Antioxidants can be found in many different foods and most scientists agree that as little as five help reduce the risk of cancer. According to recent studies: Tart cherries can reduce muscle pain and soreness caused by exercising. Strawberries are full of antioxidants and can help improve eyesight. Red cabbage is high in antioxidants and can lower the risk of breast cancer.Kale is known for its super antioxidant properties.
Vegetables high in antioxidants
Vegetables are good sources of antioxidants. Some vegetables have more antioxidants than others, however. Here are some examples:
Beets. Beets contain betalains, which are pigments that give beets their color. Betalains help protect the body against cancer and heart disease. Beets also contain fiber, folate and potassium. They’re an ideal choice for anyone looking to improve their diet or lower their risk of chronic disease.
Broccoli. Broccoli contains sulforaphane, which is thought to help prevent certain cancers and other diseases by boosting the immune system and protecting cells from damage caused by free radicals (a type of oxygen molecule that can cause damage in your body). Broccoli is also an excellent source of vitamin C and fiber, both of which provide antioxidant benefits to your health as well.
Brussels sprouts. Brussels sprouts contain glucosinolates, which help protect against inflammation-related illnesses such as heart disease, arthritis and asthma. They’re also rich in vitamin C and beta carotene as well as other nutrients that provide antioxidant benefits to your health such as folate, potassium and fiber (1).
Antioxidants are substances in food that may help protect your cells from damage.
These include vitamins C and E and beta-carotene.
The most powerful plant antioxidant is lycopene, which is found in tomatoes, watermelon, pink grapefruit and papaya. Other good sources of lycopene include guavas, pink guavas, apricots, pink grapefruit and red bell peppers.
Vitamin C is found in citrus fruits such as oranges and grapefruits; green vegetables such as spinach and broccoli; red bell peppers; strawberries; kiwis; cantaloupes; Brussels sprouts; cauliflower; potatoes and white button mushrooms.
Beta-carotene is found in carrots, sweet potatoes, winter squash (such as acorn), spinach, kale, collard greens and turnip greens. Other sources include sweet red peppers (sweet peppers) like jalapeno or cayenne peppers and tomatoes
Antioxidants are substances that can protect your body from damage caused by free radicals. Free radicals are unstable molecules that form as part of normal cell metabolism and also as a result of exposure to environmental factors such as cigarette smoke, air pollution and radiation.
The body has its own antioxidant systems to fight free radicals. These include enzymes such as superoxide dismutase (SOD), catalase and peroxidase, which prevent the formation of harmful reactive oxygen species (ROS).
Antioxidants can also be obtained from food sources. Antioxidants in food act like SOD, catalase and peroxidase in the body, by neutralising free radicals before they can cause damage to cells.
Antioxidants are substances that prevent or delay the oxidation of other substances. Oxidation is a type of chemical reaction that involves the removal of electrons, often producing free radicals.
Antioxidants counterbalance this process by removing free radicals or reducing their effects.
There are two types of antioxidants:
Natural antioxidants are found in nature and include vitamins C and E and beta-carotene.
Synthetic antioxidants are man-made compounds such as butylated hydroxyanisole (BHA) and butylated hydroxytoluene (BHT). They can be used in combination with natural antioxidants to extend their shelf life.
Antioxidants are compounds that prevent or delay oxidation, a process involved in the deterioration of food and products during storage or exposure to air. In general, oxidation is a chemical reaction that transfers electrons from a substance to an oxidizing agent. Oxidation reactions can produce free radicals, which start chain reactions involving other substances. Antioxidants terminate these chain reactions by removing free radical intermediates, and inhibit other oxidation reactions.
Antioxidant activity can be evaluated using in vitro assays like the oxygen radical absorbance capacity (ORAC) assay and the 2,2-diphenyl-1-picrylhydrazyl (DPPH) test (which evaluate the ability of antioxidants to donate electrons). In vivo, one of the best measures of antioxidant activity is the ferric reducing/antioxidant power (FRAP) assay; however it does not measure all antioxidants but only those that reduce Fe3+ to Fe2+, such as ascorbic acid, glutathione and uric acid.
Which vegetables contain antioxidants?
Vegetables are a rich source of antioxidants. Antioxidants are chemicals that fight cell damage and slow the aging process. They are naturally present in all foods, but some vegetables have more than others.
Foods rich in antioxidants include:
Apricots: A serving of apricots contains about 3 milligrams (mg) of vitamin C and 0.8 mg of alpha-tocopherol (vitamin E). This provides nearly 20 percent of the recommended daily intake of vitamin C and 7 percent of the recommended daily intake of vitamin E.
Avocados: Avocados contain more than five times as much beta-carotene as carrots and three times as much lutein as spinach. B vitamins, vitamin K, folic acid, potassium, magnesium, selenium and zinc are also found in avocados. They also contain oleic acid, which may help prevent heart disease by lowering blood cholesterol levels and preventing platelets from sticking together to form clots in your arteries (blood vessels).
Beets: Beets contain a variety of minerals including iron, calcium, magnesium and manganese as well as phytochemicals such as betal
Antioxidants are substances that may prevent or delay some types of cell damage. These include damage from free radicals and inflammation, which are believed to be involved in conditions like heart disease, cancer, and Alzheimer’s disease.
Plant foods contain a variety of phytochemicals that act as antioxidants. Some of the most common antioxidants are vitamin C, vitamin E and carotenoids (such as beta-carotene).
Antioxidants are found in all fruits and vegetables, but some have more than others. For example:
Dark green leafy vegetables such as spinach and kale contain lots of carotenoids. Other dark green vegetables such as broccoli and Brussels sprouts also contain carotenoids but not as many as dark greens.
Tomatoes are rich sources of lycopene, an antioxidant that may help protect against prostate cancer in men who eat tomatoes regularly.
Red peppers have high levels of vitamin C, which helps fight free radicals (unstable molecules that can cause cell damage).
Acrylamide is a chemical formed when starchy foods such as potatoes are cooked at high temperatures (above 248°F) for long periods of time (15 minutes or more). Acrylamide has been shown to cause cancer in animals when
Antioxidants are substances that protect the body from damage caused by free radicals. Free radicals are unstable molecules that can travel through the bloodstream and cause damage to cells. Antioxidants bind up these free radicals, making them less likely to cause damage to healthy cells.
The best sources of antioxidants are fruits and vegetables. Some vegetables contain more antioxidants than others. For example, dark leafy greens such as spinach, kale and collards contain large amounts of antioxidants compared to lighter colored vegetables like carrots or tomatoes.
There are two types of antioxidants:
Vitamin A: Found in many fruits and vegetables, vitamin A helps protect your eyes from damage caused by free radicals. The highest sources of vitamin A include carrots, sweet potatoes and butternut squash.
Vitamin C: Also found in many fruits and vegetables, vitamin C helps protect your body against infections by keeping your immune system strong. The highest sources of vitamin C include broccoli and bell peppers.
Antioxidants can be found in many different foods. Some of the richest sources of antioxidants include:
Blueberries
Grapefruit
Spinach
Broccoli
Bell peppers (red and green)
Tomatoes
Strawberries
Kale and other leafy greens
Antioxidants are substances that can be found in plants, fruits, seeds and grains. They can prevent damage to healthy cells by reducing the activity of free radicals. Free radicals are unstable molecules that can damage cells and cause cell death.
Free radicals can be formed as a result of normal body processes such as breathing, digestion, exercising and even thinking! But they can also be formed by external factors such as pollution, cigarette smoke and radiation from the sun.
Antioxidants have been shown to have many health benefits including reducing the risk of certain cancers, heart disease and dementia. For this reason it is recommended that you include a variety of antioxidant-rich foods in your diet every day.
