Standard natural yogurt's BNI

Perezgonzalez assessed the nutritional balance of standard natural yogurt in 2011, as part of a research on yogurts in New Zealand.

Standard natural yogurt had, on average, a nutritional balance of BNI 67.50s, being particularly biased towards excess of sugar. It was adequate in protein and sodium, high in fat and saturated fat, and low in carbohydrate and fiber. It also provided about 163mg of calcium per 100g of yogurt.

International standards

Standard natural yogurt appeared as highly unbalanced according to international Recommended Dietary Intakes (RDIs), although only as moderately unbalanced according to US/CAN standards.

Methods

Research approach

Exploratory study.

Data

The initial research sample included 342 yogurt products (ie, cow-milk and soy, natural and flavored, and fat-free, low-fat, standard and creamy)1. The sample was collected in a convenient manner, looking more for a large sample than a random selection of products. The results in this study simply describe the 'subsample' of standard natural cow-milk yogurts within the original sample: ie, 10 products.

Materials & analysis

Relevant data were collated, then assessed using the Balanced Nutrition Index™ (BNI™) technology (see Perezgonzalez, 2011b2). SPSS-v18 was used for the computation of variables, including BNI and international indexes, and statistical analyses.

Generalization potential

Most of the products were produced locally, although some may have been imported or exported, especially from and to Australia, respectively. Thus, the results of this study may be generalizable to the following populations (in order of decreasing generalization power):

  • Australia.
  • Internationally, if one assumes yogurt products to be of approximately similar nutritional composition anywhere.
