I have never found ONE turkey bacon product that did not have sugar in it. Much sausage is the same way. Out of curiosity I checked pork bacon products and all brands hand some kind of sugar in it except for one, and that one was smoked. So I would say just avoid all packaged bacon, they all have sugar, are smoked, or have nitrates.
I think the majority to all of prepackaged foods are going to have preservatives or something you need to avoid — citric acid, soy lecithin, xantham gum, tapioca starch, dextrose, lactose, or some kind of sugar…
At my local grocery, I could not find ONE soup stock base that didn’t have yeast extract or dextrose or carrots or sugar in it. There’s a vegetable broth at Trader Joe’s that is candida-safe but that’s the only one I’ve found and I didn’t find it very tasty. In the end I developed my own soup stock recipe which I need to make in bulk for the coming winter 🙂 I’ll share it on the Recipes section after I’ve made it a few times.
