Antioxidants are substances that protect cells from the damage caused by free radicals (unstable molecules made by the process of oxidation during normal metabolism). Free radicals may play a part in cancer, heart disease, stroke, and other diseases of aging. Antioxidants include beta-carotene, lycopene, vitamins A, C, and E, and other natural and manufactured substances.

Study sheds light on long-hidden link between chronic high blood sugar and disruption of mitochondria

Study sheds light on long-hidden link between chronic high blood sugar and disruption of mitochondria

Scientists at Johns Hopkins say they've discovered a cause-and-effect link between chronic high blood sugar and disruption of mitochondria, the powerhouses that create the metabolic energy that runs living cells. The discovery, reported online in Proceedings of the National Academy of Sciences on April 27, sheds light on a long-hidden connection and, they say, could eventually lead to new ways of preventing and treating diabetes.

Lettuce varieties can have different antioxidant effect

Lettuce, one of the indispensable vegetables in the Mediterranean diet, is a food that greatly benefits health, mainly because it is rich in antioxidants. But not all lettuce varieties have the same antioxidant effect. [More]
New research finds link between milk consumption and high levels of glutathione in the brain

New research finds link between milk consumption and high levels of glutathione in the brain

New research conducted at the University of Kansas Medical Center has found a correlation between milk consumption and the levels of a naturally-occurring antioxidant called glutathione in the brain in older, healthy adults. [More]

Loyola ophthalmologist recommends specific foods and supplements for healthy vision

You may remember your mother telling you to eat your carrots; they are good for your eyes. Well, she was right. "Carrots are actually just one of the many foods, and supplements that contribute to good eye health," says James McDonnell, MD, pediatric ophthalmologist, Loyola University Health System. "In some cases, eyesight can actually be improved depending on what you eat." [More]

Exposure to diesel exhaust may exacerbate respiratory diseases

Exposure to diesel exhaust may exacerbate respiratory diseases

Researchers in the UK have, for the first time, shown how exhaust pollution from diesel engines is able to affect nerves within the lung. Air pollution is a significant threat to health, they say, and identifying potential mechanisms linking exposure to diesel exhaust and the exacerbation of respiratory diseases may lead to treatments for those affected.

High levels of triglycerides, cholesterol can keep vitamin E tied up in blood stream

High levels of triglycerides, cholesterol can keep vitamin E tied up in blood stream

In the continuing debate over how much vitamin E is enough, a new study has found that high levels of blood lipids such as cholesterol and triglycerides can keep this essential micronutrient tied up in the blood stream, and prevent vitamin E from reaching the tissues that need it. [More]
Consuming popular dietary supplement ubiquinone unlikely to provide any benefit

Consuming popular dietary supplement ubiquinone unlikely to provide any benefit

The popular dietary supplement ubiquinone, also known as Coenzyme Q10, is widely believed to function as an antioxidant, protecting cells against damage from free radicals. But a new study by scientists at McGill University finds that ubiquinone is not a crucial antioxidant -- and that consuming it is unlikely to provide any benefit. [More]

Discovery demonstrates effect of exercise to prevent chronic health conditions

Discovery demonstrates effect of exercise to prevent chronic health conditions

A researcher at the University of Virginia School of Medicine has magnified a benefit of exercise in mice to provide a "profound" protection from diabetic cardiomyopathy, a potentially deadly heart condition that affects many people with diabetes. The discovery demonstrates the power of exercise to prevent chronic health conditions and suggests that one day some benefits of exercise may come in a pill or bottle. [More]
