Summary

Experts looked at many studies and found that swapping butter for oils like sunflower or soybean oil might help your heart, but swapping it for bread or pasta doesn't seem to help much — unless the bread is whole grain.

Surprising Findings

Replacing saturated fat with refined carbs shows no clear benefit for heart disease—even though this was the basis of decades of low-fat dietary advice.

For 40+ years, public health guidelines told people to cut fat and eat more carbs. This review says that advice may have been misguided if the carbs were refined.

Practical Takeaways

Swap one daily source of saturated fat (e.g., butter on toast) with a polyunsaturated fat source (e.g., sunflower seed butter or a handful of walnuts).
