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.
