According to a recent study, diets rich in omega-3 fats can protect the liver from damage caused by obesity. This could help explain why some obese patients are more likely to suffer complications associated with obesity.
Lipids called protectins and resolvins, which are derived from omega-3 fats, can actually reduce the incidence of complications such as hepatic steatosis and insulin resistance.
Researchers studied several groups of mice with an altered gene which made them obese and diabetic. Mice given a diet rich in omega-3’s exhibited less hepatic inflammation and improved insulin tolerance.
