Can Pecans Help Improve Cholesterol?
Switching daily snack foods to pecans improved cholesterol levels and enhanced overall diet quality, according to a new study by researchers in the Penn State Department of Nutritional Sciences.
The researchers randomized adults who live with or are at risk for metabolic syndrome — a set of conditions that increase a person’s risk for several chronic diseases — to either consume pecans instead of their usual snacks or to continue eating their usual diet. Participants who ate pecans in lieu of their usual snacks demonstrated reductions across cholesterol measurements linked to poorer heart health compared to those that did not snack on pecans. Additionally, diet quality, as measured by adherence to the Dietary Guidelines for Americans, was 17% higher at the conclusion of the study for participants who consumed pecans. Results of the study were published in American Journal of Clinical Nutrition.
“Replacing typical snacks with pecans improved key risk factors for heart disease including blood cholesterol levels and diet quality,” said Kristina Petersen, associate professor of nutritional sciences at Penn State and co-author of the study. “These results add to the large evidence-base supporting the cardiovascular benefits of nuts and add additional insights into how adults can incorporate nuts into their diet to improve the overall quality of their diet.”
