In a laboratory experiment using a between-subjects design, the authors examine the effects
on nutrition and product evaluations of nutrition claims made (e.g., "99% fat free; " "low in
calories") on a product package, product nutrition value levels, and enduring motivation to
process nutrition information. Enduring motivation is shown to moderate the effects of
product nutrition value on consumer evaluations. Also, nutrition claims interact with
product nutrition value in affecting consumer perceptions of manufacturer credibility. Given
the availability of nutrient levels in the Nutrition Facts panel on the back of the mock
package, nutrition claims on the front of the package generally did not affect positively
consumers' overall product and purchase intention evaluations. The authors discuss some
implications of these findings, suggestions for further research, and study limitations. I
