The Importance of Calcium: Understanding the Risks and Benefits

Calcium is a vital mineral that plays a crucial role in maintaining strong bones and teeth, as well as supporting various bodily functions. From regulating heart rhythm to facilitating muscle function, calcium is essential for overall health.

Recommended Daily Allowance (RDA) for Calcium

The Institute of Medicine recommends the following daily calcium intake:

– 1,000 mg/day for adults aged 19-50 years
– 1,300 mg/day for adolescents aged 9-18 years
– Lower amounts for younger age groups and higher amounts for senior citizens

Food Sources of Calcium

Incorporate these calcium-rich foods into your diet:

– Dairy products (milk, cheese, yogurt)
– Dark green leafy vegetables (spinach, kale, broccoli)
– Fish with edible bones (sardines, salmon)
– Calcium-fortified foods (soymilk, fruit juices, milk substitutes)

Role of Calcium in the Body

Calcium plays a vital role in:

– Blood clotting
– Muscle tone and movement
– Hormone and enzyme release

Certain individuals are more susceptible to calcium deficiency:

– Post-menopausal women
