Natvia (and Truvia in the US) is a sugar free blend of stevia and erythritol and you may have noticed that they are starting to become very popular in the supermarket as a sugar replacement and also as an ingredient in many processed food items such as muesli bars, jams and chocolate. Personally, I don’t have anything against Natvia, I think it is a great sugar alternative for the general public. However for those of us who suffer from IBS it MUST BE AVOIDED! And this is why…
Erythritol, one of the two key ingredients in Nativa, is advocated by many as a safe and easily digestible sugar alcohol, which you can read about on wikipedia. As it is a sugar alcohol it contains polyols which needs to be avoided if you are following the low fodmap diet to manage symptoms of IBS. I am incredibly sensitive to sugar alcohols and erythritol is no exception. Please be extremely cautious if you consume a product containing Natvia and monitor your symptoms closely for three days (you never know, you might be able to tolerate small amounts!). For me, on day 2 and day 3 I experience pain and constipation that is difficult to manage. I don’t go near the stuff.
Instead of using Natvia to replace sugar, I use rice malt syrup (read about that here) and pure stevia. See the photo for the exact stevia product that I use: I bought it on-line and I have been using the same tub for 2 years as you only need to use the tiniest amount!
All the best,
