Asparagus is one of the richest natural sources of inulin — the same prebiotic fibre found in garlic and onions. A single serving delivers 2-3 grams of inulin that passes through your upper digestive tract intact, arriving in the colon where Bifidobacteria ferment it into short-chain fatty acids. It also contains glutathione, one of the body's most important antioxidants.
Why it matters
Inulin Rich
2-3g of inulin per serving — a direct fuel source for beneficial Bifidobacteria.
Glutathione Source
Contains the body's master antioxidant, supporting liver detoxification and cellular repair.
Folate Dense
One of the best vegetable sources of folate, essential for DNA synthesis and cell division.
Anti-inflammatory
Contains saponins and flavonoids that reduce systemic inflammation.
How to eat it
Roast with olive oil and sea salt for 12 minutes at 200°C. Steam lightly and add to grain bowls. Shave raw into salads with lemon and parmesan. Grill alongside salmon for a prebiotic-protein combination.
Asparagus inulin has been shown to significantly increase faecal Bifidobacterium counts within two weeks of regular consumption, with concurrent increases in butyrate production.
