  • Antioxidants are substances found in many foods that help fight harmful free radicals in the body.
  • Free radicals arise as byproducts of metabolism and can lead to cell damage, which is linked to various diseases.
  • Antioxidants neutralize free radicals, helping to prevent cell damage and promote health.
  • A balanced diet with a wide range of fresh fruits, vegetables, whole grains and superfoods such as Guayusa provides a variety of antioxidants.
  • Guayusa is an exceptional source of antioxidants with a high ORAC value, which highlights its antioxidant properties.

1. What exactly are antioxidants?

Antioxidants are molecules that are able to inhibit or prevent the oxidation of other molecules. Oxidation is a chemical reaction that can produce free radicals. Free radicals can start chain reactions that eventually lead to Damage or death of cells being able to lead.

Oxidative stress occurs when there is an imbalance between the production of free radicals and the body's ability to neutralize or repair their harmful effects. This imbalance can lead to various things health problems including inflammation, aging and diseases such as cancer, heart disease and neurodegenerative disorders such as Alzheimer's.

Antioxidants, either produced by the body or obtained through diet, play a crucial role in defending against these harmful processes. They do this by "intercepting" and neutralizing the free radicals before they can cause damage.

There are a variety of different antioxidants, each with their own specific functions and mechanisms. These include vitamins (such as vitamins C and E), minerals (such as selenium), enzymes (such as superoxide dismutase, catalase, glutathione peroxidase) and botanicals (such as flavonoids, phenols and polyphenols).

It is important to note that not all antioxidants are created equal. Each antioxidant has its own specific function and can work in specific types of cells or tissues. Therefore, a diverse diet that provides a wide range of foods is essential for optimal health.


How exactly do antioxidants work?

They work by neutralizing free radicals. Free radicals are highly reactive molecules with unpaired electrons that can have harmful effects on our cells and tissues. They can be caused by various processes and reactions in the body as well as by environmental factors such as UV light, pollution and cigarette smoke arise.

Free radicals can cause cell damage by attacking cell membranes, oxidizing proteins and lipids, and even causing DNA changes. Over time, such damage can lead to chronic inflammation and various diseases including Heart disease, diabetes, cancer and neurodegenerative diseases, lead.

Antioxidants neutralize free radicals by “donating” one or more of their electrons. This neutralizes the free radical and prevents it from causing further damage. Some antioxidants can even help repair damage that has already occurred.

Our body needs both endogenous (produced in the body) and exogenous (supplied through diet) antioxidants. While our body can produce its own antioxidants, it also relies on dietary intake of antioxidants, especially those that it cannot produce on its own, such as Vitamin C and E.

For this reason, a balanced, nutrient-dense diet that includes a variety of antioxidant foods is critical to maintaining health and preventing disease.


The role of antioxidants in our body

Antioxidants play a crucial role in our body by protecting us from the damaging effects of oxidative stress and free radicals. They will therefore also be in Supplements and Nootropics like from the company NutriBrain used.

One could compare their role in our body to that of a guardian. The free radicals could be viewed as invaders trying to cause damage. The Guardians are constantly on guard, ready to ward off these intruders and prevent any damage.

They intercept free radicals and neutralize them before they can damage cells and tissue. In doing so, they protect us from oxidative stress and support our general health and well-being.

The sources of antioxidants

Antioxidants are found in a variety of sources, especially our food. They are found in many fruits and vegetables, nuts, seeds and spices. Antioxidants are also present in some drinks, such as tea and coffee.

Foods with a particularly high content include:

  1. dark berries such as blueberries, raspberries and strawberries,
  2. green leafy vegetables like spinach and kale, and
  3. Spices like turmeric and ginger as well
  4. Nuts and seeds, such as walnuts and flaxseeds.

However, there isn't just one type of antioxidant. Different foods contain different species, each of which works in different ways. Vitamin C and E, beta-carotene and selenium are just a few of the many types found in our food.

This is what makes a varied and balanced diet so important. By consuming a wide range of nutrient-dense foods, we ensure that our body receives the different types of antioxidants it needs to function optimally.

The ORAC value

When we talk about antioxidants, one cannot help but mention the ORAC value. ORAC stands for “Oxygen Radical Absorbance Capacity”. It is a method developed to measure the antioxidant capacity of different foods.

The ORAC value indicates how well a food or substance can neutralize free radicals. The higher the ORAC value, the greater the antioxidant capacity. A high ORAC value in a food or drink means that it has a strong ability to neutralize the harmful free radicals that can damage our bodies.

Understanding the ORAC value can help us make more informed decisions about our diet. When it comes to protecting our body from the harmful effects of free radicals, the ORAC value is an important factor to take into account.
