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 […]

Fisetin neuroprotective against Huntington’s disease

Salk.edu – Fisetin, a natural phytochemical found in strawberries and other fruits and vegetables, slows the onset of motor problems and delays death in three models of Huntington’s disease, according to researchers at the Salk Institute for Biological Studies. The study, published in the online edition of Human Molecular Genetics, sets the stage for further investigations into fisetin’s neuroprotective properties […]

Blueberries fight atherosclerosis, increase antioxidant enzymes

USDA.gov – Blueberries may help fight atherosclerosis, also known as hardening of the arteries, according to results of a preliminary U.S. Department of Agriculture (USDA)-funded study with laboratory mice. The research provides the first direct evidence that blueberries – rich in polyphenols – can help prevent harmful plaques or lesions, symptomatic of atherosclerosis, from increasing in size in […]

Sorghum bran higher in antioxidant polyphenols than blueberries, pomegranates

UGA.edu – Select varieties of sorghum bran have greater antioxidant and anti-inflammatory properties than well-known foods such as blueberries and pomegranates, according to a new study from the University of Georgia. Researchers measured polyphenolic compounds, which naturally occur in plants to help fight against pests and disease, and found that the black and sumac varieties of sorghum have significant […]

Polyphenols from Concord grape juice may improve memory in seniors

As America’s baby boomers continue to age, the number of people 65 years of age and older is expected to double to 70 million by 2030. As such, age-related cognitive decline and incidence of chronic conditions, including Alzheimer’s, heart disease, diabetes and cancer, is on the rise. Research supports that good nutrition – particularly a […]

Pycnogenol lowers blood sugar, LDL, and blood pressure in type 2 diabetics

Natural antioxidant pycnogenol in moderate doses improved blood sugar and reduced blood pressure medications. A new study published in the May 2008 (volume 8, issue 25) edition of the journal of Nutrition Research shows Pycnogenol (pic-noj-en-all), an antioxidant plant extract (high in polyphenols) from the bark of the French maritime pine tree, reduces blood sugar in type […]

Green tea polyphenols counteract neurotoxic effects of sleep apnea

Researchers examined the effects of green tea polyphenols (GTP), administered through drinking water, on rats who were intermittently deprived of oxygen during 12-hour “night” cycles, mimicking the intermittent hypoxia (IH) that humans with obstructive sleep apnea experience. People with obstructive sleep apnea have been reported to have increased markers of oxidative stress and exhibit architectural […]
