Nutritional balance of cured meats
Perezgonzalez studied the nutritional balance of cured meats in 20111. He found that sandwich-ready cured meats in New Zealand tend to be highly unbalanced, with average BNI values of around 145.09 (foodBNI5). When cured meats are considered as part of a diet (ie, all cured meats are consumed approximately in the same proportion over time), an analysis of average nutrient composition for the aggregated sample becomes relevant and informative. Cured meats thus show an average nutritional balance of BNI 140.91na (dietBNI6), being particularly unbalanced towards excess of sodium. Being an animal-derived product, they are also high in protein, fat and saturated fat, and low in carbohydrate, sugar and fiber (see illustration 2).
Cured meats are highly unbalanced according to international Recommended Dietary Intakes (RDIs), although a bit less so according to the U.S.'s, Canadas's and the U.K.'s standards.

Correlations between indexes tend to be high and positive, indicating that cured meats would be organized in a similar hierarchy of nutritional unbalance by different international standards.
