Brain plays key role in appetite by regulating free radicals

Mon, 11 Aug 2008 15:17:11 +0000

Researchers at Yale School of Medicine have found the brain’s appetite center uses fat for fuel by involving oxygen free radicals—molecules associated with aging and neurodegeneration. The findings, reported in the journal Nature, suggest that antioxidants could play a role in weight control.

Spices may protect against consequences of high blood sugar

Sun, 10 Aug 2008 21:24:07 +0000

Herbs and spices are rich in antioxidants, and a new University of Georgia study suggests they are also potent inhibitors of tissue damage and inflammation caused by high levels of blood sugar. Researchers, whose results appear in the current issue of the Journal of Medicinal Food, tested extracts from 24 common herbs and spices.

Vitamin C injections slow tumor growth in mice

Sun, 10 Aug 2008 21:23:05 +0000

High-dose injections of vitamin C, also known as ascorbate or ascorbic acid, reduced tumor weight and growth rate by about 50 percent in mouse models of brain, ovarian, and pancreatic cancers, researchers from the National Institutes of Health (NIH) report in the August 5, 2008, issue of the Proceedings of the National Academy of Sciences.

Soy compound may halt spread of prostate cancer

Fri, 14 Mar 2008 20:45:16 +0000

A compound found in soybeans almost completely prevented the spread of human prostate cancer in mice, according to a study published in the March 15 issue of Cancer Research, a journal of the American Association for Cancer Research.

Citrus juice, vitamin C give staying power to green tea antioxidants

Wed, 14 Nov 2007 17:17:55 +0000

To get more out of your next cup of tea, just add juice. A study found that citrus juices enable more of green tea’s unique antioxidants to remain after simulated digestion, making the pairing even healthier than previously thought.

New Insights Into How Natural Antioxidants Fight Fat

Sun, 11 Nov 2007 18:17:05 +0000

Scientists in Taiwan are reporting new insights into why diets rich in fruits and vegetables reduce the risk of obesity. Their study focuses on healthful natural antioxidant compounds called flavonoid

Selenium supplements may increase the risk of type 2 diabetes

Sun, 15 Jul 2007 00:55:48 +0000

Selenium, an antioxidant included in multivitamin tablets thought to have a possible protective effect against the development of type 2 diabetes, may actually increase the risk of developing the disease, an analysis by researchers at the University at Buffalo has shown.

Alpha Lipoic acid explored as an anti-aging compound

Sat, 19 May 2007 03:40:43 +0000

Researchers said today they have identified the mechanism of action of lipoic acid, a remarkable compound that in animal experiments appears to slow down the process of aging, improve blood flow, enha

Pomegranate Juice May Help Fight Lung Cancer

Sat, 28 Apr 2007 00:48:04 +0000

Researchers are adding to the list of cancer types for which pomegranates seem to halt growth. A recent study at the University of Wisconsin–Madison using a mouse model shows that consuming pomegran

Antioxidant found in many foods and red wine is potent and selective killer of leukemia cells

Thu, 26 Apr 2007 01:46:14 +0000

A naturally occurring compound found in many fruits and vegetables as well as red wine, selectively kills leukemia cells in culture while showing no discernible toxicity against healthy cells, according to a study by researchers at the University of Pittsburgh School of Medicine.

Blueberries contain chemical that may help prevent colon cancer

Sun, 25 Mar 2007 14:20:06 +0000

A compound found in blueberries shows promise of preventing colon cancer in animals, according to a joint study by scientists at Rutgers University and the U.S. Department of Agriculture. The compound

How Eating Less Might Make You Live Longer

Fri, 16 Mar 2007 14:16:08 +0000

Caloric Restriction in non-obese people translates into less oxidative damage in muscle cells, according to a new study by scientists at Pennington Biomedical Research Center. As oxidative damage has been linked to aging, this could explain how limiting calorie intake without malnutrition extends life span.

Unique tomatoes tops in disease-fighting antioxidants

Wed, 28 Feb 2007 13:32:12 +0000

Deep red tomatoes get their rich color from lycopene, a disease-fighting antioxidant. A new study, however, suggests that a special variety of orange-colored tomatoes provide a different form of lycopene, one that our bodies may more readily use.

Oxidative damage in newly synthesized DNA plays a role in Parkinson’s disease

Tue, 27 Feb 2007 16:04:21 +0000

Oxygen is the quintessential two-edged sword of molecular biology: essential for (animal) life, but at the same time a perennial source of damage to macromolecules. Reactive oxygen species (ROS), arising from both external sources and the intrinsic metabolic machinery of the cell itself, have been implicated in many aspects of cellular aging.

Antioxidants decrease disease in an insect model of Alzheimer’s disease

Sun, 14 Jan 2007 16:00:13 +0000

Alzheimer’s disease (AD) is one of a number of neurodegenerative disorders in which brain cells damaged by naturally occurring chemicals known as reactive oxygen species (ROS) have been observed. However, whether this oxidative damage causes neurodegeneration or is a consequence of it has not been previously determined.
