Macro-nutrients in edible parts of food crops in the region of Moanda, Gabon
Abstract: The assessment of nutritive foodstuffs quality is an important step in the estimation of dietary intake of metals. This study aimed to assess accumulation and the daily intake of macro-elements magnesium, calcium, potassium and sodium in edible parts of plants grown in Moanda area. The ranges of concentrations were 246 - 5645 mg/kg, 1167 - 35105 mg/kg, 158 - 12563 mg/kg and 88 - 795 mg/kg for Mg, Ca, K and Na, respectively. Mg and K levels were significantly higher in fruits than in tubers. The trend of accumulation in the edible parts of plants was generally: Ca > K > Mg > Na. The daily intakes of Mg and Ca were the highest and indicated food crops in Moanda had a good nutritive quality.
