- Ten enteral nutrition formulas were analyzed to determine their macro and micronutrient (trace element) composition. Protein and fat content ranged between 3.7–8.0 and 1.3–11.9 g / 100 mL respectively. Trace element concentrations ranged between 7.2–15; 2.0–6.8; 0.6–1.6; 1.1–1.5; 0.2 – 0.3; 0.3–1.7 mg / 100 mL for Ca, Mg, Fe, Zn, Cu and Mn respectively; revealing that in many cases they do not match the label values. Trace element bioaccessibility analysis showed dialyzability percentages between 2–16 %. Furthermore, a negative correlation was found between protein content and dialyzed Mg content (r = -0.644, p < 0.05); and between protein content and dialyzed Fe content (r = -0.679, p < 0.05). In contrast, a positive correlation (r = 0.801; p < 0.05) was found between dialyzable Ca and dialyzable Mg, displaying a synergistic interaction between both elements. Finally, a probabilistic assessment showed that the analyzed enteral nutritional formulas meet the Dietary Reference Intakes of all micronutrients assessed.
