Presence and consumption of sugars and low and no-calorie sweeteners in the Spanish diet: an updated overview.

Abstract

Introduction: the term "sugars" describes a specific group of carbohydrates and one of the most controversial components of our diet, as public health authorities worldwide acknowledge that there is an excessive intake. Reformulation practices with low and no-calorie sweeteners (LNCS) are being carried out worldwide. However, a lack of information about the present market status and evolution is highly recognized. Materials and methods: review of the most recent studies. Results: there is a lack of comprehensive Food Composition Tables (FCT) and Databases (DB) including sugar contents and many countries have developed their own for the estimation of sugar intakes or with the aim of monitoring changes in processed food composition. Moreover, surveys assessing carbohydrate and sugar consumption and their dietary sources are scarce and sometimes not comparable due to the different methodologies, FCT and DB used, and non-harmonised use of terms and nomenclature, especially for the estimation of added sugars. Results from studies show that total and added sugar intakes around the world are quite comparable in terms of percentage of total energy from diet and major dietary sources. WHO's recommendations are being exceeded, especially amongst the younger population groups. Conclusions: future research on sweeteners, both caloric and low or non-caloric, should comprise the development of comprehensible, harmonized and updated databases of added sugar and LNCS, the evaluation of the frequent consumption of LNCS from foods and beverages and its potential association with an improved food model/pattern and lifestyles. Finally, intervention studies with LNCS are urgently needed.
