Psyllium husk
Psyllium husk is a baking ingredient derived from the husks of Plantago ovata seeds. It may help decrease blood sugar since it behaves similarly to xanthan gum in your intestines, making it an excellent replacement. While high dosages of xanthan gum have been associated with digestive and respiratory difficulties, many small studies suggest that high doses may help decrease blood sugar.
Although additional study is needed, this impact might be because xanthan gum and psyllium husk are soluble fibers that your digestive tract cannot break down. Instead, they produce a gel-like material that aids in the slowing of absorption. When baking, replace 1 part xanthan gum with 2 parts psyllium husk.
