A possible relationship between high-extraction cereal and rickets and osteomalacia

Area of Science:

• Nutritional Science
• Bone Metabolism
• Food Chemistry

Background:

• Rickets and osteomalacia are bone diseases linked to impaired mineralization.
• High-extraction cereals are a staple food, but their potential impact on bone health is debated.
• Previous research suggested an
• anti-calcifying substance
• in these cereals, but its identity remains unclear.

Purpose of the Study:

• To investigate the potential causal relationship between high-extraction cereal consumption and the development of rickets and osteomalacia.
• To explore the role of vitamin D status in this relationship.
• To identify the specific component within high-extraction cereals responsible for rachitogenic effects.

Main Methods:

• The study likely involved observational data or controlled dietary interventions examining cereal intake and bone health markers.
• Vitamin D levels were assessed to determine their influence.
• Analysis focused on identifying potential inhibitory factors in cereal composition.

Main Results:

• A strong association, possibly causal, was found between high-extraction cereal intake and rickets/osteomalacia.
• This effect appears more pronounced in individuals with borderline vitamin D status.
• Dietary phytate is less likely to be the sole causative agent; phytate-derived polyphosphate esters or phosphorus are potential culprits.

Conclusions:

• The findings support Mellanby's original hypothesis of an
• anti-calcifying substance
• in high-extraction cereals.
• Further research is needed to pinpoint the exact rachitogenic component.
• Dietary management and vitamin D supplementation may be crucial for populations consuming high-extraction cereals.
