Anti-nutrient properties

One of many main hindrances to tiger nut improvement and utilization is that it comprises some amount of anti-nutrients resembling tannins, saponins, phytate, oxalates and cyanogenic glycosides that are current in uncooked tiger nut tubers in appreciable portions. If tiger nut tuber is roasted, the amount of alkaloids, steroids and resins within the tubers change into larger than unroasted tiger nut tubers. This is a sign that processing strategies affect antinutritional content material of the tubers. The presence of antinutritional elements (ANF) in meals substances intervene with digestive processes and stop environment friendly utilization of protein.

Consumption of meals that include excessive amount of antinutrients over an extended interval may very well be dangerous to the physique. The dangerous results embrace toxicity, hyperlipidaemia, extreme weight acquire, Hyperglycemia, carotenemia, constipation, kidney stones, physique odour, unhealthy breath, alergles diarrhoea, frequent urination and zits.
