Abstract:

 Background: The work involves the determination of the glycemic index, glycemic load and mineral constituents of a commonly consumed mixed diet that are significant in diabetic and good health management. Objectives: Literature is scarce on the glycemic index, glycemic load and the mineral elements of the popular mixed diet of ‘garri’ and tilapia fish commonly consumed in Nigeria. The paper therefore aims to fill this gap. Methods: Twenty healthy individuals were subjected to overnight fast for a minimum of 12 hours (10 control and 10 test subjects).The glycemic index was determined by making use of the mean of 10 healthy individuals who were fed with 50g carbohydrate equivalent of the test food and their postprandial responses were measured with a standardized glucometer. The 10 controls were treated as the test subjects but were fed with 50g of powered glucose. The glycemic index and glycemic load for test food were calculated by making use of standard methods. The proximate analysis of the test food was also determined by standard methods. The elemental constituents of the test food were determined with an Inductively Coupled Plasma Mass Spectrophotometer. The results were analyzed by using ANOVA and expressed as mean ±SEM of duplicate determinations. Results: The results indicate that the GI and GL of the test food were 62 and 35 respectively, the proximate analysis showed that the nutrient compositions ranged between 1.21±0.0 (fiber) and 55.74±5.73% (carbohydrate), and the elemental constituent concentrations ranged between 0.17±0.02mg/kg (cadmium) and 5990.26±119.19mg/kg (calcium) respectively. Conclusion: The mixed food has a medium glycemic index and a high glycemic load and could be consumed by non-diabetics and diabetics. In additionthe 20 elements detected are needed in the daily dietas they play significant roles in human physiology and metabolism.
