I eat lots of nuts and seeds. I have a salad every day for lunch and put raw pumpkin seeds in it. I also eat pistachios, cashews and sunflower seeds. No issues eating them but I do chew them well. Chewing all foods well is crucial with a Pouch otherwise it comes out undigested.
I also drink cashew, almond and coconut milks. I get the unsweetened varieties. They are really good. Califia Farms make the best nut milks, although if you can't find it Silk is pretty solid.
