Magnesium Deficiency is very common today. There are few reasons for this.
Stress greatly increases the need for Magnesium (see below). And there is certainly more stress in modern society than in the past.
The diet of most people is severly lacking in the types of foods that are rich in magnesium. Heavily processed foods contain less nutrients, including less magnesium. People who find it easier to pop a hot dog in the microwave for lunch are at risk of being deficient in many nutrients, including magnesium.
Foods that should be high in magnesium have much less magnesium (and other vitamins and minerals) than they did several generations ago due to soil depletion. Over the years, as nutrients are pulled from the soil and into the plants, there is less and less nutrients in the soil.
The following link tabulates the nutrient content as measured in an apple in 1914, 1963 and 1992. In 1992, the magnesium content was only 82.7% of what it was in 1914.
Soil depletion started before 1914 and has surely continued after 1992. So the amount of nutrients in food, including magnesium is much less than we need, especially when exposed to high levels of stess.
Stress and Magnesium Deficiency….
…a Viscious Cycle
Stress increases the need for magnesium. And Chronic stress can result in Magnesium Deficiency.
Unfortunately, magnesium deficiency leads to stress…..which leads to more magnesium loss……. It is a vicious cycle.
