Can Oxidative Stress Cause Health Issues

What is Oxidative Stress?

Oxidative stress is basically a lack of balance between the ability of the body to counteract the negative effects of oxygen free radicals and the production of oxygen free radicals. Oxidative stress can cause changes to the DNA of cells that can ultimately lead to disease—even cancer is believed to be related to oxidative stress. So can Oxidative stress make you sick? Worse, it could kill you.

Free radicals, Antioxidants in Disease and Health

An oxygen free radical is a molecule containing oxygen that has at least one unpaired electron. As a result, this makes the molecule extremely reactive with other molecules inside the body. They scavenge for molecules to share their unpaired electron with. Also, creating molecular fusions that alter the structure and function of the cells.

The byproducts of this molecular fusion are normally non-reactive. However, some of these molecules can experience metabolic changes within the body that give rise to highly reactive oxidant molecules. Not all oxygen free radicals are damaging to the body. In fact, some of these molecules are helpful in killing off microbes and other invading pathogens.

Oxygen free radicals have the capability to interact chemically with various components in the cell, such as lipids (that make up the membranes of the cells), protein (that can be structural or enzymatic in nature), and even DNA (our genetic makeup).

What Are Antioxidants?

Antioxidants involve molecules that scavenge for oxygen free radicals, binding to them in a much safer way than binding with cellular components. In the absence of antioxidants, the cell is exposed to serious damage, including becoming cancerous.

Antioxidants prevent damage to the cells by binding to oxygen free radicals so that they don’t bind to crucial cellular molecules.

Oxidative stress happens whenever there is an imbalance between antioxidants and oxidants (oxygen free radicals).

What Is Damaged By Oxidative Stress?

Oxidative stress can account for many pathological conditions within the body.

Some of these include inflammatory diseases, heart attacks, heart failure, atherosclerosis, blood vessel disorders, fragile X syndrome, chronic fatigue syndrome, cancers, genetic mutations, and neurodegenerative diseases, like Alzheimer’s dementia and Parkinson’s disease.

What Are Some Oxidants?

There are several types of oxidants, including the following:

O2- (superoxide anion) 

This is an oxygen molecule that has one extra electron. It is a part of the electron transport chain. While it isn’t very reactive, it can release the iron from ferritin and from iron-sulfur proteins.

H2O2 or hydrogen peroxide

This is formed by the dismutation of O2- or by the direct reduction of the oxygen molecule. Furthermore, it can diffuse across cell membranes, as it is lipid soluble

OH- or Hydroxyl radical

This is formed by decomposition of peroxynitrite and the Fenton reaction. It is extremely reactive, being able to attack most cellular components

ROOH or organic hydroperoxide

This is formed by reactions with cellular structures, such as DNA and lipids inside the cells.


These are organic radicals that have oxygen-centered in them. Lipids participate in lipid peroxidation reactions. It is produced along with O2 by the radical addition to hydrogen abstraction or by radical addition to double bonds.

HOCl or hypochlorous acid

This is formed by a reaction between myeloperoxidase and hydrogen peroxide. It also is highly reactive and lipid soluble, meaning that it can cross cell membranes.

ONOO- or peroxynitrite 

This is formed in a reaction between oxygen and nitrous oxide. Also, it is soluble in lipids and is as reactive as hypochlorous acid.

What is Reduction?

Reduction or “redox potential” is the ability of a substance to lose or gain an electron. For example, a strong reducing agent will have a greater potential to transfer electrons.

When in the presence of oxygen free radicals, it will cause small changes in the redox potential of a cell, stimulating the cell’s antioxidant system in order to protect the body from the injuries caused by oxygen free radicals. If the reaction is severe enough, the cell can undergo programmed cell death, also known as apoptosis.

What are Food Sources Of Antioxidants

  • Purple, Red, and Blue Grapes
  • Red Berries
  • Nuts
  • Dark Green Veggies
  • Sweet Potatoes and Orange Vegetables
  • Tea
  • Whole Grains
  • Beans
  • Fish

Where else can I get Antioxidants?

Sometimes it is hard to eat our way there. Supplements are a great way to help “supplement”! But having the right ones are key. We recommend Rain Soul® as it has the antioxidants of 18-20 servings of fruits and vegetables. All while being a whole food seed based supplement. Click here for more info.
