Organic acids from ice wine ameliorate fructose-induced disorders of glycolipid metabolism in C57BL/6J mice†

Excessive intake of fructose has been widely reported to cause glycolipid metabolism disorders, and it is unclear whether long-term consumption of ice wine, a sweet wine with high sugar content, is beneficial for health. In this study, 6-week-old male C57BL/6J mice were divided into pure water, ice wine, fructose, fructose + succinic acid, fructose + malic acid and fructose + alcohol groups to study the effects and mechanisms of organic acids on glycolipid metabolism. The results indicated that long-term consumption of ice wine did not lead to disorders of glycolipid metabolism, and organic acids inhibited the negative effects of fructose and reduced hepatic fat synthesis by decreasing the mRNA expression of hepatic ACC1, SREBP-1c, and ChREBP-β, as well as controlling the protein expression of KHK-C. These findings provide a theoretical basis for the healthy consumption of ice wine, helping consumers enjoy wine more scientifically and promoting the high-quality development of the industry.
