Antioxidants are substances that help prevent or delay cell damage, which is why they have been heavily studied for their potential to prevent diseases such as cancer, heart disease, and Alzheimer’s disease.
The body produces its own antioxidants, but we can also obtain them through our diet or by taking supplements. Foods that are high in antioxidants include fruits, vegetables, nuts, and whole grains. Antioxidant supplements, on the other hand, typically contain vitamins A, C, and E, as well as other compounds like beta-carotene and selenium.
While diets high in antioxidants have been found to be healthy, research has not yet shown that antioxidant supplements are beneficial in preventing diseases. In fact, some studies have even suggested that taking antioxidant supplements can be harmful in certain situations.
For example, a study published in the New England Journal of Medicine found that smokers who took beta-carotene supplements had a higher risk of developing lung cancer than those who did not take the supplements. Another study published in the Journal of the American Medical Association found that vitamin E supplements did not reduce the risk of heart disease and may even increase the risk of heart failure.
So, while it’s important to consume a diet rich in fruits and vegetables to obtain natural antioxidants, taking supplements may not be the best way to obtain these important compounds. Instead, focusing on a healthy, balanced diet that includes a variety of fruits, vegetables, and whole grains is the best way to support overall health and well-being.
