Calcium Deficiency Causes: Calcium in Foods and Calcium Supplementation

Updated on July 31, 2012

Calcium deficiency is a major concern in the United States. Over 75% of Americans don't get what they need. Calcium does ninety percent of its work building bone mass during the first seventeen years of life with the balance occurring by age twenty eight. If bone loss occurs after this time it cannot be be restored. Calcium is important for healthy bones throughout life. It is an essential element vital to many body functions.

The two causes of calcium deficiency are a diet low in calcium and an inability to absorb and metabolize the mineral. Calcium is the main component of bones and teeth and is involved in maintainance, growth and reproduction of the human body. Other functions are transmitting nerve impulses, regulating heartbeat, blood coagulation, muscle contraction and relaxation, stimulating hormone secretion and the activation of enzyme reactions. Calcium deficiency is linked to osteoporosis, colon cancer and high blood pressure.

A low calcium level in the blood because of poor diet causes the body to leach calcium from the bones. The body returns calcium to the bones when it receives it through diet. If the diet continues to be poor in calcium there will not be enough calcium in the blood to give back to the bones. Eventually this leads to osteoporosis.

Among the youth of America there is widespread calcium deficiency putting them at risk for many major health problems. Infants have been developing rickets, a disease usually associated with vitamin D deficiency, around the age of twenty months. This is due to lack of calcium in the diet after breast feeding was discontinued. According to the National Institutes of Health, only about 25% of boys and 10% of girls get enough calcium in their diets. Osteoporosis in Americans aged 50 years old and up is the reason for 1.5 millon fractures every year. It is estimated that 10 million people have osteoporosis and 34 million more have low bone mass placing them at risk for osteoporosis.

High blood pressure affects around 50 million Americans and is very common among African Americans and older people. A study done on women with a diet continually low in calcium revealed that women who take 1500-2000 mg of calcium daily reduce the risk of getting high blood pressure from pregnancy by as much as 50%. It was also found that pregnant women who had a calcium rich diet, had babies that weighed more and had lower blood pressure that continued at least through the first five years of life.

Calcium may be Beneficial in Prevention and Treatment of Several Health Conditions which include cataracts, osteoporosis, colon cancer, high blood pressure, kidney stones, premenstrual syndrome, pregnacy induced high blood pressure and inflammatory bowel disease.

The best sources of calcium are spinach, collard greens, mustard seeds and turnip greens. Other great sources include kale, swiss chard, blackstrap molasses, mozzarella cheese swiss chard, basil. cinnamon, thyme, dill seed, and peppermint leaves. Good sources include, broccoli, romaine lettuce, celery, brussel sprouts, oranges, asparagus, sesame seeds, fennel, cabbage, summer squash, basil, thyme, dill seed, cinnamon, and peppermint leaves, cow's milk, and goat's milk. (The amount of calcium in food is not affected by cooking or storage).

Calcium supplementation is necessary for those who do not adequate amounts of calcium from their diet. Calcium Supplements can be purchases in different forms. The most common are carbonates or citrates. Calcium citrate is the best choice for maximum absorption and bioavailability in the body.The recommended daily intake of calcium is as follows: 210mg for 0 to 6 months old, 270mg for 6 to 12 months old, 500mg for1 to 3 years old, 800mg for 4 to 8 years old, 1300mg for 9 to 18 years old, 1000mg for 19 to 50 years old and 1200mg for 51 years old and above.

Calcium is one of the essential minerals needed to maintain life. Most people in America today are calcium deficient and are in danger of serious health conditions developing. By taking preventative measure today you can avoid the undesirable and inevidable outcome of calcium deficiency.

      Thanks for your comment KimmiS. You are right about the cow's milk. I learned the truth about it after I wrote this article and have not updated it. Thanks for the reminder.

      Jagat you are actually incorrect.

      Vegetarians have a much lower risk of bone disease (if they eat plenty of fruits and vegetables).

      SteveMark It is an informative article but you are incorrect about milk being a source of calcium. Cow's milk has the opposite effect, it depletes our calcium.

      This is why milk drinking nations like America have the highest rates of bone disease.

      Calcium is highly important for the growth of our bones. Back when I had a DePuy Pinnacle hip implant, I had to eat green-leafy veggies and at least 1-2 glasses of milk each day.

      Lately though, there have been reports of lawsuits from people who have a similar Pinnacle device. I hope everyone who have had the implant will be fine.

      Thank you for the great information on calcium and vit. D. I used to be very low in both, but with supplements and brought my levels up considerably.

      I completely agree that calcium is necessary for healthy growth and development, but I don't believe dairy is needed to obtain that calcium. Americans consume the highest amounts of dairy and have some of the highest rates of osteoporosis. Dairy products obviously are not the answer! Dairy along with many other common American staples, such as processed foods and meat are acid forming and pulls minerals from your bone to balance ph levels. I would suggest the other foods listed for calcium and save your self from the many other problems associated with dairy. Other then the disagreement on dairy products, great article Steve!

      Thank you so much. That could have been writen for me. I suffer from hereditary bone disease and I'm always intersted in more ways to absorb calcium.

      This article was very helpful. I appreciate you work.

      Dear Steve:

      I have experience many aliments regarding a magnesium deficiency in life. At first, I thought of was a calcium deficiency. Some of the ailments that I have encountered were the following: muscle cramping, my hand and legs going numb,ringing in the ears, insomnia, low blood sugar, confusion, lack of concentration, nervousness, anxiousness, pains in my knee joints, fatigued,craving for salt food, receding gums, and bleeding gums. Then once I started to take magnesium supplements in powered formed and transdermal topical mgcl, then all my problems went away.

      Indeed magnesium is a very important mineral, that is needed in order for calcium to do its job. If low levels of magnesium are in the system, then calcium is going to do a lot of harm to the bodily functions, such as osteoporosis, arthritis, kidney stones, hardening of the arteries, heart problems, etc.

      If you have any questions regarding this, you can reach me at calexpress@yahoo.com

      Sincerely,

      Joe

      I agree that calcium and Vit D deficiency is epidemic in our country. Kids are raised on Kool-Aid instead of milk. Personally, I think nothing besides milk and water should be available in schools. Even healthy juice is super high in calories and provides no calcium. But, it's never too late to make a change. Thanks for the heads up about how very vital calcium is!!

      Thanks for this information!! Very thorough. My grandmother and mother both suffered terribly with osteoporosis, as it's kind of a given when you deal with Celiac Disease. Calcium magnesium is good in liquid form if you deal with malabsorbtion problems. So its good to start with the calcium supplements when young. Peace ~ Kim

      I never knew how much Calcium did until I had my parathyroid removed. Now I have to constantly watch it and have periodically had to get an IV of calcium. Thank you for letting others know about it.

      Thanks this page has really helped me, I have recently had to undergo numerous blood tests as my calcium levels are very low......only trying to get answers from the doctor is like trying to get blood from a stone! I was diagnosed with inflammatory bowel disease......but then cleared???? I have had a number of low level blood tests for various substances and have been arguing about malabsorbtion for some time? Now at least I feel better armed when I visit the doctor for my results.........thank you.

      Thanks for your comments everyone. A diet rich in calcium involves eating lots of foods high in calcium. It is really important to make sure you are getting the recommended daily intake for your age group.

      I know that milk contains calcium, but I have read and heard that milk creates mucus. The Chinese on the whole, especially older generations do not really consume as much milk as the Caucasians. The modern Chinese do consume milk. They depend more on soy. I drink more soy now.

      Steve, may I add from what I read our diets in USA is acidic and the body has to maintain a 7.1 PH balance. Calcium is a alkaline, the bone is biggest source so if your not ingesting any alkalines from the outside the body must find alkaline from within, the Bone. Good article.

      Considering the statistics of osteoporosis, its safe to assume that many people neglect the importance of calcium. People must be educated in its importance early in life. Thanks for this informative hub!

      Thanks for your comment Ronald. The age breakdown is actually 19 to 30 and 31 to 50. I put

      19 to 50 because the 1000mg intake is the same for both groups.

      Thanks for your comment Lynn. Weight training will definitely improve bone mass but it is important to make sure you are getting your daily requirement for key nutrients as well. I have written a hub called How to Prevent Mass Reduction and Fragility in Aging Bones which discusses all these nutrients.

      Steve,

      I've read about bone density improvement with weight training. How much do you think that some resistance training would help?

      I just found your hubs and you certainly give a lot of information. Thanks.

      Mulder I've used both bee pollen and goji berries. Excellent nutritional sources. By the way, I did see your request for me to write a hub on bee pollen. It is one of several requests I have received and I'm just trying to find the time to fit everything in.

      I have osteoporosis and I believe it's because I was always on the latest fad diet when I was younger. Osteoporosis is hereditary so people should be aware that family members should have a DEXA scan. Great hub.
