Types of Antioxidants

Antioxidants are of various types, each with distinct characteristics and roles in our body.

Enzymatic Antioxidants

These are proteins with the innate ability to neutralize free radicals for example catalase and glutathione peroxidase.

Enzymatic antioxidants act as biological defenders, scavenging harmful molecules and maintaining cellular balance.

Non-Enzymatic Antioxidants

They are not proteins but rather encompass a broad range of compounds, including vitamins, minerals, and phytochemicals.

Non-enzymatic antioxidants work synergistically to combat oxidative stress and provide robust protection against free radicals.

Examples include melatonin and glutathione.

Vitamins

Vitamins A, C and E are antioxidant vitamins. They help protect cell membranes against oxidative stress, support eye health, and boost your immune system.

Vitamin C is considered one of the best antioxidants for skin. It is known to play a crucial role in supporting your immune system and promoting collagen production.

They can be found in foods like amla, guava, berries, cantaloupe, spinach, kale and many more.

Minerals

Selenium and zinc are the minerals that act as trace elements with mighty antioxidant impact. Selenium becomes a crucial component of antioxidant enzymes, and zinc contributes to the defence against oxidative stress, highlighting their indispensable roles in maintaining cellular resilience.

They can be found in Brazil nuts, almonds, sunflower seeds and pumpkin seeds.

Polyphenols

Polyphenols, abundant in various plant sources, exhibit distinct identities and antioxidant properties. From resveratrol in grapes, renowned for cardiovascular health, to quercetin in onions with anti-inflammatory benefits, and curcumin in turmeric offering diverse health support, polyphenols bring superb protective qualities to the table.

Flavonoids

Flavonoids are a diverse group of antioxidants found in plant-based foods such as berries, tea, cocoa, and red wine. These compounds have anti-inflammatory and antimicrobial properties, protect against heart disease, and may even help improve cognitive function.

Antioxidants Benefits

This section will tell you the reasons why your diet should be antioxidant-rich. Let’s talk about the impressive health benefits of antioxidants, backed by references to reputable studies.

1. Protect Against Oxidative Stress

The primary antioxidant function is to act as a safeguard against free radicals. Oxidative stress is a result of an imbalance between free radicals and antioxidants in our body. By neutralizing free radicals, antioxidants help restore this balance, reducing the risk of chronic diseases such as cancer, diabetes, and heart disease.¹

2. Delay Ageing and Promote Youthful Skin

Who doesn’t aspire to have radiant and beautiful skin?

In the pursuit of a glowing complexion, antioxidants play a pivotal role.

Free radicals can accelerate the ageing process, leading to wrinkles, fine lines, and sagging skin. Antioxidants, particularly vitamins C and E, combat this damage, helping to preserve a youthful appearance and promoting collagen synthesis for healthy skin.

Antioxidants are being extensively used in dermatology.

A study found that lutein carotenoid – a potent antioxidant is associated with reducing oxidative damage from sunlight blue light². This makes it beneficial in the treatment of macular degeneration.

Antioxidants like vitamin C have also been shown effective in treating melasma. It reduces dopaquinone (DOPA), preventing the formation of free radicals.³

For those seeking a vibrant and youthful appearance, make antioxidants as an essential element in your skincare regimen.

3. Boost Immune Function

Regular consumption of antioxidants strengthens the immune system, aiding in the body’s defence against infections.

A robust immune system is essential to defend against infections and diseases.

Antioxidants, namely vitamin C, zinc, selenium, copper and beta-carotene, support the immune system by strengthening the function of white blood cells and promoting the production of antibodies, keeping you healthy and resilient.

Dietary antioxidants exert a protective effect on our body against bacteria and viruses. They strengthen the functioning and regulate the actions of immune cells.⁴

4. Enhance Heart Health

Antioxidants, specifically flavonoids, have been extensively studied for their potential to protect against heart disease. They help reduce inflammation, lower blood pressure, improve circulation, and prevent the oxidation of cholesterol, thus reducing the risk of cardiovascular problems.

Multiple studies have found a significant correlation between increased antioxidant intake and a reduced risk of cardiovascular diseases.

Oxidative stress promotes atherosclerosis and increases the risk of coronary artery disease. Natural antioxidants like vitamins A, C and E and glutathione reduce plaque formation in the arteries and mitigate inflammation.⁵

Chronic inflammation is one of the causative factors of heart disease. Patients suffering from inflammatory diseases often show diminished levels of antioxidants due to insufficient dietary intake.

Researchers suggest an intake of natural antioxidants as an effective strategy in fighting inflammation and endothelial disruption.

Another study conducted on 2252 men and 2849 women observed that people who consumed a diet rich in fruits and vegetables were less prone to cardiovascular disorders.⁶

5. Support Brain Health

Your brain is susceptible to oxidative damage due to its high metabolic activity.

Antioxidants, such as flavonoids, have demonstrated neuroprotective effects, improving cognitive function and reducing the risk of neurodegenerative diseases like Alzheimer’s and Parkinson’s.

Our brain cells have a high rate of oxidative metabolic activity. Antioxidants like superoxide dismutase and glutathione peroxidase not only protect the brain tissue from oxidative damage but also repair the damaged cells.

They ensure the smooth functioning of signalling pathways and minimize the effect of substances that stimulate oxidative radicals and the risk of neurodegenerative diseases.⁷

Conzyme Q10, zinc, selenium, vitamins E and A are critical antioxidants for our brain.

6. Mitigate Diabetes Risk

With diabetes on the rise globally, affecting millions, maintaining a healthy diet is pivotal in managing and preventing this widespread condition. Unhealthy dietary habits, often linked to processed foods and excessive sugar intake, contribute significantly to the increasing prevalence of diabetes.

Certain antioxidants, like those found in cinnamon and green tea, may help mitigate the risk of diabetes.

Obesity, sedentary lifestyle and lack of physical activity are the common causes of diabetes. However, excess free-floating radicals and oxidative stress in the body can also increase the incidence of diabetes.

Antioxidants such as N-acetylcysteine, vitamin C and alpha-lipoic acid are considered effective in reducing diabetic complications.

A study found that the oral administration of lipoic acid significantly improved insulin sensitivity among people with type 2 diabetes.⁸

Hence, it won’t be wrong to say that a diet packed with seasonal fruits and vegetables might therefore help treat diabetes and its complications.

7. Suppress Inflammation

Chronic inflammation is one of the causative factors of an array of illnesses like diabetes, gout, cancer, hypertension, arthritis, heart disease, and brain and endocrine disorders.

Anti-inflammatory compounds like flavonoids and polyphenols alleviate inflammation by blocking two major signalling pathways which have the main role in the production of various pro-inflammatory markers.⁹

Therefore, focusing on dietary antioxidants like tocopherols, carotenoids, and ascorbic acid is vital to safeguard your body against these inflammatory mediators.

8. Improve Vision Health

In this digital era of laptops and mobiles, prioritizing eye health is paramount. Prolonged screen time can contribute to digital eye strain, causing symptoms like dryness and blurred vision.

Antioxidants like lutein and zeaxanthin are essential for healthy vision health.

They have been shown fruitful in the treatment and prevention of various eye conditions like cataracts, glaucoma, age-related macular degeneration (AMD), diabetic retinopathy, and infections. 

An antioxidant-rich diet such as carotenoids, anthocyanins, and vitamins may help retain better vision, prevent the increase in oxidation-induced cytokines and keep the retina healthy.

A regular intake of oral lutein found a notable increase in optical density and visual acuity during clinical trials.¹⁰

9. Arthritis Prevention and Management

Arthritis is an inflammatory condition which causes pain, loss of function, and disability. Antioxidants have been discussed as an alternative treatment during such conditions to prevent or reduce the damage caused to the cartilage.

As already discussed antioxidants are super effective in relieving pain and inflammation via their anti-inflammatory effect.

To understand this effect, several studies have also been conducted. Researchers observed an improvement and increase in muscle strength, better physical functions, and a decreased risk of disease progression.

In addition to dietary sources, antioxidant supplements containing foods or extracts like curcumin, vitamin C, flavonoids, green tea, ginger, and fish oil can also be considered.

10. May Support Cancer Prevention

Cancer stands as a major global cause of death, claiming around 10 million lives worldwide. Statistics indicate an estimated 28.4 million cases expected by 2040, marking a 47% surge from 2020.

While age, genetic mutations, environmental influences, and lifestyle choices are a few factors influencing carcinogenesis, oxidative stress emerges as a significant contributor.

Oxidative stress and free radicals have the potential to cause damage to DNA, proteins, and lipids, thereby facilitating mutations and cellular changes that stimulate cancer progression.

Numerous clinical trials have explored the role of antioxidant supplements in cancer prevention. Some studies suggest that antioxidants like vitamin A, vitamin C, and vitamin E may lower the risk of specific cancers.¹¹

Antioxidants may help prevent or reduce cancer progression by preventing tumour cells from multiplying. inhibiting their multiplication, and killing the cancer cells.

People suffering from cancer can consider including antioxidant tablets or foods in their diet but only under medical supervision.
