Nutrition
Dietary patterns are widely studied in metabolic and aging research; most findings are observational.
Dietary advice should come from a qualified professional and rest on clinical evidence, not on an epigenetic result alone.
Aging biology
When metabolism and aging intersect
Metabolic health is one of the most studied areas in aging research. This page explains the biology, the strength of the evidence, and where epigenetic information fits.
A proposed pathway
From metabolic dysfunction to biological aging signals
This sequence is a mechanistic framework drawn from research. It describes plausible links, not a diagnosis for any individual.
Metabolic dysfunction
Disturbed regulation of glucose and lipids.
Insulin resistance
Tissues respond less effectively to insulin.
Hyperinsulinaemia
The body compensates with higher circulating insulin.
Adipose dysfunction
Changes in fat tissue behaviour, including visceral adiposity.
Inflammatory signalling
Persistent low grade inflammatory activity.
Cellular stress
Oxidative and mitochondrial stress responses.
Epigenetic alterations
Methylation changes reported in association studies.
Biological aging signals
Measurable signals, meaningful only within clinical context.
Reading the evidence
Each link in this chain sits at a different level of evidence. Some are well established physiology; others are associations or hypotheses still under study.
Clinical perspective
Epigenetics adds a layer; it does not replace one
Conventional measures remain the foundation of metabolic assessment. Epigenetic information may offer additional biological context.
Established clinical measures
- HbA1c
- Fasting glucose
- Fasting insulin
- Lipid profile
- Blood pressure
- Body composition
- Liver markers
- Clinical history
These are interpreted by a physician and remain the reference for clinical decisions.
Biology studied alongside them
- Glucose regulation
- Insulin signalling
- Visceral adiposity
- Lipid metabolism
- Mitochondrial function
- Inflammation
- Oxidative stress
- Sleep and activity
These topics are educational context. Their appearance here does not mean each is measured by the VERITAS EPI assay.
Factors in aging research
What the research says about everyday factors
02
Physical activity
Among the most consistently studied factors in cardiometabolic and aging research.
Associations with methylation patterns have been reported. They do not translate into a predicted change for any one person.
03
Sleep and stress
Sleep quality and psychological stress are associated with inflammatory and biological measures.
The strength of evidence varies between studies, and findings are presented with that in mind.
04
Inflammation and cardiovascular health
Inflammatory biology connects cardiovascular and aging research along several described pathways.
Cardiovascular risk is assessed clinically with validated tools and conventional measurements.
