Surprising Findings
Saturated and monounsaturated fats from lard extended lifespan more than omega-3-rich fish oil under calorie restriction
Fish oil is widely promoted for longevity and heart health, yet here it was linked to shorter lifespan compared to lard in calorie-restricted mice.
Practical Takeaways
Consider the type of fat in calorie-restricted diets, favoring lower PUFA sources like animal fats or olive oil.

If your food has bad fats, your body uses up its antioxidants fighting those instead of using them to protect your cells and help you live longer.
If you eat less food, having more saturated fats in your body might help you live longer.
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.
