The Science Behind Antioxidants: How They Keep Your Body Healthy

We often hear about the importance of antioxidants for maintaining a healthy diet, but what exactly are antioxidants and how do they benefit the body? In this article, we’ll take a closer look at the science behind antioxidants and their many health benefits.

What are Antioxidants?

Antioxidants are substances that protect cells in your body from damage caused by free radicals. Free radicals are unstable molecules that are produced in the body during normal metabolic processes, as well as by exposure to environmental factors like pollution, radiation and cigarette smoke. When left unchecked, free radicals can damage cells and contribute to the aging process and the development of diseases like cancer, heart disease and Alzheimer’s disease.

Types of Antioxidants

There are many types of antioxidants, but some of the most well-known include:

  • Vitamin C – found in citrus fruits, strawberries, kiwi and broccoli
  • Vitamin E – found in nuts, seeds, vegetable oils and leafy greens
  • Beta-carotene – found in yellow and orange fruits and vegetables
  • Selenium – found in nuts, meat and seafood
  • Flavonoids – found in tea, berries, and dark chocolate

Health Benefits of Antioxidants

Antioxidants have many health benefits, including:

  • Slowing down the aging process by protecting cells from damage caused by free radicals.
  • Reducing the risk of cancer by protecting cells from DNA damage that can lead to cancer.
  • Lowering the risk of heart disease by reducing inflammation and improving cholesterol levels.
  • Improving brain function and reducing the risk of cognitive decline.
  • Protecting skin from damage caused by UV rays.

How to Get More Antioxidants

The best way to get more antioxidants is to eat a diet rich in fruits, vegetables, whole grains, nuts and seeds. Aim for a variety of colorful fruits and vegetables, as the different colors indicate different types of antioxidants.

Supplements can also be a good source of antioxidants, but it’s always best to get your nutrients from whole foods whenever possible. Talk to your doctor or a registered dietitian before starting any new supplements.

The Bottom Line

Antioxidants are an important part of a healthy diet and play a key role in protecting your body from the damaging effects of free radicals. By eating a variety of nutrient-rich foods, you can ensure that you’re getting plenty of antioxidants to keep your body healthy and functioning at its best.
