  • Specific dietary components may affect biological ageing through processes like nutrient sensing and inflammation modulation.
  • Culturally tailored dietary interventions could improve adoption of healthy eating practices.
  • Barriers such as food insecurity and limited access to healthy options are associated with poorer health outcomes, especially in low-income and rural areas.
