However, some research suggests that ketogenic diets may increase the production of endogenous antioxidants like glutathione.

While there is no “too little” of antioxidants, as the body has its own defense mechanisms, optimal levels are essential for maintaining health. Excessive intake of certain antioxidant supplements, however, can have adverse effects.

There are no direct synonyms for “antioxidant,” but related terms include “free radical scavenger” and “oxidative stress inhibitor.”

The concept of antioxidants gained popularity in the late 20th century, with numerous studies highlighting their potential health benefits. However, the use of antioxidant supplements remains controversial, with some research suggesting limited or no benefit, while others raise concerns about potential harm.

Summary and Conclusion

Antioxidants are the unsung heroes of our cellular world. They work tirelessly to protect our cells from oxidative damage, safeguarding our health and well-being. By embracing a diet rich in vegetables, and other antioxidant-rich foods, we can support our body’s natural defense mechanisms and potentially reduce the risk of chronic diseases.
