Again trouble with sugar

Unclear causal relations between sugar, obesity, and dental decay
Unclear causal relations between sugar, obesity, and dental decay…

In short.

A recent article published in PLoS One (a fairly good open access journal) has a closer look at the potential relation between “Obesity and Dental Decay” with a focus on the role of common sugar. Looking at more than 8000 around 11 year old kids, the authors surprisingly found that higher obesity correlates with better dental conditions. Based on their results the authors question that high sugar consumption is the main cause for obesity (see 1s figure). The study seems to suggest that other factors might be essential to cause obesity (see 2nd figure).
