Health claims and the BNI of yogurts

Health-related claims are commonly used when marketing yogurts. As many of these claims cannot be legally made unless products meet such claims, it is of little interest to test the truth of individual claims. However, it is of interest to test whether such claims inform about overall nutritional balance (BNI). This way, a consumer may rely on any significant claim for choosing more balanced products. This article summarizes research done in this regards (for an in-depth description see Perezgonzalez, 2011c3).

Illustration 1 collates relevant statistical information about a claim commonly appearing on yogurts: heart health4. The results seem to support several inferences. Firstly, that yogurts with 'heart health' claims have an average BNI lower (median = 89.62) than other yogurts (median = 93.59). Secondly, that such difference is also found between groups (U = 9374, p < 0.01). And thirdly, that there is a correlation supporting a trend between sporting a heart health claim and the yogurt having lower nutritional unbalance (rho = -0.211, p < 0.01). In any case, even when statistically significant, both the difference in medians and the correlation are rather small, and they may not be that important in practical terms.
