Glede na nedavno študijo o dietah, bogatimi z omega 3 maščobnimi kislinami nam te ščitijo jetra pred poškodbami, ki jih povzroča debelost in odpornost na inzulin. Zaradi teh raziskav naj bi zdravniki in strokovnjaki za prehrano priporočali jemanje omega 3 maščobne kisline pri hujšanju. Omega 3 maščobne kisline je mogoče najti v oljih in ribah
"Our study shows for the first time that lipids called protectins and resolvins derived from omega-3 fatty acids can actually reduce the instance of liver complications, such as hepatic steatosis and insulin resistance, in obese people," stated Joan Claria, a professor from the University of Barcelona and one of the researchers involved in the work.
The scientists found that two types of lipids in omega-3 fatty acids—protectins and resolvins—were the cause of the protective effect. To reach this conclusion, they studied four groups of mice with an altered gene making them obese and diabetic. One group was given an omega-3-enriched diet and the second group was given a control diet. The third group was given docosahexaenoic acid, and the fourth received only the lipid resolvin. After five weeks, blood serum and liver samples from the test mice were examined. The mice given the omega-3-rich diet exhibited less hepatic inflammation and improved insulin tolerance. This was due to the formation of protectins and resolvins from omega-3 fatty acids.
"Doctors are always looking for simple and easy ways to counter the harmful effects of obesity, and the great thing about this study is that the information can be used at dinner tonight," said Gerald Weissmann, M.D., Editor-in-Chief of The FASEB Journal. "It's not unlikely that eating lots more fish or a simple switch to canola oil will make a difference."
