Antioxidants are substances that prevent or delay cell damage. The body uses antioxidants to fight harmful effects of free radicals, which can lead to premature aging and disease. There are many fruits that contain antioxidants, including blueberries, cranberries, and strawberries. Fruits with antioxidant properties may help prevent cancer and heart disease. Some researchers believe that the consumption of certain fruits may reduce the risk of developing cancer.
Antioxidant vitamins
Vitamins C and E are the best-studied antioxidants in the body, and they have been shown to be very effective at neutralizing free radicals. Other vitamins with antioxidant activity include vitamin A, vitamin K, biotin and folic acid.
Antioxidant minerals such as selenium and zinc also have important roles in protecting your cells from damage by free radicals.
Lipoic acid is another antioxidant that has been found to be helpful for some people with diabetes; however, there is not enough evidence to recommend it for all people with diabetes.
Other nutrients that may help protect against oxidative stress include:
Omega-3 fatty acids from fish oil (EPA) or flaxseed oil (ALA)
Alpha-lipoic acid (ALA)
Coenzyme Q10 (CoQ10)
Antioxidants are natural or synthetic substances that can help prevent the oxidation of other, more reactive molecules. Oxidation is a chemical process in which the bonds that hold atoms together in a molecule, such as those in fats, proteins and DNA, are damaged. Oxidative damage is associated with many diseases and conditions, such as cancer and heart disease.
Antioxidants are found in a wide range of foods including fruits and vegetables, nuts, spices and some beverages like tea and wine. Some antioxidants are also available as dietary supplements.
Antioxidants are chemicals that can neutralize free radicals in your body. Free radicals are a byproduct of normal processes in your body, but they also come from environmental sources such as cigarette smoke, pollution and ultraviolet rays from the sun.
Free radicals can damage cells and tissues in your body and lead to aging, cancer and heart disease. Antioxidants help protect your cells from this damage.
The best way to get antioxidants is through your diet. You can get them from fruits and vegetables or take antioxidant supplements to boost your intake.
Here are some foods that are rich in antioxidants:
Berries: Blueberries, strawberries and raspberries contain anthocyanins, which help prevent oxidative stress in the brain and heart while reducing inflammation. These berries also have anti-inflammatory properties that help reduce symptoms of allergies and asthma.
Tea: Green tea contains catechins, which have been shown to protect against certain types of cancer such as breast cancer due to their anti-inflammatory properties. Black tea also has some antioxidant properties but not as many as green tea does because it has less catechins than its green counterpart does.
Spices: Cinnamon contains cinnamaldehyde, which is an antioxidant that may help lower blood sugar levels
Antioxidants are substances that may protect your cells from damage caused by free radicals. Free radicals are unstable molecules that can cause damage to cells and may contribute to certain diseases. Antioxidants work by reducing the number of free radicals in your body.
Free radicals are produced naturally as your cells burn energy, but they also come from outside sources, such as tobacco smoke, radiation and air pollution.
Antioxidant vitamins include vitamins A, C and E, as well as beta-carotene (a compound found in carrots). Many other foods contain antioxidants.
There is no scientific proof that taking antioxidant supplements will reduce your risk of chronic disease or slow aging. However, most experts agree that a diet rich in fruits and vegetables is beneficial for overall health and may help prevent some chronic diseases — including cancer — when eaten daily over time.
A diet rich in antioxidants can help boost your immune system and fight off disease. Antioxidants are substances that protect your body against damage caused by free radicals — molecules that can cause cell damage.
Antioxidants also help keep your body running smoothly, because they support the immune system, which fights off infections, and they support normal brain function.
Antioxidants are found in many fruits and vegetables, as well as some foods like nuts and seeds.
The following list shows the best sources of antioxidants:
Berries: Blueberries, cranberries and strawberries have the highest antioxidant levels of all fruits. They have a lot of vitamin C, which helps prevent cell damage caused by free radicals. Berries also contain anthocyanins, which are pigments that give fruits their color. Anthocyanins may help lower blood pressure and improve blood flow to the brain.[1][2]
Cherries: Cherries contain anthocyanins and vitamin C, both of which fight free radicals in the body.[3]
Antioxidants are substances that, when consumed in adequate quantities, can reduce the risk of certain diseases. Antioxidant vitamins include vitamins A, C and E. Other antioxidants are found in fruits and vegetables, such as beta-carotene and lycopene.
Antioxidants are substances that help protect your body from the damage caused by free radicals — unstable molecules produced during normal metabolic processes. Free radicals can cause damage to cells that can lead to disease and premature aging. Antioxidants neutralize free radicals before they can cause any harm.
Antioxidant vitamins
Vitamins A (retinol), C (ascorbic acid) and E (alpha-tocopherol) are antioxidants that are essential for good health. They help prevent cell damage caused by free radicals and may protect against chronic diseases such as cancer, cardiovascular disease and Alzheimer’s disease.
Other antioxidants
Polyphenols are a group of antioxidant compounds found in plants and some foods rich in polyphenols include tea leaves, cocoa beans, apples, red grapes and berries
Antioxidants are substances that neutralize the effects of free radicals. Free radicals are unstable atoms or molecules that can damage cells in your body. Antioxidants help protect your body from this damage.
The following list of antioxidant supplements is categorized by their main type of antioxidant compounds. This list includes both dietary supplements and food sources that contain antioxidants.
Vitamin C is one of the most well-known antioxidants, but it’s not the only one! Vitamin C helps prevent oxidative damage caused by free radicals, but it also has other functions in the body.
Beta carotene is a type of carotenoid (a group of naturally occurring pigments) that’s commonly found in orange fruits and vegetables like carrots and sweet potatoes. Beta carotene protects against cancer and heart disease, as well as eye diseases such as macular degeneration and cataracts. It also helps prevent sunburn when taken before exposure to ultraviolet light — but don’t rely on beta carotene alone! It’s better to use sunscreen with a sunscreen ingredient such as zinc oxide or titanium dioxide + vitamin E combination instead.
Lycopene is another type of carotenoid that gives tomatoes their bright red color. Studies show that lycopene
Antioxidants are a type of nutrient that may reduce the risk of certain diseases. Antioxidant vitamins include vitamins C, E, and A. There are also many other antioxidants found in food, including polyphenols, flavonoids, and carotenoids.
Antioxidants help protect the body from damage caused by free radicals. Free radicals are unstable oxygen molecules that can cause damage to DNA and cell membranes. They are produced as a natural byproduct of metabolism and exposure to stressors like pollution and cigarette smoke.
Some studies suggest that consuming large amounts of antioxidants may help prevent certain cancers and heart disease, but evidence is currently limited. Vitamin supplements may not be beneficial for everyone, so consult your doctor before taking any supplement or adding them to your diet.
Antioxidants are substances that can help protect cells from damage. They may help lower your risk of certain diseases, including heart disease and cancer.
There are several different types of antioxidants. The most popular are vitamins C and E (alpha-tocopherol) and beta-carotene, lycopene and lutein.
Antioxidants work by absorbing “free radicals” — molecules that harm cells. Some of these molecules come from the environment, such as pollution or cigarette smoke. Others are produced within the body when it uses oxygen to produce energy.
Antioxidants are substances that prevent or delay the oxidation of other molecules. Oxidation is a chemical reaction that transfers electrons or hydrogen from a substance to an oxidizing agent. Oxidation reactions can produce free radicals, which start chain reactions that damage cells. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions. They do this by being oxidized themselves, so antioxidants are often reducing agents such as thiols, ascorbic acid, or polyphenols. The antioxidant effect is a result of an increase in the concentration of thiol groups in the body, although there is also evidence for direct action as a result of radical scavenging activity by antioxidants.[1]
In many organisms and especially in humans, this process of oxidative stress has been implicated in aging and age-related degenerative diseases.[2] Therefore it is important to have systems in place that combat oxidative stress and promote antioxidant status.[3]
The term “antioxidant” was coined by Denham Harman in 1956[4] to describe the ability of certain enzymes to inhibit oxidation;[5] however, his use of the term was not related to today’s mainstream use
