Health Benefit-risk Analysis of Locally Cultivated Mango Fruits and Branded Mango Beverages in Adamawa State, Nigeria

Abstract

In this study, the vitamin, nutrient, antinutrient and heavy metal concentrations in Powdered mango fruit juices (sachet brands) (PMFJ), Liquid mango fruit juices (LMFJ), and Fresh or raw mango fruits juices (FMFJ) were assessed toward establishing a tradeoff between their health benefits and potential health risk on consumption. The analysis show the concentration of vitamin C constituting 50-70% and Vitamin A 30-40% by composition relative to other vitamins. The highest concentration of vitamin A and C were observed in the PMFJ, and the LMFJ samples. Relative to the bioavailability of vitamin E, K, B1, B2, B6 and B12, FMFJ contains the highest concentrations compared to PMFJ and LMFJ. The results further show the highest concentration of 0.79 mg/100 g and 6.85 mg/100 g of oxalate and phytate in the FMFJ. The analysis of the mineral contents show Ca accounting for over 50%, with FMFJ containing the highest concentration (57%). The concentration of Mg, Mn, Fe, and Zinc all falls within the acceptable range to constitute any potential risk on consumption. Based on the EDI values, the dietary exposure to lead (Pb) was Bwatanglang et al.; AFSJ, 12(2): 1-10, 2019; Article no.AFSJ.51388 2 observed to be above the oral reference dose (RfD) values set for Pb in edibles. Further appraisal for non-carcinogenic and carcinogenic risk from Pb exposure gives a THQ values of less than one (<1) and a CRI ≤10 -4 . Overall, the results show children to be more at risk for Pb exposure than the adults. From the results, it could suffice to say that unhealthy agricultural practices and possible anthropogenic activities could be the probable reasons for the low level of vitamin A and C in the FMFJ samples. Furthermore, could probably be the contributing factors leading to the increasing use of additives and fortified functional foods to meets population demands and nutritional requirements as observed in the PMFJ and LMFJ samples respectively.
