Want to Cut Down on Sugar or Boost Fibre? Small Tweaks Can Make a Big Difference

If you want to make your favorite bakes more wholesome, there’s good news. You can cut back on sugar or increase fiber. Even minor adjustments to tried-and-true recipes can yield big health benefits without sacrificing flavor. Today, I’m taking a classic banana bread recipe and giving it a nutritious makeover. The result? A loaf that’s just as comforting and delicious, but lighter on saturated fat and higher in nutrients.

The Starting Point: A Classic Banana Bread

The original recipe comes from a top-rated banana bread on Cookidoo® (the recipe database for Thermomix®). Here are the standard ingredients:

• 130 g unsalted butter, softened
• 350 g ripe bananas (approx. 4 bananas)
• 150 g caster sugar
• 2 eggs
• 220 g plain flour
• 2 tsp baking powder
• 1 pinch of salt
• 1 tsp bicarbonate of soda
• 100 g buttermilk
• 2 tsp natural vanilla extract

Delicious? Absolutely. But it’s also high in saturated fat, refined sugar, and low in fibre. Let’s give it a nutritious makeover!.

The Nutrition Hack: Smart Substitutions

1. Reduce Saturated Fat

• Original: 130 g butter
• Improved: 65 g butter + 65 g unsweetened applesauce

Why? Applesauce keeps the loaf tender and moist while cutting saturated fat and calories. You still get the richness from some butter, but with far fewer unhealthy fats.

Tip: You don’t even need apple sauce. Just grate or shred an apple and add 65 grams (juice and all) into the batter.

Optional Alternative: Swap the applesauce for low-fat Greek yogurt for a slight tang and added protein.

2. Boost Fibre

• Original: 220 g plain flour
• Improved: 220 g wholewheat flour

Why? Wholewheat flour offers more fibre and nutrients, keeping you feeling fuller for longer.

Optional Alternative: For an extra dose of fibre and healthy fats, add 1 tablespoon of flax seeds or chia seeds.

3. Cut Back on Sugar

• Original: 150 g caster sugar
• Improved: 50 g caster sugar plus the natural sweetness from overripe bananas

Why? Ripe bananas are nature’s candy. By leaning on their inherent sweetness, you can easily halve the added sugar. This reduces the overall glycaemic impact and prevents blood sugar spikes.

4. Choose a Lighter Dairy (or Go Dairy-Free)

• Original: 100 g buttermilk
• Improved: 100 g unsweetened oat milk

Why? Oat milk is cholesterol-free, lower in saturated fat, and plant-based, making it an excellent alternative. It lends a subtle creaminess while helping to reduce overall fat.

5. Add Nutrient Boosters

Walnuts or Pecans: Add 30 g chopped nuts for extra protein, heart-healthy fats, and a satisfying crunch.

Spices & Flavors: A teaspoon of cinnamon or nutmeg adds warmth and depth without extra calories.

Cacao Nibs or Dark Chocolate Chips: A small handful (about 30 g) provides antioxidants. It offers a hint of indulgence, just enough to satisfy your sweet tooth.

Before & After: Nutritional Snapshot

Original (per loaf, 12 slices)

• Calories: ~2830 kcal total (~235 kcal/slice)
• Saturated Fat: ~69 g total (~5.75 g/slice)
• Fibre: ~8.5 g total (<1 g/slice)
• Protein: ~43 g total (~3.6 g/slice)

Improved (per loaf, 12 slices)

• Calories: ~2200 kcal total (~183 kcal/slice)
• Saturated Fat: ~39 g total (~3.2 g/slice)
• Fibre: ~38.5 g total (~3.2 g/slice)
• Protein: ~50 g total (~4.2 g/slice)

You’re not just trimming calories and fat by making these strategic swaps. You’re also significantly bumping up the fibre and protein content. This means a slice of banana bread can go from a quick sugar rush to a more balanced, nutrient-rich snack.

The Revamped Recipe

My Delicious Yet Nutritious Banana Bread

Ingredients

• 65 g unsalted butter (melted or softened)
• 65 g unsweetened applesauce (or Greek yogurt)
• 350 g ripe bananas
• 50 g caster sugar
• 2 eggs
• 220 g wholewheat flour
• 2 tsp baking powder
• 1 pinch salt
• 1 tsp bicarbonate of soda
• 100 g unsweetened oat milk
• 2 tsp natural vanilla extract
• 1 tbsp flax seeds
• 30 g chopped walnuts
• 1 tsp cinnamon

Instructions

1. Preheat the oven to 350 degrees F (180 degrees C). Lightly grease or line a 9×5-inch loaf pan
2. Combine all ingredients in a large bowl and blend with a mixer or a fork until smooth.
3. Pour into prepared loaf tin and bake for 50-60 minutes (180°C) or until a wooden skewer inserted into the centre of the bread comes out clean
4. Allow to cool in tin for 30 minutes before turning out onto a wire rack. Serve warm or allow to cool completely before transferring into a sealable container until ready to eat.

Tips

• make your own apple sauce by grating or finely chopping an apple. You can add the grated apple into the cake batter raw. There is no need to cook the applesauce before adding it to the uncooked cake batter.

Why These Changes Work

1. Flavor Preservation: By using applesauce and overripe bananas, the bread remains moist and flavorful. There is no need for extra butter or sugar.
2. Fibre Boost: Wholewheat flour and flax seeds significantly increase the fibre content, enhances satiety and nutrient density.
3. Healthier Fats: Walnuts and flax seeds provide heart-healthy unsaturated fats, replacing some of the saturated fats from butter supporting heart health
4. Lower Sugar: Less sugar means a lower glycaemic index, preventing blood sugar spikes.

Guilt-Free Indulgence: How to Make Any Recipe More Wholesome

1. Identify the Key Nutritional Concerns: Look at protein, sugar, saturated fat, and fibre content.

2. Make Gradual Swaps: Replace half the ingredient (e.g., butter or sugar) at first, and adjust further in future attempts.

3. Add Nutrient Boosters: Sneak in nuts, seeds, or even vegetables (like grated zucchini or black beans) for extra nutrients.

4. Focus on Flavor: Use natural sweeteners, spices, or extracts to enhance taste without adding calories.
