Benefits Of Antioxidants To Our Health
Antioxidants are substances that can prevent or slow damage to cells caused by free radicals, unstable molecules that the body produces as a reaction to environmental and other pressures.
They are sometimes called "free-radical scavengers."
The sources of antioxidants can be natural or artificial. Certain plant-based foods are thought to be rich in antioxidants. Plant-based antioxidants are a kind of phytonutrient, or plant-based nutrient.
The body also produces some antioxidants, known as endogenous antioxidants. Antioxidants that come from outside the body are called exogenous.
Free radicals are waste substances produced by cells as the body processes food and reacts to the environment. If the body cannot process and remove free radicals efficiently, oxidative stress can result. This can harm cells and body function. Free radicals are also known as reactive oxygen species (ROS).
Factors that increase the production of free radicals in the body can be internal, such as
inflammation , or external, for example, pollution, UV exposure, and cigarette smoke.
Oxidative stress has been linked to heart disease , cancer , arthritis , stroke , respiratory diseases, immune deficiency, emphysema, Parkinson's disease , and other inflammatory or ischemic conditions.
Antioxidants are said to help neutralize free radicals in our bodies, and this is thought to boost overall health.
BENEFITS OF ANTIOXIDANTS
Colorful fruits and vegetables can offer a range of antioxidants. Antioxidants can protect against the cell damage that free radicals cause, known as oxidative stress.
Activities and processes that can lead to oxidative stress include :
- mitochondrial activity
- excessive exercise
- tissue trauma, due to inflammation and injury
- ischemia and reperfusion damage
- consumption of certain foods, especially refin and processed foods, trans fats, artificial sweeteners, and certain dyes and additives
- environmental pollution
- exposure to chemicals, such as pesticides an drugs, including chemotherapy
- industrial solvents
Such activities and exposures can result in cell damage. This, in turn, may lead to:
- an excessive release of free iron or copper io
- an activation of phagocytes, a type of white b cell with a role in fighting infection
- an increase in enzymes that generate free radicals
- a disruption of electron transport chains
All these can result in oxidative stress. The damage caused by antioxidants has been linked to cancer, atherosclerosis, and vision loss. It is thought that the free radicals cause changes in the cells that lead to these and possibly other conditions. An intake of antioxidants is believed to reduce these risks.
According to one study: "Antioxidants act as radical scavenger, hydrogen donor, electron donor, peroxide decomposer, singlet oxygen quencher, enzyme inhibitor, synergist, and metal-chelating agents."
Other research has indicated that antioxidant supplements may help reduce vision loss due to age-related macular degeneration in older people.
Overall, however, there is a lack of evidence that a higher intake of specific antioxidants can reduce the risk of disease. In most cases, results have tended to show no benefit, or a detrimental effect, or they have been conflicting.
SOURCES OF ANTIOXIDANTS
The best sources of antioxidants are plant-based foods, especially fruits and vegetables.
Foods that are particularly high in antioxidants are often referred to as a "superfood" or "functional food."
To obtain some specific antioxidants, try to
include the following in your diet:
Vitamin A: Dairy produce, eggs, and liver
Vitamin C: Most fruits and vegetables, especially berries, oranges, and bell peppers
Vitamin E : Nuts and seeds, sunflower and other vegetable oils, and green, leafy vegetables
Beta-carotene : Brightly colored fruits and vegetables, such as carrots, peas, spinach, and
Lycopene : Pink and red fruits and vegetables, including tomatoes and watermelon
Lutein : Green, leafy vegetables, corn, papaya , and oranges
Selenium: Rice, corn, wheat, and other whole grains, as well as nuts, eggs, cheese, and legumes
