Rice cravers' BNI (description)

Perezgonzalez assessed the nutritional balance of rice cravers3 in 20121, as part of a research on the nutritional composition of snacks in New Zealand. This article provides descriptive information both about the sample of products under research (foodBNI) as well as about a hypothetical diet based on those products (dietBNI).

The distribution of nutritional balance, as shown in illustration 1, was rather flat, due to the small number of products under research. The median was located at BNI 60.60 and the middle 68% of products ranged between BNI 42 (P16) and BNI 74 (P84). There was a slight positive skewness (mean=60.77, zSkew=1.59), although, given the size of the sample and the shape of the distribution, this may be of little practical importance.

The distribution of nutritional balance varied slightly according to the particular recommended dietary intakes (RDIs) of reference, although all followed a pattern similar to the one just described. Even so, this group of products appeared slightly less unbalanced under US' and WHO's RDIs than under UK's and Australia's RDIs.

Correlations between indexes were high, thus supporting the idea of a common pattern in the distribution of nutritional balance across international indexes for this particular group of products.

As part of a hypothetical diet where all products contributed the same weight of cravers, the resulting nutritional unbalance would remain practically the same for all indexes (when attending to the unstandardized effect size for this group).
