Antioxidants are compounds that are found in various foods, plants and supplements. These compounds help to prevent or delay damage to cells caused by free radicals, which are highly reactive molecules that can cause oxidative stress and damage DNA, proteins, and lipids in the body. This article will explore the role of antioxidants in health and disease prevention and the latest research on their effectiveness. Oxidative stress is a contributing factor to several chronic diseases, including cancer, cardiovascular disease, diabetes, neurodegenerative diseases, and other age-related diseases. Free radicals can cause damage to cells, leading to inflammation and cellular dysfunction, which can ultimately result in disease. Antioxidants neutralize free radicals and prevent cellular damage, potentially reducing the risk of developing chronic diseases. Studies suggest that antioxidants play a crucial role in preserving overall health and preventing several diseases. For example, research shows that consuming antioxidant-rich foods like fruits, vegetables, and nuts can lower the risk of developing cancer, cardiovascular disease, and type 2 diabetes. Antioxidant-rich foods also improve cognitive function, improve vision, improve immune function, and protect against neurodegeneration.

The most well-known antioxidants are vitamins A, C and E, and the minerals selenium and zinc. These antioxidants are essential for overall health [1]. Vitamin C, in particular, is a water-soluble vitamin that is found in several fruits and vegetables, including oranges, strawberries, bell peppers, and broccoli. Vitamin C helps to protect the body's cells from oxidative stress and prevents the formation of cancer-causing compounds [2]. Vitamin E is a potent antioxidant that is found in nuts, seeds, and leafy green vegetables. Vitamin E protects cell membranes, which help to maintain the structure and function of cells. Selenium is a mineral that acts as an antioxidant and is found in foods like Brazil nuts, sardines, and tuna fish [3]. Selenium has been linked to a reduced risk of cancer and improved immune function. The role of antioxidants in disease prevention is a topic of ongoing research, and a significant amount of attention has been focused on whether antioxidants can effectively prevent or treat chronic diseases. The findings of some studies have suggested that while antioxidants can certainly play a role in disease prevention, they may not be as effective in treating established health conditions [4,5]. Some studies have suggested that high doses of certain antioxidants (such as vitamin E) may increase the risk of certain health problems. Therefore, it is important to consume antioxidants in the form of whole foods rather than relying on supplements to meet your daily needs. Antioxidants play a crucial role in maintaining overall health and preventing chronic diseases. They protect cells from oxidative stress caused by free radicals and are found in many fruits, vegetables, nuts, and seeds. Eating a diet rich in antioxidants can have numerous benefits, including improved cognitive function, stronger immune system, and reduced risk of cancer and heart disease. Remember to practice moderation when it comes to antioxidant supplements and aim to meet your daily requirements through whole foods. By doing so, you can reap the full benefits of these powerful compounds and support your long-term health. Antioxidants provide several benefits to our health, including protecting our cells from oxidative stress and reducing the risk of chronic diseases [6,7]. Some specific advantages of antioxidants include:

Reducing the risk of cancer

Antioxidants can neutralize free radicals, which can cause damage to our DNA and lead to the development of cancer. Research has shown that consuming a diet rich in antioxidants may help to reduce the risk of several types of cancer, including lung, colon, prostate, and breast cancer [8].

Protecting cardiovascular health

Free radicals can also damage our blood vessels and contribute to the development of heart disease. Antioxidants can reduce inflammation and protect the cells in our blood vessels, leading to improved cardiovascular health.

Boosting immune function

Antioxidants help to protect our immune cells from damage caused by free radicals, which can improve their ability to fight off infections and diseases [9].

Supporting brain health

Antioxidants can cross the blood-brain barrier and protect our brain cells from oxidative stress, potentially reducing the risk of neurodegenerative diseases like Alzheimer's and Parkinson's. Improving skin health: Antioxidants can protect our skin from damage caused by UV radiation and pollution, which can contribute to premature aging and skin cancer. Antioxidants like vitamins C and E and beta-carotene can also boost collagen production and improve skin elasticity. Antioxidants offer several advantages when it comes to supporting our overall health and reducing the risk of chronic diseases. By consuming a diet rich in whole foods that contain antioxidants, we can harness the power of these compounds and support our long-term health [10].
