The Claim

The total dietary intake of saturated fatty acids, monounsaturated fatty acids, and polyunsaturated fatty acids is not associated with the incidence of coronary heart disease, regardless of whether these fats are substituted with carbohydrates or other fats, suggesting that the total intake of fat classes may be less important than the food source from which they are derived.

In plain English

Eating more or less of different kinds of fats—like butter, olive oil, or vegetable oil—doesn’t seem to change your risk of heart disease, no matter what you eat instead of them. What matters more might be where the fat comes from, like whether it’s in cheese, nuts, or fried food.

1 study
  1. Study: Dietary Fatty Acids, Macronutrient Substitutions, Food Sources and Incidence of Coronary Heart Disease: Findings From the EPIC‐CVD Case‐Cohort Study Across Nine European Countries

    The study found that eating lots of fats like butter or meat doesn’t necessarily cause heart disease — what matters more is what food the fat comes from. For example, cheese and yogurt fats might be fine, but red meat fats might be riskier.
