Calcium-Rich Foods: Importance & Sources of Calcium Foods for Health

Importance of Calcium-rich Foods

Calcium is the most abundant mineral in the human body, with approximately 99% of it stored in the teeth and bones. It plays a crucial role in the growth and maintenance of the body. At birth, the amount of calcium in the bones is around 25 grams, which increases to about 1200 grams till adulthood. The remaining 1% of calcium is found in the muscle, cell fluids, and blood where it is essential for muscle and heart contractions, blood clotting, hormone and enzyme secretion, and nervous system function.

Both plant and animal foods contain calcium. Dairy products such as yoghurt, cheese, and milk along with fishes like sardines and salmon are some rich sources of calcium among animal foods. Green leafy vegetables like fenugreek leaves, broccoli, and amaranth as well as cereals such as ragi and seeds (e.g., sesame seeds), and nuts (e.g., pistachios and almonds) are a few good sources of calcium among plant-based foods.

Milk is considered one of the best calcium foods, including mother’s milk for infants. It is accompanied by an appropriate proportion of phosphorus, which aids in its utilisation in the body. Milk products like curd, paneer, and mava also provide decent amounts of calcium. Millet ragi and sesame seeds are high in calcium. While green leafy vegetables are good sources of calcium, only a portion of the calcium they contain is readily absorbed by the body. Fresh and dried fish can provide significant amounts of dietary calcium.

The Indian Council of Medical Research (ICMR) recommends a daily intake of 600–800 mg of calcium for adults, which increases to 1200 mg for lactating and pregnant mothers. Insufficient calcium consumption over a prolonged period is associated with conditions like osteopenia and osteoporosis.

Effects of Calcium Deficiency on Bone Health

The insufficient consumption of dietary calcium may not result in immediate noticeable symptoms. The body tightly regulates the levels of calcium in the bloodstream. However, in the long term, inadequate calcium intake can lead to osteopenia, a condition characterised by decreased bone density, which, if left untreated, can progress to osteoporosis.

Insufficient calcium intake also increases the risk of bone fractures, particularly among older individuals. The absorption of calcium from the gastrointestinal tract is influenced by various factors. Optimal absorption occurs when calcium intake is low while the body’s demand is high. Factors such as an acidic environment, vitamin D levels, age, dietary fibre intake, and estrogen levels also affect calcium absorption.
