Ginger has been demonstrated to lower triglycerides or fats but its mechanisms remain unclear. Recent evidence has suggested that Fructose overconsumption is associated with increase in fat deposit. In this study by Gao et al found that extracts of ginger (in an animal study) over 5 weeks reversed liquid fructose-induced increase in plasma triglyceride and glucose concentrations and hepatic triglyceride content.
Hypertriglyceridemia (hTG), a condition in which triglyceride levels are elevated, is a common disorder in the United States. It is often caused or exacerbated by uncontrolled diabetes mellitus, obesity, and sedentary habits, all of which are more prevalent in industrialized societies than in developing nations. In epidemiologic and interventional studies, hypertriglyceridemia is a risk factor for coronary artery disease (CAD). Medscape
The study suggests that Ginger can ameliorate of fructose-induced fatty liver and hypertriglyceridemia. They suggest that this modulation occurs due to the hepatic ChREBP-mediated pathway.
