taste metallic. To stay hydrated:

• Infused Water: Add cucumber, mint, or lemon to mask the metallic taste.
• Coconut Water: A natural source of electrolytes like magnesium and potassium.
• Fruit Ice Pops: Excellent for soothing a sore mouth (mucositis) while providing hydration.

Protein-Rich Snacks for Energy

Treatment can zap your energy, so fatigue management through protein is essential for muscle maintenance:

• Greek Yogurt: High in protein; try topping with honey for a quick calorie boost.
• Nut Butters: Pair peanut or almond butter with crackers for a balance of healthy fats and protein.
• Hummus & Veggies: A great plant-based option that is easy to graze on throughout the day.

Indulgent Yet Healthy Treats

If your appetite allows, a small sweet treat can provide a much-needed emotional boost. Opt for items that offer nutrients alongside the sweetness:

• Dark Chocolate: High in antioxidants; try pairing with almonds for added crunch.
• Baked Apple with Cinnamon: Soft, warm, and easy to digest while providing fibre.
• Oatmeal Cookies: A comforting snack that provides slow-release energy from oats.
