At some point, calcium supplementation became popular, with methods ranging from bone broth to soy milk. But why does our body need calcium?
What causes calcium loss?
1. Declining sex hormone levels
As we age, our bodies produce less sex hormones. This weakens their ability to counteract parathyroid hormone, which promotes bone demineralization. Consequently, calcium loss can easily occur, leading to osteoporosis and related conditions.
2. Consumption of pickled foods
Many people enjoy eating pickled foods regularly. Long-term consumption of these foods can lead to calcium loss in the body. This is because pickled foods typically contain high levels of salt. Excessive salt intake impairs the body's ability to absorb calcium from food.
For every gram of sodium excreted, the body loses 26 milligrams of calcium. The more sodium excreted, the greater the calcium depletion. Long-term consumption of high-salt foods compromises the calcium essential for bone health, weakening bone strength.
3. Nutritional Deficiencies
Digestive function declines with age, leading to nutritional deficiencies and chronic insufficiency in proteins, calcium, phosphorus, vitamins, and other micronutrients. Long-term protein deficiency can reduce plasma protein levels, hindering bone matrix synthesis. Combined with inadequate calcium intake, these factors contribute to gradual calcium loss from bones.
4. Regular consumption of beverages
Long-term intake of coffee, strong tea, and similar beverages can also contribute to calcium loss. The theophylline in tea inhibits calcium absorption, reducing calcium levels in the body. Meanwhile, caffeine in coffee accelerates calcium loss and increases urinary calcium excretion, further exacerbating calcium depletion.
What are the correct methods for calcium supplementation?
Having understood some common causes of calcium loss, let's explore how to supplement calcium effectively.
First, ensure adequate sun exposure for calcium supplementation. Sunlight promotes vitamin D synthesis and calcium absorption, making it an excellent method for calcium replenishment.
Second, incorporate calcium-rich foods into your daily diet. Common choices include soy products and dairy items, which are rich in calcium and provide effective supplementation. However, note that bone broth is not recommended for calcium intake—it offers little benefit and may contribute to weight gain or elevated uric acid levels.
Lastly, consistent exercise is crucial. Moderate physical activity promotes calcium absorption in the body, making it essential for those seeking to supplement calcium.
Calcium supplementation can be achieved through daily lifestyle adjustments. Unless you experience abnormal symptoms or suffer from severe calcium deficiency, there's no need to take supplements or medications for calcium. If you do require supplementation, it should be done under the guidance of a healthcare professional.
