Do Antioxidant-Rich Foods Have Benefits for Psoriasis?

According to MedicalNewsToday, some studies have found that people with psoriasis have shown that antioxidant intake protects the immune system and limits the inflammation of psoriasis.

Do Antioxidant-Rich Foods Have Benefits for Psoriasis?

Antioxidants’ Influence in the Body

Antioxidants are beneficial to our bodies because they neutralize free radicals.

As we age, the generation of free radicals increases, and their quantity becomes greater than the capacity of our body’s antioxidant defenses, resulting in oxidative damage, much like rust on metal.

This phenomenon is called oxidative stress or cellular aging.

Antioxidants are simply good molecules (little soldiers) that transform these free radicals into harmless products and thus reduce their harmful effects on our health.

Antioxidants are essential in our daily diet to reduce oxidative stress in our body.

They are real shields to protect our healthy cells and our health!

Over the past few decades, free radicals have emerged as a major focus of interest in most bio-medical disciplines.

Research on several diseases increasingly shows that oxidative stress is associated with several diseases such as:

  • diabetes,
  • obesity,
  • cancer,
  • cardiovascular disease,
  • inflammation,
  • neurodegeneration,
  • hypertension,
  • aging.

What Are Antioxidants Supposed to Do, Which Benefits?

There are several advantages of consuming a good amount of antioxidants through the diet.

Here are the main examples of the functions of antioxidants for health:

  • They help neutralize the action of free radicals and prevent oxidative stress;
  • They offer anti-inflammatory effects;
  • Contribute to maintaining skin health and cell rejuvenation;
  • Help to protect the skin against sun damage;
  • Contribute to the prevention of heart disease.

Psoriasis is linked to an increase in oxidative stress markers and a decline in antioxidants.

An inflammatory response is triggered by this mismatch, which activates the immune system.

One of the contributing factors that induce and exacerbate psoriasis is an overactive immune system.

In patients with active psoriasis, there are consistent systemic symptoms of oxidative stress: plasma levels of malonyl dialdehyde (MDA) are substantially elevated, implying a loss of normal enzymatic and non-enzymatic antioxidant systems and, as a result, a prevalence of peroxidation processes in cell membranes and plasma lipid processes in circulating cells.

Antioxidants can eventually restore the balance, resulting in an anti-inflammatory effect, likely by activating antiproliferative and proapoptotic pathways in both local and inflammatory cells.

Types of Antioxidants and How Do They Act on the Organism?

Vitamins, minerals, and bioactive compounds present in food can play an antioxidant role.

They are available for consumption in several forms. See below:


Do you already know what glutathione is and what it is used for? Glutathione is considered the most powerful antioxidant produced by the body!

What makes it so special is that it has the unique ability to boost the action of other antioxidants, such as:

  • vitamins C and E,
  • coenzyme Q10,
  • alpha-lipoic acid.

Broccoli, Brussels sprouts, cabbage, cauliflower, avocado, peaches, watermelon, and cinnamon are examples of glutathione precursors that is, that serve as raw material for its production.


Beta-carotene acts as an antioxidant, helping to protect cells against the action of free radicals and to maintain skin health.

In addition, it contributes to lowering the risk of coronary heart disease, stroke, and other age-related health problems.

It is present in foods such as carrots, mangoes, and spinach. It is necessary for the synthesis of vitamin A.


It has the ability to act as an antioxidant compound, thus reducing the ability to cause cell damage.

It also helps to prevent cardiovascular disease and to improve insulin sensitivity.

You can find lycopene mainly in tomatoes.

The best way to consume tomatoes to take advantage of the antioxidant, unlike other vegetables, is cooked.

Vitamin A

It is significant for the skin. Vitamin A consumption helps keep tissue firm and active cells functioning well because it acts in collagen formation and cell renewal.

It is available in foods such as liver, egg yolk, and fish oil.

However, it is also worth remembering those we have already suggested in the item beta-carotene – which is transformed into vitamin A in the body.

Vitamin C

This is a powerful antioxidant that combats the action of free radicals.

It helps the body’s cells to grow and stay healthy. Well known, vitamin C is part of the composition of citrus fruits, such as oranges and lemons.

It is also found in the microalgae Chlorella.

Vitamin E

It is known as a natural antioxidant capable of protecting cells from the damaging effects of free radicals.

It slows down premature aging and helps prevent atherosclerosis.

To get vitamin E, look for foods such as papaya and avocado, and oilseeds, including pistachios, Brazil nuts, walnuts, and almonds.

Food Supplementation: When to Supplement?

Antioxidants are available as food supplements. They are available in drugstores and para-pharmacies and allow to overcome a dietary deficiency.

But their effectiveness is not so clear. The bio-availability of antioxidants is higher when consumed naturally (present in food and not in pills).

Antioxidants taken orally or topically should not substitute a diet rich in fruits and vegetables.

The combination of active ingredients enhances the effects while posing no risk.

People should usually eat a healthy, varied diet; however, vitamin deficiencies may occur in people who have had bariatric surgery, the elderly, or others with dietary restrictions.

It would be necessary to replenish in physiological doses.

Consult your dermatologist before starting supplementation.

Excessive Antioxidants: The Potential Dangers?

Overdosing on antioxidants can be dangerous for the body.

While the body will eliminate the extra vitamin C via the urine, vitamins A and E have taken over the long term expose the body to an increased risk of cancer.

Before taking them, ask your physician or pharmacist for advice.


A diet rich in antioxidants brings numerous benefits for psoriasis and your skin in general.

Always choose to consume them in their natural form and not in supplements, as the benefits of antioxidants will be much greater.
