ticipants were screened to exclude individuals with acute or chronic inflammation and other medical conditions. They were also screened for undernutrition, and protein, iron, vitamin B12 and folate status. Analysis and comparison of blood samples from the generally healthy and well-nourished older and young participants showed "most immune parameters were not compromised with aging."

"These findings highlight the importance of simultaneous examination of health and nutritional status in studies of immune function with aging," the researchers write.

In conclusion, the authors add that nutritional status should also be evaluated in conjunction with defining a person's health status and that future studies are needed to examine the interaction of specific nutrients with aging and immune response.

The study was supported by grants from the U.S. Department of Agriculture and the National Cattlemen's Beef Association.
