Calcium. An essential nutrient in human health.
WHAT EXACTLY IS CALCIUM?
Calcium is a soft, alkaline earth metal. It is one of the most abundant metals in the human body.
While there are a number of excellent sources of calcium, the main one that comes to mind is DAIRY food. Here, I will list all the other AMAZING foods that are rich in this wonderful nutrient and it’s benefits.
WHAT ARE THE BENEFITS OF CALCIUM?
An excess of calcium in the body can lead to kidney stones, constipation, prostate cancer, accumulation in blood vessels and reduce the absorption of zinc and iron.
Calcium does not work alone. It requires others nutrients for absorption and metabolism including phosphorus, vitamin D and protein. If calcium levels in the body reduce, even slightly, it is drawn from other sources to assist in maintaining blood levels and prevent hypocalcemia (this happens within minutes of a decrease in serum calcium).
Absorption of calcium occurs in the gastrointestinal tract (GIT), not in the stomach, and requires a pH of 6.5-7.5.
‘At risk’ groups for calcium deficiency are mainly women, however, adolescents, the elderly and men are also at risk. For women, post-menopause, physical hyperactivity, and those with eating disorders are at greater risk.
Deficiency may be caused by dietary habits, medications, gastrointestinal disorders, chronic disease, and genetic defects. A deficiency in calcium can lead to Rickett’s, blood clotting issues and osteoporosis, heart contraction problems, renal dysfunction, mood issues and hormone disorders.
The parathyroid glands house most of the body’s calcium receptors.
Consuming protein-rich foods with calcium help to reduce the risk of deficiency, and support bone and muscle growth and maintenance.
Calcium intake should come mainly from whole foods, rather than a single calcium supplement, as synergistic nutrients are found in whole food. While supplementing may be required for a number of reasons, it should contain a whole matrix of nutrients that work together with calcium for the best results.

As you can see, there are PLENTY of other sources of calcium besides MILK, which is a commonly referred to ‘food’ to increase your calcium intake. A great way to ensure you get enough calcium is to choose a combination of fresh foods daily. Assuming all absorption channels in the body are in good ‘working’ order, supplementation may not be required.
Some figures for calcium requirements are outlined below.
