Abstract
This investigation follows seminal work on nutrient degradation as the
authors seek to quantify how much vitamin C, as a marker of nutrient
quality, is retained at various stages of processing (frozen, steamed, trayline
and delivery) of peas at two New Jersey hospitals. Healthcare providers use
nutrient data standards provided by various national and international gov-
ernment and nongovernment agencies. Physicians, dietitians and menu plan-
ners rely on these values for nutritional therapy. We found that the current
methodology for predicting nutritional outcomes of cooked foods in hospi-
tals may not be reliable in assessing nutrients served to patients. Sampled
peas were found to contain significantly (P < 0.05 for both Hospitals A and
B) less vitamin C compared with the published standard value (‘cooked’) for
vitamin C. In Hospitals A and B, the nutrient quality of vitamin C was
significantly reduced (P < 0.05) as peas progressed to patients. As improved
nutritional status has been shown to correlate with faster healing and recov-
ery, thus reduced hospital stays, we recommend that hospitals use improved
cooking methods to reduce the loss of nutrients in foods served to patients.
Vegetables in particular should be cooked for the briefest period of time or
at the lowest temperature that ensures safety.
Introduction
Hospital dietary professionals routinely use pub-
lished standards directly, or indirectly through
vendor software, as a predictor of nutrition in
foods served to patients. A therapeutic dietary
regimen is presumably obtained, through the con-
sumption of meals based on nutrient reference
databases. Nutrient data standards provided by
various national and international government
and nongovernment agencies are used directly by
healthcare providers or through vended software
packages. These include the Souci-Fachmann-
Kraut (2005) nutrition database in Germany,
Health Canada’s (2005) Canadian Nutrient File,
and the United States Department of Agriculture
(USDA 2006) National Nutrient Database for
Standard Reference, which use comparable nutri-
ent reference values. Physicians, dietitians and
menu planners worldwide rely on these or similar
databases for nutritional therapy. The ascribed
nutrient values, however, do not take into account
the handling, holding and delivery methods that
vary compared with the published models of a
cooked, finished, product. Nutrient data stan-
dards were ostensibly derived from experiments
