Zinc is better absorbed when taken with a meal that contains protein. Zinc is found in several foods, such as lean red meat, seafood (especially herring and oysters), peas, and beans. Zinc is also found in whole grains; however, large amounts of whole grains have been found to decrease the amount of zinc that is absorbed. Additional zinc can be added to the diet using treated (galvanized) kitchen utensils.
Food stored in uncoated cans can make less zinc available for absorption into food. Magnesium helps the body regulate its zinc levels, while zinc allows it to absorb magnesium more efficiently. Zinc will only hinder absorption when taken in abnormally high doses (around 142 mg of zinc per day). The amount of zinc you should take will help ensure that these two minerals can work together with each other.
A 3-ounce serving has 74 milligrams. That's five times more than you need per day. Eat them raw with lemon or bake them Rockefeller-style with spinach, onion, breadcrumbs and Parmesan cheese. Altogether, investigating these future perspectives with in vitro intestinal cellular models would not only improve current knowledge about the bioavailability and absorption of zinc in the intestines, as well as on the molecular regulatory parameters of its luminal absorption and its transport to the bloodstream, but would also contribute to the general understanding of zinc homeostasis in enterocytes, in addition to the results obtained so far.
In three-dimensional in vitro cellular intestinal models, the amount of metal in the apical and basolateral compartments, as well as the cellular zinc content, are analyzed to determine the amount of zinc absorbed and actually transported to the blood side (Figure 6A). On the contrary, the protein content of the foods consumed has a positive effect on the absorption of zinc due to the release of amino acids and peptides upon degradation. Making sure you have enough magnesium and getting all the zinc you need is vital to keeping your nutrient levels at their best. Possible regulatory mechanisms of zinc absorption in enterocytes during (A) excess zinc, (B) adequate supply and (C) zinc deficiency, based on experimental data on the zinc-dependent expression pattern of intestinal zinc transporters (ZnT) and IRT-like protein transporters (ZIP), as well as metallothioneins (MTs).
This highlights the importance of applying zinc corresponding to physiological concentrations in vivo in vivo in the intestinal lumen, particularly when analyzing transport and absorption kinetics, in order to avoid artifacts. In addition, the role of systemic and humoral factors in regulating the absorption of zinc from enterocytes in the intestinal lumen and its excretion through the basolateral exporter ZnT-1 in the blood should be thoroughly clarified. Regardless of the detailed experimental environment, almost all transport studies obtained with the Caco-2 models observe the absorption and transport kinetics of saturable apical zinc. Therefore, taking as much zinc as needed, as well as taking magnesium supplements, can help encourage mineral absorption.
In addition to zinc transporters in the apical and basolateral membranes of enterocytes, there is evidence that ZnT-2, ZnT-4, ZnT-6 and ZnT-7 also regulate the cytoplasmic concentration of zinc in enterocytes. As explained in detail in this review, the luminal and basolateral components, as well as the cellular composition of in vitro cellular intestinal models, are crucial for investigating zinc absorption and should represent the human intestinal epithelium in vivo and its surroundings as closely as possible. Some studies suggest that if you take zinc pills or syrup, but not supplements in pill form, within 24 hours of the onset of a cold, your symptoms won't be as severe or last as long. The detailed estimate of the zinc content of the fabrics and the references are shown in Supplementary Table S.1.Knowledge about the bioavailability of zinc from complex food matrices could be included in nutrition surveys.
Therefore, this section will focus on the application of in vitro cellular models in the investigation of intestinal absorption of zinc, will illustrate the aspects that must be considered when applying these models, and will highlight the advantages of in vitro intestinal cellular models compared to other in vitro or ex vivo methods. For this reason, your zinc levels are unlikely to be low enough to worry about, and you should get enough zinc through your diet. .
