Antioxidants: What Are They?

Antioxidants are compounds that shield your body from the damaging effects of free radicals, which are unstable molecules. The human organism produces free radicals when atoms gain or lose electrons, which are charged particles.

Not all free radicals are harmful. Cell division is one of the numerous biological processes in which they are crucial. Additionally, they facilitate communication between cells and aid in your body’s defense against illness.

However, an excessive accumulation of free radicals in the body can cause major harm to cells. Diabetes, high blood pressure, heart disease, and cancer may all be exacerbated by this.

Numerous fruits, vegetables, and other foods naturally contain antioxidants, which can also be obtained as supplements. They can also be found in various skin care products.

The Various Types: What Are They?

There are two main categories.

Endogenous Antioxidants
Antioxidant substances known as “endogenous antioxidants” are created naturally by the body. They can be found in non-enzyme molecules like bilirubin or uric acid, or as enzymes like catalase (CAT).

Exogenous Antioxidants
Exogenous antioxidants are those that the body cannot manufacture on its own. Because they must be received through food, most individuals are familiar with these antioxidants. Exogenous antioxidants include, for example:

  • Flavonoids and polyphenols are examples of phytochemicals.
  • Trace elements include the metal manganese the metal copper, selenium as well zinc.
  • Both C and E vitamins

Why do antioxidants matter?

Your body’s cells are the site of numerous chemical processes. These can occasionally produce byproducts called free radicals. Your body uses free radicals for vital purposes. The immune system of your body employs some to combat germs or viruses.

Free radicals can, however, result in “oxidative stress” if they accumulate in your body. Your health may suffer as a result of this cell damage.

Stress from oxidation can harm you:

  • eyes, which can result in cataracts and macular degeneration
  • heart, which leads to failure of the heart and high blood pressure, also known as hypertension.
  • brain, which causes Parkinson’s and Alzheimer’s disease;
  • joints, which causes arthritis;
  • lungs, which causes asthma and chronic bronchitis;
  • kidneys, which causes kidney failure

By neutralizing these free radicals, antioxidants can stop their harmful effects.

Benefits of Antioxidants:

Antioxidants may be able to reduce your risk of developing some diseases because of their ability to shield you from free radicals. However, the relationship isn’t always evident, particularly in the case of supplements.

However, there are numerous other health benefits to eating a lot of fruits and vegetables. Antioxidant-containing foods usually include:

  • High in fiber
  • minimal levels of cholesterol and saturated fat
  • Packed with nutrients and vitamins

Antioxidants to prevent cancer:

According to several studies, antioxidants may be able to stop some of the harm that free radicals may do, which can result in cancer. However, there is no scientific proof that taking antioxidant supplements may stop cancer. To find out if dietary antioxidants can lower your chance of developing cancer, additional study is required.

Eye antioxidants

The most common cause of permanent sight loss in those over 50 is age-associated macular degeneration or AMD. It occurs when degeneration of the macula, located far back in the eye, starts. It may eventually cause you to lose your field of vision.

Antioxidants can reduce the risk of AMD by as much as 25%. They can help you preserve more of your eyesight if you already have AMD.

Vitamin C and E can help minimize the risk of cataracts. These protein accumulations obstruct the frontal lens of the eye, leading to blurred vision. Additionally, antioxidants may decrease the development of cataracts, extending the time that patients can see clearly.

Heart-healthy antioxidants

The question of whether antioxidants reduce the risk of heart disease is hotly debated. On the one hand, studies have indicated that those who consume more fruits and vegetables are less likely to suffer from heart disease and stroke. Antioxidants may be the cause of this advantage, according to a preliminary study.

However, further research on antioxidant supplementation has not demonstrated the same advantages. According to some experts, this is because supplements include larger amounts of antioxidants.

Consuming foods high in antioxidants could be the key, but further study is required to see whether a true correlation exists.

Skin antioxidants

There is some evidence that the antioxidant vitamins C and E provide advantages for the skin, but additional study is needed. According to studies, using a vitamin C compound topically may be beneficial:

  • Reduce the visibility of wrinkles
  • When used in conjunction with broad-spectrum sunscreen, protects the skin from UV stress.
  • Reduce the visibility of black patches on the skin

Vitamin E as a moisturizer component seems to be beneficial:

  • Soften the skin
  • Cut down on moisture loss
  • Prevent solar damage to skin cells.

Healthy skin is also encouraged by a diet high in antioxidants, which includes whole grains, nuts, fruits, vegetables, and fatty fish.

Foods High in Antioxidants:

Antioxidant vitamins and minerals differ depending on the foods consumed.

Orange foods that contain the antioxidant beta-carotene include:

  • Carrots
  • Sweet potatoes
  • Squash
  • Pumpkin
  • Apricots

High amounts of beta-carotene are also found in certain green leafy foods, such as:

  • Kale
  • Spinach
  • Collard greens

The antioxidant lutein is also abundant in these plants.

An antioxidant called lycopene can be found in the flesh of pink, red, or orange fruits and vegetables. Examples include:

  • Watermelon
  • Papaya
  • Pink grapefruit
  • Tomatoes

Most Americans consume around 85% of their lycopene from tomatoes and tomato-derived foods.

Vitamin A, an antioxidant, occurs in three forms, the most well-known of which is retinol (vitamin A1). Foods rich in vitamin A include:

  • Carrots
  • Sweet potatoes
  • Egg yolks
  • Liver
  • Milk

Numerous fruits and vegetables contain significant levels of the antioxidant vitamin C, as well as

  • Poultry
  • Beef
  • Fish
  • Some cereals

Almonds are abundant in vitamin E, a powerful a powerful antioxidant. You can also find it in:

  • Broccoli
  • Mangoes
  • Various oils, such as maize, soybean, and safflower

Plant-based foods contain significantly more antioxidants than meat. Berries and berry products are near the top of the antioxidant scale.

  • Blackberries Wild strawberries
  • Cranberries

Numerous kinds of spices and herbs are also highly recommended.

In addition to fruits and vegetables, other meals contain antioxidants. They can be found in nuts, coffee, and even chocolates.

Antioxidants in coffee

Coffee beans include a range of antioxidants, ranging from:

Ingredients include cafestol, trigonelline, phenols, melanodins, and quinine.

Coffee is the item in the typical American diet that has the highest antioxidant content, according to the American Chemical Society. Coffee outperformed all other foods evaluated in terms of antioxidant content per serving size and frequency of intake.

Antioxidants in dark chocolate.

Dark chocolate is made from cacao pod seeds, which are then roasted to produce cocoa beans. Cocoa includes flavanols, which are antioxidants that may help protect the heart. Dark chocolate has greater quantities of antioxidants than milk or white chocolate because it includes more cocoa solids and less cocoa butter, milk, sugar, and oil.

Red wine contains antioxidants.

Red wine includes resveratrol, an antioxidant derived from red grape skin. It can also be found in peanuts and strawberries. Although the evidence is inconclusive, resveratrol appears to have the potential to kill cancer cells and improve cancer therapy efficacy.

Antioxidants in nuts

Nuts are an excellent source of antioxidants. it contains the highest antioxidant concentration of any tree nut. Peanuts, while being classified as legumes, contain a high concentration of antioxidants.

Antioxidant Supplements:

Supplements may appear to be a convenient method to obtain antioxidants. However, no supplement can replicate the health benefits of a diverse, balanced diet rich in colorful fruits and vegetables.

Also:

The FDA does not regulate dietary supplements. As a result, you can’t be certain that a supplement is helpful, safe, or contains what it promises.

Except for particular formulae designed for patients with macular degeneration, there has been little evidence that antioxidant supplements prevent or treat illness.

Medications may be unbalanced. For example, there are eight different types of vitamin E in meals. However, most supplements include only one type of vitamin.

Antioxidants in large concentrations may be dangerous.

While supplements can assist if you are weak in a certain nutrient, they cannot compensate for an imbalanced diet. Always with your doctor before taking one, especially if you are pregnant, breastfeeding, or on medication.
