Distributions of serving sizes and plate waste in school lunches. Implications for measurement.

Distributions of school lunch serving size and plate waste data are discussed in items of implications for plate waste measurement. Mean serving size was a representative measure when based on 10 rather than the 4 or 5 samples typically weighed. Distributions of percent plate waste supported previous findings of L- or U-shaped distributions. Percent waste of a given food was better represented by the proportion of individuals who consumed all or almost all, and none or almost none, of a serving, than by mean percentage of waste.

Measuring individual plate waste in school lunches. Visual estimation and children's ratings vs. actual weighing of plate waste.

Weighing individual plate waste is time consuming and often impractical. As alternatives, two indirect measures were evaluated-visual estimation and children's ratings of plate waste. Visual estimations were highly correlated with percent waste (r = 0.93) and were quite accurate. Ratings by children were less accurate but were still considered a useful indirect measure that should be further developed.
