BNI of generic brands (description)
Some potato chips5 are sold under a generic brand (eg, a supermarket brand) while others are sold under proprietary brands, with the latter having a somewhat better standing in regards to perceived quality. Thus, it is of interest to test whether such characteristic informs about overall nutritional balance (BNI) and, thus, whether it may help choose more balanced products. As part of his research on the nutritional balance of potato chips, Perezgonzalez (2012)3 also assessed whether generic and proprietary brands differed in regards to overall nutritional balance. 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).
Proprietary brands were more abundant than generic brands, overall. Even so, the distribution of nutritional balance in the two groups was quite similar: they appeared as highly unbalanced6, clustering around BNI 80 and with their medians located at around BNI 827. They also showed a perceptible skewness towards higher levels of unbalance, with means located around BNI 86. Indeed, the 68% of generic products in the middle of the distribution had a nutritional balance somewhere between BNI 79.58 (P16) and BNI 98.29 (P84), while the middle 68% of named products had a nutritional balance somewhere between BNI 79.41 (P16) and BNI 98.62 (P84). In both cases the means were off-centered towards the 84th percentile.

As part of two hypothetical diets where the corresponding generic and named products contributed the same weight of chips, the resulting nutritional composition of such diets would still be highly unbalanced, of around BNI 70 for both diets.

Exploratory study for mapping the nutritional balance of potato chip products5 sold under generic and proprietary brands in New Zealand.
Stratified sample of 63 potato chip products (Perezgonzalez, 2012a2), including diverse flavors and other relevant categories. Of these products, 15 were from generic brands and 48 were from proprietary brands. The products were collected in a convenient manner from three major national supermarket chains. The final sample covered a large proportion of the population of potato chip products available in such supermarkets.

Variables of interest for this research were the following:
- Weight contribution of seven nutrients (protein, carbohydrate, sugar, fat, saturated fat, fiber and sodium) to 100g of a food product.
- The Balanced Nutrition Index (BNI) of each food product, as calculated from above variables.
- Aggregated information for the sample of products (foodBNI).
- Aggregated information about the individual nutrients for the simulation of a potato-chip-based diet (dietBNI).
Materials & analysis
Relevant data were collated after purchasing the food products or by capturing such information from the producers' websites if this information was available and was deemed reliable. The data were then assessed using the Balanced Nutrition Index™ (BNI™) technology (see Perezgonzalez, 20111). Missing data for fiber was estimated from USDA's database (20114).
SPSS-v18 was used for the computation of the BNI, and for descriptive statistical analyses.
