I been eating nuts since 2 months post op and I chew them well,so far is the only thing that has been working for my constipation YES I make my own trail mix with almonds and organic raisins and I eat 1/4 cup a day and it gives the energy I need to go for runs,walks or the gym =) Not everybody tolerates them well after surgery. Almonds are my favorites. I do a little peanut butter as well here and there but I limited myself to the serving size 2 tsp. They are a great source of protein and healthy fats as well as fiber but is small quantities ,for what I read,is also good to gain a couple pounds if you eat a lot. I love me some nuts lol
