Digestive Enzyme Soup —
A Functional Recipe for Low PE-1

Pancreatic elastase-1 (PE-1) is the GI-MAP marker for exocrine pancreatic function. The pancreas produces digestive enzymes — proteases, lipases, amylases — and secretes them into the small intestine to break down protein, fat, and carbohydrates. PE-1 is a specific protease that passes through the gut unchanged, making its stool concentration a reliable proxy for overall pancreatic enzyme output.

Low PE-1 on GI-MAP (<200 µg/g) indicates reduced pancreatic enzyme output. The consequences range from impaired protein digestion (elevated Indican on OAT, undigested food particles in stool) to poor fat absorption (fat-soluble vitamin insufficiency including vitamins A, D, E, K) to carbohydrate fermentation and gas. Many clients with persistent bloating, undigested food in stool, and nutrient insufficiencies despite good dietary intake have a PE-1 finding sitting in their GI-MAP results.

Why food-based digestive support comes first

Before reaching for pancreatic enzyme supplements — which are appropriate when PE-1 is significantly low and symptoms are impacting quality of life — it is worth optimising the physiological conditions that support digestive enzyme function:

The recipe — and why each ingredient is there

This soup is designed to be eaten as a starter or light meal, particularly beneficial before a larger meal when digestive capacity is a concern. The apple cider vinegar ritual before the meal is part of the protocol, not optional.

Bone broth base — glycine, collagen, gut repair

Proper bone broth (4–6 hours simmered, not stock cubes) provides glycine, proline, hydroxyproline, and collagen peptides that directly support gut epithelial integrity. Glycine specifically supports bile acid conjugation in the liver and has demonstrated gut barrier-protective effects. The warm liquid form is inherently easier to digest than solid food — reducing the digestive burden while providing therapeutic compounds.

Fresh ginger — gastric motility and anti-inflammatory

Ginger contains gingerols and shogaols that stimulate gastric motility and accelerate gastric emptying — moving food appropriately through the stomach and reducing the fermentation and bloating that comes with delayed gastric emptying. Anti-inflammatory activity in the gut lining is an additional benefit when mucosal inflammation is contributing to poor enzyme function.

Bitter greens (radicchio, endive, or dandelion leaf) — bile stimulation

The bitter taste activates bitter receptors on the tongue and throughout the digestive tract (TAS2R receptors), triggering bile release from the gallbladder and digestive secretion throughout the GI tract. This is the oldest digestive medicine there is — aperitifs, digestivi, and bitter herb traditions across every food culture are empirically derived applications of the same mechanism. A small amount of bitter greens, eaten first, prepares the digestive cascade for what follows.

Leek and celery — prebiotic and anti-inflammatory

Leek provides fructooligosaccharides (FOS) — prebiotic fibre feeding Lactobacillus and Bifidobacterium populations. In low-PE-1 contexts, fibre should be cooked and soft rather than raw to reduce the digestive demand. Celery provides apigenin — an anti-inflammatory flavonoid with documented activity in gut mucosal tissue.

Turmeric and black pepper — anti-inflammatory and bioavailability

Curcumin from turmeric has direct anti-inflammatory activity in intestinal tissue and supports bile flow. Piperine from black pepper increases curcumin bioavailability by approximately 2000% by inhibiting glucuronidation — always combine them. Fat in the broth further enhances curcumin absorption (it is fat-soluble).

The recipe

Serves 2 as a starter or light meal. Preparation: 15 minutes. Cooking: 35 minutes.

Ingredients: 750ml good quality bone broth (chicken or beef) · 1 leek, white and light green parts, sliced · 2 sticks celery, sliced · 3cm fresh ginger, grated · 2 garlic cloves, finely chopped · Small handful radicchio or endive, shredded (added at the end) · ½ tsp turmeric · Good pinch black pepper · 1 tbsp extra virgin olive oil · Sea salt to taste · Optional: small amount cooked chicken, shredded, added at end

Method: Warm the olive oil in a wide pan over medium heat. Add leek and celery and cook gently for 8 minutes until softened but not coloured. Add garlic and ginger and cook for 2 minutes. Add turmeric and black pepper and stir for 30 seconds. Pour in bone broth, bring to a gentle simmer, and cook for 20 minutes. Just before serving, add the shredded bitter greens — radicchio or endive — and stir through. They should wilt slightly but retain some texture and bitterness. Season with sea salt. Serve immediately.

Clinical note on eating this: Sit down. No screens, no work, no rushing. The cephalic phase of digestion — triggered by the act of smelling, seeing, and attending to food — is worth more than any supplement in a digestive soup. The parasympathetic state required for digestion is not an optional extra.
