Excessive sodium consumption not only affects blood pressure but also significantly impacts bone health. This article reveals the effects of sodium on bones, along with recommendations on how to control intake and maintain bone health to prevent osteoporosis.

1. The Effect of Sodium on Bone Health

Excessive sodium consumption significantly harms bone health. Research from Mahidol University, in collaboration with the Synchrotron Light Research Institute, found that excessive sodium intake and hypertension can negatively affect bones, leading to osteoporosis. This study used 3D X-ray imaging technology to examine the bones of laboratory rats with hypertension, showing that the microstructure of their bones was more porous than that of normal rats.

1.1 Sodium and Calcium Excretion from the Body

When the body receives too much sodium, it leads to increased calcium excretion. This process occurs because sodium binds with calcium in the body and is excreted through urine. Continuous calcium loss adversely affects bone strength, especially among at-risk groups such as postmenopausal women, the elderly, and those already at risk for osteoporosis.

1.2 Bone Density Loss

High sodium intake not only leads to calcium loss but also directly affects bone density. Research shows that people with high sodium consumption tend to have lower bone density, increasing the risk of developing osteoporosis. Furthermore, hypertensive individuals are at an increased risk for bone mass loss due to the relationship between high blood pressure and calcium metabolism in the body.

1.3 Bone Mineral Density Testing

Measuring bone mineral density (BMD) is crucial for diagnosing osteoporosis, a condition characterized by decreased bone density, making bones fragile and more prone to fractures even from minor accidents. This test can be performed using a device called DXA (Dual-energy X-ray Absorptiometry), a standard method recognized by the WHO due to its high accuracy and low radiation dose.

BMD assessments focus on areas prone to fractures such as the spine, hip, and wrist, with results presented as a T-score that compares the individual’s bone density against healthy adults aged 30. A T-score above -1 is considered normal; between -1 and -2.5 indicates osteopenia; and below -2.5 indicates osteoporosis.

This assessment is suitable for individuals at high risk for osteoporosis, such as postmenopausal women, those over 65 years old, men over 70 years old, individuals with a history of fractures, or those on long-term steroid therapy. The test is convenient, requires no prior preparation, takes about 10-15 minutes, and results can be known immediately.

1.4 Preventing Calcium Loss

To prevent calcium loss and maintain bone health, it is recommended to:

Control sodium intake: Reduce consumption of high-sodium foods such as processed foods, pickled foods, and ready-to-eat meals.
Increase calcium intake: Consume foods rich in calcium such as dairy products, dark leafy greens, and small fish.
Exercise regularly: Weight-bearing exercises like walking, running, or aerobics help strengthen bones.
Get sunlight: Sunlight helps the body produce vitamin D, essential for calcium absorption.
Avoid risk factors: Reduce alcohol consumption and quit smoking as these negatively affect bone health.

2. The recommended daily sodium intake to prevent osteoporosis

In today’s world, consuming high-sodium foods has become a significant health concern, especially when it comes to its impact on bone health. Regular consumption of high-sodium foods can negatively affect bone strength and increase the risk of developing osteoporosis. Therefore, understanding the appropriate amount of sodium intake and how to control it is crucial.

2.1 Appropriate Sodium Intake

According to health organizations, the recommended sodium intake for adults should not exceed 2,000 milligrams per day, which is equivalent to about one teaspoon of salt or no more than four teaspoons of fish sauce. For children, the recommended sodium intake should not exceed 1,900 milligrams per day.

However, in reality, most people consume 2-3 times more sodium than the recommended amount, which is a major cause of various chronic diseases, including adverse effects on bone health.

2.2 Effects of Excessive Sodium Consumption

Consuming too much sodium can have several negative health consequences:

Increased risk of high blood pressure: Excess sodium thickens the blood and draws water out of cells, leading to elevated blood pressure.
Increased kidney strain: The kidneys have to work harder to excrete excess sodium, increasing the risk of chronic kidney disease and kidney failure.
Impact on cardiovascular system: High sodium intake increases the risk of heart and vascular diseases.
Effects on bone health: High sodium consumption may cause the body to lose more calcium, an essential mineral for bones, increasing the risk of osteoporosis.

2.3 Methods to Reduce Sodium in Food

There are several ways to reduce sodium in your diet:

Choose natural foods: Eat fresh, unprocessed foods to avoid added sodium in manufacturing processes.
Reduce use of seasonings: Decrease the amount of salt, fish sauce, seasoning sauces, and monosodium glutamate in cooking.
Read nutrition labels: Choose low-sodium products. Main meals should not contain more than 600 milligrams of sodium, and snacks should not exceed 200 milligrams.
Cook at home: Preparing meals at home allows better control of sodium content compared to buying ready-made meals or eating out.
Use herbs and spices: Enhance food flavors with herbs and spices instead of using salt or high-sodium seasonings.
Avoid processed foods: Reduce consumption of canned foods, frozen meals, and snacks, which often contain high levels of sodium.

3. Warning Signs of Excessive Sodium Intake: Risk of Osteoporosis

Consuming too much sodium is a common health issue today, especially in societies that favor processed and fast foods. Regularly eating high-sodium foods can lead to various health problems, including high blood pressure, kidney disease, and osteoporosis. Therefore, recognizing your body’s warning signs is crucial to adjust your eating habits in time.

3.1 Frequent Thirst

A clear indicator that you may be consuming too much sodium is frequent thirst. When your body receives excess sodium, it tries to maintain balance by drawing water from cells to dilute the sodium in your blood, making you feel thirstier than usual. Additionally, drinking more water is your body’s way of trying to flush out excess sodium through urine.

Frequent thirst can also be a symptom of other conditions, such as diabetes or dehydration. If you find yourself unusually thirsty, especially if the symptom persists despite drinking water, consult a doctor to determine the underlying cause.

3.2 Swollen Hands and Feet

Another warning sign of excessive sodium intake is swelling in your hands and feet. When your body receives too much sodium, it retains water, causing swelling in various parts of the body, particularly in the hands and feet.

This swelling occurs as your body attempts to maintain mineral balance by drawing water into the bloodstream and tissues, resulting in fluid retention. Besides hands and feet, swelling may also occur in the face or other parts of the body.

3.3 Headaches

Consuming too much sodium can lead to headaches, especially in those prone to high blood pressure. When the body receives excess sodium, it draws more water into the bloodstream, increasing blood volume and raising pressure in blood vessels.

This increased pressure can cause headaches, particularly in the back of the head or temples. Headaches may also result from rapid changes in the body’s sodium levels, which affect the nervous system.

Controlling sodium intake is key to maintaining healthy bones. A balanced diet, regular exercise, and avoiding risk factors can effectively prevent bone mass loss and reduce the risk of osteoporosis. Remember that adequate calcium intake is also crucial for bone health, so ensure your diet includes calcium-rich foods or supplements as recommended by your healthcare provider.
