Reasons for deficiency
- The use of herbicides and pesticides that kill off worms and bacteria in the soil. It is the bacteria in the soil that make it possible for plants to absorb minerals.
- Potash (potassium chloride or potassium carbonate) being used as a fertiliser. This is taken up by plants in preference to Calcium and Magnesium.
- Soil erosion as Magnesium is leached out by heavy rain.
- Acid rain (as occurs in air pollution) contains Nitric Acid. In the soil Nitric Acid reacts with Calcium and Magnesium to neutralise excess nitric acid. Eventually Calcium and Magnesium become depleted and the nitric acid reacts with Aluminium oxide in the soil. A reactive Aluminium builds up replacing Calcium and Magnesium in the plant. Calcium is needed for cell wall strength and Magnesium for chlorophyll for photosynthesis. So plants may grow taller and faster but are weak and lack chlorophyll.
- Food processing decreases Magnesium. It is lost in grains during milling and making of white flour. It is also lost from vegetables when they are boiled.
- Fluoride in water and toothpastes binds to Magnesium making it unavailable to the body. Fluoride is insoluble and replaces Magnesium in bone and cartilage.
- Stress. Increased stress results in decreased stomach acid and decreased hydrochloric acid in the stomach results in decreased absorption of Magnesium. Commonly consumed antacids neutralise Hydrochloric acid, decreasing Magnesium absorption.
- Magnesium absorption is altered by an unhealthy intestine for example; IBS, leaky gut, gluten and casein sensitivities, funguses & parasites, vitamin D deficiency and the formation of Magnesium soaps in the stools as Magnesium binds to unabsorbed fats.
- Some foods can block the absorption of Magnesium. High protein diets can decrease Magnesium absorption. Tannins in tea bind and remove minerals including Magnesium. Oxalic acid in rhubarb, spinach and chard and phytic acid in cereals and soy also block absorption of Magnesium.
- Junk foods, particularly sugary foods all use up extra Magnesium.
- Saturated and trans fats alter cell wall integrity, making it more rigid which affects receptor site function and prevents nutrients from getting into or out of the cell.
- Drugs - some drugs eliminate Magnesium. Antacids, antibiotics and diuretics all cause Magnesium depletion. Large consumption of caffeine and alcohol cause depletion with their diuretic effect.
- Hypokalaemia (low potassium levels) can increase urinary Magnesium loss.
- Body size - the larger the body, the larger the Magnesium pool, then the lower the absorption from any source.
