TL;DR: It is concluded that the increased dietary fiber levels in the MMs increased the mineral levels, and MMs with intermediate and high fiber levels may be used to improve the mineral balance of poor diets.

TL;DR: In this article, a mineral absorption promoter consisting of sialyllactose or its acid addition salt as an active ingredient is presented, which can be taken as a food and beverage and medicine so that symptoms such as osteoporosis, iron deficiency, etc. can be improved.
Abstract: PURPOSE: To obtain a mineral absorption promoter comprising sialyllactose or its acid addition salt as an active ingredient. CONSTITUTION: This mineral absorption promoter comprises sialyllactose shown by the general formula Neu5Ac α 2-3Galβ1-4Glc, Neu5Ac a 2-6Galβ1 4Glc, etc., or its acid addition salt as an active ingredient. The mineral absorption promoter is taken as a food and beverage and a medicine so that symptoms such as osteoporosis, iron deficiency, etc., can be improved. The mineral absorption promoter can be mixed in a feed for domestic animals.

TL;DR: In this article, enriched stable isotopes were used in nutrition studies of normal, healthy adults to measure zinc, copper, and iron absorption, and the effects of age, pregnancy, and deveral dietary variables were studied.
Abstract: Enriched stable isotopes were used in nutrition studies of normal, healthy adults to measure zinc, copper, and iron absorption. After obtaining baseline values for zinc, copper, and iron absorption from diets adequate in all nutrients, the effects of age, pregnancy, and deveral dietary variables were studied. Stable isotopes of zinc, copper, and iron were incorporated into diets. Complete fecal samples were collected and the unabsorbed isotopes remaining in the samples were measured by thermal ionization mass spectrometry, the most precise analytical method for the determination of stable mineral isotopes. Stable isotopes were also infused in five young men to evaluate the potential of studying mineral utilization and kinetics with stable isotopes. The results of these studies demonstrate that a number of factors can affect mineral absorption, but the specific effects differ for different minerals. Isotopic enrichments could be measured in urine and blood, so kinetic studies of utilization of essential minerals are now feasible with enriched stable isotopes. Continued use of stable isotopes to determine mineral absorption, combined with stable-isotope studies of mineral utilization, balance data, and biochemical indicators of mineral status, should result in a better understanding of mineral requirements and metabolism under a variety of conditions.

TL;DR: The results suggest that the usual consumption of white tea is safe, although its effect on long-term iron absorption at high doses warrants more detailed investigation.
Abstract: We investigated the antinutritional effect of white tea extract (0, 15, and 45 mg of the tea solid extract per kilogram body weight) incorporated in the drinking water of rats for 3 and 30 days. Gender-based differences were found for all these variables, except apparent protein digestibility and the apparent absorption of calcium, phosphorus, and iron. White tea extract consumption did not significantly change body weight gain, food intake, food efficiency, protein efficiency ratio, apparent protein digestibility, nitrogen balance, or the apparent absorption of calcium, phosphorus, magnesium, and zinc. Nevertheless, the apparent absorption of iron was slightly (15–18%) but significantly (P < 0.05) lower in rats that consumed white tea at the highest dose compared with the control groups at both 3 and 30 days. Our results suggest that the usual consumption of white tea is safe, although its effect on long-term iron absorption at high doses warrants more detailed investigation.
