The demand for calcium at different stages of life is different western media: these periods most need calcium supplementation.

Reference News Network reported on May 25 that Western media said that people at all stages of life daily calcium intake is not the same. Dr. Catherine Garcia of the Spanish Society of Endocrinology and Nutrition points out that in the first few years of life and adolescence, the demand for calcium is highest in a lifetime because of the rapid growth of long bones. Another stage of life where calcium demand is high is menopause, where calcium loss is more severe.
as for the best daily calcium intake, various agencies have given different recommendations, according to the website of Spain's Albesai newspaper on May 20. The European Food Safety Authority recommends 280 milligrams of calcium per day for infants between 7 months and 11 months of age, 450 milligrams per day for children between 1 and 3 years of age, 899 milligrams per day for children between 4 and 10 years of age, 1,150 milligrams per day for adolescents between 11 and 17 years of age, 1,000 milligrams per day for young people between 18 and 24 years of age and 950 milligrams per day for adults from the age of 25. Others argue that the daily intake of children over 4 years of age should be increased to 1,000 mg, and that it should be increased to 1,300 mg per day by puberty, especially when women are over 50 years of age.
, the most important sources of calcium in daily life are milk and dairy products, according to the Report. Milk contains 130 milligrams of calcium per milliliter. Garcia believes that drinking two glasses of milk a day, or 400ml to 500ml of milk, can provide 520mg to 650mg of calcium. Dairy products such as cheese are also rich in calcium. However, if you want to get the same amount of calcium from cheese and two cups of milk, you may need to eat 100 grams of cheese.
In addition to calcium-rich milk and dairy products, there are other foods that are also rich in calcium, including seafood (220 milligrams calcium per 100 grams), tonsils (240 milligrams per 100 grams of calcium), and olives (63 milligrams of calcium per 100 grams). In addition, vegetables such as beets, spinach and orchids also have higher calcium content.
it is worth noting that milk and dairy products contain higher bio-utilization of calcium than other foods. For example, 30% of the calcium in milk can be absorbed by the body, but spinach may be only 5%.
to increase calcium absorption, you also need to take enough vitamin D. The easiest way to get vitamin D is to get in the sun. Eating more fatty fish, such as sardines and salmon, can do the same. In addition, egg yolks are also rich in vitamin D.
