The study was based of a randomized controlled trial composed of 26 men and women over a four-week period. They ate either a controlled diet with no nuts, or one where pecan contributed to 15% of the total calories.
Pecans have extremely high levels of monounsaturated and polyunsaturated fats, so substituting a portion of the saturated fat in the diet with these healthier fats has been proven to benefit cardio-protective effects.
Ultimately, pecans improve insulin sensitivity as well as cardio metabolic markers.
