CAM !

Introduction

  • The lecture will cover the differences between traditional medicine and complementary and alternative medicine (CAM).
  • The importance of understanding CAM and traditional medicine for future nutrition labs and health practices.

Concepts of Medicinal Plants and CAM

  • Medicinal Benefit of Plants:
    • Definition: Medicinal refers to biological effects on the body when taken in high doses (affecting the brain, vasculature, gut health, etc.).
    • Many pharmaceuticals originate from plants.
  • Mindfulness & Body Practices:
    • Examples: mindfulness, meditation, yoga are believed to help mind, body, and soul.
  • Chiropractic Care:
    • Viable for musculoskeletal pain management.
    • Personal experience shared regarding chiropractic treatment for shoulder pain and neck stiffness.
  • Vitamin and Supplement Use:
    • Inquiries about students’ use of vitamins and supplements.

Definitions of Key Terms: Complementary vs. Alternative

  • Complementary Medicine:
    • Used in addition to traditional treatment; supports prescription medications.
  • Alternative Medicine:
    • Used instead of conventional medical care; may avoid prescribed treatments.
    • Example: Choosing herbs over prescribed medications for a stomach ulcer.
  • Personal Anecdote: Speaker’s mother has rarely seen a doctor and often relies on supplements.

Growth and Recognition of CAM

  • Increasing acceptance of CAM by institutions like the Natural Institute of Health (NIH) and Health Canada.
  • A cautionary note on the potential for misleading claims due to advertising and marketing.
  • The necessity of evaluating evidence before investing in natural products due to risks of being misled.

Assessing Claims about Natural Products

  • Importance of questioning and verifying product claims on labels.
  • Encouragement to read a suggested article by a PhD at McGill discussing evidence in natural products claims.
  • A call to adopt an "open-minded skeptic" approach towards evaluating CAM practices.

Importance of Evidence

  • Evidence Levels:
    • The mention of a pyramid structure regarding evidence levels.
    • Critical to evaluate safety and efficacy of treatments before deciding on them.
  • Discussion on the thresholds for evidence:\n - Evidence-based products may not always be thoroughly tested for quality and effectiveness.

Health Canada Designations

  • Designations for products sold in Canada:
    • DIN (Drug Identification Number):
    • Indicates high-quality, evidence-based traditional medicine.
    • NPN (Natural Product Number):
    • Represents natural health products with insufficient evidence for the DIN mark.
    • DINHM (Homeopathic Medicine):
    • Indicates homeopathic products which use extremely diluted ingredients.

Products and Their Efficacy

  • Homeopathy:
    • A modality claiming small doses of substances could trigger healing responses.
  • Examples of CAM Treatments:
    • Echinacea: Thought to help with viral infections but requires scrutiny of evidence supporting its efficacy.
    • Importance of assessing personal experiences against clinical findings.
    • Previous clinical trials confirming effectiveness showed stronger results when taken early.

CAM Categories and Subcategories

  • Different forms of CAM exist:
    • Herbs and supplements.
    • Mind-body techniques: massage, acupuncture, chiropractic, etc.
    • Energy therapies and holistic claims (some questionable).

Prevalence of CAM Usage in Canada

  • Approximately 80% of Canadians have adopted various CAM practices.
  • Frustrations with traditional medicine leading to increased CAM usage.
  • Discussion of the projected financial growth in the CAM industry globally.

Risks and Caution in CAM

  • Health Canada lacks the ability to ensure quality and safety of CAM products, raising concerns for public health.
  • Risk-benefit analysis heavily encouraged when considering CAM treatments.
  • Anecdotal Example: The surprising discovery of a treatment for type 2 diabetes from lizard venom leading to a legitimate pharmaceutical breakthrough (Ozempic).

Conclusion

  • The necessity of being informed consumers and seeking evidence-based information about CAM products.
  • Encouragement to use resources like the National Institute of Health for further research and understanding of CAM practices.
  • Final thoughts on making informed decisions regarding both traditional and complementary medicine strategies.
