Importance of Calcium – Deficiency, Cause And Calcium Rich Food Diet

Calcium is perhaps the most essential nutrient when it comes to bone health. Building strong bones is like building a healthy balance in your “calcium bank account.” Bones are living tissue and constantly in a state of turnover, making calcium deposits and withdrawals daily.

Bones don’t come with a lifetime guarantee. They need continuous maintenance or they can weaken and break. If your diet is low in calcium, your body will take calcium from your bones to keep blood calcium at normal levels.

What Is Calcium Deficiency?

Do you think drinking a glass of milk is enough to get your daily dose of calcium? But in reality, it is not.

Calcium deficiency is slowly becoming a pandemic due to poor nutritional choices. Find out whether you too are suffering from it.Although calcium plays a key role in the maintenance of strong and healthy bones, it also helps in blood clotting, early developmental growth and muscle contraction and relaxation. This mineral can be easily obtained from natural food sources like leafy vegetables, yogurt, nuts and cheese. But most people (particularly in the age group of 14-20 years) suffer from calcium deficiency due to lack of efficient absorption.

Here are some signs and symptoms of calcium deficiency you need to be aware of.

1# Weak Bones

Inadequate calcium in your body may affect the health of the bones. This mineral is vital for you to build your bones and keep them strong.With a low calcium level, your bones are likely to get weak, which will increase susceptibility to osteoporosis or fractures. In a long time, weak bones may also impact the stature and overall strength of a person.

This is why parents have to ensure that their children are consuming calcium-rich foods, particularly during their growing years.If you do not take in enough calcium, your body begins using the calcium from the bones to ensure a normal cell function.Old people, particularly women after menopause, should take calcium supplements to prevent fractures and bone loss that occur with age.

2# Muscle cramps

Despite an adequate level of hemoglobin and sufficient water intake, if you suffer from recurring muscle cramps, you could have low calcium levels. Muscle cramps followed by muscle aches, especially in the thighs and calf muscles, is an early indication of low calcium levels.

3# Lowered bone density

Calcium is required for mineralisation of bones to keep them strong as you grow old. Therefore, low calcium levels directly affect the bone density and increases susceptibility to osteoporosis and fractures.

4# Brittle nails

Like your bones, your nails also need calcium deposits for maintaining their integrity. Lack of adequate levels of calcium could make your nails extremely weak and susceptible to breaks.

5# Toothache

Around 99% calcium present in your body is stored in your bones and teeth. Naturally, if your calcium levels drop, you ll be susceptible to toothache and decay. Also, you ll be at a greater risk of suffering from periodontal disease. In children, calcium deficiency has been linked to delayed and defective teething.

6# Premenstrual cramps

Women suffering from calcium deficiency have to go through a lot of pain during their menstruation. The exact mechanism by which calcium could be relieving menstrual pain is not yet clear but its role in muscle contraction and relaxation seem to be crucial. Apart from pre-menstrual cramps, calcium deficiency is also linked to irregular menstruation and excessive bleeding in women. Calcium is also involved in normal development of the uterus and ovarian hormones in women.

7# Frequent illness

Calcium seems to play an important role in maintaining a healthy immune system as well. It has been observed that those deficient in calcium are more likely to acquire common respiratory and intestinal infections. Deficiency of calcium reduces body’s resistance against pathogen attack.

8# Fatigue

Bone and muscle aches generally causes weakness in calcium deficient people. But low calcium levels are also linked to insomnia, fear and mental derangements that increase stress and fatigue. You may look pale and feel tired or lazy all the time. Fatigue is also a common symptom in women who develop calcium deficiency after childbirth. They are more likely to suffer from lack of breast milk, poor concentration and extreme tiredness. Therefore, it is advisable that pregnant women should get a regular supply of 1000-1200 mg calcium every day.

9# Difficulty Losing Weight

Sufficient calcium intake is very important for a healthy body weight. It has been discovered that most obese people don’t consume the required daily need of calcium. Therefore, if you’re struggling to reduce weight, it can be due to deficiency of calcium.

According to a study, dietary calcium plays an important role in regulating the energy metabolism that can accelerate weight loss whereas diets low in calcium attenuate weight as well as fat gain.According to a later study , boosting calcium consumption will spur weight loss, but only in those whose diets lack calcium.

10#Constant Sleep Problems

Turning and tossing in bed during the night may have a direct effect on your mood as well as work productivity. Deficiency of sleep on the regular basis is also one of the warning signs and symptoms of calcium deficiency in humans.

Calcium helps to produce melatonin, a sleep hormone that aids in maintaining the sleep-wake cycle of your body. Moreover, this sleep hormone can also increase naturally during the night in order to help you to sleep soundly.

Whenever there is the lack of calcium in your body, melatonin production gets hampered. In addition, calcium also acts as a natural relaxant.

Therefore, if you’re having problems staying asleep or falling asleep, you should check your calcium level before reaching for sleep aids. Even drinking 1 cup of warm milk before going to bed may also promote sleep.

What Causes Calcium Deficiency?

We know calcium is a vital mineral for building strong bones and teeth and to help stabilize blood pressure, but did you know it has a major role in how our inner body functions? Calcium is needed for the release of hormones and enzymes, blood coagulation, regulating muscle contractions, transmission of nerve signals, and moving blood through our blood vessels.

Calcium deficiency occurs when your body is not receiving enough minerals such as calcium and goes through a process called demineralization. Without this vital alkaline mineral, your body relies on the existing calcium in your bones, teeth, and organs, which leads to calcium deficiency.

As we age, our bone density decreases naturally; and since most of our calcium is stored in our bones, our daily requirement for calcium increases. Other factors in losing calcium levels in our blood system include:

  • High sodium and phosphorus intake
  • Deficiencies in vitamin D and magnesium

Health conditions can also play a part in low calcium absorption or loss. This can include chronic kidney disease, thyroid issues, gastric bypass surgery, and even certain prescription drugs such as anti-seizure medications, proton pump inhibitors, and chemotherapy drugs.

The amount of calcium you need every day depends on your age and gender:

# Women’s

Younger To Age 50 -1,000 mg* daily.

Age 51 To Older- 1,200 mg* daily

# Men

Younger To Age 70-1,000 mg* daily

Age 71 To Older-1,200 mg* daily

This includes the total amount of calcium you get from various foods and supplements.

Calcium Rich Foods To Include In Your Diet

Each day we lose some amount of calcium through our nails, skinhair, sweat, urine and faeces. Our bodies cannot produce new calcium and this requirement is fulfilled by extracting calcium from our bones. This adversely affects bone density causing the bones to become soft and weak. This increases the risk of fractures and osteoporosis. Deficiency of calcium can lead to health issues like muscle cramps, loss of appetite, lethargy, convulsions, numbness in fingers and toes and abnormal heart rhythms. Thus, the best way to fulfill this deficiency is to increase the intake of foods that are rich in calcium.

1# Low Fat Cheese

Among the dairy products, cheese is a good source of calcium. Moreover, unlike other dairy products, it has low lactose content and is suitable for those who are intolerant to lactose. It enables re-mineralization i.e. deposition of calcium and phosphorus in teeth, thus strengthening tooth enamel. Mozzarella Non fat cheese has the highest concentration of calcium with 1 cup shredded cheese providing 1086 mg or 109% DV of this mineral. Other varieties that are good sources of calcium include low fat Swiss (27% DV), reduced fat Parmesan (31% DV) and cottage cheese 2% fat (2%).

2# Low Fat Milk & Yogurt

Milk is considered as one of the best sources of calcium. A cup serving of low fat milk contains 306 mg or 31% DV of calcium. Low fat yogurt is another dairy product that can be a good alternative to milk. Besides, the culturing process involved in the preparation of yogurt makes it easy on your digestive system. An 8 ounce serving of yogurt provides 225 grams of calcium which is more than the same amount of milk provides. Plain yogurt also contains 10 to 14 grams of protein which is equivalent to 20% of the daily protein requirement. You can use yogurt in salads, soups and desserts to improve the nutritive value and taste of the food.
