Introduction:
Antioxidants are the natural substances found in the food we eat. They play an essential role in protecting our body from harmful free radicals. Free radicals are unstable molecules that can damage our cells and tissues, and antioxidants neutralize them. In this article, we will explore the science behind how antioxidants protect our body.
1. What are antioxidants?
Antioxidants are natural substances found in our food, such as fruits, vegetables, nuts, and seeds. They are molecules that can prevent or slow down the damage to our cells caused by free radicals. Some of the most common antioxidants include vitamin C, vitamin E, beta-carotene, and selenium.
2. How do free radicals damage our cells?
Free radicals are unstable molecules that have an unpaired electron. To become stable, they steal electrons from other molecules in our body, causing damage to our cells and tissues. This process is known as oxidative stress. Oxidative stress has been linked to various diseases such as cancer, heart disease, and Alzheimer’s disease.
3. How do antioxidants neutralize free radicals?
Antioxidants neutralize free radicals by donating an electron to them, which stabilizes them and prevents them from causing further damage to our cells. Antioxidants can also repair the damage caused by free radicals.
4. How do antioxidants work in our body?
Antioxidants work in different ways in our body. Some antioxidants such as vitamin C and glutathione work inside our cells, while others such as vitamin E and beta-carotene work in the lipid or fatty part of our cells. Antioxidants also work together in a synergistic way, making them more effective in protecting our cells from oxidative stress.
5. What are the sources of antioxidants?
Antioxidants are found in a variety of foods, especially fruits and vegetables. Some of the best sources of antioxidants include berries, citrus fruits, leafy greens, nuts, seeds, and whole grains. It is essential to include a variety of antioxidant-rich foods in our diet to ensure we get enough of these essential nutrients.
6. How much antioxidants should we consume daily?
There is no set recommended daily intake of antioxidants. However, it is recommended to consume a variety of antioxidant-rich foods daily to ensure we get enough of these essential nutrients.
Conclusion:
In conclusion, antioxidants play a crucial role in protecting our body from oxidative stress caused by free radicals. They work by neutralizing free radicals and repairing the damage caused by them. It is essential to include a variety of antioxidant-rich foods in our diet to ensure we get enough of these essential nutrients. So, make sure to load up your plate with colorful fruits and vegetables to keep your body healthy and protected.
