Free radicals play a dual role in our body that can be both beneficial and harmful. Our body purposely creates free radicals to neutralize viruses and bacteria. These free radicals are unstable, highly reactive molecules that have one or more unpaired electrons. To gain stability, they attack stable molecules, triggering a chain reaction that damages healthy cells. When free radicals accumulate, they may cause a state known as oxidative stress. This may damage your DNA and other important structures in your cells. Sadly, chronic oxidative stress can increase your risk of chronic diseases such as heart disease. Aging itself is not a disease; rather, it is a normal process of any living species in the world.Fortunately, eating a diet rich in antioxidants can help increase your blood antioxidant levels to fight oxidative stress and reduce the risk of diseases. Natural antioxidants can be found in fruits and vegetables and are divided into three groups: vitamins, carotenoids and phenolic compounds.

The Main Benefits of Antioxidants

  1. Correct signs of age.

By neutralizing free radicals, antioxidants help limit not just the internal deterioration caused by aging, but also the outward physical effects. By scavenging free radicals, antioxidants canreduce the signs of aging by minimizing wrinkles, preserving the texture of the skin, and even reducing your susceptibility to sun damage.

  1. Combat Heart Disease

Antioxidants found in your morning coffee or tea, known as polyphenol antioxidants, help prevent heart disease. They work to prevent the oxidation of fat and thereby limit the internal inflammation that may increase risk of heart disease and diabetes.

  1. Fight Neurological and Mood Disorders

Thereis a link between free radicals and mood disorders like anxiety and depression as well as complex neurological diseases such as Parkinson’s and Alzheimer’s. Antioxidants work to combat neuroinflammation caused by free radical damage, which is thought to be a precursor to neurodegenerative diseases.

  1. Boost Body’s Natural Defenses

Free radicals are naturally formed by the body during exercise and through various energy processes in the body. At the same time, your body releases enzymes to keep these free radicals under control. Many antioxidants work by quenching free radicals need for an extra electron, thereby neutralizing these potentially harmful particles.

  1. Combat the Mental Effects of Aging

Antioxidants in berries, such as such as vitamins E and C, may help defray the effects of aging and prevent or even reverse memory loss. They do so by helping to improve brain cells ability to maintain long-term communication and establish strong connections.

  1. Improve Vision

Carotenoids, the pigments found in a number of fruits and vegetables. When consumed, these carotenoids form vitamin A in the body, which also has a protective effect. Vitamin A regulates the pigment produced by the retina, helping to protect your eyes from sun damage while maintaining the functionality of your low-light and color vision.
