Special journal issue focuses on beverages and health
WEST LAFAYETTE, Ind. - Purdue University health researchers are partnering with other experts to better understand the role that beverages, such as sweetened, dairy, alcoholic and caffeinated drinks, play in the daily diet.
"People consume beverages for a number of reasons - quenching thirst, fueling the body with nutrients or enjoyment," said Richard D. Mattes, Purdue professor of foods and nutrition. "There are benefits, such as providing essential nutrients, and there are risks, such as taking in unneeded energy. We strive to find a balance and a better understanding, especially as our nation struggles with an obesity epidemic."
A series of articles are featured in the Physiology & Behavior journal's special issue Beverages and Health that was published last month. The researchers focused on caffeinated, sweetened, dairy, alcoholic and meal-replacement beverages.
The articles were presented and discussed at the Ingestive Behavior Research Center international symposium in September 2009. The center, which is housed at Purdue, promotes the interdisciplinary study of the controls and consequences of ingestive behavior.
"A better understanding of the relative benefits and concerns related to beverage consumption should aid the development of rational clinical and public health policies to educate and guide consumers toward healthful food choices," said Mattes, who also edited the journal's special issue. "The issues are complex as all beverages help with hydration, many provide important nutrients, such as calcium and protein, and some are sources of promising phytochemicals. So beverages may mitigate prevalent disorders such as osteoporosis, sarcopenia and certain cancers while, at the same time, many contribute energy to a population struggling with being overweight and obesity. Finding the most healthful balance should be our goal and was the motivation for the symposium."
