The 2010 dietary guidelines are a month late but aren’t expected to be a fruit and vegetable serving short.

The U.S. Department of Agriculture and the Department of Health and Human Services plan to release the new guidelines Jan. 31 in a teleconference with Agriculture Secretary Tom Vilsack and HHS Secretary Kathleen Sebelius.

The dietary guidelines are reviewed and updated every five years as required by law. The document gives the government’s best science-based advice to Americans to reduce the risk of disease and to optimize health.

No significant change to the fruits and vegetables dietary recommendation is anticipated, said Elizabeth Pivonka, president of the Hockessin, Del.-based Produce for Better Health Foundation.

The government’s dietary guidelines recommended five to nine daily servings of fruits and vegetables in the 1990, 1995 and 2000 dietary guidelines, but expanded that to as many as 13 servings in 2005.

“I think the serving recommendations will stay the same (as 2005),” she said.

Pivonka said the dietary guidelines advisory committee issued a report in 2010 that focused on environmental and policy changes, which may be difficult to incorporate into the new guidelines.

However, Pivonka said the new dietary guidelines may emphasize categories or subcategories of fruits and vegetable to a greater degree.

“In the past they said eat more dark green or deep yellow vegetables and I’m curious to see if they will be more specific than that,” Pivonka said.
