Antiox­i­dants are com­pounds that help pro­tect cells and oth­er mol­e­cules in the body from dam­age caused by harm­ful mol­e­cules called free rad­i­cals. Free rad­i­cals are unsta­ble mol­e­cules that are gen­er­at­ed as nat­ur­al byprod­ucts of var­i­ous meta­bol­ic process­es, as well as from expo­sure to envi­ron­men­tal fac­tors such as pol­lu­tion, UV radi­a­tion, and tobac­co smoke. These free rad­i­cals can dam­age DNA, pro­teins, lipids (fats), and oth­er cel­lu­lar com­po­nents, which can con­tribute to oxida­tive stress and var­i­ous dis­eases.

Antiox­i­dants neu­tral­ize free rad­i­cals by donat­ing elec­trons, which sta­bi­lizes the free rad­i­cals and pre­vents them from caus­ing fur­ther dam­age. Antiox­i­dants play a cru­cial role in main­tain­ing cel­lu­lar health and reduc­ing the risk of chron­ic dis­eases asso­ci­at­ed with oxida­tive stress, such as heart dis­ease, can­cer, and neu­rode­gen­er­a­tive dis­or­ders.

There are sev­er­al types of antiox­i­dants, includ­ing:

• Vit­a­mins: Cer­tain vit­a­mins have antiox­i­dant prop­er­ties. For exam­ple:
  • Vit­a­min C (ascor­bic acid): Found in cit­rus fruits, berries, and veg­eta­bles. It helps pro­tect cells and sup­ports the immune sys­tem.
  • Vit­a­min E: Found in nuts, seeds, and veg­etable oils. It pro­tects cell mem­branes from oxida­tive dam­age.
  • Vit­a­min A (beta-carotene): Found in orange and yel­low fruits and veg­eta­bles. It sup­ports vision, immune func­tion, and skin health.
• Min­er­als: Cer­tain min­er­als act as antiox­i­dants or are involved in antiox­i­dant enzyme sys­tems. For exam­ple:
  • Sele­ni­um: Found in nuts, seeds, seafood, and whole grains. It’s a com­po­nent of antiox­i­dant enzymes.
  • Zinc: Found in meat, dairy, and legumes. It’s essen­tial for antiox­i­dant enzyme func­tion.
• Phy­to­chem­i­cals: These are nat­u­ral­ly occur­ring com­pounds found in plants that have antiox­i­dant prop­er­ties. Some exam­ples include:
  • Flavonoids: Found in fruits, veg­eta­bles, tea, and cocoa. They have anti-inflam­ma­to­ry and antiox­i­dant effects.
  • Carotenoids: Found in col­or­ful fruits and veg­eta­bles. Beta-carotene is a well-known carotenoid with antiox­i­dant prop­er­ties.
• Enzymes: The body pro­duces its own antiox­i­dant enzymes that neu­tral­ize free rad­i­cals. Exam­ples include super­ox­ide dis­mu­tase (SOD), cata­lase, and glu­tathione per­ox­i­dase.
• Coen­zyme Q10 (CoQ10): This com­pound is involved in ener­gy pro­duc­tion with­in cells and also has antiox­i­dant prop­er­ties. It’s found in meat, fish, and whole grains.
• Mela­tonin: This hor­mone is involved in reg­u­lat­ing sleep-wake cycles and has antiox­i­dant effects. It’s nat­u­ral­ly pro­duced by the body and is also avail­able as a sup­ple­ment.
• Lipoic Acid: Found in small amounts in foods like spinach, broc­coli, and organ meats. It has both water- and fat-sol­u­ble antiox­i­dant prop­er­ties.

Antiox­i­dants work togeth­er in a com­plex sys­tem, and hav­ing a vari­ety of them in your diet is ben­e­fi­cial for over­all health. Obtain­ing antiox­i­dants from a bal­anced and diverse diet that includes a wide range of fruits, veg­eta­bles, nuts, seeds, and whole grains is rec­om­mend­ed for opti­mal health and well-being.
