Free radicals are unstable and highly reactive molecules that can cause damage to cells, proteins, and DNA through oxidation. They can be naturally produced during the body’s normal metabolic processes or introduced from external sources such as pollution, radiation, and smoking.
The damage caused by free radicals can lead to various health issues including cancer, heart disease, diabetes, and neurodegenerative diseases like Alzheimer’s disease.

Understanding Free Radicals
|
Definition of free radicals: Free radicals are unstable and highly reactive molecules that are naturally produced during the body’s normal metabolic processes or can be introduced from external sources such as pollution, radiation, and smoking. They are molecules with one or more unpaired electrons, making them highly reactive and prone to oxidation. |
|
Characteristics of free radicals: Free radicals can damage the body by stealing electrons from other molecules in a process called oxidation. This can cause damage to cells, proteins, and DNA. When free radicals react with DNA, it can cause mutations that may lead to the development of cancer. When they react with proteins, it can cause changes in their structure and function, leading to impaired cellular activity. Free radicals can also contribute to the development of many chronic diseases such as heart disease, diabetes, and neurodegenerative diseases like Alzheimer’s disease. This is because they can cause inflammation, damage blood vessels, and impair cellular processes that are essential for normal bodily functions. |

Impact Of Free Radicals On The Body
Free radicals are unstable and highly reactive molecules that can cause damage to cells, proteins, and DNA by stealing electrons from other molecules in a process called oxidation. This can lead to mutations, impaired cellular activity, and the development of chronic diseases like cancer, heart disease, and neurodegenerative diseases.
It is important to understand how long free radicals last in order to mitigate their impact on the body.

| Link between free radicals and the development of cancer |
| Research has shown that when free radicals react with DNA, it can cause mutations that may lead to the development of cancer. Free radicals are highly reactive molecules that have the ability to steal electrons from other molecules. This process, known as oxidation, can result in changes in DNA structure, which can lead to genetic mutations. These mutations can disrupt the normal functioning of cells and may eventually contribute to the development of cancer. It is important to minimize exposure to free radicals and incorporate a diet rich in antioxidants to help neutralize their harmful effects. |
| Contribution of free radicals to chronic diseases |
| Free radicals have been implicated in the development of many chronic diseases such as heart disease, diabetes, and neurodegenerative diseases like Alzheimer’s disease. The oxidative damage caused by free radicals can result in inflammation, damage to blood vessels, and impaired cellular processes. Inflammation plays a key role in the development of chronic diseases, and free radicals can initiate and perpetuate this inflammatory response. Additionally, free radicals can damage the delicate lining of blood vessels, leading to the formation of plaque and the narrowing of arteries. This can increase the risk of heart disease and stroke. Furthermore, the oxidative stress caused by free radicals can disrupt cellular processes that are essential for normal functioning, potentially contributing to the development of neurodegenerative diseases. Reducing exposure to free radicals and adopting a healthy lifestyle that includes a balanced diet and regular exercise can help mitigate the risk of these chronic diseases. |
Conclusion
To wrap up, free radicals are unstable and highly reactive molecules that can cause significant damage to our bodies. This damage can lead to various health issues, including the development of chronic diseases like cancer and heart disease. It is important to understand the sources of free radicals, such as pollution and smoking, and take steps to minimize their impact.
By incorporating a balanced and antioxidant-rich diet, practicing regular exercise, and avoiding harmful environmental exposures, we can help reduce the lasting effects of free radicals and maintain overall health and well-being.
