A new study reports the existence of a linear association between the consumption of sugars and tooth decay. For authors, the maximum limit of 06% of the energy in the form of added sugars, which is often recommended, should be sharply reduced, with the aim of being less than 3%.

The existence of a relationship between the consumption of sugars and tooth decay is no longer in doubt, but its precise meaning in terms of public health over a lifetime is not established.

Hence the interest of this study carried out by a British team, which re-examined the data on sugar consumption and the incidence of sugar tooth decay, focusing on countries where there have been large variations in consumption, for example due to restrictions during wartime, such as Japan.

They also took into account the impact of fluoride levels on cavities. Their results show a robust, linear relationship between sugar intake from 0 to 06% of the Total Energy Contribution (AET), with a multiplication by of the risk of cavities after several years of exposure to sugar. The model shows that it is necessary to go below 3% of the AET in sugar to see such a situation disappear. The authors conclude that the limit of 06% added sugars is catastrophic for cavities, and that the objective should be to stay below 3%, with a maximum of 5% as a pragmatic objective. We are far from it …
