Special Issue Information

Dear Colleagues,

The global prevalence of overweight and obesity has steadily increased in recent decades and the role of dietary sugars in body weight regulation is still a topic of controversy. Different research topics are of great interest to further elucidate the role of dietary sugars in the development of overweight and obesity:

  • Effects of dietary sugars on body weight, including added, free and total sugars as well as certain monosaccharides such as fructose and others.
  • Neuronal and molecular mechanism of dietary sugars in brain areas as well as peripheral organs, which might contribute to body weight gain. For example, this includes central areas in the regulation of hunger and satiety as well as peripheral areas which are involved in glycemic control.
  • The role of sweet taste and sweet preference on overweight and obesity.

All types of human and animal studies are welcome for this issue, including intervention studies, observational studies, systematic reviews and meta-analyses or modeling studies. Narrative reviews are also welcome.

Guest Editor

Intake of Free Sugars and Main Food Category Contributors among French Children, Adolescents and Adults
by Chloé Deshayes, Louise Seconda, Philippe Reiser, Philip Prinz and Pascale Hebel

A high intake of free sugars (FS) is assumed to be associated with overweight and obesity as well as type 2 diabetes mellitus and cardiovascular diseases. Therefore, the World Health Organization (WHO) recommends an intake of FS of less than 10% of daily total energy intake (TEI). The purpose of this study was to update the FS intake data for the French population, including children and adolescents as well as adults, based on the 2019 French Food Behavior and Consumption survey (CCAF). FS intakes were assessed at 67 g/day (15.3% of TEI) in children and adolescents as well as 57 g/day (10.5% of TEI) in adults. The main FS contributors were cakes/pastries, sugary drinks and fruit juices in children as well as sugary products, cakes/pastries and fruit juices in adults. The contribution of FS intakes to TEI fell with age, from 15.6% of TEI in 3–6 years children to around 8–9% for adults older than 50 years. On average, children were above the WHO recommendation of FS intake, but adults were close to or even below the threshold of 10% TEI. These observations are of great importance to prospective public health activities focusing on changes in FS intakes. Full article

Non-Centrifugal Sugar (NCS) and Health: A Review on Functional Components and Health Benefits

Non-centrifugal sugar (NCS) is the scientific term the Food and Agriculture Organization (FAO) uses to define a solid product, produced by sugarcane juice evaporation, which is unrefined or minimally refined. NCS is referred to in various names globally, the most significant ones are whole cane sugar, panela (Latin America), jaggery (India) and kokuto (Japan). NCS contains minerals, bioactive compounds, flavonoids and phenolic acids, which have therapeutic potentials from time immemorial. Even though the bioactive property is dependent on the composition, which relies mainly on the agronomic conditions and production process, NCS possesses antioxidant and anti-inflammatory properties. Hence, substituting the consumption of refined sugar with NCS might be helpful in the control of chronic diseases generally connected to oxidative stress and inflammation. Experimental facts from in vitro and in vivo models have proven that NCS plays an essential role in weight management, maintaining insulin sensitivity and preventing neurodegenerative diseases. NCS has also shown hypoglycemic and hypolipidemic effects. This review aims to synopsize the recent literature pertaining to the benefits of NCS in human health. The NCS can be considered a nutraceutical and functional food. However, detailed and regulated studies are important to enhance the beneficial effects in human and animal interventions. Full article

Assessment and Evaluation of the Intake of Sugars in European Countries

The intake of sugars is a trending topic in nutrition and health. For an evaluation of the sugar intake (comparison with existing guidelines), up-to-date information on the guidelines, dietary intake and trends in the intake is needed. The available information for European countries is presented in this review. The existing guidelines on the intake show that there is currently no consensus among the experts from different organizations. The differences are mainly due to the selection of the adverse health outcomes for which there is sufficient evidence. Data from national European surveys show that the mean proportion of energy coming from added sugars for most European population groups is below 10%, and that the trend in the intake seems to be downwards. There are, however, many serious uncertainties and assumptions needed for the assessment of the intake of sugars. For instance, the assessment reflects a short period of the lives of the respondents, the data collection in several surveys was conducted more than 10 years ago, and recent reformulations of the industry are not considered in the food composition tables. Due to the uncertainties regarding the assessment of the sugar intake in Europe, the information should be used prudently and with care. Full article

This review summarizes current studies on the psychological effects of sweet taste and its role in overweight and obesity. Recent psychological studies demonstrate intriguing relationships between the experience of sweet taste and social perceptions and behavior. For example, studies show that experiencing sweet taste affects “helping behavior” or interest in initiating a romantic relationship. Furthermore, given that the role of sweet taste in obesity has been suggested, we reviewed studies on the relationship between sweet taste preference and eating behavior, thereby examining the role of sweet taste (and the preference for it) in the global rise of overweight and obesity in adults and children. Finally, we provide an outlook on future research perspectives on the psychological effects of sweet taste, and suggest some fundamental issues that future research should address to help provide a comprehensive understanding of how sweet taste and sweet taste preference affect our thinking and eating behaviors.
