I'm not recommending these snacks, but you can, not should, eat anything you want as long as you don't have a sensitivity to any of the ingredients. To find out if you have sensitivities keep a good food journal. There are many posts on that - see the search box at the top of the page.
Dried fruits are usually treated with sulfites to preserve color and freshness. The exceptions are cranberries and plums (prunes). Bottled juices, but not frozen, are also treated with preservatives. Many people with reflux find they get episodes triggered by additives like sulfites and other preservatives. I get tachycardia on top of esophagus and stomach spasms from sulfites.
I have tried Terra Chips and had no problem, but snacks are not food. We need to get off snacks and junk food and just eat regular, healthy meals to help ease reflux. You can't tell what other additives are in a product because the company only has to list what THEY put in, not what their suppliers add.
