Scientists are reporting development of a nano-size capsule that boosts the body's uptake of curcumin, an ingredient in yellow curry now being evaluated in clinical trials for treatment of several diseases. Their study is in ACS' Journal of Agricultural and Food Chemistry, a bi-weekly publication. Koji Wada and colleagues note that curcumin is a potent antioxidant found in the spice, turmeric. Clinical trials are checking its safety and effectiveness for colon cancer, psoriasis, and...

Scientists said on Wednesday that a molecule found in a curry ingredient kills esophageal cancer cells in the laboratory, suggesting it might be developed as an anti-cancer treatment, Reuters reported. Curcumin, a chemical found in the spice turmeric, gives curries a distinctive yellow color, but researchers at the Cork Cancer Research Center in Ireland used it to treat esophageal cancer cells and found it started to kill cancer cells within 24 hours. According to the study published in the...

Natural compound in extra-virgin olive oil targets toxic beta-amyloid proteins Oleocanthal, a naturally-occurring compound found in extra-virgin olive oil, alters the structure of neurotoxic proteins believed to contribute to the debilitating effects of Alzheimer's disease. This structural change impedes the proteins' ability to damage brain nerve cells. "The findings may help identify effective preventative measures and lead to improved therapeutics in the fight against Alzheimer's disease,"...

A healthy alternative to sugary snacks -- raisins -- may actually prevent tooth damage, U.S. researchers say. In addition to the polyphenols, flavonoids and iron in raisins, U.S. researchers also found germ-fighters that may suppress tooth disease. One of the many antimicrobial phytochemicals found in raisins -- oleanolic acid -- has been shown to suppress the tooth disease-causing Streptococcus mutans biofilm. Grape seed extract, high in proanthocyanidins, has been found to positively...

Ascorbic acid and sugar added to green tea can help the body absorb helpful catechins found in the tea, U.S. researchers said. Mario Ferruzzi of Purdue University adapted a digestion model with human intestinal cells to show that adding ascorbic acid -- vitamin C -- to green tea would increase the absorbability of catechins found in the tea. Catechins -- a class of polyphenols common in tea, cocoa and grape -- are anti-oxidants thought to fight heart disease, stroke, cancer, diabetes and...

The antioxidant quercetin is increasingly being marketed as a supplement that boosts athletic performance, but a new University of Georgia study finds that it is no better than a placebo. Professor Kirk Cureton, head of the department of kinesiology in the UGA College of Education, and his colleagues tested quercetin in a double-blind, placebo-controlled study that assessed a variety of measures, including the ability of muscles to synthesize energy, cycling performance, perceived exertion...

An international team of scientists has found that the polyphenol content of fruits has been underestimated.Polyphenol content in fruits usually refers to extractable polyphenols, but a Spanish scientist working at the Institute of Food Research in Norwich analysed apple, peach and nectarine. She found that nonextractable polyphenol content is up to five times higher than extractable compounds. This work has been published in the Journal of Agricultural and Food Chemistry."These polyphenols...

Popcorn and many breakfast cereals contain surprisingly large amounts of the antioxidant polyphenols, believed to reduce disease, U.S. researchers said. Study leader Joe Vinson of the University of Scranton in Pennsylvania said polyphenols are a major reason why fruits, vegetables, chocolate, wine, coffee and tea have become known for their potential role in reducing the risk of heart disease, cancer and other diseases. Commercial hot and cold whole grain cereals have been regarded as...

 The polyphenols found in red wine are thought to help prevent Alzheimer's disease, and new research from Purdue University and Mount Sinai School of Medicine has shown that some of those compounds in fact reach the brain.Mario Ferruzzi, a Purdue associate professor of food science; Connie Weaver, Purdue's head of foods and nutrition; and Elsa Janle, a Purdue associate professor of foods and nutrition, found that the amount of polyphenols from grapeseed extract that can reach a rat's...
