Sammanfattning: AbstractTitle: “Does beverages sweetened with stevia have benefits compared to sacarose sweetened beverages in terms of reducing short-term energy intake and appetite ratings in normal weight adults?”Author: Linda Jakobsson and Lovisa LarssonSupervisor: Jenny Van Odijk Examiner: Klara sjögren Programme: Programme in dietetics, 180/240 ECTSType of paper: Bachelor’s thesis in clinical nutrition, 15 higher education creditsDate: 31st of May 2021BackgroundObesity is a societal issue on the rise. The development of obesity is partly due to lifestyle factors and maintaining an energy intake that is too high. Diet hosts an important role in maintaining a healthy weight. According to Livsmedelsverkets Dietary guidelines from 2012 added sugars should be limited to make up a maximum 10 % of the total daily energy intake. Stevia may therefore be used in the place of sugar to provide a sweet taste without added calories.ObjectiveThe aim of this review is to examine if the plant- derived, non-nutritive sweetener stevia added to beverages has the potential to reduce short-term energy intake and appetite in normal weight adults during an ad libitum lunch compared with sugar sweetened beverages. Search strategyThe databases Pubmed and Scopus were used when conducting the literature search. The key terms that were used were divided into three search blocks containing a combination of MeSH- terms and free-search terms. The terms used in each search block were such as artificial sweetener, artificial sweetened beverage respectively appetite regulation. Selection criteriaThe inclusion criteria were studies that were conducted on human subjects and RCT-studies written in English. The studies had to examine energy intake and appetite ratings at a specific meal The exclusion criteria reads as follows: participants younger than 18 years of age and animal studies Data collection and analysisThe literature search in Scopus and Pubmed gave a total of 269 hits, three articles were eventually chosen to be reviewed further and went through a “risk for bias” evaluation usingSBU’s template “Bedömning av randomiserade studier”. One of the studies was excluded due to not being comparable with the other two. The two remaining articles were examined using SBU’s template and GRADE.Main results No reduction in the energy intake was noted during the consumption of the ad libitum lunch after the intake of a stevia sweetened beverage. One of the studies found a significant increase 5in appetite prior to the intake of the lunch amongst the participants who were given the stevia intervention. In both studies no significant differences were identified in appetite between the sucrose and stevia group after lunch.ConclusionsA low grade of evidence (++) was found supporting that the consumption of stevia sweetened beverages may reduce short term energy intake and appetite.
