Magnesium deficiency can sneak up on you, influenced by what you eat, the availability of magnesium-rich foods, certain illnesses, medications, and even your genes. Detecting low magnesium levels can be tricky, so it’s crucial to understand the risk factors to prevent it.
Causes of Magnesium Deficiency
Dietary Factors:
Diets low in magnesium, and consuming too many processed foods and sodas.
Drinking soft water, which has fewer minerals.
Taking too many calcium supplements can mess with magnesium absorption.
Health and Lifestyle:
Struggling with alcohol and other addictions.
Aging, illness, and stress, which ramp up your body’s need for magnesium.
Digestive and genetic disorders that make it hard to absorb magnesium.
The American Diet and Magnesium
The typical American diet often falls short on magnesium, with most people getting less than two-thirds of what they need. This is due to a diet high in fat, sugar, salt, synthetic vitamin D, phosphates, protein, and calcium supplements. These dietary habits not only reduce magnesium intake but also increase the body’s demand for it.
Magnesium-rich foods like whole grains, leafy greens, nuts, and seeds are becoming rare in modern diets, often replaced by processed and convenience foods.
The Impact of Processed Foods
Processed foods and drinks, especially those high in sugar and phosphates, can drain your magnesium levels. For example:
High-fat diets reduce magnesium absorption in your intestines.
High sugar intake makes your kidneys flush out more magnesium.
Carbonated drinks bind magnesium, making it unusable by your body.
Water and Magnesium
Drinking water with high mineral content can boost your magnesium intake and improve health. However, soft water can contribute to magnesium deficiency. The World Health Organization acknowledges the importance of magnesium in drinking water, particularly for heart health.
Medications and Magnesium Deficiency
Certain medications can deplete your magnesium levels by impairing absorption or increasing excretion. These include:
Diuretics
Antibiotics
Painkillers
Corticosteroids
Medications for heart failure and irregular heartbeat
Illness, Stress, and Aging
Stressful situations like surgery, burns, liver disease, diabetes, and hormonal imbalances increase your body’s need for magnesium. Aging naturally lowers stomach acid levels, which can affect magnesium absorption.
Digestive Disorders
Conditions like Crohn's disease, celiac disease, and other digestive disorders can lead to magnesium malabsorption. People with these conditions often need more magnesium to compensate for the loss.
Too Much Calcium
Calcium supplements, often taken to prevent bone loss, can deplete your magnesium levels if not balanced correctly. A 1:1 ratio of calcium to magnesium is usually recommended, especially for those with high calcium intake.
Recognizing the Risk Factors
Since it’s hard to test accurately for magnesium deficiency, it’s important to consider both test results and risk factors. Knowing the causes of magnesium deficiency can help you make informed decisions about your diet and supplements.
For those without kidney disease, magnesium supplements are generally safe, with the main side effect being loose stools if you take too much. Topical magnesium can avoid digestive issues entirely. By understanding the risk factors and dietary influences on magnesium levels, you can take proactive steps to ensure you get enough of this vital mineral.
