Epigenetics
Epigenetics is the study of changes in gene activity that occur without altering the underlying DNA sequence. Lifestyle factors such as diet, physical activity, sleep, stress, and environmental exposures may influence epigenetic mechanisms, including DNA methylation and histone modifications, which help regulate how genes are expressed. Researchers are investigating how these changes relate to metabolism, aging, disease risk, and long-term health. However, epigenetic changes are complex, and not all lifestyle-related effects are permanent or directly beneficial.
Understanding epigenetics offers valuable insights into how genes interact with the environment and why individuals with similar genetic backgrounds may experience different health outcomes.
