“…In humans, a wide range (10 -75%) of magnesium absorption rates has been reported (Danielson et al, 1979;Schwartz et al, 1984;Schuette et al, 1990;Fine et al, 1991;Brink & Beynen 1992;Lönnerdal et al, 1993;Lönnerdal, 1995;Benech & Grognet, 1995;Serfaty-Lacrosniere et al, 1995;Knudsen et al, 1996;Fairweather-Tait & Hurrell, 1996;Andon et al, 1996;Abrams et al, 1997;Sojka et al, 1997) and have been recently reviewed (Ekmekcioglu, 2000); higher values have been observed in animal studies (Lönner-dal et al, 1993;Lazichi Lakshmanan et al, 1984;Kikunega et al, 1995). In these previous studies, various protocols have been applied, including balance studies (Lönnerdal et al, 1993;Lönnerdal, 1995;Serfaty-Lacrosniere et al, 1995;Andon et al, 1996), true bioavailability studies with stable (Schwartz et al, 1984;Schuette et al, 1990;Knudsen et al, 1996;Sojka et al, 1997) and have been recently reviewed (Ekmekcioglu, 2000); higher values have been observed in animal studies (Lönnerdal et al, 1993;Lazichi Lakshmana et al, 1984;Kikynega et al, 1995).…”

Objective: To assess magnesium enteral absorption from a magnesium-rich mineral water. Design: Experimental study. Setting: Department of Nuclear Medicine, Brugmann Hospital, Brussels, Belgium. Subjects: Ten healthy male volunteers in the age range 25 -42 y. Intervention: Each subject completed two sessions in a random order. At one session, they received an oral load of 300 ml of water (containing 1.2 mmol Mg), traced with 28 Mg, and at the other session they received an intravenous injection of 28 Mg, in order to take into account the metabolism of endogenous magnesium. The dietary consumption was further noted on a weekly diary. Results: The mean bioavailability was 59.1% (s.d. AE 13.6). Magnesium absorption and age were significantly inversely correlated (r ¼ 70.68, P ¼ 0.035). Conclusion: Magnesium-rich mineral water is a reliable source of magnesium. Our observation of decreased magnesium absorption with age deserves further investigations. Sponsorship: The study was sponsored by SEV,

“…Ca, for example, is responsible for several metabolic functions, such as blood coagulation muscle contraction regulation, hormone secretion, and neurotransmission. [9][10][11] Mg is a macroelement that participates in energy metabolism and is involved in protein synthesis. 11,12 Cu has a crucial role in cell physiology, acting as a cofactor in several enzymatic reactions.…”

“…13,14 Fe has participation as a cofactor of several enzymes in the Krebs cycle is particularly important. 9,15 Determination of the total levels of inorganic constituents, such as Ca, Fe, K and P in food, is crucial to assess the possible impact of the food on human health. Various elements in cassava and flour samples from various countries have been determined using flame atomic absorption spectrometry (FAAS), [16][17][18][19] graphite furnace atomic absorption spectrometry (GF AAS), 20,21 inductively coupled plasma-optical emission spectrometry (ICP OES) [22][23][24][25] and inductively coupled plasma mass spectrometry (ICP-MS) [26][27][28][29] .…”

Resumo:The concentrations of Ca, Cu, Fe, K, Mg, Mn, P and Zn in 10 commercially available cassava flours (Manihot esculenta Crantz, Euphorbiaceae) were determined using inductively coupled plasma optical emission spectrometry (ICP OES). The elements were found in descending order of concentration, as K > Ca > P > Mg > Fe > Cu > Zn > Mn. Based on the recommended daily intake for adults, the values showed that 10 g day -1 cassava flour provides 5.3% of the daily intake of Cu, 0,5-1.2% for Fe, 0.5% for Ca, 0.9-1.2% for Mg, 0.6-0,8% for Mn, 0.6% for P, 0.2% for K and 0.2-0.3% for Zn. Based on the RDIs (Recommended Daily Intake) of the elements studied, the results indicate that cassava flour contains several essential elements, and the levels found in the cassava flours presents no risk to the human health. With the results of the multivariate analysis, it was possible to locate information about clusters and dissimilarities between the samples and between the variables, as well as to provide useful information for future studies on quality control and genetic improvement of cassava with better nutritional values.

“…Anemia kekurangan zat besi juga menyebabkan masalah serius lain seperti gangguan kemampuan belajar pada anak, peningkatan kerentanan terhadap infeksi dan mengurangi kapasitas kerja. Wanita usia subur sangat rentan kekurangan zat besi dan menderita konsekuensi yang tragis seperti persalinan prematur, bayi dengan berat lahir rendah dan risiko kematian lebih besar (Fairweather-Tait, S dan R. F. Hurrell, 1996;Anonim, 2009;WHO, 2009) Seng (Zn) merupakan mikronutrisi kunci yang dibutuhkan untuk berbagai macam proses biokimia, fungsi imunologi dan klinis pada manusia. Sangat penting untuk mengaktifkan pertumbuhan dan perkembangan fisik dan neurologis pada bayi, anak-anak dan remaja.…”
