Total and dialysable magnesium and calcium levels and corresponding dialysabilities were measured in duplicate meals (n = 108) during 36 consecutive days. The interaction exerted by other nutrients and energy on them was also performed. Total mean magnesium and calcium fractions of 113.9 +/- 98.3 and 337.2 +/- 278.9 mg/meal respectively, were found. The Mg and Ca levels supplied by meals are positively (p < 0.05) correlated with macronutrient contents (carbohydrates and proteins). The mean dialysable Mg and Ca fractions were 56.9 +/- 36.3 and 127.4 +/- 112.3 mg/meal (50.4 +/- 13.2 and 37.8 +/- 10.7% as dialysabilities, respectively). Total Mg and Ca levels are significantly correlated with corresponding element dialysabilities (p < 0.05). For both minerals, significant correlations between their total and dialysable fractions and between their dialysable level and dialysabilities were noted (p < 0.01). The mean Mg and Ca daily dietary intakes (DDI) were 341.7 +/- 68.0 and 1,011.6 +/- 424.4 mg/day, respectively. For Ca and Mg the existence of similarities in their behaviour in meals and absorptive processes has been found. Duplicate meals with raw vegetables are good sources of bioaccessible Mg. High Ca dialysability has been found in the analysed meals. The fish and products constitute a good source of bioaccessible Ca. Mg, Ca, zinc, and chromium levels enhanced significantly the Mg dialysability. The Ca dialysability rose significantly with dialysable Ca and chromium fractions (p < 0.05).

Background and objectives: Fe, Zn, Cu, and Mn contents as well as bioaccessible fractions of eight rice varieties were analyzed in order to evaluate them nutritionally. Findings: Total trace element concentrations ranged between 5.90 and 15.3 mg/ kg for Fe, 8.82-12.9 mg/kg for Zn, 1.45-5.59 mg/kg for Cu, and 2.45-13.6 mg/ kg for Mn. Brown rice presented the highest trace element contents and at the same time the lowest bioaccessibility. A negative significant statistical correlation was found between dietary fiber and Mn bioaccessibility (r = −0.872; p < 0.01).Significant statistical negative correlations were found between vegetable proteins of rice and trace elements bioaccessibility. Conclusions: A probabilistic assessment (@Risk) used to determine the contribution of DRI for Fe, Zn, Mn, and Cu through the intake of 150-200 g of boiled rice showed that this food can be a proper source of Cu and to a lesser extent Mn but not in the case of Fe and Zn. Significance and novelty: The present study develops a probabilistic model to evaluate the contributions to the DRIs of these micronutrients, from data of rice varieties consumption and their bioaccessibility-total content.
