Oxidative Stress
Definition
Oxidative stress is a condition that occurs when there is an imbalance between free radicals and antioxidants in the body, leading to potential damage to cells and tissues.
Scientific / Technical Definition
Oxidative stress refers to a state in which the production of reactive oxygen species (ROS) and free radicals exceeds the body's ability to neutralize and eliminate them through its antioxidant defense mechanisms, potentially causing cellular and DNA damage, lipid peroxidation, and protein modification.
Benefits
- Understanding oxidative stress can help in developing strategies to prevent or mitigate chronic diseases.
- Managing oxidative stress through diet and lifestyle can support overall health and well-being.
Examples
- Broccoli, which contains antioxidants that help combat oxidative stress.
- Green tea, known for its high levels of polyphenols that reduce oxidative stress.
- Berries, like blueberries and strawberries, which are rich in antioxidants.
Additional Information
- Effects: Oxidative stress has been linked to several chronic conditions, including cardiovascular diseases, neurodegenerative disorders, and cancer due to its potential to damage cells and DNA over time.
