The Claim
In calorie-restricted C57BL/6J mice, dietary lipid composition influences lifespan, with diets lower in polyunsaturated fatty acids and higher in saturated and monounsaturated fats potentially associated with increased longevity.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In mice on a low-calorie diet, the type of fat they eat might affect how long they live — less polyunsaturated fat and more saturated or monounsaturated fat could help them live longer.

Dietary lipid composition may influence lifespan in calorie-restricted C57BL/6J mice, with lower proportions of polyunsaturated fatty acids and higher proportions of saturated and monounsaturated fats potentially supporting greater longevity.
What the research says
1 studyStudy: The Influence of Dietary Fat Source on Life Span in Calorie Restricted Mice.
The study found that mice on a low-calorie diet lived longer, especially when their fat came from lard instead of oils high in polyunsaturated fats. This supports the idea that the type of fat matters for living longer when eating less.
