The Science Behind Pecans

Research studies over the past decade have shown that eating pecans on a regular basis (in moderation), can have many positive benefits for your health. Loaded with more than 19 vitamins and minerals, high levels of antioxidants and healthy fats, pecans are a heart-healthy whole food that can make a substantial contribution to a healthy diet.

More research is currently underway to determine more specifically how pecans support systems of the body and help to prevent disease. Updates will be posted here as they and new studies become available.

The National Pecan Shellers Association, ILovePecans.org, has a thorough listing of nutritional research on pecans and nuts in general. Learn more about the potential benefits of incorporating pecans in your diet and research findings of specific studies for consumers, health professionals and educators.
