Calcium is a chemical element which is essential for living organisms, including humans.
Calcium's chemical symbol is "Ca". It is found in many foods. We need to consume a certain amount of calcium to build and maintain strong bones and healthy communication between the brain and various parts of the body.
Calcium continues strengthening the bones of humans until they reach the age of 20-25 years, or when they reach their peak mass. After that age, the element helps bone maintenance as well as slowing down bone density loss, which is a natural part of the aging process. People whose calcium intake is inadequate before the age of 20-25, have a considerably higher risk later on in life of developing brittle bone disease or osteoporosis, because calcium is drawn from the bones as a reserve.
Calcium regulates muscle contraction, including the heartbeat. It also plays a key role in normal blood coagulation (clotting).
Nearly all of the calcium in our bodies is stored in our teeth and bones, where it supports their hardness and structure.
Calcium also plays a role in the release of hormones and enzymes, as well as helping blood vessels move blood around the body. A 2010 study carried out in North Carolina State University found that adequate calcium early in life may protect against obesity later on
Vitamin D helps the body absorb and retain calcium in the bones.
Calcium rich diets increases women’s lifespan- women whose diets are rich in calcium probably live longer than their counterparts whose diets are low in calcium, researchers from McGill University in Canada reported in the Journal of Clinical Endocrinology and Metabolism.
Rich sources of calcium includes:Milk,Cheese(be discret in consumption)Yoghurt ,Seaweeds, such as kelp, hijiki and wakame,Nuts and seeds, including pistachio, sesame, almonds, hazelnuts,Beans,Figs,Broccoli,Spinach,Tofu,Dandelion leaves,any fortified breakfast cereals(be discret in consumption,Crushed eggshells - they can be ground into a powder and added to foods and/or drinks Some dark-green vegetables may contain high levels of oxalic acid which reduces the body's ability to absorb calcium.
According to the American Institute of Medicine (IoM), calcium should be consumed daily at the following amounts:
Age 0 to 6 months: 200 mg per day
Age 7 to 12 months: 260 mg per day
Age 1 to 3 years: 700 mg per day
Age 4 to 8 years: 1000 mg per day
Age 9 to 18 years: 1300 mg per day
Age 19 to 50 years: 1000 mg per day
Breastfeeding or pregnant teenager: 1000 mg per day
Breastfeeding or pregnant adult: 1000 mg per day
Age 51 to 70 years (male): 1000 mg per day
Age 51 to 70 years (female): 1200 mg per day
Age 71+ years: 1200 mg per day
