Assessment of Trace Element Daily Intake Based on Consumption Rate of Foodstuffs in Bandung City

Abstract

Trace elements are required by human body and have a variety role in biochemical functions mostly as catalyst for enzymatic activity in human body. Some trace elements are essential since they are inadequately or not synthesized by human body. The deficiency or excess of those essential trace element may cause disease and be deleterious to health. Since food is the primary source of essential elements for humans and it is an important source of exposure to toxic elements either, the levels of trace elements in consumed food products must be determined. The determination of trace elements content in foodstuffs widely consumed in Bandung city were conducted to assess their daily intake and contribution to the recommended dietary allowance (RDA) values. Food samples were collected from traditional markets spread across five regions of the Bandung city and analyzed using neutron activation analysis (NAA). Quality control of data analysis was assessed using SRM NIST 1567a Wheat Flour and 1568a Rice Flour and gave good results with % recovery, 93.2 -104.8%; and %CV, 3.8-11.6%. A large variability of essential trace elements concentration in all types of foods analyzed were observed. The daily intake of Cr, Co, Mn, Se and Zn were supplied enough by the diet, except for Fe which found that almost all the foods analyzed were not give a satisfying contribution to the RDA value of Fe. These result were expected could provide information of nutritional status of the society and can be a reference for government and related institution to effectively making policies and solution for public health improvement.

Iron Content of Some Popular Cooked Foods Consumed by the Rural School Children in Sri Lanka

“…e obtained values were then compared with the recommended daily allowances (RDA) of children aged 15-16 years. RDA provides the information on average daily intake level that is sufficient to meet the nutrient requirements of nearly all (97-98%) healthy individuals in a particular life stage and a gender group, which is the standard value in assessing the adequacy of daily intake [13]. e values of the RDA for iron for the boys and girls in the 15-16 year age group are presented in Table 1.…”

Essential Minerals of Rice in West Java Indonesia and Its Daily Intake Estimation

“…Several examples of essential minerals are: cobalt (Co), chromium (Cr), iron (Fe), selenium (Se), and zinc (Zn). Cobalt, as a part of vitamin B 12 , stimulates the production of red bloods cells and it is related to the activities of brain and nervous system [2,3]. Chromium is needed to help maintaining normal blood glucose levels/insulin activity [3].…”
