Antioxidants

Antioxidants are molecules that help protect the body from damage caused by free radicals—unstable atoms that can cause oxidative stress, leading to cell damage and contributing to aging and various diseases such as cancer, heart disease, and neurodegenerative disorders.

Free radicals are generated naturally during metabolic processes, but their levels can increase due to factors like pollution, smoking, radiation, and poor diet. Antioxidants neutralize free radicals by donating electrons, stabilizing them and preventing damage to cells, proteins, and DNA. They are naturally found in many foods, particularly fruits and vegetables, and include a variety of compounds such as vitamins, minerals, and plant-derived polyphenols.

Common types of antioxidants are following substances. Vitamin C – a powerful water-soluble antioxidant found in citrus fruits, berries, and green vegetables. It supports the immune system and aids in collagen production. Vitamin E – a fat-soluble antioxidant found in nuts, seeds, and leafy greens. It protects cell membranes from oxidative damage.

Beta-carotene – a precursor to vitamin A, found in colorful fruits and vegetables like carrots, sweet potatoes, and spinach. Selenium – a mineral with antioxidant properties, found in foods such as Brazil nuts, fish, and whole grains. Flavonoids – plant compounds found in a variety of fruits, vegetables, and beverages like tea and red wine, known for their anti-inflammatory and antioxidant effects. Antioxidants are also available in supplement form, providing concentrated doses of these beneficial compounds. Popular supplements include: vitamin C and E supplements for boosting overall antioxidant defense; coenzyme Q10 (CoQ10) – a compound naturally produced by the body that plays a key role in energy production and has antioxidant properties; curcumin – the active compound in turmeric, known for its strong anti-inflammatory and antioxidant effects; resveratrol – a compound found in grapes and berries, often taken as a supplement for its potential to protect against aging and inflammation.

While antioxidants play a crucial role in maintaining health, it’s important to balance them with a varied diet rich in natural food sources to ensure optimal benefits.
