Yak milk BNI

Perezgonzalez assessed the nutritional balance of yak milk as for human consumption in 2012. Results were based on data published by Medhammar et al (20111).

Yak milk had, on average, a nutritional balance of BNI 83.95f, being particularly biased towards excess of fat. It was adequate in protein and sodium, low in carbohydrate and fiber, and high in sugar and saturated fat. It also provided about 129mg of calcium per 100ml of milk.

Methods

Research approach

Exploratory study.

Data

Collated from Medhammar et al (20111).

Materials & analysis

Relevant data were collated, then assessed using the Balanced Nutrition Index™ (BNI™) technology (see Perezgonzalez, 2011b3). SPSS-v16 was used for the computation of variables, including BNI and international indexes, and statistical analyses.

Generalization potential

Medhammar et al's (20111) data were based on international research. Thus, these results are also generalisable internationally.
