In the ever-changing industry of health and wellness, “antioxidants” is a term that always comes up. But, what are antioxidants and why are they important? Whenever someone mentions superfoods or skin care, antioxidant is a label that tends to pop up alongside it.
However, little is known of their function, their benefits, and how do they impact the human body. Hence, this guide aims to cover the basics of everything one needs to know regarding antioxidants, the way they function, where to get them, and the reasons that make them critical for one’s well-being and longevity.
What Are Antioxidants?
Free radicals are neutralized by antioxidants, the powerful molecules. Each unstable atom is capable of damaging cells, leading aging and diseases like cancer, heart disease and other forms of diabetes. The accumulation of free radicals causes oxidative stress which eventually leads to DNA damage alongside essential proteins and other crucial molecules.
Curing free radicals is the main responsibility of antioxidants. Cell damages caused by reaction chains are stopped when electrons are donated by free radicals. Being so simple yet capable is the true essence of why everyone needs antioxidants.
What Are The Uses Of Antioxidants In The Body At The Cellular Level?
Antioxidants offer incredible protection to the body because they counter oxidative stress. Here is a summary of their function:
- Preemptively Avoid Cell Damage: Antioxidants arrest and obliterate free radicals which aid in cell damage.
- Curb Body Methuselah: They mitigate oxidative harm responsible for early aging as well as aging-related ailments.
- Strengthen Defense: Consumed in appropriate amounts, antioxidants bolster the immune system and lessen the inflammation.
- Fundamental Role in Enhanced DNA Accuracy: Antioxidants uphold the cellular repair systems and defend the organization of the genetic material.
- Banish ‘Toxins’: They give aid to the liver and kidneys in purging harmful toxins from the human body.
Forms and Specific Advantages of Antioxidants
Both man-made and natural sources of antioxidants abound. The following are the most common types:
1. Vitamin C (Ascorbic Acid)
- What it does: An antioxidant vitamin found in fruits such as oranges, strawberries, and kiwi, and has water soluble properties.
- Benefit: Bolsters immune system, enhances skin condition, and expedites wound recovery.
2. Vitamin E (Tocopherol)
- What it does: An antioxidant vitamin in oil found in nuts, seeds and leafy greens.
- Benefit: Guards the integrity of cell membranes, increases skin elasticity, and aids in eyesight.
3. Beta-Carotene (Precursor to Vitamin A)
- What it does: Derived from carrots, sweet potatoes, and spinach.
- Benefit: Aids vision, strengthens immunity, and promotes skin health.
4. Selenium
- What it does: A trace element available in Brazil nuts, eggs, and fish.
- Benefit: Improves the action of enzymes, reduces cancer risk, and shields the thyroid.
5. Polyphenols
- What it does: Extracted from tea, coffee, berries, dark chocolate, and red wine.
- Benefit: Supports cardio health, reduces inflammation, and enhances mental activity.
6. Flavonoids
- What it does: Extracted from fruits, vegetables, and herbs.
- Benefit: Improves blood flow, fortifies capillaries, and defends the nervous system.
Which Foods Contain Antioxidants?
Antioxidants can be easily be found in natural products like fruits and vegetables. Here are the foods that are abundant in antioxidants and should be consumed on a daily basis:
- Berries- which include blueberries, strawberries and raspberries.
- Spinach, Kale and Arugula are examples of leafy greens.
- Almonds, walnuts and flaxseed are types of nuts and seeds.
- Quinoa, oats and brown rice are examples of whole grains.
- Dark chocolate is also a source of antioxidants. The higher the content of cocoa, the better. 70% or higher is best.
- Legumes like black beans, lentils and chickpeas.
- Herbal a and spices such as tumeric, cinnamon and oregano.
- Green and black tea.
- Furthermore to that, red wine in moderation is also good for you.
Despite there being supplements on the market, it is far better to obtain your antioxidants from food as they have more vitamins, fiber, and other essential compounds.
What Do Antioxidants Do for Your Body?
Let’s examine the role of antioxidants in the body after learning their types and sources:
1. Reduces Inflammation
Chronic inflammation is one of the leading causes of many conditions such as arthritis, heart disease, and Alzheimer's. Antioxidants like curcumin (from turmeric) and resveratrol (from red wine) help manage the inflammation appropriately.
2. Boost Brain Health
Oxidative stress is dangerous and leads to the neurodegenerative disorders such as Parkinson's and Alzheimer's. Antioxidants guard neurons and enhance memory, attention, and higher cognitive processes.
3. Improve Heart Health
Flavonoids and polyphenol antioxidants enhance cholesterol levels, lower blood pressure, and prevent clot formation which decreases the chances of strokes and heart attacks.
4. Protect Skin from Aging
Free radicals from the sun and pollution lead to skin aging. Vitamin C and E stimulate collagen formation, reduces wrinkles, and improve skin radiance.
5. Supports Eye Health
The antioxidants lutein and zeaxanthin found in carrots and leafy greens defend the retina from blue light and lower the likelihood of macular degeneration.
6. Enhance Immunity
Cellular damage is fought off by antioxidants which help the white blood cells fight better making the person less susceptible to infections and illness.
The Science of Antioxidants
Numerous scientific studies have validated the positive effects of antioxidants on human health. Following are some of them:
- In one study, editors of the Journal of Nutritional Biochemistry demonstrated that polyphenols greatly decrease oxidative stress and enhance insulin sensitivity in type two diabetic patients.
- As reported by the American Journal of Clinical Nutrition, increased quantity of vitamin E and beta carotene decreases heart disease by 25%.
- Studies from the National Institute on Aging’s Research Centers showed that diets rich in antioxidants delay the decline in cognitive abilities and memory recall in aging adults.
These studies confirm that unlike many other claims, antioxidants are indeed nutrients that have scientifically proven importance to human health.
The Role of Antioxidants in Disease Prevention
Having knowledge of the benefits of antioxidants goes hand in hand with knowing the way they prevent diseases:
- Cancer Prevention
By neutralizing free radicals, antioxidants hinder the oxidative processes that cultivate cancer. Selenium and vitamin C have garnered attention for their anti-cancer potential.
- Diabetes Management
Antioxidants improve glucose metabolism and reduce diabetes complications by lessening oxidative damage to blood vessels and nerves.
- Heart Disease
They reduce “bad” LDL cholesterol, increase arterial circulation, and prevent plaque deposits which promote better circulation—these factors are vital in avoiding strokes and heart attacks.
- Eye Disorders
Cataracts and age-related macular degeneration (AMD) are mitigated by lutein, zeaxanthin, and vitamin C.
Should You Take Antioxidant Supplements?
Although antioxidant supplements are easily accessible, professionals in the field of health and nutrition advise against them. The harmful effects of too much certain antioxidants, especially in supplement form, is too great. For example:
- The risk of hemorrhagic stroke is increased by high doses of vitamin E.
- Smokers who are excessive beta-carotene supplementers are at risk of developing lung cancer.
Best advice: Unless directed by your physician, avoid supplements and rely on whole foods instead.
How to Naturally Increase Antioxidants Intake
Here is a list of ideas to increase antioxidants effortlessly:
- ‘Eat the rainbow’ – strive to eat fruits and vegetables of every color every day.
- ‘Snack smart’ – opt for nuts, berries, or dark chocolate instead of chips.
- Used ‘spice it up’ – put turmeric and cinnamon on everything.
- Drink green tea – drinking a few cups a day goes a long way.
- Go organic – organic products are known to have higher antioxidant levels.
