So I know a lot of people love their ketchup (catsup) but hey, it's got a lot of sugar in it usually. Well, I went in search of a good sugar-free ketchup and I found one! I love it! I don't use a lot of it so a 13oz bottle lasts me about 2 months. What brand do you ask? Westbrae Natural Vegetarian Unsweetened Ketchup!
Ingredients: Water, tomato paste (from red ripe tomatoes), apple cider vinegar, salt, onion, maltodextrin (from corn), spice, natural flavor.
Now, some of you are going to argue that maltodextrin is NOT paleo/sugar-free but I disagree.
Yes maltodextrin has a glycemic index of over 100, however it's in such small quantities in this ketchup that it's not even worth noting, a tbsp or two with your food is going to have a negligible effect on blood sugar levels and insulin activity, if you drink a bottle or two ok yes you might be getting enough to make a worthwhile difference bbbuuuttttttt if you are drinking 26 ounces of ketchup in a meal you have other issues.
"Oh but maltodextrin from corn! Corn is a grain! Corn isn't paleo!" *facepalm* Maltodextrin can come from any number of sources, likening maltodextrin to corn is like saying "I can BBQ with diamonds instead of charcoal because they are both carbon!".
Look, if you want ketchup that's sugar-free this is the best solution I've found that doesn't involve a lot of labor (try making your own, it's a giant time-suck). This stuff tastes wonderful, 2-tbsp takes care of a pound of hamburger for me (two 1/2lb patties) and adds a whopping 10kcals and 2g of carbohydrates (from the tomato paste) to a meal. If you are concerned about the maltodextrin, and just won't listen to me, buy some of the ketchup and get a blood-glucose meter and experiment with a bottle... for the vast majority of people you'll find a negligible change.
