The word “antioxidant” is a buzzword circling around in the health and wellness community and on social media, making claims that we all need them to stay healthy, young, beautiful, etc. Is “antioxidants” just a buzzword or are they really necessary for your health? How do we get them? And what types of antioxidants are there? 

We’re here to help with answers to your questions! Here’s a brief introduction to everything you need to know about antioxidants.


Free Radicals & Oxidative Stress

Free radicals are highly reactive particles that our bodies naturally produce; they can also come from the environment, such as radiation, pollution, tobacco smoke, and even the food we eat. These particles are unstable due to an incomplete number of electrons in their outer shells, making them highly reactive with other molecules in our cells. When these particles react with our cells, they can damage our DNA, cell membranes and other cell structures. This process is known as oxidative stress.

Oxidative stress is a natural process that happens when free radicals react with various molecules in our cells, including proteins, DNA, and cell membranes. Although some oxidative stress is necessary for our body’s normal functions, too much oxidative stress is linked to several diseases such as cancer, cardiovascular disease, Alzheimer’s disease, and other chronic conditions. Oxidative stress can also increase inflammation and accelerate the aging process.

Reducing oxidative stress from free radicals is possible through what we eat and do. Antioxidants are essential for our bodies to fight against free radicals and prevent oxidative stress. These antioxidants work by donating an electron, stabilizing and reducing the number of free radicals in our bodies. Drinking ample amounts of water and engaging in regular exercise can also help reduce oxidative stress.

Because they are so reactive, they have the ability to cause oxidative stress, which can damage DNA, protein, carbohydrates and lipids in the body and potentially cause disease. Free radicals develop in the body naturally as it converts food to energy, but other factors can increase exposure like cigarette smoke and air pollution. Research associates oxidative stress with an increased risk for conditions like:

What are the Benefits of Antioxidants?

Antioxidants can prevent oxidative stress, a process that occurs when there is an imbalance between free radicals and antioxidants in the body. This imbalance can cause damage to cells and lead to chronic inflammation, which can lead to various health problems, including heart disease, cancer, and autoimmune disorders. Antioxidants neutralize these harmful free radicals and reduce the risk of developing chronic diseases.

They are popular as dietary supplements, but there are also a ton of foods high in antioxidants like almonds, avocado, brown rice, berries, leafy greens, beef and poultry.
