What are antioxidants?

These are naturally occurring chemicals that fight a process known as oxidative stress in your cells and are thought to boost overall health. The main sources are plant-based foods, including fruits and vegetables. However, they can also be found in man-made substances, such as dietary supplements.

Examples of antioxidants include:

  • Beta-carotene
  • Lutein
  • Lycopene
  • Selenium
  • Manganese
  • Vitamin A
  • Vitamin C
  • Vitamin E

Plant nutrients and chemicals such as phenols, polyphenols, flavonoids and phytoestrogens are also antioxidants. Each antioxidant has unique properties and performs a different function. So, it is a misconception that antioxidants are interchangeable with one another. For this, it is necessary to have a range of different foods.

Prospective studies have shown that a higher intake of antioxidant-rich foods effectively contributes to reducing the risk of chronic oxidative stress-related diseases. Cardiovascular disease, cancer, and death from all causes. At the same time, there is a large body of evidence that eating fruits, vegetables, and whole grains provides protection against many of the injuries of aging.

In this article, we will look at some nutrients with antioxidant activity and the foods in which they are found.:


It is an important dietary compound associated with various health benefits. It is an antioxidant that belongs to a group of color pigments called carotenoids.

Various studies have shown that increased blood levels of selenium are associated with increased immune function. Research suggests that it may help reduce the production of oxidized LDL and, therefore, protect against heart disease risk as well as cancer, particularly of the lung, colon and prostate.

Where to find:

Brazil nuts, grains, garlic, eggs, soybeans, seafood, red meat and liver.

Omega-3 and Omega-6 fatty acids

Omega-3s are extremely powerful antioxidants that help remove toxins from the body and protect cells and tissues from oxidative stress, allowing them to function optimally. Both essential omega-6 and omega-3 fatty acids are beneficial in the prevention or treatment of several cardiovascular, neurological, dermatologic, and psychiatric disorders.

Flaxseed, salmon, tuna, sardines, walnuts, vegetable oil, almonds, chicken
