A combination treatment of statin and niacin reduced cardiovascular events by 60-90%, reversing plaque buildup in the arteries. Antioxidant vitamins had no significant benefit on cardiovascular outcomes, contrary to previous assumptions.
A new study reveals that cranberries are the top antioxidant in fruits, while fresh berries and white wine can reduce heart disease risk. Cooking techniques like covering food with foil and using lower-protein ingredients can also help achieve a golden brown color and reduced browning.
A new study by the American Chemical Society ranks cranberries number one in antioxidants, making them a key component of a healthy diet and lifestyle. The study found that cranberries contain more disease-fighting phenols than other fruits, including broccoli, which has been shown to have anti-cancer properties.
Researchers describe a new cause of respiratory failure in newborns and report a virulent Beijing strain causing a 'microepidemic' of TB on Gran Canaria Island. Exercise-induced oxidative stress may exacerbate chronic obstructive pulmonary disease, according to studies published in the American Thoracic Society Journal.
A nationwide clinical trial found that a dietary supplement of antioxidants and zinc significantly reduces the risk of advanced age-related macular degeneration (AMD) and its associated vision loss. The supplements reduced the risk of AMD progression by 19% in those with intermediate AMD.
Researchers found that antioxidant treatment produced scattered blistering, lower inflammation, and extensive healing compared to no treatment or acid suppressants. Oxidative damage was a major cause of reflux oesophagitis, suggesting antioxidants should be considered primary treatment alongside acid suppressants.
Research presented at the International Chemical Congress of Pacific Basin Societies found that beer, especially darker ales and stouts, may reduce the incidence of atherosclerosis and cataracts by up to 50 percent. Antioxidants in beer, particularly those found in darker brews, are believed to play a role in this protection.
Researchers from the University of Florida and Washington University in St. Louis have discovered that oxidative stress is involved in kwashiorkor, leading to high levels of free radicals destroying healthy cells. The study suggests giving children antioxidant supplements may help increase their life spans.
A review by Sanjiv Agarwal and Akkinappally Venketeshwer Rao suggests that dietary antioxidants, particularly lycopene found in tomatoes, may have protective effects against cancer. Further research is necessary to establish guidelines for healthy eating and confirm the role of lycopene in disease prevention.
Researchers at Virginia Tech and the University of Cadiz have developed a method to extract antioxidants from grape seeds using carbon dioxide, producing an extract with greater potency without toxic chemicals. The new process takes 25% less time and can be fully automated.
Researchers add antioxidants to plastic wrap, extending beef shelf life by two to three days. Synthetic antioxidants show significant increase, while natural antioxidants have minimal effect.
Researchers have discovered a potent antioxidant in beer, specifically the compound xanthohumol found in hops, which has been shown to be six times more effective than antioxidants in citrus fruits and four times more effective than those in soy products. The study suggests that drinking beer may help prevent certain diseases such as h...
A study published in the American Journal of Clinical Nutrition found that smokers who received vitamin C supplements showed a substantial 3-fold increase in vitamin C levels, while nonsmokers and placebo recipients showed minimal changes. Vitamin C is significantly depleted by smoking, making supplementation beneficial for smokers.
A new study suggests that a diet without vitamins A and E may help cancer patients by reducing the size of brain tumors and inducing oxidant stress in cancer cells. This could lead to improved outcomes for those undergoing chemotherapy or radiation therapy, as antioxidants can prevent cancer cells from self-destructing.
Researchers at UT Southwestern Medical Center discovered that alpha-lipoic acid reduces oxidative stress and blood levels of bad cholesterol. The compound may improve blood-glucose control and has potential implications for aging and heart disease prevention.
A new research study found that animals fed a blueberry extract diet showed fewer age-related motor changes and outperformed their counterparts on memory tests. The antioxidants in blueberries may help protect the body against oxidative stress, a process implicated in aging and neurodegenerative diseases.
Researchers found that melatonin reacts with peroxynitrite-derived free radicals, forming compounds similar to brain signaling chemicals. These metabolites could impact aspects of behavior, such as mood, with unclear consequences for human health.
Researchers found progeria cells have low catalase and glutathione peroxidase activity, making it hard to remove toxic peroxides. Reintroducing these enzymes could halt or reverse the problem using adenovirus gene transfers.
Researchers have determined that a particular enzyme bound to HDL acts as a powerful antioxidant within blood vessels. This discovery may lead to new treatments for heart disease by preventing oxidative modifications of low-density lipoprotein (LDL).
A study of 54 postmenopausal women found that a higher intake of vitamin E from food was linked to reduced oxidation of LDL cholesterol, a key indicator of heart disease. This benefit occurred only in women who did not use supplements.
Researchers found a direct dose-response relationship between alcohol consumption and gum disease severity. Low antioxidant vitamins like selenium increased the risk of gum disease by 13-fold.
Research suggests tart cherries' anthocyanins can prevent oxidative damage and inhibit inflammatory enzymes, rivaling commercial antioxidants like vitamin E. Daily consumption of 20 tart cherries may provide anti-inflammatory benefits for pain relief from arthritis and gout.
Researchers at the University of Pennsylvania School of Medicine have found that vitamin E confers potent protection from atherosclerosis in genetically modified mice. The study demonstrates that free radicals play a central role in heart disease, and the antioxidant action of vitamin E significantly reduces atherosclerotic damage.
Researchers analyzed 19 samples of honey from 14 different floral sources and found that dark buckwheat honey packs 20 times the antioxidant punch as California sage honey. Darker honey has less water and more antioxidants than light-colored honey, making it a potential supplemental source for antioxidants.
A new study suggests that grape pomace can be a rich source of antioxidants, which may help prevent coronary heart disease. The researchers extracted compounds called phenolics from red grape pomace and found them to significantly retard the oxidation of human low-density lipoprotein (LDL) or bad cholesterol.
Researchers found that patients with poor diabetes control had depleted antioxidants, increasing the risk of complications. Taking antioxidant supplements like vitamin C or E may help prevent these complications.
A new study found that consuming high levels of antioxidants like beta carotene, selenium, and vitamins C and E can significantly improve lung function, comparable to the difference between a nonsmoker and a long-term smoker. The research suggests that these antioxidants may help prevent asthma, emphysema, and chronic bronchitis.
Researchers have developed a new test to measure corrosive free-radical activity in individuals, providing insight into antioxidant effectiveness. The test uses an isoprostane marker, IPF2alpha-I, which can be detected in urine, and has been validated through cross-validation with an older assay.
Smoking in French men is associated with reduced vitamin E, C, and carotene intake, as well as altered oxidative stress indexes. This study highlights the importance of public health intervention for smokers in France.
Researchers at University at Buffalo found a miniscule increase in free radicals in the blood reflects lung damage equivalent to 3-5 years of aging. Oxidative stress was also associated with narrowing of pulmonary airways, while bilirubin showed a positive relationship to lung function.
A major European study found that an antioxidant compound called lycopene in tomato sauce appears to have a protective effect against heart attacks. The study showed men with high lycopene consumption had about half the risk of heart attack compared to those with low lycopene consumption.
Cancerous cells produce high amounts of free-radicals that promote uncontrolled cell growth; antioxidants and protein inhibitors can suppress this process, slowing down runaway cell division.
