Free Radicals – Those Are Bad, Right?

The term antioxidants is commonly thrown around now as health concerns and prevention of cancers and degeneration are widespread topics.

But what exactly does it mean?
Well, antioxidants are anti (against) oxidants.  They clean up oxidants.

But what are oxidants you ask?
Basically, during the metabolic process, that is when we break down foods for energy, there is a natural byproduct, or waste product.  These byproducts to the metabolic process are called oxidants, or reactive oxygen species, or free radicals.  Normally, with a balanced diet of whole unprocessed foods, these free radicals are easily cleaned up by the antioxidants in our food.  Problems arise when we have more free radicals than can be cleaned up naturally.  And high amounts of oxidation occur from diets that are high in sugar and omega-6 fats.

These two components put too much stress onto our metabolic process when consumed in high amounts, resulting in high amounts of free radicals.Too much free radicals leads to oxidative stress and oxidative damage. High oxidative stress, or chronic oxidative stress is a cause for chronic inflammation.  Think of it like there is a big mess from too much sugar and omega-6 fats and the immune system is having to work overtime to clean it up and as a result damage is happening to normal organ tissue in the body.

Just about all chronic illnesses, including autoimmune conditions, diabetes, cancers and neurodegenerative disorders are linked to chronic inflammation.

An excess of omega-6 fats from cereals, processed foods, and especially vegetable oils and spreads increases the risk of inflammatory, neurological, and degenerative diseases. These studies indicate strongly that limiting our intake of omega-6 is essential to the health of our brains.  For example, researchers have found a link between Alzheimer’s Disease and increased levels of an omega-6 fat called arachidonic acid, which they believe interferes with the brain’s nerve cells, causing overstimulation; lowering these levels lets the cells function normally again.

Changing our diets to reduce our intake of refined sugars, omega-6 fats, and highly processed and chemicalized foods will reduce oxidative stress and reduce overall inflammation, thereby reducing our risk for chronic illness and debilitating disease.

So, sugar is something worth reducing our intake of, not only because of the above reasons, but also because it can have such a drastic effect on our energy levels and mood.  Check out this article on ways to reduce sugar cravings.  And become a label reader.  Sugar has many forms and it’s best to be aware of hidden names and sources so you can be an informed consumer.
