Abstract:
Dietary supplements and agricultural byproducts were characterized by neutron activation analysis. The nutritional potential of supplements was evaluated according to alternative and commercial categories, using analysis of variance and cluster analysis, and recommended dietary intake for children. The results indicated statistically significant differences between both categories for the elements Cs, K, Na, and Rb. For the nutritional elements Ca, Co, Fe, K, Na, and Zn, the categories were similar in cluster analysis. The similarity between elemental profiles of alternative supplements and agricultural byproducts was calculated using a dissimilarity matrix, showing that rice and wheat are the predominant ingredients.
