Chips, crisps & cravers' BNI

This article is a meta-analysis carried out on nine samples of chips⁶, crisps⁷ and cravers⁸ described individually in other articles (see Perezgonzalez, 2012a¹_d⁴) but here combined for the purpose of such meta-analysis.

Chips, crisps and cravers had, on average, a nutritional unbalance of BNI 66.84-fb, being particularly biased towards deficiency in fiber. They were also adequate in carbohydrate and sugar, high in fat, saturated fat and sodium, and low in protein and fiber.

Methods

Research approach

Exploratory study.

Data

The research sample comprised 188 chip, crisp and craver products, including different brands and flavors, collated from previous research after visually ascertaining that they shared a similar nutritional profile (see Perezgonzalez, 2012a¹_d⁴).

Materials & analysis

Relevant data were collated, then assessed using the Balanced Nutrition Index™ (BNI™) technology (see Perezgonzalez, 2012e⁵). SPSS-v18 was used for the computation of variables, including BNI and international indexes, and statistical analyses.
