The Claim
In calorie-restricted C57BL/6J mice, a diet high in monounsaturated and saturated fats derived from lard is associated with a longer lifespan compared to diets rich in n-3 or n-6 polyunsaturated fatty acids from fish oil or soybean oil, indicating that lower dietary intake of polyunsaturated fats may promote maximal longevity under conditions of calorie restriction in this mouse model.
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, eating more fat from lard seems to help them live longer than eating fats from fish or soybean oil.
See the scientific wording
In calorie-restricted C57BL/6J mice, a diet high in monounsaturated and saturated fats from lard is associated with longer lifespan compared to diets high in n-3 or n-6 polyunsaturated fatty acids from fish or soybean oil, suggesting that lower dietary polyunsaturated fat intake may support maximal longevity under calorie restriction in this animal model.
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 when their fat came from lard instead of fish or soybean oil, which matches the claim.
