Summary
Chris Masterjohn challenges the widespread medical assumption that nutritional deficiencies are rare in developed countries. He presents evidence showing that subclinical deficiencies are common and significantly impact health outcomes, arguing for better nutritional assessment in clinical practice.
Key Points
- Subclinical nutritional deficiencies remain widespread in developed countries
- Standard blood tests often miss marginal deficiencies
- Modern food processing and soil depletion contribute to nutrient gaps
- Key commonly deficient nutrients include magnesium, zinc, vitamin D, and B vitamins
- Functional biomarkers provide better assessment than serum levels alone
