WHEN PHYSIOLOGY MEETS THE BUILT ENVIRONMENT: THE PHOSPHORUS STORY

Area of Science:

• Nutrition Science
• Public Health
• Environmental Health

Background:

• Disorders of phosphorus metabolism are independent risk factors for cardiovascular disease, kidney disease, and mortality.
• Excessive dietary phosphorus intake is prevalent and disrupts phosphorus balance, prompting interest in dietary phosphorus restriction for health.
• Socioeconomic status and built environment factors significantly influence dietary phosphorus consumption and overall diet quality.

Purpose of the Study:

• To highlight the significant contribution of excessive dietary phosphorus intake to health risks.
• To examine the role of socioeconomic status and the built environment in modulating phosphorus intake.
• To underscore the necessity of addressing environmental challenges in accessing healthy foods for phosphorus management.

Main Methods:

• Epidemiological research analysis
• Socioeconomic status assessment
• Built environment factor evaluation

Main Results:

• A direct correlation exists between income, education, and diet quality concerning phosphorus intake.
• Built environment factors like food outlet accessibility and fast-food restaurant density impact phosphorus consumption.
• Diet quality is strongly linked to the built environment, affecting phosphorus intake.

Conclusions:

• Reducing excess phosphorus intake is a potential strategy for improving cardiovascular and kidney health.
• Effective strategies must consider socioeconomic and built environment determinants of diet quality.
• Addressing built environmental barriers to healthy food access is essential for managing phosphorus intake and improving health outcomes.
