Antioxidant News and Research

RSS

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.

Citrus fruits may keep stroke at bay for women

In the study published last Thursday in Stroke, a journal of the American Heart Association, researchers analyzed the flavonoid intake of 69,622 women from the U.S.-based Nurses’ Health Study, which has followed nurses since 1976 to assess risk factors for cardiovascular disease and cancer. The total flavonoid intake of the 69,622 women was calculated after they completed food intake questionnaires collected every four years using a U.S. Department of Agriculture database. They found that during 14 years of follow up surveys beginning in 1990, 1,803 incidents of strokes were confirmed from the women.

Exposure to metformin may decrease risk of cancer

In 2005, news first broke that researchers in Scotland found unexpectedly low rates of cancer among diabetics taking metformin, a drug commonly prescribed to patients with Type II diabetes. Many follow-up studies reported similar findings, some suggesting as much as a 50-per-cent reduction in risk.

Ethanol, nonalcoholic compounds in red wine may reduce risk of vascular disease

Observational epidemiologic studies relating wine and alcohol to health all suffer from the fact that they, of necessity, compare people who prefer certain beverages, but not the beverages themselves. While there have been many intervention trials in animals, randomized trials in humans are less common. Randomized crossover trials, in which each subject receives all interventions in sequence, can be especially important as they tend to avoid baseline differences among subjects and can detect effects of different interventions with smaller numbers of subjects.

Grapes offer dramatic protection against age-related macular degeneration

Can eating grapes slow or help prevent the onset of age-related macular degeneration (AMD), a debilitating condition affecting millions of elderly people worldwide? Results from a new study published in Free Radical Biology and Medicine suggest this might be the case. The antioxidant actions of grapes are believed to be responsible for these protective effects.

Mitochondrial dysfunction in tissue stem cells can cause aging-associated degeneration

Aging-related tissue degeneration can be caused by mitochondrial dysfunction in tissue stem cells. The research group of Professor Anu Suomalainen Wartiovaara at the University of Helsinki, with their collaborators in Max Planck Institute for Biology of Aging, Karolinska Institutet and University of Wisconsin, reported on the 3rd January in Cell Metabolism their results on mechanisms of aging-associated degeneration.

Healthy diet keeps the brain sharp

The study shows that elderly who followed this diet had less of the brain shrinkage linked with Alzheimer's disease and scored better on mental and thinking tests than those with poorer diets. Although previous studies have suggested that a heart-healthy diet is also good for the brain, the new study took a different approach by using blood tests to determine the participant’s diet and nutrient levels.

Poor handling of oranges in squeezing machines stimulates bacterial contamination

Scientists from the University of Valencia in Spain have analysed fresh orange juice squeezed by machines in catering establishments. They have confirmed that 43% of samples exceeded the acceptable enterobacteriaceae levels laid down by legislation. The researchers recommend that oranges are handled correctly, that juicers are washed properly and that the orange juice is served immediately rather than being stored in metal jugs.

Antioxidant can delay onset of all indicators of Alzheimer's

When you cut an apple and leave it out, it turns brown. Squeeze the apple with lemon juice, an antioxidant, and the process slows down. Simply put, that same "browning" process-known as oxidative stress-happens in the brain as Alzheimer's disease sets in. The underlying cause is believed to be improper processing of a protein associated with the creation of free radicals that cause oxidative stress.
