The Claim
In C57BL/6J mice, the composition of dietary fat modulates the levels of polyunsaturated fatty acids in membrane phospholipids, and because phospholipid PUFA levels can be altered by diet, this supports a biologically plausible mechanism through which diet may influence 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.
What mice eat affects the fats in their cell membranes, and since diet can change these fats, it might help explain how food could influence how long they live.
See the scientific wording
Dietary fat composition influences membrane phospholipid polyunsaturated fatty acid levels in C57BL/6J mice, as phospholipid PUFAs are modifiable by dietary intake, supporting the biological plausibility of diet-driven longevity effects.
What the research says
1 studyStudy: The Influence of Dietary Fat Source on Life Span in Calorie Restricted Mice.
The study shows that mice on a low-calorie diet lived longer when their fat came from lard instead of oils high in certain fats, which supports the idea that the type of fat you eat can change your cell membranes and affect how long you live.
