Public interest in weight loss and diet-related topics in Europe: an infodemiology study of Google trends data from 2004-2022.

Obesity is one of the largest health issues in Europe, and media can significantly impact obesity-related habits. This study aimed to determine the trends of public interest in weight loss, physical activity, diet, nutrition, healthy diet, healthy nutrition, optimum nutrition, healthy food, and a combination of weight loss + diet-related topics in Europe, using Google Trends data from 2004 to 2022. Denmark was the most interested in weight loss topics, whereas Ukraine was the least interested. The mean relative search volume (RSV) of "Weight loss + Optimum nutrition" was the most frequent (80.65%), followed by "Weight loss + Physical activity" (78.66%). Searches for "Weight loss" + diet-related topics increased in most European countries according to Jonckheere-Terpstra trend analysis from 2004 to 2022, with searches generally declining in December but increasing in January. Our findings could help scientists and practitioners develop and select strategies, particularly during times of high public interest.

Added sugars and non-nutritive sweeteners in the food supply: Are they a threat for consumers?

BACKGROUND & AIMS: Excess sugar intake can cause chronic diseases such as obesity, diabetes, and cardiovascular disease. Thus, limiting the intake of sugar in the diet is an important preventive measure. Food manufacturers have considered non-nutritive sweeteners (NNS) as an alternative to sugars. To date, there has been no systematic monitoring of the types of added sugars and NNS in Turkey's food supply. The aim of this study identified the added sugars and NNS in packaged foods and beverages that were available in supermarkets across Turkey. METHODS: A cross-sectional study was conducted from April to December 2020. Three supermarkets in Turkey were chosen for this study. RESULTS: Of the 2514 packaged foods and beverages analyzed, 1647 (65.5%) contained added sugars or NNS. Out of 1647 products, 9.7% contained both added sugars and NNS; 86.5% only added sugars whereas 3.8% had only NNS. The most used added sugar was white sugar in all food groups (50.6%-100%) while the most used NNS was sorbitol (28.4%). CONCLUSION: The use of added sugars and NNS in Turkey's food supply was found to be high, and white sugar being the most used sweetener in products available in the food supply. Therefore, it may be important to start monitoring the prevalence of products containing added sugars and NNS due to their negative health effects.

Polyphenols in the prevention and treatment of non-alcoholic fatty liver disease: An update of preclinical and clinical studies.

BACKGROUND & AIMS: The prevention and treatment of non-alcoholic fatty liver disease (NAFLD) has become one of the most urgent problems to be solved. To date, only a lifestyle modification related to diet and physical activity is considered for these patients. Polyphenols are a group of plant natural products that when regularly consumed has been related to a reduction in the risk of several metabolic disorders associated with NAFLD. In this study, we aimed to present an overview of the relationship between polyphenols and NAFLD with current approaches. METHODS: We performed a comprehensive literature search for articles on polyphenols and NAFLD published in English between January 2018 to August 2020. Keywords included in this review: "Phenolic" OR "Polyphenol" AND "Non-Alcoholic Fatty Liver Disease". The editorials, communications and conference abstracts were excluded. RESULTS: Different polyphenols decreased the pro-inflammatory cytokines in both serum and liver that contribute to a decrease in fatty liver dysfunction. Additionally, polyphenols may improve the regulation of adipokines and prevent hepatic steatosis. According to human clinical studies, polyphenols are promising for NAFLD patients and associated diseases that lead to NAFLD. CONCLUSION: Preclinical and clinical studies suggest that various polyphenols could prevent steatosis and its progression to non-alcoholic steatohepatitis, as well as ameliorate NAFLD. However, more clinical studies are needed to confirm this hypothesis.
