Mark Twain was once quoted as saying, “Too much of anything is bad…” That holds true for seitan! While it’s a great substitute for meat and made with plant-based ingredients, a lot of seitan products come heavily seasoned to help it taste better and closer to real meat. They could be loaded with sodium, and eating too much of it can be bad for you.
If you buy seitan that’s not been pre-seasoned or made the seitan yourself, healthy servings might be alright. Put simply, don’t go overboard and eat seitan sparingly.
