Oxidative Stress

Definition

Oxidative stress is an imbalance between free radicals and antioxidants in the body, which can lead to cell and tissue damage.

Scientific / Technical Definition

Oxidative stress refers to a disparity between the production of reactive oxygen species (free radicals) and antioxidant defenses. This can lead to molecular and tissue damage, contributing to a range of diseases and aging processes.

Benefits

• Understanding oxidative stress can help in managing and preventing conditions related to chronic inflammation.
• Recognizing signs of oxidative stress can aid in dietary adjustments to include more antioxidants.

Examples

• Eating a diet rich in fruits and vegetables can help reduce oxidative stress by providing antioxidants.
• Supplementing with vitamins C and E may assist in reducing oxidative stress.

Additional Information

• effects: Oxidative stress is implicated in the pathogenesis of various diseases, such as atherosclerosis, hypertension, diabetes, and neurodegenerative disorders.
