Introduction:

When exposed to environmental or other stresses, our bodies develop free radicals, unstable molecules that cause cell damage. Antioxidants are compounds that help prevent or reduce cell damage caused by free radicals.

They are referred to as “free-radical scavengers” in some circles. Antioxidants can be obtained from various sources, both natural and artificial. It is believed that certain plant-based foods are exceptionally high in antioxidants. Plant-based antioxidants are a type of phytonutrient, which is a nutrient derived from plants. Some antioxidants, known as endogenous antioxidants, are produced by the body and the environment. Exogenous antioxidants come from outside the body and help protect the body from disease.

Free radicals are waste products produced by cells due to the body’s digestion and response to the environment. It is possible to experience oxidative stress if the body’s ability to handle and eliminate free radicals is impaired. This has the potential to harm cells and body function. Reactive oxygen species (ROS) are another term for free radicals (ROS).

Free radicals are produced in the body by various factors, internal, such as inflammation, and external, such as pollution, ultraviolet radiation, and cigarette smoke. According to reliable sources, cardiovascular illness, cancer, arthritis, stroke, respiratory diseases, immunological insufficiency (including emphysema and Parkinson’s disease), and other inflammatory or ischemic problems have been related to oxidative stress. Antioxidants are considered to aid in neutralising free radicals in our systems, which are thought to improve our overall health and well-being.

Antioxidants

Antioxidants are substances that prevent the oxidation of other molecules from taking place in the body. As a result of oxidation, free radicals are created, and these free radicals set off a chain of chemical processes that cause cell damage. These chain reactions can be stopped by effectively utilising antioxidants such as ascorbic acid and thiols. Biological systems, such as plants and animals, maintain an intricate network of overlaying oxidants and antioxidants to maintain an optimal oxidation state.

Antioxidants: Uses

• Antioxidants are commonly found in dietary supplements, and they are incredibly beneficial in the prevention of a wide range of ailments, including cardiovascular disorders and cancer.

• Antioxidants are also used in various other applications, including chemical reaction control in industry, food preservatives, and cosmetics.

Antioxidants have a Positive Impact on your Health

Antioxidants are beneficial to our health to a certain extent. Due to the limited amount of information available on the effects of antioxidants on the human body, it is impossible to predict the precise advantages and the potential adverse effects of using antioxidants in food.

Antioxidants have been proven to have potential impacts on neurodegenerative disorders such as Alzheimer’s disease, according to research. Foods containing fructose, which is commonly utilised for flavour enhancement, can benefit from the antioxidant qualities of fructose.

Tirilazad mesylate is an antioxidant steroid that slows the increase of lipid peroxidation, which plays a critical role in the death of neurons in the brain after a stroke or traumatic brain injury. Another oxidant, NXY-059, showed modest effectiveness in animal studies but failed to improve the outcomes of stroke patients when tested in clinical trials.

Antioxidants: Advantages

The presence of these compounds in many fruits helps to keep other molecules in our bodies from oxidising. Antioxidants are highly beneficial to one’s overall health. When left unchecked, free radicals in our bodies can cause illness and various chronic diseases. Antioxidants work by interrupting the sequence of reactions generated by free radicals.

There are numerous advantages to different antioxidants for different regions of the body. To provide just a few examples, beta-carotene is highly advantageous to our vision, lycopene is hugely favourable to prostate health, and proanthocyanidins are healthy to the urinary tract.

In today’s polluted world, increasing our antioxidant intake should improve the overall health of our bodies because our bodies are unable to create the necessary amount of antioxidants. Minerals, vitamins, and enzymes should all be present in sufficient quantities in our regular diet.

Disadvantages of antioxidants

• Consuming too many antioxidants in the form of supplements could lead to an increased risk of death and disease instead of having positive effects.
• Natural antioxidants can add colour and aftertaste  to food but they are less effective at slowing slowing rate of rancidity
• Antioxidants at greater concentrations act as pro-oxidants i.e increase oxidation.
• At High concentration ,they protect both dangerous and healthy cells.
• Antioxidants taken at high concentration  cause unwanted side effects such as nausea , diarrand , and headaches.

Foods High in Antioxidants

Because the antioxidants found in fruits, vegetables, whole grains, lentils, and nuts are complex and diverse, eating a variety of these healthy foods can help to ensure that you are getting enough of these disease-fighting nutrients.

The following are some ideas for introducing antioxidant-rich foods into your diet:

• At least one fruit or vegetable should be included in every meal.

• Choose brightly coloured fruits and vegetables that are abundant in nutrients and antioxidants. Blue, purple, crimson, orange, yellow, and green are just a few examples of colourful fruits and vegetables.

• Including antioxidants in your smoothies is an excellent way to reap the benefits of these potent molecules. Incorporate dark-coloured blueberries or blackberries into a fruit smoothie with citrus fruits, pineapple, apples, or pears.
• Antioxidants are found in grass-based diets, as well as legumes. When it comes to incorporating antioxidants into your daily diet, oats are an excellent source. Oatmeal and oat bran are two healthy options.

• Consume as many beans and lentils as possible. Red beans, kidney beans, black beans, and pinto beans are just a few legumes high in antioxidants.

• Cooking using antioxidant-rich herbs and spices like dried oregano, turmeric, cinnamon, cloves, and ginger is a terrific way to obtain your daily dose of vitamins and nutrients.

Cooking affects antioxidants

• It is possible to raise or reduce the antioxidant content of specific foods by cooking them.

• Lycopene is an antioxidant that contributes to the deep red colour of tomato fruits and vegetables. Increasing the availability of lycopene by heating tomatoes is beneficial (easier for our bodies to process and use).

• However, studies have found that cauliflower, peas, and zucchini lose a significant amount of their antioxidant potential when cooked. Remember that consuming a range of antioxidant-rich foods, both cooked and raw, is the most important thing you can do for your health.
