When the beverage is sweet, how does the liver feel?

Area of Science:

• Pediatric Gastroenterology
• Hepatology
• Nutrition Science

Background:

• Non-alcoholic fatty liver disease (NAFLD) and its progressive form, NASH, are rising health concerns in children.
• Dietary patterns, including high intake of caloric sweeteners (CS) like fructose, are implicated in NAFLD pathogenesis.
• The increasing consumption of non-caloric sweeteners (NCS) necessitates an understanding of their impact on pediatric liver health.

Purpose of the Study:

• To review existing data on the association between pediatric NASH and sweetener consumption (CS and NCS).
• To identify knowledge gaps concerning the role of various sweeteners in pediatric NASH.
• To evaluate the potential hepatoprotective or detrimental effects of NCS.

Main Methods:

• Literature review of studies investigating sweetener intake and pediatric NASH.
• Analysis of mechanistic pathways linking dietary fructose to liver injury.
• Examination of reported effects of NCS, such as rebaudioside, on metabolic and inflammatory processes.

Main Results:

• High-fructose diets are associated with unhealthy dietary patterns in NASH patients, leading to reduced hepatic lipid oxidation and increased inflammation.
• NCS consumption is rising, with many considered safe due to lack of metabolism.
• Rebaudioside, an NCS, shows potential hepatoprotective properties via anti-inflammatory and antifibrotic mechanisms, influencing insulin secretion and microbiome diversity.

Conclusions:

• Dietary factors are crucial in NAFLD development, with a trend towards replacing natural sweeteners with NCS.
• Pediatricians should screen for NAFLD and advise against sugar-sweetened beverages.
• Further research is essential to understand the long-term hepatic effects of various NCS.
