In this invention, the room temperature impact energy of the material is not greatly changed with the intercritical heat treatment at 660Â° C. to 670Â° C. However, the impact energy of the material is significantly increased by the intercritical heat treatment at 680Â° C. to 750Â° C. for 1 hour to 8 hours.
Magnesium is widely distributed in plant and animal foods and in beverages. Green leafy vegetables, such as spinach, legumes, nuts, seeds, and whole grains, are good sources [ 1, 3 ]. In general, foods containing dietary fiber provide magnesium.Magnesium is also added to some breakfast cereals and other fortified foods. Some types of food processing, such as refining grains in ways that remove the nutrient-rich germ and bran, lower magnesium content substantially [ 1 ].Selected food sources of magnesium are listed in Table 2.n general, foods containing dietary fiber provide magnesium. Magnesium is also added to some breakfast cereals and other fortified foods. Some types of food processing, such as refining grains in ways that remove the nutrient-rich germ and bran, lower magnesium content substantially [ 1 ].
An easy way to remember foods that are good magnesium sources is to think fiber. Foods that are high in fiber are generally high in magnesium. Dietary sources of magnesium include legumes, whole grains, vegetables (especially broccoli, squash, and green leafy vegetables), seeds, and nuts (especially almonds).Other sources include dairy products, meats, chocolate, and coffee. Water with a high mineral content, or âhardâ water, is also a source of magnesium.esearchers estimate that the average personâs body contains about 25 grams of magnesium, and about half of that is in the bones. Magnesium is important in more than 300 chemical reactions that keep the body working properly.
