Now that we have presented both sides of the story, the ball is now in your court. If you can stick to a strict and controlled limit of pecan nuts then you are sure to reap all its health benefits. Just keep a check for any allergic reactions. And to lose the pounds you might need to exercise routinely.
The digestive issues that pecans bring with them can be countered by eating sprouted nuts. Sprouted nuts are easier to digest since they are already in the process of turning into plants.
Keep a check on the portions of pecans you eat and you will see only positive effects on your body. Overeating, on the other hand, is always dangerous.
