Estimation of daily micronutrient intake of Filipinos.

The Fourth National Nutrition Survey of the Food and Nutrition Research Institute conducted in 1993 showed an increasing prevalence of micronutrient-related diseases in various age groups. Hence, the daily diet consumed by the average Filipino was examined for its nutrient content. A total of 19 regional diet samples were collected and analyzed for phosphorous, iron, zinc, magnesium, manganese, calcium, potassium, and sodium by using inductively coupled plasma atomic emission spectrometry (ICP-AES). Iodine was determined by inductively coupled plasma mass spectrometry (ICP-MS). Benchmark data for the abovementioned micronutrients showed decreased intake values as compared to the recommended dietary allowance established in 1989. The information will be useful in assessing the existing nutritional status so that appropriate nutrient interventions can possibly be put in place.
