    Research into trace elements has greatly benefited agriculture and human health, leading to discoveries like vitamin B12. Understanding the molecular basis of trace element deficiencies is crucial for animal and human health.

    Area of Science:

    • Nutritional Science
    • Biochemistry
    • Animal Health

    Background:

    • The discovery of cobalt's essentiality for ruminants highlights the agricultural benefits of trace element research.
    • Trace element research led to the identification of vitamin B12, crucial for human health and treating pernicious anemia.
    • New essential trace elements are continually being discovered, but their biochemical roles and health implications remain largely unknown.

    Purpose of the Study:

    • To emphasize the importance of trace element research in human and animal health.
    • To highlight the gap in understanding the biochemical mechanisms of newly discovered essential trace elements.
    • To advocate for greater attention to inorganic micronutrients in nutrition policy.

    Main Methods:

    • Review of historical discoveries in trace element nutrition.

    Related Experiment Videos

  • Analysis of current knowledge gaps regarding new trace elements.
  • Discussion of the link between molecular mechanisms and clinical deficiencies.

    • Main Results:

    • Trace element research has yielded significant benefits for agriculture and human health.
    • Deficiencies or imbalances in trace elements pose risks to human and animal health.
    • There is a lack of understanding regarding the biochemical functions and health impacts of newly identified essential trace elements.

    Conclusions:

    • A clear understanding of the molecular and biochemical pathways of trace elements is essential for addressing human and animal health issues.
    • Nutrition policy must give greater consideration to inorganic micronutrients alongside macronutrients.
    • Further research is needed to elucidate the roles of new trace elements and their impact on health.
