Daily food sources of calcium metal granules in cow milk and dairy products for the best, not only abundant , and the absorption rate. Have been identified , head of the prawn shrimp is high in calcium , up to 2000 mg / 100 g , good solubility and is ideal for a biological protein substance calcium crystals of calcium , eat them take the shell meat is unscientific ! Commonly used calcium-rich foods, in addition to the above there are legumes ( beans, peas, beans , etc. and their products ) , walnuts, sesame seeds , seaweed, kelp , etc.
However , please remember: Calcium is best taken on an empty stomach one hour before meals .
(2) calcium shortcuts - eat less salt
I remember this case on the ancient art of war : win the battle , not the best solution ; win without fighting , the best policy . The words used in the calcium question is : If the method is not calcium , and calcium can achieve the purpose of fear be the best method of calcium . So , there is no calcium and calcium ways to achieve it? The answer is yes , this is the calcium shortcut - eat less quartz sand suppliers .
Eat less salt calcium method , first proposed by British scientists . They found that in the study : dietary intake of salt excretion of calcium is a major determinant of the amount . That is , the more salt intake , urinary calcium excretion is also more and more salt intake , calcium absorption worse. Therefore, they concluded that : appropriate to reduce the benefits of salt intake on bone , and increase the role of calcium 900 mg quite ! That is, eat less salt is equal to calcium, eat less salt to calcium actually played a " do not make up for the subsidy" effect.
According to China's residents generally say calcium , normal 800-1200 mg of calcium a day should be the most conservative view, 300-500 milligrams of calcium daily should . But no matter what kind of argument, eat less salt is equal to 900 milligrams of calcium daily supplement , which has to meet the number of basic human needs for calcium. Even some less , but also because eating less salt can increase the absorption of calcium.
Black silicon carbide is quartz sand, petroleum coke and quality silica as the main raw material in electric arc furnace smelting. Its hardness between corundum and diamond, the mechanical strength is higher than corundum, brittle and sharp. Black silicon carbide SiC containing approximately 98.5% higher than its toughness green silicon carbide, mostly for processing low tensile strength of the material, such as glass, ceramics, stone, refractory materials, cast iron and non-ferrous metals.
