The Nrf2 knockout scare – can dietary antioxidants hurt you?

A recent UCLA study on the actions of a cellular antioxidant regulator, Nrf2, found that it had some connection to the formation of atherosclerotic plaque, and that reducing Nrf2 decreased atherosclerosis. But should these study findings scare you away from eating Nrf2-promoting dietary antioxidants found in broccoli, blueberries, and dark chocolate, or from taking the […]

Exercise regularly to prevent health problems linked to aging

People who exercise regularly could reduce their risk of developing about two dozen physical and mental health conditions – including some cancers and dementia – and slow down how quickly their body deteriorates as they age. An extensive research review, published in the December 2010 issue of IJCP, the International Journal of Clinical Practice, says that apart from […]

Walking six miles per week prevents memory loss, brain shrinkage

AAN.com – New research suggests that walking at least six miles per week may protect brain size and in turn, preserve memory in old age, according to a study published in the October 13, 2010 online issue of Neurology®, the medical journal of the American Academy of Neurology. “Brain size shrinks in late adulthood, which can cause memory problems. […]

Luteolin fights cognitive decline, brain inflammation

Illinois.edu – A diet rich in the plant compound luteolin reduces age-related inflammation in the brain and related memory deficits by directly inhibiting the release of inflammatory molecules in the brain, researchers report. Luteolin (LOOT-ee-oh-lin), different from lutein, is found in many plants, including carrots, peppers, celery, olive oil, peppermint, rosemary and chamomile, but it is basically not found in high […]

Branched-chain amino acids extend lifespan

When mice are given drinking water laced with a special combination of branched-chain amino acids, they live longer than your average mouse, according to a new report in the October 2010 issue of Cell Metabolism, a Cell Press publication. The key ingredients in the dietary supplement mixture – branched-chain amino acids – account for 3 of the […]

Memory loss linked to high saturated fat diet

Loss of memory with advanced age is a significant problem within most societies, and appears particularly severe in advanced industrialized nations. A less visible and often ignored problem comes from a food supply high in cholesterol and saturated fat, which has led to high obesity rates particularly in the United States. In a study published […]

Activated vitamin D may prevent heart failure

UMich.edu – Vitamin D benefits: strong bones, a healthy immune system, protection against some types of cancer. Recent studies suggest there’s yet another benefit of vitamin D, “the sunshine vitamin.” Vitamin D keeps the heart fit for life’s demands and protects against heart failure. University of Michigan pharmacologist Robert U. Simpson, Ph.D., thinks it’s apt to call vitamin […]

Low vitamin d level increases risk of heart disease

JAMA / Archives – Low levels of vitamin D appear to be associated with higher risk of myocardial infarction (heart attack) in men, according to a report in the June 9, 2008 issue of Archives of Internal Medicine. Studies have shown that the rates of cardiovascular disease-related deaths are increased at higher latitudes and during the winter months […]

Topical phosphatidylserine (PS) fights skin aging, wrinkles

Topical applications of a naturally occurring fat molecule – phosphatidylserine (PS ) – have the potential to slow down skin aging, whether through natural causes or UV damage, researchers report. Through both the normal aging process and external factors like UV damage, smooth, young skin inevitably becomes coarse and wrinkled. The basis of this wrinkling is that time […]
