As a low carber I'm not certain so much fruit is allowed.. unless you are doing susanne somers, fat flush or paleothin which are not actually considered low carb diets.. but if you are doing Atkins, Kim-Kins or something similar, and have been on the first phase of the diet for more than two weeks.. nuts are allowed *except peanuts and cashews which are considered beans and extremely high in carbs*.. you can take nuts *raw is better than salted* or make your own nut butters and dip celery sticks.. take beef or turkey jerkey *double check to buy it without added corn syrup or sugars*, soy chips and low carb snack bars available at your local grocery or health food stores. You may even want to check for recipes online for low carb granola which is usually made of flax seeds, nuts and so on... I would reccommend the cookbook "Extreme Lo-Carb Meals on the Go" which has a wonderful pumpkin granola *recipe made from pumpkin seeds*, as well as recipes for low carb muffins, fake fudge, cheese sticks, jerky & zucchini nut bread... oh, and you can also toast pepperoni slices in the oven.. they get very crunchy and they last well in a sandwich bag... bags of flavored or plain pork rinds, and low carb meal replacement drinks in a can are great in a crunch too... just be sure to read, read, read the ingredients..
All the best and a safe trip to you...
