What is Oxidative Stress?

Oxidative stress is a physiological condition that occurs when there is an imbalance between free radicals (reactive molecules with unpaired electrons) and the body’s ability to neutralize them with antioxidants. Free radicals are highly reactive and can damage cells, proteins, and DNA in the body, leading to various health problems and contributing to the aging process.

The body normally produces free radicals as byproducts of metabolic processes and in response to environmental factors such as pollution, radiation, and UV rays. When the production of free radicals exceeds the body’s capacity to neutralize them, oxidative stress can occur. This imbalance can result from various factors, including:

Poor diet: Consuming a diet low in antioxidants and high in processed or unhealthy foods can increase oxidative stress.

Environmental factors: Exposure to pollution, toxins, and radiation can generate free radicals in the body.

Lifestyle choices: Smoking, excessive alcohol consumption, and lack of physical activity can contribute to oxidative stress.

Inflammation: Chronic inflammation can also produce free radicals and exacerbate oxidative stress.

Oxidative stress has been implicated in various health conditions, including:

Aging
Cancer
Cardiovascular diseases
Neurodegenerative diseases (such as Alzheimer’s and Parkinson’s)
Diabetes
Inflammatory conditions
Autoimmune diseases
Eye diseases (like age-related macular degeneration)
To combat oxidative stress and its potential harm, it’s essential to maintain a healthy lifestyle with a balanced diet rich in antioxidants (found in fruits, vegetables, and whole grains), regular physical activity, and other healthy habits. Additionally, some people may take antioxidant supplements, but it’s important to consult a healthcare professional before doing so, as excessive antioxidant intake can have adverse effects.
