Chronic, low-grade inflammation (inflamm-aging) driven by cytokine dysregulation, oxidative stress, and senescent cells is a primary mechanism underlying aging and age-related diseases such as cardiovascular disease, diabetes, and neurodegeneration.
Focus on lifestyle factors that reduce chronic inflammation: adopt a Mediterranean-style diet rich in omega-3s, engage in regular exercise to upregulate autophagy, and manage stress. These approaches support the body's natural resolution of inflammation rather than just suppressing symptoms.
Cytokine dysregulation is believed to play a key role in the remodeling of the immune system at older age, with evidence pointing to an inability to fine-control systemic inflammation, which seems to be a marker of unsuccessful aging... This reshaping of cytokine expression pattern, with a progressive tendency toward a pro-inflammatory phenotype has been called 'inflamm-aging.'
Why this rating
This is a review paper citing multiple primary studies across various disease models; high quality of evidence for the general concept, though specific interventions are often pre-clinical.

- Senescent cells contribute to aging and age-related diseases through the Senescence-Associated Secretory Phenotype (SASP), which promotes a pro-inflammatory milieu.Good
- Upregulating autophagy through lifestyle interventions (exercise, caloric restriction) or pharmacological agents (metformin, AMPK activators) can improve cellular housekeeping and potentially delay age-related diseases.Moderate
