What is antioxidant activity?

A. Physical activity that increases the heart rate and breathing rate for a long period of time

B. Physical activity that focuses on improving flexibility and balance

C. Physical activity that involves brief bursts of intense effort without relying on oxygen for energy

D. Physical activity that promotes relaxation and stress reduction

Key Points

• Antioxidant activity refers to the process where antioxidants neutralize free radicals, which are unstable molecules that can cause cellular damage.
• Free radicals are produced through normal metabolic processes and external factors like pollution and radiation.
• Antioxidants donate electrons to free radicals, stabilizing them and preventing oxidative stress, which can lead to chronic diseases.
• Common antioxidants include vitamins C and E, selenium, and beta-carotene, which are found in various foods such as fruits, vegetables, and nuts.

Additional Information

• Physical Activity:
  • Physical activity refers to any movement of the body that requires energy expenditure.
  • Different types of physical activities include aerobic exercises, strength training, flexibility exercises, and balance exercises.
  • Engaging in regular physical activity is crucial for maintaining overall health and preventing chronic diseases.
  • The World Health Organization recommends at least 150 minutes of moderate-intensity aerobic physical activity throughout the week for adults.
• Oxidative Stress:
  • Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body.
  • It can lead to cellular damage, contributing to aging and various diseases such as cancer, cardiovascular diseases, and neurodegenerative disorders.
  • Preventing oxidative stress involves consuming a diet rich in antioxidants, exercising, and avoiding exposure to harmful environmental factors.
• Free Radicals:
  • Free radicals are unstable molecules that can react with other molecules in the body, causing cellular damage.
  • They are produced naturally during metabolic processes but can also be introduced through external sources like pollution and radiation.
  • Antioxidants help neutralize free radicals, preventing them from causing harm to the body's cells.
