The Claim
Dietary fats with higher saturation, including saturated and monounsaturated fats, exhibit greater chemical stability and reduced susceptibility to oxidation, which may contribute to increased longevity when consumed under conditions of caloric restriction.
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.
Fats that are more saturated, like those in butter or olive oil, don’t break down as easily in your body, and that might help you live longer if you're eating fewer calories.

Dietary fats with higher saturation (saturated and monounsaturated) are more chemically stable and less prone to oxidation, which may contribute to increased longevity under caloric restriction.
What the research says
1 studyStudy: The Influence of Dietary Fat Source on Life Span in Calorie Restricted Mice.
The study tested different fats in mice on a low-calorie diet and found that those eating more saturated and monounsaturated fats (like in lard) lived longer than those eating more polyunsaturated fats. This supports the idea that more stable fats may help extend life during calorie restriction.
