Sources Of Calcium

calcuim food that contain calcium

Dairy products (milk, yogurt, cottage cheese, cheese) are the main sources of calcium. Individuals with lactose intolerance (people who cannot completely digest the milk sugar lactose) and those who are vegans tend to avoid or eliminate dairy products from their diet. We all know that it is important for vegetarians to meet calcium needs with alternative calcium sources.

Good vegan sources of calcium include tofu (if prepared from calcium sulphate), green leafy vegetables, dried figs, broccoli, seeds and nuts. Some soya milks, instant breakfast cereals are also fortified with calcium. Drinking water can provide as much as 200 mg of calcium daily, as hard water contains a rich source of calcium.

Although most grains are not high in calcium, they do contribute calcium to the diet because they are consumed regularly and frequently.

What Affects Calcium Absorption And Excretion From The Body?

Only 20-30% of calcium in the average diet is absorbed into the body, the rest gets excreted.

A high protein diet, especially based on animal foods, causes calcium loss in the body. The higher sulphur-to-calcium ratio of meat increases calcium excretion.

Calcium absorption can also be affected by the amount of calcium present in the body, amount of vitamin D presence (helps improve calcium absorption), age, pregnancy (intestinal calcium absorption increases during pregnancy), fibre content in diet etc. The amount of calcium consumed at one time such as in a meal is inversely related to the absorption rate.

Calcium excretion refers to the amount of calcium eliminated from the body through urine, feces and sweat. Calcium excretion is affected by factors such as amount of sodium, protein, caffeine and potassium in diet.

Calcium is lost in cooking some foods even under the best conditions. To retain calcium:

- Foods are best cooked in a minimal amout of water.

- Cook food for the shortest possible time.

What Does Calcium Defiency Lead To?

Osteoporosis: major cause of bone fractures in the elderly, especially women. Prevention includes an adequate intake of calcium throughout life, but especially in childhood and young adulthood; and reduce trigger factors such as smoking, heavy drinking and lack of physical exercise. Diets high in protein and salt also increase calcium loss from the body. Post-menopausal women are more prone because they produce less estrogen, which protects the skeleton in younger women..

Rickets is a childhood disorder involving softening and weaking of the bones. It is caused by lack of vitamin D, calcium, or phosphate. Deficiency of vitamin D leads to improper regulation of calcium and phosphate. Symptoms of rickets in children included delayed sitting, crawling, walking and the development of bowlegs.
