Conceptual Framework
Conceptual Framework
Understanding the role of nutrition in canine aging requires conceptual clarity. The Canine Geronutrition Initiative distinguishes between biological mechanisms of aging, pharmaceutical interventions, and nutritional research contexts.
This framework provides structure for interpreting emerging data responsibly.
1. Aging Biology in Dogs
Aging is characterized by progressive changes in cellular maintenance, metabolic regulation, and tissue resilience. These changes may include:
-
These processes are studied across species and provide a comparative foundation for canine aging research.
2. Pathway Modulation (Pharmaceutical Context)
Pharmaceutical longevity research often targets specific signaling pathways, such as:
-
These approaches involve direct modulation of biological signaling mechanisms and are evaluated under regulatory and clinical frameworks.
-
Pharmaceutical interventions are distinct from nutritional strategies in both mechanism and regulatory classification.
3. Substrate Support (Nutritional Context)
Nutritional research focuses on substrate availability and physiological support. Rather than modifying signaling pathways, dietary strategies may influence:
-
Substrate support does not override genetic or environmental determinants of aging. It represents one dimension of research within a broader biological landscape.
4. Biomarker Evaluation
In canine geronutrition research, biomarkers are used to assess measurable biological parameters. These may include:
Biomarkers provide insight into biological patterns under controlled study conditions. They do not directly equate to lifespan outcomes or therapeutic effects.
5. Integrative Perspective
The Initiative recognizes three distinct domains:
Each operates within separate scientific and regulatory frameworks
Nutritional geroscience seeks to understand how dietary components interact with biological systems — without replacing medical treatment or asserting lifespan extension.
Scientific rigor requires clear differentiation among these domains.
