Antioxidants are substances or nutrients in our foods which can prevent or slow the oxidative damage to our body. When our body cells use oxygen, they naturally produce free radicals (by-products) which can cause damage. Antioxidants are nutritive and non-nutritive substances that can retard or inhibit oxidation and/or neutralize the effects of damaging "free radicals". In humans, oxidative stress is implicated in an ever growing number of chronic diseases including cardiovascular disease and cancer. Antioxidants in foods are a valuable addition to a healthy diet and steps can be taken to preserve the antioxidant content of foods until they are ready to be ingested. Keeping fruits and vegetables refrigerated or in a cool, dry place helps to slow down the natural breakdown by enzymes that begins to occur as soon as the foods are picked.
Antioxidants are also widely used as ingredients in dietary supplements in the hope of maintaining health and preventing diseases such as cancer and coronary heart disease . Although some studies have suggested antioxidant supplements have health benefits, other large clinical trials did not detect any benefit for the formulations tested, and excess supplementation may be harmful. Antioxidant treatment re-established the redox status and prevented oxidative stress-induced renal damage. Antioxidants are substances that protect cells from damage caused by free radicals. Free radicals are highly reactive chemicals formed during normal chemical reactions in the body.
Antioxidant supplements need to be considered medicinal products and should undergo sufficient evaluation before marketing such as the clinically proven supplement. Antioxidants are compounds that protect cells against the damaging effects of reactive oxygen species, such as singlet oxygen, superoxide, peroxyl radicals, hydroxyl radicals and peroxynitrite. An imbalance between antioxidants and reactive oxygen species results in oxidative stress, leading to cellular damage. Antioxidants are substances that may protect cells from the damage caused by unstable molecules known as free radicals. Free radical damage may lead to cancer.
Oxidative stress results from exposure to xenobiotics, which are detoxified by phase I and phase II pathways. These detoxification pathways also operate in the pancreas. Oxidative stress is initiated by free radicals, which seek stability through electron pairing with biological macromolecules such as proteins, lipids and DNA in healthy human cells and cause protein and DNA damage along with lipid peroxidation. These changes contribute to cancer, atherosclerosis, cardiovascular diseases, ageing and inflammatory diseases. Oxidative damage accompanies most, if not all, diseases and has even been proposed as a direct cause of some including lung cancer, atherosclerosis and Alzheimer's.
GLUTATHIONE is one of the body's most potent antioxidants and makes small amounts of it. Low glutathione levels accompany cataract formation.
Flavonoids and phenolic acids are widely distributed in higher plants and form part of the human diet. Recent interest in these substances has strongly been stimulated by the potential health benefits arising from the antioxidant activity of these polyphenolic compounds. Flavonoids in cooked tomatoes are better absorbed than raw tomatoes. We don't know for sure what's happening in the gut, but we do know this is true.".
Although Artichokes are an excellent source of the antioxidant vitamin C, not all antioxidants are created equal. Alkalinization (to make alkaline), used to reduce the acidity and raise the pH of cocoa was found to markedly reduce procyanidin content.
Antioxidant supplements serve as the protective coating; when they are introduced in the body, they gather up the free radicals, preventing them from damaging the cells. Antioxidant supplements are a great help to the body in keeping the free radicals under control so they do not cause considerable damage to the cells.
A food supplement of 22 fruits and vegetables to help to up your 5-A-DAY ORAC units.
Carotenoids are the pigment compounds that give many fruits and vegetables their vibrant colors. Antioxidants are believed to be effective in helping to prevent cancer, heart disease, stroke and a variety of other ailments associated with natural aging. Carotenoids are the red, orange and yellow plant pigments that give fruits and vegetables their vivid colors. All fruits and vegetables contain varying concentrations of carotenoids, but their colors are often covered up by green chlorophyll contained in the plant. Carotenoids are plant based antioxidants. They include beta carotene, lutein and lycopene.
Research shows that grape seed extract may help to prevent or control damage to body cells that is caused by drugs, pollution, tobacco, and other toxins. It also indicates that an important factor in aging is the decay of the mitochondria - the organelles within the cell that convert amino acids, fatty acids and sugars, into energy. As we age, the efficiency of the mitochondria diminishes, as does their quantity per cell.
Free radicals are associated with liver damage due to alcohol and the development of emphysema from cigarette smoking. The body has developed a number of mechanisms to minimize free radical damage and even repair damage. Free radicals are formed when a bond is broken without forming ions. Because of their unpaired electrons, most free radicals are extremely reactive.
Free radicals can be chemically very or they can be very stable (nitric oxide ). Free radicals are the highly unstable chemicals that attack, infiltrate, and injure vital cell structures. Most stable chemical compounds in the body possess a pair of electrons. Free radical chemistry plays a crucial role in important processes that affect the manufacturing industry, the environment, human health and animal health.
Damage by excessive free radicals can be limited or even prevented by anti-oxidants, which can neutralize free radicals. The human body itself produces and contains anti-oxidants to prevent the harmful effects of free radicals if the daily diet is good. Damage can include single-strand breaks, modification of base pairs, and cross-links between strands. If the DNA repair mechanisms are unable to fix the damage, the damaged DNA may contain various mutations that can affect cellular function, and in some cases this leads to carcinogenesis.
Aging bodies can easily convert NAC into the eye-protecting antioxidant glutathione, defending the eye from harmful free radicals and nerve cell damage. Aging bodies can easily convert NAC into the eye-protecting antioxidant glutathione, defending the eye from harmful free radicals. These two key ingredients reduce oxidative damage to retinal cells and thus help protect the eye.
Green tea has less caffeine than black or oolong tea. The amount of caffeine depends on how tea is brewed, how long it's brewed, and what part of the tea plant - the leaf or bud comes from and the size of the leaf when brewed. Green tea is said to diminish fine lines. Lavender oil is a good toner and lemon oil is a good rejuvenator and toner. Green tea extract helps to support normal cholesterol levels, the digestive and respiratory systems, and the health of skin tissue.
Wild blueberry supports the health of the brain, heart, urinary tract, and eyes. Blueberry extract further promotes maintenance of healthy brain, cardiovascular, vision, joint and urinary tract function, and normal glucose levels.
Carnosine is an antioxidant amino acid naturally present in the human body that may delay the natural aging of cells and extend the lifespan of adult stem cells.
Glutathione improves liver detoxification by binding to toxins and neutralising their harmful effects. Glutathione may be helpful in the treatment of liver disease, along with many toxic and infectious conditions. Glutathione peroxidase is also used by the body to consume free peroxide in the cells. Glutathione helps to protect the mitochondria (the cell's energy production unit) and the cell membrane. Glutathione also helps to protect against DNA damage.
Oxidative stress occurs in your body when there are not enough anti-oxidant to counter the effects of the damaging free radicals.
Oxidation is a vital part of life. But as vital as oxidation is, it can also have some negative effects on the body.
Eating the recommended 5 A Day quota of fruits and vegetables is essential to obtain your daily antioxidants quota for good health. However, as most people are not able to achieve the 5-A-DAY portions, antioxidant supreme food supplement is the ideal top-up product.
