⏳ Geroscience: Disease as Ageing or Ageing as Disease — a New Longevity Paradigm
Why ageing is considered a common factor of all age-related diseases
Geroscience is a scientific paradigm that treats ageing as a common biological factor underlying most chronic age-related diseases: cardiovascular, metabolic, neurodegenerative and oncological. The idea is that by slowing ageing, you can simultaneously lower the risk of many diseases.
What is geroscience
Traditional medicine treats diseases separately. Geroscience offers another view: age is the main common risk factor of most diseases. The term unites research on ageing biology and the search for interventions that slow this process.
- Age is the leading risk factor of chronic diseases.
- Slowing ageing can influence many diseases at once.
- Targets are studied: senescent cells, metabolism, epigenetics.
- Geroscience is an interdisciplinary field.
Hallmarks of ageing
Geroscience highlights several "hallmarks of ageing": genomic instability, telomere shortening, epigenetic changes, loss of proteostasis, mitochondrial dysfunction, senescent cells, stem cell exhaustion and metabolic disruption.
| Hallmark | Essence | Intervention |
|---|---|---|
| Senescent cells | "Zombie cells" releasing inflammation | Senolytics, quercetin |
| Mitochondria | Reduced cell energy | CoQ10, NAD+ |
| Epigenetics | Change in gene activity | Lifestyle, methylation |
| Metabolism | Insulin resistance | Berberine, diet |
Biological age markers
Biological age differs from calendar age. To estimate it, epigenetic clocks, telomere length, inflammation markers (such as C-reactive protein), blood sugar and lipids are used.
- Epigenetic clocks are one of the key markers.
- Telomere length reflects cellular ageing.
- Inflammation markers (hs-CRP) are linked to age.
- A panel of tests gives an estimate of biological age.
Role of nutraceuticals
Within geroscience, substances that may support ageing-related mechanisms are studied: NAD+ precursors (NMN, NR), senolytics (quercetin, fisetin), sirtuin activators (resveratrol) and metabolic regulators (berberine).
- NAD+ precursors — support mitochondria and DNA repair.
- Senolytics — clearance of "zombie cells".
- Sirtuins — link to metabolism and longevity.
- Berberine — regulation of glucose and metabolism.
Food: what supports
Nutrition is a key factor in slowing age-related processes. Polyphenols, omega-3, fibre and micronutrients support antioxidant defence and metabolism.
| Food | Compound | Comment |
|---|---|---|
| Berries | Anthocyanins | Antioxidants, a handful a day |
| Fatty fish | Omega-3 | 2–3 servings a week |
| Nuts | Polyphenols, magnesium | A handful a day |
| Vegetables | Vitamins, fibre | Variety daily |
| Turmeric | Curcumin | Anti-inflammatory |
How much to eat
- Berries: ~100–150 g a day — a good portion of antioxidants.
- Fatty fish: ~200 g a week (or 2 servings) covers omega-3.
- Nuts: a handful (~30 g) daily gives polyphenols and magnesium.
- Vegetables: 400–500 g of varied vegetables and fruit a day.
Practice and conclusions
- Regular physical activity is the most studied longevity factor.
- Control of sleep, stress and body weight.
- Nutrition focused on plants, omega-3 and fibre.
- Tracking biological age markers.
- Nutraceuticals are an auxiliary tool, not a replacement for lifestyle.
What is geroscience?
A paradigm that treats ageing as a common factor of chronic age-related diseases.
How is ageing linked to disease?
Age is the main common risk factor of most chronic diseases; slowing it can influence many at once.
What is biological age?
An estimate of body state based on markers (epigenetics, telomeres, inflammation), different from calendar age.
Which nutraceuticals are studied?
NAD+ precursors, senolytics, sirtuins, berberine.
What are senescent cells?
"Zombie cells" that stopped dividing but release inflammatory substances.
How does diet affect ageing?
Polyphenols, omega-3, fibre and micronutrients support antioxidant defence and metabolism.
Can ageing be slowed?
Lifestyle, diet and activity can slow age-related processes; nutraceuticals are auxiliary.
What is Healthspan?
The period of active health without disease — the main goal of geroscience.
Which tests to take?
Glucose, lipids, hs-CRP, vitamin D, sometimes telomere length and epigenetic clocks.
Are experiments safe?
Many interventions are still studied — do not replace proven treatment without a doctor.
