Wholegrain Rice Cakes with Avocado and Smoked Salmon – A Gut-Friendly Recipe

Preparation Steps

1. Prepare the avocado. Halve the avocado, remove the stone, and scoop out the flesh with a spoon. Place it in a small bowl. Squeeze over half the lemon juice straight away, then mash roughly with a fork — you're looking for a creamy but slightly rustic texture, not a smooth purée. Add the olive oil, a turn of black pepper, and stir gently. Taste and adjust the acidity to your liking.

2. Prepare the toppings. Rinse and dry the rocket leaves (or baby spinach). Cut the cucumber into thin rounds. Pick the leaves from a few sprigs of dill, or finely chop the chives. Set everything out in front of you, ready to assemble.

3. Assemble the rice cakes. Lay the four wholegrain rice cakes flat on a board or large plate. Spread the mashed avocado generously over each one, leaving a small border around the edges to prevent the toppings from sliding off.

4. Add the salmon and vegetables. Lay 1 to 2 slices of smoked salmon over each rice cake, folding them slightly to add volume and avoid a flat, dense layer. Arrange 2 to 3 cucumber rounds and a few rocket or baby spinach leaves on top of each one.

5. Finish and serve. Squeeze the remaining lemon juice over all four rice cakes for a fresh hit of acidity and to help protect the avocado from browning. Scatter over the chopped dill or chives. Add a small pinch of flaky sea salt if needed, bearing in mind that smoked salmon is already quite salty. Serve immediately.

Why This Recipe Is Gut-Friendly

This recipe draws its digestive value from the complementary nature of its ingredients, each contributing something specific to your gut.

Avocado — the star ingredient for your microbiome. This is the most interesting ingredient from a gut health perspective. Rich in dietary fibre (roughly 6–7 g for a whole avocado) and monounsaturated fatty acids, it helps support regular transit and feeds certain beneficial bacteria in the colon. Recent clinical trials have shown that daily avocado consumption can favourably shift bacterial diversity in the gut and increase the production of short-chain fatty acids — protective metabolites for the intestinal lining.

Smoked salmon — an anti-inflammatory ally. It doesn't act as a probiotic, but its marine omega-3s (EPA and DHA) play a well-established role in moderating low-grade intestinal inflammation. It also provides highly digestible protein that promotes satiety without overloading digestion. One thing to bear in mind: smoked salmon is naturally high in salt, so choose minimally processed slices and go easy on added salt elsewhere in the recipe.

Wholegrain rice cakes — a neutral, easy-to-digest base. They don't feed the microbiome in any significant way, but their main asset is their excellent digestive tolerance: low in fermentable compounds and easy to digest, they suit most sensitive profiles. They also offer slightly more fibre and minerals than their white rice equivalents. Paired with avocado and salmon, they help blunt the blood sugar spike that a plain rice cake eaten alone might cause.

The lemon and fresh herbs round out the recipe in terms of flavour, reducing the need for salt or rich sauces — which helps preserve the overall digestibility of the dish.

IBS Adaptations and Low-FODMAP Profile

This recipe is naturally close to a low-FODMAP profile, provided you keep an eye on the avocado portion, which is the main point to watch.

• Avocado: FODMAP tolerance depends on portion size. A serving of around 30 g (approximately 2 tablespoons of flesh) is generally considered low-FODMAP according to reference data. If you are in a strict elimination phase, limit yourself to this amount per rice cake, or replace the remainder with a light mash of peeled cucumber blended with a drizzle of olive oil and lemon juice to preserve the creamy texture.
• Rice cakes: generally well tolerated in IBS — simply check the ingredient list to avoid varieties containing fructose, honey, or added sweetened flavourings.
• Smoked salmon: compatible in small portions from a FODMAP perspective. Sensitivity to smoked or heavily salted foods is more often a matter of individual tolerance than a FODMAP issue per se.
• Avoid if in an elimination phase: garlic powder, onion, teriyaki or sweet-style sauces, large amounts of flaxseed or chia seeds as a topping.
• Well-tolerated additions: cucumber, rocket, baby spinach, dill, chives, lemon juice, olive oil.

Nutritionist Tips to Go Further

• Boost your daily fibre intake around this recipe by pairing it with a vegetable soup at lunch or a plain yoghurt with a little fruit in the morning. Since rice cakes are low in fermentable fibre, it's the balance of your whole day that matters most for your microbiome.
• Vary the base according to your tolerance: wholegrain rye crackers, slices of wholemeal sourdough, or thick cucumber rounds can replace the rice cakes for a more diverse and more prebiotic fibre intake.
• Eat this recipe promptly after assembling: avocado oxidises quickly and the rice cake softens as it absorbs moisture. If you want to prepare ahead, store the mashed avocado separately in a bowl covered with cling film pressed directly onto the surface, with a squeeze of lemon juice.
• As an evening meal, reduce the smoked salmon portion if you're sensitive to salt later in the day, and opt for a generous serving of avocado for satiety and digestibility.
