The key to staying healthy is reducing your exposure to free radicals.

Not sure how to avoid them?

In this article, we’ll cover what causes free radicals and the sources of free radicals so you can avoid them and fight them off when need be.

What are Free Radicals?

To put it simply, free radicals are unstable molecules that wreak havoc on the cells in your body. They come together when the atoms or molecules in your body gain or lose electrons. They can also be the result of your standard metabolic processes.

Why are Free Radicals Bad?

In small doses, not much free radical damage occurs. But if you surround yourself with many sources of free radicals your body will begin to function poorly. Too much free radical exposure can lead to wrinkled skin, artery damage, and plaque buildup which can cause blood clots.

These issues can ultimately contribute to the development of the diseases and illnesses mentioned above.

4 Common Sources of Free Radicals

Did you know free radicals can be found in many of the foods we eat and things we interact with on a daily basis? Here are 4 common sources of free radicals:


Did you know that one of the many components of tobacco smoke are oxidants? These oxidants lead to an increase in free radicals, which will ultimately cause even more oxidative damage in your body. The main way to avoid this type of free radical is to quit smoking altogether.

Not sure you want to quit smoking? Just know that cigarette smoke negatively impacts nearly all of your organs, and can lead to a variety of diseases like lung cancer.

Fried & Greasy Foods

Are you a big fan of things like deli meats, bacon, and fatty fried foods? Well, unfortunately, all of these things are common sources of free radicals. Many of the preservatives involved in deli meat lead to an increase in free radicals and heating fats and oils at high temperatures can do that as well.

The key to eliminating these sources of free radicals? Try to avoid saturated fats and avoid processed meats. Instead, try to buy fresh meats and grill your meats instead of frying them, and eat healthy and organic whenever possible.


Alcohol is another common source of free radicals. The way it creates free radicals in your body can even put you at higher risk of cancer. So, if you’re a casual drinker, try to limit your alcohol intake to around 1 or 2 drinks a day to avoid free radicals.


Did you know that exposure to chemicals like pesticides and air pollutions can actually accelerate the development of free radicals? Many of the common beauty care and cleaning products we use can cause them, so read your labels to see what’s in the products you’re using.

And when possible, always go with non-toxic alternatives for personal care products.
