Dietary intake of essential minerals like calcium, phosphorus, and zinc was low in Chinese children and adults in 1992. Regional variations in mineral intake were significant across China.

Area of Science:

  • Human Nutrition
  • Dietary Assessment
  • Mineral Metabolism

Context:

  • The 1992 total diet study in China assessed macro and trace element intake.
  • Data was collected across four distinct geographical districts.
  • Seasonal variations and age-specific intake levels were analyzed.

Purpose:

  • To evaluate the dietary intake of ten macro and trace elements.
  • To identify potential nutritional deficiencies in different age groups and regions.
  • To explore relationships between mineral intake ratios and health outcomes like iron deficiency anemia.

Summary:

  • Low intakes of calcium (Ca), phosphorus (P), potassium (K), magnesium (Mg), zinc (Zn), selenium (Se), and copper (Cu) were observed in children.
  • Adults exhibited insufficient intake of Ca, P, and Zn.

  • While other elements met or neared Recommended Dietary Allowance (RDA) levels, significant regional disparities in intake were noted across the four districts.

    • Impact:

    • Highlights critical nutritional gaps in the Chinese population, particularly for vulnerable groups.
    • Provides baseline data for public health interventions aimed at improving mineral status.
    • Informs future dietary guidelines and fortification strategies to address deficiencies and imbalances.
