Nutritional balance of rice milk
This article offers descriptive data regarding the nutritional balance of (standard) rice milk. These data were collected for a research on milk and milk alternatives in New Zealand between 2007 and 2008 (Perezgonzalez, 20081).
Rice milk is made from rice and water. The average rice milk (in this sample) is low in protein, high in carbohydrate and sugar, low in fat and saturated fat, low in fiber, and within maximum recommended limits for sodium.
On average, rice milk has a nutritional balance of BNI 42.17s, being particularly unbalanced towards excess of sugar.
Rice milk appears as somehow unbalanced according to international Recommended Dietary Intakes (RDIs), although less so according to U.S. and Canada's standards, which allow for a higher content of sugars and fat.

Correlations between indexes tend to be high and positive (and significant at the 0.10 cut-off point, which seems appropriate given the small sample size), except for the US/CAN index. However, the sample size is too small as for drawing much inference from it.

- The original research was an exploratory study on the nutritional balance of milk and milk alternatives in New Zealand in 2007-2008.
- The initial research sample included 44 milk and alternative milk products (ie, milk, soymilk and rice milk)1. 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 rice milk products within the original sample: ie, 5 brands of rice milk3.
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 nutritional information panel on each item, to be assessed using the Balanced Nutrition Index™ (BNI™) technology (see Perezgonzalez, 20112).
- 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 in Australia and internationally. Thus, the results of this study may be generalizable to the following populations (in order of decreasing generalization power):
- Internationally, if one assumes milk to be of approximately similar nutritional composition anywhere.
