Small, chewy, slightly sweet tubers — eaten dried, soaked, or as tiger nut milk (kunu aya). One 1oz (28g) serving provides 10g fiber (40% DV — extraordinary), 9g resistant starch, 7g fat (mostly MUFA — oleic acid), 4g protein, 8% DV iron, and a complete profile of minerals. The resistant starch content (9g/oz) is the highest of any commonly consumed food in absolute terms.
Available at West African markets. Tiger nut snacks and flour increasingly at health food stores online. Kunu aya sold at Nigerian and West African food vendors.
The resistant starch content of tiger nuts is clinically remarkable. Resistant starch resists digestion in the small intestine and reaches the colon intact, where it becomes the preferred substrate for Bifidobacterium, Faecalibacterium prausnitzii, and Akkermansia muciniphila — the three gut bacteria most associated with metabolic health, anti-inflammation, and longevity. Resistant starch fermentation produces butyrate — the primary fuel for colonocytes (colon lining cells) and one of the most potent anti-colon-cancer compounds documented. Multiple human feeding studies demonstrate resistant starch significantly improves insulin sensitivity and reduces post-meal glucose responses — making tiger nuts the most powerful dietary tool for insulin resistance management through gut microbiome modification. The traditional West African drink kunu aya (tiger nut milk) is a natural probiotic and prebiotic beverage that sustained communities for thousands of years.
Dried: soak in water 24-48 hours, eat as a chewy snack. Tiger nut milk (kunu aya): soak tiger nuts 24h, blend with water, strain, add cinnamon and ginger.
