Antioxidants are substances that help to neutralize oxidative damage in cells and tissues. Oxidative stress occurs when there is an imbalance between the formation of free radicals and the body’s ability to neutralize these harmful molecules. Free radicals are unstable atoms or molecules that are produced by natural metabolic processes, environmental conditions or even certain foods. They can damage cells, leading to various health problems, including inflammation, disease and premature ageing.
Antioxidants can be found both in food and in the body. The best-known antioxidants include vitamin C, vitamin E, beta-carotene, selenium and various secondary plant substances such as polyphenols and flavonoids. These compounds are found in abundance in fruit, vegetables, nuts and wholegrain products. Particularly powerful sources are berries, dark chocolate, green tea and broccoli.
Regular intake of antioxidant foods is associated with a variety of health benefits. Studies have shown that antioxidants can reduce the risk of chronic diseases such as heart disease, diabetes and certain types of cancer. They can also help to strengthen the immune system and slow down the ageing process.
A balanced diet rich in natural antioxidants is the best way to promote health and minimize the risk of oxidative stress. Therefore, it is recommended to eat a varied diet with a variety of colorful fruits and vegetables to ensure the best supply of antioxidants.
