Abstract
Overconsumption of sucrose or fat is widely acknowledged as a prominent feature of unhealthy dietary patterns. Both factors commonly co-occur and are recognized as hallmarks of the Western diet, which is an important contributor to non-communicative diseases. In this study, we investigated the hazards of high sucrose or fat intake, either alone or in combination. Wistar rats were divided into four groups and fed a control starch diet, high-sucrose diet, high-fat diet, or high-sucrose/fat diet for 30 days. High fat intake increased body weight and visceral and subcutaneous adipose tissue weights. Both high-sucrose and -fat diets were associated with increased plasma triglyceride and glucose levels, and high sucrose also elevated plasma cholesterol levels. The combination of high sucrose and fat synergistically elevated plasma triglyceride levels. The high-sucrose diet increased liver weight and hepatic total lipid and triglyceride levels, whereas this increase was suppressed by the high-fat diet. The high sucrose increased the mRNA levels of hepatic genes involved in fatty acid synthesis and transport (ACLY, ACACA, FAS, ELOVL6, SCD1, SREBP1, and CD36), whereas the high fat suppressed the high sucrose-induced expression of these genes. We observed that high sucrose and fat contents differently exerted their effects on hyperlipidemia and fatty liver. Furthermore, high fat aggravated hyperlipidemia and suppressed fatty liver induced by high sucrose.
