Low-fat soymilk BNI - 2011
Perezgonzalez re-assessed the nutritional balance of low-fat soymilk 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, low-fat soymilk has, on average, a nutritional balance of BNI 26.77s4, being particularly unbalanced towards excess of sugar. The average low-fat soymilk is also adequate in fat and fiber, low in saturated fat, high in protein and sodium, and low in carbohydrate. It also provides about 119mg of calcium per 100ml.
Low-fat soymilk appears as slightly unbalanced according to international Recommended Dietary Intakes (RDIs), although it is very close to balance according to U.S. and Canada's standards, which allow for a higher content of sugars and fat.

Correlations between indexes are positive, and tend be high between pairs of international indexes, except, perhaps, for the US/CAN index.

The original research was an exploratory study for describing the nutritional balance of milk alternatives in New Zealand in 2011. It was a follow up of a similar study done in 20081.
The initial research sample included 34 alternative milk products (ie, soymilk. ricemilk and oatmilk)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 low-fat soymilk products within the original sample: ie, 10 brands of low-fat soymilk.
Materials & analysis
Alternative milk products were purchased from local supermarket chains in Palmerston North, New Zealand. Nutrition information for each milk product was retrieved from the nutritional 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.
Most of the products are made internationally, especially in Australia. Thus, the results of this study may be generalizable to the following populations (in order of decreasing generalization power):
- Internationally, if one assumes milk alternatives to be of approximately similar nutritional composition anywhere.
