Antioxidants are incredibly important for optimal health. They are natural molecules that help neutralise harmful free radicals in our bodies. Free radicals are potentially harmful substances that result from metabolism and the environment. They may lead to oxidative stress, which contributes to heart disease and other conditions. Antioxidants are mostly found in plant foods, but they are also present in some animal foods. A diet rich in antioxidants can be achieved by consuming a variety of colourful fruits, vegetables, legumes, nuts, seeds, herbs, spices, whole grains, and fatty fish.

Antioxidants are found in plant and animal foods, especially vegetables, fruits, and berries
Antioxidants are mostly found in plant foods, with some also present in animal foods. They are natural molecules that help neutralise harmful free radicals in our bodies. Free radicals are potentially harmful substances that result from metabolism and the environment. They may lead to oxidative stress, which contributes to heart disease and other conditions.
Plant-based antioxidants are a kind of phytonutrient, or plant-based nutrient. They are highly effective at low concentrations, and a variety of antioxidant compounds can be extracted from a single plant source. Plant-based antioxidants are also more practical for use in food processing. They are used extensively in the food industry to improve shelf life, colour, texture, and sensory properties.
Some common plant-based foods rich in antioxidants include berries, kale, grapes, beans, green tea, coffee, and dark chocolate. Berries, in particular, are known to have a very high antioxidant content. In fact, on average, plant foods have 64 times more antioxidant power than red meat, poultry, fish, dairy, and eggs.
Animal-based antioxidants are also beneficial, although they are found in lower quantities in animal foods. Meat products and fish contain antioxidants, but to a lesser extent than fruits and vegetables. Ox liver, for example, is one of the few animal foods that can beat lettuce in antioxidant content. Human breast milk is also known to be rich in antioxidants.

They help neutralise free radicals, which are harmful molecules that can damage DNA and cell membranes
Antioxidants are essential for optimal health and can be found in both animal and plant-based foods. They are particularly abundant in vegetables, fruits, and berries.
Antioxidants are important because they help neutralise free radicals, which are harmful molecules that can damage DNA and cell membranes. Free radicals are unstable atoms that result from metabolism and environmental factors, such as pollution, UV exposure, and cigarette smoke. They can lead to oxidative stress, which is linked to various diseases, including heart disease, cancer, arthritis, and Parkinson's disease.
Antioxidants, such as vitamins C and E, counteract the effects of free radicals by donating their own electrons. This helps to break the chain reaction of cell damage and protects the body from further harm.
While supplements are available, it is generally recommended to obtain antioxidants from whole foods. This is because studies have shown that whole foods reduce oxidative damage to a greater extent than supplements. Additionally, excessive intake of isolated antioxidants can have toxic effects, leading to a phenomenon known as the "antioxidant paradox."
To increase your antioxidant intake, aim to include a variety of colourful fruits and vegetables in your diet. Spices like turmeric and cinnamon, as well as nuts and seeds, are also excellent sources of antioxidants.

Antioxidants may lower the risk of chronic diseases, including cardiovascular disease and cancer
Antioxidants are substances that may protect cells from damage caused by unstable molecules called free radicals. Free radicals are the most common type of free radicals produced in living tissue and are also known as "reactive oxygen species" or "ROS". Antioxidants interact with and neutralise free radicals, preventing them from causing damage that may lead to cancer.
Laboratory and animal studies have shown that increased levels of antioxidants prevent the types of free radical damage associated with cancer development. Researchers have investigated whether dietary antioxidant supplements can help lower the risk of developing or dying from cancer in humans. Case-control and cohort studies have yielded mixed results. However, randomised controlled clinical trials may provide more reliable insights.
Cardiovascular disease (CVD) is the collective term for disorders affecting the heart and blood vessels, and it is the leading cause of death worldwide. Inflammation and oxidative stress are key risk factors for the onset and progression of CVD. Antioxidants may beneficially interfere with CVD by reducing the impact of ROS. Antioxidant vitamins and minerals, such as vitamins A, E, and C, and zinc, may slow the development and progression of CVD. Observational epidemiological studies suggest that higher levels of vitamin E are associated with a lower risk of CVD.
Overall, a sufficient intake of antioxidants through the diet or supplements may help lower the risk of chronic diseases, including cardiovascular disease and cancer, by reducing the damage caused by free radicals and oxidative stress.

A well-rounded diet with a variety of antioxidant-rich foods is better than supplements
Antioxidants are important molecules that prevent cell damage by neutralizing harmful free radicals, which are produced as the body processes food and reacts to the environment. Free radicals can lead to oxidative stress, which is linked to various diseases, including heart disease, cancer, arthritis, and Parkinson's disease.
A well-rounded diet with a variety of antioxidant-rich foods is the best way to ensure adequate antioxidant intake. Antioxidants are mostly found in plant-based foods, with vegetables, fruits, and berries being particularly good sources. For example, tomatoes contain the antioxidant lycopene, while kale is rich in lutein, and blueberries contain anthocyanins. Spices such as turmeric and ginger, as well as nuts and seeds, are also excellent sources of antioxidants.
While supplements can provide antioxidants, they may not always be effective or safe. Excessive intake of isolated antioxidants can have toxic effects and may even promote oxidative damage, a phenomenon known as the "antioxidant paradox." Studies have shown that antioxidant-rich whole foods reduce oxidative damage to a greater extent than supplements.
In addition, the synergistic effects of compounds in whole foods may contribute to their superior antioxidant activity compared to supplements. It is also important to note that some antioxidants, such as vitamin E, have been associated with an increased risk of cancer and stroke when taken in high doses as supplements.
Therefore, it is generally recommended to prioritize obtaining antioxidants from a diverse and colorful diet, rather than relying on supplements, to optimize health and reduce the risk of diseases associated with oxidative stress.

Excessive intake of isolated antioxidants can be toxic and may promote oxidative damage
Antioxidants are essential for optimal health. They are natural molecules that help neutralise harmful free radicals in our bodies. Free radicals are potentially harmful substances that result from metabolism and the environment. They may lead to oxidative stress, which contributes to heart disease and other conditions.
However, excessive intake of isolated antioxidants can be toxic and may promote oxidative damage. This phenomenon is termed the "antioxidant paradox". While antioxidants play a critical role in protecting cell membranes against oxidative damage, high doses of isolated antioxidants have been associated with detrimental effects. Studies indicate that consuming a variety of antioxidant-rich whole foods is more effective in reducing oxidative damage than taking high-dose supplements.
The body requires a balance between free radicals and antioxidants. When this equilibrium is disrupted, it can lead to oxidative stress, which can cause microscopic changes in the body. Prolonged oxidative stress increases the risk of negative health outcomes, such as cardiovascular disease, neurological diseases, and certain types of cancer.
To maintain a healthy balance, it is recommended to obtain antioxidants from a variety of food sources. Antioxidants are found in all whole foods of plant and animal origin, especially vegetables, fruits, and berries. Coffee, green tea, and dark chocolate are also good sources of antioxidants.
While supplements can provide a convenient way to increase antioxidant intake, high-dose antioxidant supplements are generally advised against by health professionals. This is because excessive intake of isolated antioxidants can have toxic effects, and the compounds in whole foods are believed to work synergistically to provide greater health benefits.
