Calcium in Your Diet

Why Calcium in Your Diet


For optimal bone health, to reach peak bone density, and to protect bone as we age, vitamin D and calcium are necessary minerals. In later life, a lack of these nutrients can cause diseases with short or lengthy latency, such as rickets, osteomalacia, and osteoporosis. Information on the popularity of these minerals in India is scarce. The consumption of milk, milk products, and grains has significantly decreased over the past 50 years despite an increase in the RDA/RDI for modern India. This is caused by a change in lifestyle, insufficient milk consumption among different socioeconomic groups, and a switch from cereal to rice and wheat in food intake.


Studies by Chapuy and Dawson-Hughes show that older people who took calcium and vitamin D supplements were 35–55 percent less likely to suffer non-vertebral fractures and age-related bone loss. Vitamin D and calcium are essential components of the medication used to treat post-menopausal osteoporosis and age-related bone loss.



Why Calcium Intake is Important?


Calcium’s function in the body  Calcium is involved in:


  • Strengthening the teeth and bones
  • Controlling the contraction and relaxation of muscles
  • Controlling cardiac function
  • Ensuring proper blood clotting
  • Messages travelling through the nerve system
  • Enzyme activity


A deficiency in calcium may cause rickets in children and osteomalacia or osteoporosis in adults.




Calcium levels in the blood are closely regulated. If the diet does not contain enough calcium, the bones will release it into the blood, but generally no symptoms appear. Hypocalcemia, a more severe calcium deficit, is brought on by conditions including kidney failure, digestive tract operations like gastric bypass, or drugs like diuretics that prevent absorption.


Hypocalcemia signs and symptoms:


  • Muscle Weakness Or Cramps
  • Tingling Or Numbness In The Fingertips
  • Unusual Heartbeat
  • Lack Of Appetite

People who consistently consume insufficient calcium from their diets or who see a decline in their ability to absorb calcium may develop a gradual, progressive calcium shortage. Osteopenia is the first early stage of bone loss, and if left untreated, osteoporosis develops. People at risk include, for example:

Postmenopausal women—Menopause reduces the body’s levels of oestrogen, a hormone that promotes calcium absorption and bone mineral retention. In order to prevent osteoporosis, doctors occasionally recommend oestrogen and progesterone-based hormone replacement treatment (HRT).

Amenorrhea is a condition where menstruation stops early or is disturbed. It is frequently observed in young women with anorexia nervosa or athletes who engage in intense physical training.


Lactose intolerance or milk allergy: Occurs when the body is unable to digest milk’s casein, whey, or lactose sugar. Intolerant to lactose can be inherited or acquired (not consuming lactose in the long-term may decrease the efficiency of lactase enzyme)
