What is Calcium and Why is it Important?

What is Calcium?

Calcium is a mineral found in nature in different foods and supplements. It is one of the most plentiful minerals in the body, responsible for numerous biological processes and bone health, including muscle contraction and nerve function. Almost 99% of calcium in the human body is stored in bones and teeth, making them strong and resistant to fractures or bone loss.

Why is Calcium Important?

Calcium is necessary for the normal functioning of the body. It plays a crucial role in maintaining strong bones and teeth and is essential for muscle and nerve function. Furthermore, it regulates blood pressure and is vital for blood clotting and maintaining a healthy heart rhythm.

How Much Calcium Do You Need?

As per the recommended dietary allowances (RDA), the daily calcium intake for an adult individual (both men and women) is 1000 mg. However, women over 50 years and men older than 70 years require 1200 mg of calcium per day. Children and adolescents also have varying requirements, from 200-1300 mg, depending upon their age and developmental stage. Make sure to consult a healthcare expert for the ideal calcium intake for you.

What Are the Best Sources of Calcium?

Dairy Products

Dairy products are the best sources of calcium. Yogurt, cheese, and milk are excellent choices that provide a high amount of calcium per serving. One cup of milk contains around 300mg of calcium, and a single serving of yogurt (150g) contains approximately, on average, 250 mg to 400mg of calcium. Low-fat milk and yogurt variants are also great options for people looking to maintain a lower calorie or fat-controlled diet.

Tofu

Tofu is an excellent plant-based source of calcium and a suitable option for vegans and those who are dairy intolerant. Half a cup of tofu provides about 434mg calcium, which equivalent to approximately 43% of the daily value (DV) for calcium.

Leafy Greens

Leafy greens are rich in calcium and in good supply in many diets, and they come packed with other essential nutrients as well. Spinach, kale, dandelion greens, Bok Choy, Fenugreek leaves, and mustard greens are great sources of calcium. In particular, cooked spinach is an excellent source of calcium and provides approximately 260mg of calcium per cooked cup. However, leafy greens, particularly spinach, also contain oxalate, which can interfere with calcium absorption. Thus, it’s worthwhile balancing the intake of this food group with other options such as dairy products and fortified alternative milk products.

How to Incorporate Calcium Into Your Diet

Calcium-Fortified Foods and Drinks

Food manufacturers often fortify certain products, such as breakfast cereals, orange juice, and plant-based milk alternatives, with calcium to boost their nutritional value. A single cup of calcium-fortified orange juice provides approximately 300mg calcium or 30% DV for calcium.

Foods Prepared with Calcium Sulfate

Calcium sulfate is a food preservative added to various processed foods. It is also used in the making of tofu, kefir, and cheese. One cup (240ml) of calcium sulfate-treated tofu offers up to 861 mg of calcium, meeting almost 80% of the recommended daily intake for most adult individuals.

Reading Food Labels for Calcium Content

Reading and comparing food labels regularly can help you identify food items that contain high amounts of calcium. Pay attention to the serving size and the level of calcium per serving. As per the FDA, if a product has 20% or more of the daily value of calcium, it is an excellent source of calcium.

Who is at Risk of Developing Calcium Deficiency?

People with Lactose Intolerance

Lactose intolerance is a condition where a person’s body cannot digest lactose, a sugar commonly found in dairy foods. As a result of this, people with lactose intolerance find it challenging to obtain enough calcium from dairy sources, putting them at a higher risk of developing calcium deficiency-related conditions like osteoporosis.

Women with Osteoporosis

Osteoporosis, a condition characterized by brittle bones, is more prevalent among women than men. Women over 50 years have a higher risk of developing this condition due to hormonal and lifestyle changes. Maintaining a diet rich in calcium-promoting food items alongside physical activity can reduce the risk of developing osteoporosis.

People with Inadequate Calcium Intake

Without adequate intake of calcium-rich foods or supplements, the body may leach calcium from bones, leading to weak, brittle bones and teeth, and increasing the risk of fractures and other health issues.

Calcium Supplements: Do You Need Them?

How Much Calcium Should You Get from Supplements?

The general advice is to meet your dietary needs of calcium from natural sources, after which supplements can be a viable option to help reach the recommended daily intake. However, an ideal dose will vary based on individual needs, and it’s essential to consult a healthcare provider before starting any new supplement regimen.

Types of Calcium Supplements

Calcium supplements mostly come in two types: calcium carbonate and calcium citrate. Calcium carbonate requires sufficient stomach acid to breakdown and absorb the calcium properly. This makes it a suitable option for people with ample stomach acid, and for consumption alongside meals. However, Calcium citrate is better absorbed by the body because it does not require stomach acid to absorb the calcium.

Calcium Supplement Safety and Side Effects

It is vital to adhere to the recommended dosage of calcium supplements. Taking high doses of calcium can lead to adverse side effects such as constipation, kidney stones, and calcium buildup in the blood vessels, leading to heart problems. Therefore, it is essential to talk to a healthcare provider before taking any calcium supplements.

Conclusion

In conclusion, calcium is essential to our overall well-being and good health. It is necessary to consume enough calcium-rich foods to meet your daily needs and prevent long-term health risks such as osteoporosis and other related conditions. 

By incorporating carefully selected foods and possibly calcium supplements into your diet, you can maintain optimal health and strong bones for years to come.
