What are antioxidants?

Antioxidants are compounds that play a crucial role in maintaining the balance of oxidative processes in our bodies. To understand antioxidants, it's essential to first comprehend oxidation and its potential harm to our cells. Oxidation is a chemical process in which a substance reacts with oxygen, leading to the loss of electrons and often resulting in changes in colour, texture, or chemical composition. It is a natural chemical process that occurs in our bodies as a result of various factors, including metabolic reactions, exposure to environmental pollutants, and lifestyle choices such as smoking and poor diet. During oxidation, unstable molecules called free radicals are formed, which have unpaired electrons in their outer shells, making them highly reactive.

Free radicals, due to their unstable nature, seek to stabilize themselves by taking electrons from other molecules in the body. This process can lead to a chain reaction, causing damage to cellular components such as DNA, proteins, and lipids. This oxidative damage is associated with a wide range of health issues, including chronic diseases like cardiovascular disease, cancer, and neurodegenerative disorders.

Antioxidants, on the other hand, act as protectors against this oxidative damage. They have the ability to donate an electron to stabilize free radicals without becoming unstable themselves. This neutralizes the harmful effects of free radicals and breaks the chain reaction of oxidative damage. Scientific research supports the importance of antioxidants in maintaining health and preventing chronic diseases.

The Importance of Antioxidants for Overall Health 

Antioxidants play a vital role in promoting overall health and well-being by protecting our cells from the damaging effects of oxidative stress. Oxidative stress occurs when there is an imbalance between the production of reactive oxygen species (ROS) or free radicals and the body's ability to detoxify or repair the resulting damage. This oxidative damage is implicated in numerous health conditions, including cardiovascular diseases, neurodegenerative disorders, cancer, and aging.

The importance of antioxidants lies in their ability to neutralize free radicals and prevent or minimize the damage caused by oxidative stress. Antioxidants accomplish this by donating an electron to the free radicals, thereby stabilizing them and reducing their reactivity. This process interrupts the chain reaction of oxidative damage and helps protect cellular components such as DNA, proteins, and lipids.

Research has shown the profound impact of antioxidants on overall health and well-being. For instance, a study published in the Journal of the American College of Cardiology demonstrated that increased dietary intake of antioxidants was associated with a lower risk of cardiovascular disease (Knekt et al., 2002). Another study published in the Journal of Clinical Oncology highlighted the potential role of antioxidants in reducing the risk of cancer development and progression (Block et al., 2007).

Understanding Free Radicals

Free radicals are highly reactive molecules that possess unpaired electrons in their outer shells. These unstable molecules are constantly formed in our bodies as byproducts of normal metabolic processes or due to external factors such as exposure to environmental pollutants, radiation, tobacco smoke, and certain medications. Free radicals can also be generated as part of the immune response to fight off pathogens.

The unpaired electrons of free radicals make them highly reactive and prone to steal electrons from other molecules in an attempt to stabilize themselves. This process sets off a chain reaction, as the molecule that loses an electron becomes a free radical itself, leading to a cascade of oxidative damage in the body.

The harmful effects of free radicals on the body are primarily attributed to oxidative stress. Oxidative stress occurs when the balance between the production of free radicals and the body's antioxidant defences is disrupted, resulting in an excess of free radicals. The accumulation of oxidative damage over time can contribute to the development and progression of various health conditions, including cardiovascular diseases, neurodegenerative disorders, cancer, and aging.

The damaging effects of free radicals extend to different cellular components. For instance, free radicals can attack and damage DNA, leading to mutations that may contribute to the development of cancer. They can also oxidize lipids, causing lipid peroxidation, which can damage cell membranes and disrupt their integrity. Additionally, free radicals can modify proteins, altering their structure and function and impairing their normal cellular processes.

The human body possesses its own defence mechanisms against free radicals, including antioxidant enzymes and molecules. Antioxidants work by neutralizing free radicals, donating an electron to stabilize them without becoming unstable themselves. Antioxidants can be endogenous, produced by the body, or obtained from external sources such as diet and supplementation.

Free radicals, with their unpaired electrons, can have detrimental effects on the body. These highly reactive molecules can initiate a chain reaction of oxidative damage, leading to cellular dysfunction and increased susceptibility to various health conditions.

  1. Aging: Free radicals play a significant role in the aging process. As we age, our body's natural antioxidant defences may weaken, while the production of free radicals increases. This imbalance can lead to oxidative stress, which can accelerate aging at the cellular level. Oxidative damage accumulates over time, causing wear and tear on cells, tissues, and organs, and contributing to the physical and functional decline associated with aging.

  2. Chronic Diseases: Free radicals have been implicated in the development and progression of chronic diseases. Oxidative stress resulting from an imbalance between free radicals and antioxidants can damage cellular structures, including proteins, lipids, and DNA. This damage can disrupt normal cellular functions and contribute to the pathogenesis of various conditions, such as cardiovascular diseases, neurodegenerative disorders (e.g., Alzheimer's disease, Parkinson's disease), cancer, diabetes, and inflammatory diseases.
    • Cardiovascular Diseases: Free radicals can oxidize low-density lipoprotein (LDL) cholesterol, leading to the formation of plaque in arteries and increasing the risk of heart disease and stroke.
    • Neurodegenerative Disorders: Oxidative damage caused by free radicals can contribute to the degeneration of nerve cells in the brain, leading to cognitive decline and neurodegenerative diseases.
    • Cancer: Free radicals can promote DNA damage and mutations, potentially leading to the development of cancerous cells and tumour growth.
    • Diabetes: Oxidative stress can impair insulin signalling and contribute to insulin resistance, a key factor in the development of type 2 diabetes.
    • Inflammatory Diseases: Free radicals can trigger and sustain inflammation, leading to chronic inflammatory diseases, such as rheumatoid arthritis and inflammatory bowel disease.

  3. Oxidative Stress: Free radicals are the primary contributors to oxidative stress. Oxidative stress occurs when the production of free radicals exceeds the body's antioxidant capacity to neutralize them. This imbalance can result in cellular damage, inflammation, and disruption of normal physiological processes. Oxidative stress has been linked to numerous health problems, including cardiovascular diseases, neurodegenerative disorders, diabetes, metabolic syndrome, and even psychological conditions such as depression and anxiety.

The Role of Antioxidants

Antioxidants play a vital role in maintaining cellular health by neutralizing free radicals and protecting cells from oxidative damage. 

There are several mechanisms through which antioxidants protect cells:

  1. Electron Donation: Antioxidants have the ability to donate an electron to free radicals without becoming unstable themselves. By providing a stable electron, antioxidants effectively neutralize free radicals and break the chain reaction of oxidative damage.

  2. Free Radical Scavenging: Antioxidants act as scavengers, seeking out and neutralizing free radicals throughout the body. They can intercept free radicals before they can cause damage to cellular structures, including DNA, proteins, and lipids.

  3. Regeneration of Other Antioxidants: Some antioxidants have the ability to regenerate other antioxidants in the body. For example, vitamin E can regenerate vitamin C, which plays a crucial role in neutralizing free radicals in the watery compartments of cells. This regenerative capacity ensures a continuous supply of antioxidants to combat free radicals effectively.

  4. Protection of Cellular Components: Antioxidants can directly protect important cellular components from oxidative damage. For instance, they can stabilize and protect DNA from mutations caused by free radicals, preserving the integrity of genetic information. Antioxidants also help maintain the structure and function of proteins and lipids within cell membranes, preventing disruptions in cellular processes.
