Abstract: This study was conducted to determine the nutritional and anti-nutritional content of cassava tubers and leaves in Jos North Local Government Area of Plateau state, Nigeria. Proximate analysis was determined by standard method for the percentage moisture content, ash content, crude protein, crude fibre and carbohydrate. Elemental analysis was determined using AAS and UV-Spectrophotometer. The anti-nutritional constituents determined includes; cyanogenic glycosides, trypsin inhibitor, phytic acid, tannins and oxalate. The tubesr have moisture content (10.57±0.2%), ash content (2.4±0.001%), crude protein (4.8±0.30%), crude fat (2.4±0.02%), crude fibre (3.9±0.08%), carbohydrate (80.54±2.40%), calcium (29.31±0.14%), potassium (8.94±0.04%), sodium (38.7±0.20%), magnesium (23.5±0.10%), phosphorus (0.150±0.004%), cyanogenic glycosides (2.06±0.008mg/L), trypsin inhibitor (4.28±0.03TUI/mg), phytate (31.02±0.34mg/100g), tannins (3.64±0.009mg/100g), oxalate (1.29±0.029g/100g) and the leaves showed moisture content (5.86±0.01%), ash content (1.6±0.01%), crude protein (5.6±0.08%), crude fat(1.8±0.04%), crudefibre (4.6±0.01%), carbohydrate (75.9±0.60%), calcium (38.65±1.35%), Potassium (13.10±0.12%), sodium (58.8±0.58%), magnesium (24.80±0.20%), phosphorus (0.280±0.001%), cyanogenic glycosides (7.31±0.098mg/L), trypsin inhibitor (10.74±0.012TUI/mg), phytate (58.47±0.403mg/100g), tannins (78.67±0.471mg/100g), oxalate (1.61±0.084g/100g).

I.INTRODUCTION
Cassava (Manihot esculentus) is a perennial woody shrub with an edible root. It grows in tropical and subtropical regions and is known by different names in different parts of the world. (Adeyanju and Emesi,2019; Emesi et al.,2019). Cassava is a highly drought-tolerant crop with the ability to grow on marginal lands where cereals and other crops do not grow well. Cassava is the third largest source of food carbohydrates in the tropics, after rice and maize (Emesi et al.,2019).Food is made up of all nutrients which is needed for growth and maintenance of our body. A balanced diet supplies all nutrients in adequate amount to maintain optimal health. Anti-nutrients are natural or artificial compounds that interfere with the absorption of nutrients. Phytate and oxalates easily forms insoluble complexes with copper, iron and calcium. Tannins chelate metals and reduce the absorption of these
