A diet high in α-linolenic acid and monounsaturated fatty acids attenuates hepatic steatosis and alters hepatic phospholipid fatty acid profile in diet-induced obese rats
A diet rich in certain healthy fats reduces liver fat buildup and changes liver fat composition in obese rats

Abstract
Rats on a canola/flax oil blend diet showed 20% less liver lipid after 12 weeks compared to weight-matched groups.
- The canola/flax oil blend diet is associated with significant reductions in liver lipid levels.
- Body mass, liver weight, glucose and lipid metabolism, inflammation, and fatty acid processing markers did not explain the observed reduction in liver lipids.
- Hepatic phospholipids from the canola/flax oil blend group contained the highest levels of total n-3 fatty acids and eicosapentaenoic acid (EPA).
- This group also exhibited one of the highest concentrations of docosahexaenoic acid (DHA) and the lowest levels of arachidonic acid (n-6).
- The findings indicate that a diet rich in plant-based n-3 fatty acids may alter the fatty acid profile in the liver.
