Free Radicals and Antioxidants

Oxygen is not only necessary to breathe.

It also intervenes in cell regeneration and obtaining energy.

As these body processes are carried out, chemical substances considered as waste are produced.

These substances are called free radicals.

Dr. Lauri Wright, Assistant Professor of Nutrition at the University of South Florida says:

“Basically, I think of free radicals as waste products from various chemical reactions in the cell that when built up; harm the cells of the body.”

Our body naturally produces free radicals and our organism is prepared to fight the amount produced.

However, certain circumstances can accelerate their production beyond what our internal defense mechanisms allow.

Among them, we can mention:

  • Industrial pollution,
  • Tobacco,
  • Radiation,
  • Chemical additives in processed foods, and
  • Pesticides.

To make matters worse, as we get older, our body is progressively losing its ability to fight free radicals.

The result of this condition is more free radicals and more cellular deterioration, or oxidative stress.

Oxidative Stress

Oxidative stress

It is associated with almost all known chronic diseases.

Including atherosclerosis, inflammatory condition and certain types of cancers.

It’s also linked with aging…

The free radicals produced by the body to carry out certain functions are easily neutralized by our own system.

The problem occurs when the body has to withstand and fight an excess of free radicals for years.

Our body system is not biologically and anatomically prepared to handle the additional workload.

This excess of free radicals must be neutralized.

If it is not done, it will reside as waste with unpredictable consequences.

How does the body get rid of the excess of free radicals?

Through self-generated antioxidants.

Antioxidants may prevent or delay some types of damage to our body’s cells.

They provide protection against excess levels of free radicals.

They also ensure that free radical levels are kept in a finely tuned balance.

Antioxidants prevent free radical induced tissue damage by:

  • preventing the formation of radicals,
  • scavenging them,
  • or by promoting their decomposition.

They are intimately involved in the prevention of cellular damage.

This is the common pathway for cancer, aging, and a variety of diseases, as previously mentioned.

Antioxidants play a substantial function in our health, as they may help manage how quickly we age by fighting free radicals.

Our body produces some degree of antioxidants.

We can also get them in different meats, vegetables, fruits and berries.

Common antioxidants include

1.Vitamin E

This antioxidant is present in vegetable oils nuts, such as almonds, peanuts, and hazelnuts.

We can also found it in seeds (sunflower seeds) and green leafy vegetables (spinach and broccoli).


Turmeric is the spice that gives curry its yellow color.

Curcumin is the main active ingredient in turmeric.


Green tea is one of the substances with greater antioxidant properties.

It is characterized by containing 30% of polyphenols, among which phenolic acids and flavonoids stand out.

When not fermented, the vitamin, antioxidant and medicinal components in the leaves remain intact.

In addition to being found in green tea, polyphenols are also found in abundance in foods such as dried spices, fruits, vegetables, red wine and cocoa.

Red grapes, GRAPE seeds and red wine are the main sources of resveratrol.

But it is also present in blackberries, bitter chocolate and peanuts.

5.Vitamin C

Strawberries, citrus fruits (orange, grapefruit, and lemon), papaya, kiwi, guava, paprika.

Dark green leaves (Swiss chard and spinach) and broccoli are sources of this vitamin too.


The following foods are rich in this mineral:

  • Fish
  • Meat
  • Poultry
  • Liver
  • Cereals
  • Sesame
  • Milk
  • Vegetables
  • Nuts
  • Garlic


These are some of the foods richest in lutein:

  • Carrots
  • Spinach.
  • Coles.
  • Turnips.
  • Corn.
  • Broccoli.
  • Eggs.
  • Green peas


The human body can assimilate zinc directly from the meat.

That is why the intake of pork and lamb and veal liver is recommended.

This mineral is also found in pumpkin seeds, cheese, peanuts, nuts, chocolate and wheat germ.


Lycopene is a vegetable pigment belonging to the family of carotenoids.

It is responsible for giving vegetables and fruits the color red or orange.

We can found it in fruits and vegetables with those colors:

  • Watermelons,
  • papayas,
  • pink grapefruit,
  • guava,
  • strawberries,
  • currants,
  • cranberries,
  • cherries,
  • red pepper,
  • apricot,
  • carrot,
  • red cabbage and tomatoes, among others.

The vitamins and minerals that have antioxidant properties are essential nutrients.

This means that we need them for other aspects of our health.

10.Rosemary Extract

The extract of this aromatic shrub owes powerful antioxidant and antimicrobial properties.

Those properties are due to the content of total phenols, such as rosmanol acid and carnosic.

Those substances are naturally in the leaves and flowers of the plant.

11.Olive Leaves Extract

The benefits of this extract are due in large part to its high oleuropein content.

This substance helps reduce the risk of cardiovascular diseases.

That is because it inhibits the oxidation of lipids in the blood.

The antioxidant activity of olive leaf extract is even greater than that of green tea.

Do I need to eat all this?

Yes, we all should eat them regularly.

But it is important to consult with your doctor before starting to consume them.

Antioxidants are present in a variety of foods.

However, many people have an inadequate diet, triggering them to miss essential nutrients, including antioxidants.

In these circumstances, the intake of food supplements that compensate for this deficiency of antioxidants is recommended.

Stress is a common cause of free radicals production in the body that can hasten the aging process.

The antioxidant supplements fight free radicals.

So they can also help fight the negative effects that stress has on your body.
