Nutritional balance of semi-skimmed milk
This article offers descriptive data regarding the nutritional balance of semi-skimmed milk. These data were collected for a research on milk and milk alternatives in New Zealand between 2007 and 2008 (Perezgonzalez, 20081).
Semi-skimmed (semi-skim, light, lite, or reduced fat) milk is defined as that containing about 1.7% fat. This article, however, analyzes the nutritional balance of semi-skimmed milk beyond its fat content. Indeed, the average semi-skimmed milk (in this sample) is adequate in fat but high in saturated fat, high in protein, low in carbohydrate but high in sugar4, low in fiber, and within maximum recommended limits for sodium.
On average, semi-skimmed milk has a nutritional balance of BNI 96.37s, being particularly unbalanced towards excess of sugar.
Semi-skimmed milk appears as highly 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.

Correlations between indexes are high and positive (and significant at the 0.10 cut-off point, which seems appropriate given the small sample size). These correlations indicate that the semi-skimmed milk products being compared tend to form a similar hierarchy when indexed using different international standards.
