When you’re on a cancer journey, every choice you make plays a significant role in supporting your overall wellbeing. One often-overlooked aspect is blood sugar management during cancer treatment. Glucose, a vital energy source for our bodies, can influence everything from energy levels to mood and even the effectiveness of certain treatments. Keeping your blood sugar stable isn’t just about feeling better day-to-day – it can also support your body’s ability to heal and respond to treatment.

Here, we’ll explore why managing blood sugar matters and share practical, natural ways to help you maintain balanced glucose levels.

Why Managing Blood Sugar Matters During Cancer Treatment?

During cancer treatment, your body faces increased stress and metabolic changes, which can sometimes lead to blood sugar imbalances. High glucose levels can contribute to inflammation, fatigue, and even hinder treatment outcomes. On the other hand, stable blood sugar levels can:

• Support consistent energy levels
• Improve mood and focus
• Help maintain a healthy weight
• Enhance overall wellbeing and treatment response

Here are some effective, science-backed ways to help keep your blood sugar in check:

1. Eat Balanced Meals for Stable Blood Sugar

Eating balanced meals helps maintain steady glucose levels. Aim to include complex carbohydrates, healthy fats and lean proteins in every meal. This balance slows glucose absorption and prevents blood sugar spikes.

Example: Combine quinoa (a complex carb) with roasted chickpeas and avocado for a nourishing, glucose-friendly meal that supports blood sugar management during cancer treatment.

2. Boost Blood Sugar Control with High-Fibre Foods

Fibre, especially soluble fibre, slows the absorption of sugar into the bloodstream. This helps prevent sudden glucose spikes and supports digestive health.

High-fibre foods to try:

• Chia seeds
• Flaxseeds
• Leafy greens (like spinach and kale)
• Legumes (beans, lentils)

Aim for 25–30 grams of fibre daily to help regulate glucose naturally.

3. Avoid Processed Sugars to Prevent Glucose Spikes

Refined sugars and simple carbs can cause rapid glucose spikes and crashes, which may lead to fatigue and mood swings. Instead, reach for natural alternatives like raw honey or dates in moderation. Whole fruits, thanks to their fibre content, are a healthier option for satisfying a sweet tooth.

4. Time Your Carbohydrates for Better Glucose Control

Eating most of your carbohydrates earlier in the day can help your body manage glucose better, as insulin sensitivity is higher in the morning. On more active days, you can slightly increase your carbohydrate intake to fuel your body, while reducing it on rest days.

5. Move After Meals to Improve Insulin Sensitivity

Gentle physical activity after eating helps regulate blood sugar levels by promoting glucose uptake in your muscles.

Try: A 10–15 minute walk after each meal to improve insulin sensitivity and support digestion.

6. Incorporate Natural Glucose-Lowering Foods

Some foods naturally help stabilise blood sugar levels. Including these in your meals can give your body an extra boost:

• Apple cider vinegar: Add a splash to salads
• Cinnamon: Sprinkle on porridge or yogurt
• Fenugreek and berberine: Discuss with your healthcare provider before incorporating supplements

7. Stay Hydrated to Support Glucose Balance

Dehydration can cause blood sugar levels to rise. Aim for 8–10 cups of water daily to stay hydrated. Adding a slice of lemon or a pinch of sea salt can help improve electrolyte balance.

8. Improve Sleep Quality to Help Regulate Glucose Levels

Poor sleep can disrupt insulin sensitivity and lead to glucose imbalances. Prioritise 7–9 hours of restful sleep each night by sticking to a consistent bedtime and creating a relaxing evening routine.

9. Manage Stress for Better Blood Sugar Control

Chronic stress increases cortisol levels, which can raise blood sugar. Incorporate stress-reducing practices into your daily routine:

• Meditation
• Yoga
• Deep breathing exercises

10. Track Blood Sugar Levels for Personalised Insights

Understanding how your body responds to different foods and activities can be empowering. Using a continuous glucose monitor (CGM) or checking blood sugar levels regularly can provide valuable insights to tailor your lifestyle for better blood sugar management during cancer treatment.

Supporting Your Body with Mindful Choices

Regulating blood sugar during your cancer journey isn’t about strict dieting or deprivation. It’s about making sustainable, nourishing choices that support your body and mind. By incorporating these strategies into your daily routine, you can boost your energy levels, improve your mood, and help your body respond more effectively to treatment.
