Skimmed milk BNI - 2011

Perezgonzalez re-assessed the nutritional balance of skimmed milk in 2011², following on the steps of a similar study done in 2008¹. Both data were collected as part of a research on the nutritional balance of milk and milk alternatives in New Zealand.

In 2011, skimmed cow milk had, on average, a nutritional balance of BNI 122.85s⁴, being particularly unbalanced towards excess of sugar. The average skimmed cow milk was also adequate in total carbohydrates, low in saturated fat, high in protein and sodium, and low in fat and fiber. It also provided about 147mg of calcium per 100ml.

International standards

Skimmed milk appeared as extremely unbalanced according to international Recommended Dietary Intakes (RDIs).

Methods

Research approach

The original research was an exploratory study for describing the nutritional balance of milk in New Zealand in 2011. It was a follow-up of a similar study done in 2008¹.

Sample

The initial research sample included 68 milk products (ie, standard, semi-skimmed, skimmed, and flavored)². The food products were collected in a convenient manner, looking more for a variety of brands than a random sampling of the same. The results in this study simply describe the 'subsample' of skimmed cow milk products within the original sample: ie, 18 brands of skimmed milk.

Materials & analysis

Milk products were purchased from local supermarket chains in Palmerston North, New Zealand. Nutrition information for each milk product was retrieved from the nutrition information panel on each item, to be assessed using the Balanced Nutrition Index™ (BNI™) technology (see Perezgonzalez, 2011b³). SPSS-v16 was used for variable computations, including BNI and international indexes, and statistical analysis, which included descriptives and correlations.

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 milk products to be of approximately similar nutritional composition anywhere.
