Why Modern Diets Are Low in Magnesium (Even If You Eat Healthy)
Magnesium deficiency is common — even among people who believe they eat well.
This isn’t simply about poor diet choices.
It’s about structural changes in:
-
Food production
-
Soil quality
-
Food processing
-
Lifestyle stress
Magnesium intake has declined over the last century.
Let’s look at why.
In Short
• Soil mineral depletion reduces magnesium content in crops
• Food processing removes magnesium
• Refined diets contain less magnesium
• Stress increases magnesium utilisation
• Even “healthy” diets may fall short
1️⃣ Soil Depletion
Modern agricultural practices often prioritise yield over mineral density.
Repeated cropping without mineral replenishment can reduce:
-
Magnesium
-
Zinc
-
Selenium
When soil magnesium declines, plant magnesium declines.
That means even vegetables may contain less magnesium than historically.
This doesn’t mean food is “bad.”
It means mineral density varies.
2️⃣ Food Processing
Magnesium is concentrated in:
-
Whole grains
-
Seeds
-
Nuts
-
Legumes
Refining removes:
-
Bran
-
Germ
-
Mineral-rich components
White flour, polished rice and ultra-processed foods contain significantly less magnesium than their whole equivalents.
3️⃣ Lower Calorie Intake
Many modern diets are:
-
Lower in total calories
-
Higher in refined carbohydrates
-
Lower in mineral density
When calorie intake drops, micronutrient intake often drops too.

4️⃣ Chronic Stress
Magnesium is involved in:
-
Stress hormone regulation
-
ATP production
-
Nervous system balance
Chronic stress may increase magnesium utilisation.
This can create a depletion cycle:
Stress → magnesium use → lower reserves → increased sensitivity to stress
5️⃣ Intestinal Competition
Modern supplement stacks often combine:
-
Calcium
-
Iron
-
Zinc
-
Magnesium
Into one dose.
Mineral competition may reduce fractional absorption.

Can You Get Enough Magnesium From Food?
Yes — in theory.
Magnesium-rich foods include:
-
Pumpkin seeds
-
Almonds
-
Spinach
-
Black beans
-
Dark chocolate
However:
-
Portion size matters
-
Bioavailability varies
-
Absorption depends on digestive health

When Supplementation Makes Sense
Supplementation may be useful if:
• Dietary intake is inconsistent
• Stress load is high
• Symptoms are present
• Intake tracking shows shortfall
The goal is not excess.
The goal is sufficiency.

FAQ
Why are so many people low in magnesium?
Modern agriculture, food processing and chronic stress contribute to lower intake and higher utilisation.
Can I get enough magnesium from food?
Yes, but many people fall short without consistent whole-food intake.
Is magnesium deficiency common?
Subclinical insufficiency is relatively common in developed countries.
Final Thoughts
Magnesium intake didn’t collapse overnight.
It shifted gradually — through agriculture, processing and lifestyle change.
Eating well still matters.
But mineral density and stress load matter too.
Understanding that gap is the first step toward closing it.
