Calcium plays a vital role in maintaining overall health, with its primary function being to build and maintain bones and teeth. While calcium is one of the essential nutrients our bodies need, the debate on whether to take calcium supplements or rely on dietary sources for adequate daily intake continues.
The Importance of Calcium
Calcium is crucial for various functions within the body, such as facilitating blood clotting, nerve cell function, muscle contraction, and maintaining a regular heartbeat, in addition to contributing to bone health. Inadequate calcium intake may lead to weakening of the bones, a condition known as osteoporosis. Osteoporosis has a higher prevalence rate among the elderly population and post-menopausal women, who often consume less than the recommended amount of calcium.
Recommendations from Experts
According to Douglas C. Bauer, M.D., a researcher at the University of California San Francisco, a high calcium diet is the desired method to meet the recommended dosage of calcium. The Institute of Medicine suggests a daily intake of 1,200 mg for post-menopausal women over 50 and men over 70.
Bauer advises trying to reach this daily intake through calcium-rich food sources, such as kale, broccoli, and bok choy, rather than taking calcium supplements. However, if getting enough calcium from dietary sources is not possible, Bauer suggests using calcium supplements as they are most likely safe and not associated with cardiovascular outcomes.
The Controversy over Calcium Supplements
The debate surrounding calcium supplements came to the forefront due to a 2010 study that seemed to show an increased risk of heart-related issues for those taking supplements. However, subsequent research has not been able to reach the same conclusions, so the question remains open-ended.
While calcium supplements might suffice for those unable to meet their calcium needs through diet, it is essential to understand the potential downsides of supplement usage. For instance, high calcium intake from supplements has been linked to kidney stones, constipation, and potential interference with iron and zinc absorption.
Getting the Right Amount of Calcium Through Diet
Incorporating calcium-rich foods in your daily meals is the best way to reach the recommended calcium intake. Here are some options to consider:
- Dairy products: Milk, cheese, and yogurt are excellent sources of calcium.
- Leafy green vegetables: Spinach, kale, collard greens, and broccoli are rich in calcium.
- Fish and seafood: Sardines and salmon (with bones) contain high amounts of calcium.
- Fortified foods: Foods and beverages like orange juice, almond milk, and soy milk, are often infused with calcium.
Key Takeaways
In conclusion, calcium is a vital part of a healthy lifestyle, and it is necessary to obtain sufficient amounts, especially for specific populations like post-menopausal women and the elderly. While the debate regarding calcium supplements continues, consuming calcium-rich foods should be the first line of defense in meeting your daily calcium needs. In instances where dietary intake may fall short of providing the necessary amount of calcium, supplements can bridge the gap. Consult with your healthcare provider to determine the best course of action for your calcium needs based on your unique lifestyle and dietary requirements.
