Observational Studies Link Obesity and Cancer
A 2007 World Cancer Research Fund and American Institute for Cancer Research report calls the data “convincing,” according to an article in the Los Angeles Times.

Vitamin D Is Lacking in Babies
A study in Pediatrics points to the importance of supplementation in infants, reports a Health.com article posted on the CNN Web site.

Winter’s icy hand touched many parts of the country more dramatically than ever this year and covered some cities in record snowfalls. If you live on the East Coast, the arrival of spring may seem even sweeter than usual. Like me, you’re probably looking forward to the beauty and bounty that warmer weather brings. I can’t wait to head down to my friendly neighborhood orchard to sample the first fresh offerings and later to pick strawberries and blueberries—the makings of succulent snacking.

As nutrition professionals, you’re no doubt well aware of berries’ benefits, but are you up on the research investigating the fruits’ disease-preventing properties? Take a look at the evidence in this edition’s E-News Exclusive, which summarizes the research on the polyphenols from berries.

Our April print issue offers antioxidant content aplenty, including the baby boomer generation’s interest in supplemental and dietary forms of antioxidants and the use of antioxidants during cancer therapy.

Enjoy the season, and be sure to visit Today’s Dietitian on Facebook!

With Polyphenols Aplenty, Berries May Protect From Disease
By Maria Frye

Revered for their dessertlike qualities, edible berries have been part of the human diet for centuries. Romans grew the ancestor of strawberries, which later crossed with varieties in America and Chile around 1750. Europeans have cultivated raspberries since the Middle Ages, and man might have consumed blackberries since the Neolithic Era.

While we have satisfied our palates with these delicious fruits for hundreds of years, researchers have recently started recognizing berries’ health properties, including their phytochemical content. Common berry fruits such as black and red raspberries, blackberries, blueberries, and strawberries are rich sources of phytochemicals, especially the polyphenols or phenolic compounds. Berries are particularly plentiful sources of polyphenols, including flavonoids such as anthocyanins and flavonols, as well as ellagitannins.

Researchers have studied these polyphenols from berries in vitro and in rats and humans. Although epidemiological research has not consistently demonstrated the benefits of these phytochemicals from berries, research in vitro and on rodents have been favorable in revealing how these fruits may provide protection from disease.

Kidney Disease Hides in People With Undiagnosed Diabetes

Millions of Americans may have chronic kidney disease (CKD) and not know it, according to a study appearing in the Clinical Journal of the American Society of Nephrology.

“Our research indicates that much of the CKD burden in the United States is in persons with prediabetes and undiagnosed diabetes who are not being screened for CKD,” says Laura C. Plantinga, ScM, of the University of California, San Francisco. The researchers believe broader screening may be needed to detect patients with these two “relatively silent yet harmful diseases.”
