Nutritional balance of sugary chocolates
The nutritional balance of sugary chocolates was studied by Pérezgonzález in 20111. He found that a sample of chocolate bars, chocolate blocks and bonbons currently available in New Zealand shared a similar nutritional profile characterized as being low in protein, high in fat, high in saturated fat, low in fiber and low in sodium (Pérezgonzález, 2011b2). Chocolates with extra source of sugars (eg, added caramel) differed from other chocolates in also being high in sugars and high in carbohydrate (see profile in illustration 2).
On average, sugary chocolates have a nutritional balance of BNI 128.26s, being particularly unbalanced towards excess of sugars.
Sugary chocolates show small changes in their indexing across different international Recommended Dietary Intakes (RDIs), with the US/CAN index showing the largest discrepancies, namely because US/CAN standards allow for more sugars to be consumed (see illustration 3). Overall, however, all nutritional indexes are high and relatively similar to each other, which indicates that the nutritional composition of sugary chocolates would be deemed highly unbalanced in different countries.

|Perky Nana mighty||Cadbury||102.96||102.96||72.96||102.96||98.96|
|Whittaker's rum & raisins||Whittaker's||132.64||132.64||102.64||132.64||128.64|
|M&M's milk chocolate||Mars||140.53||140.53||110.53||140.53||136.53|
Correlations between indexes are also perfect and statistically significant. This suggests that the nutritional balance reported by the BNI™ index matches that of other nutritional standards. (Said otherwise, that sugary chocolates and bonbons tend to form a similar hierarchy when indexed using different international standards).

- The initial sample comprised 50 chocolate bars, chocolate blocks and bonbons normally sold around New Zealand (yet most chocolates were manufactured in Australia and, thus, can be assumed they were equally available there, while some were imported from other international locations). The sample almost represented the entire population of chocolates sold at supermarkets in 2011. Yet, for practical reasons, it should be considered as a convenient sample in its collation.
- 7 chocolates shared a particular nutritional profile and, thus, conformed the 'Sugary chocolate subsample' whose results are described here.
Materials & analysis
- Nutrition information for each chocolate was retrieved from the nutritional information panel on each item and was analyzed using the Balance Nutrition Index™ (BNI™) technology (see Pérezgonzález, 2011c3).
- SPSS-v16 was used for statistical analysis, which included descriptives and correlations.
