So you started adding flaxseed meal to your morning smoothies and a few months later find an opened bag in the back of your pantry. Can flaxseeds or ground flaxseed (aka flaxseed meal) go bad? Yes, just like any seed, they will eventually turn. But before you toss that package, use our pointers to find out if it's still OK to use. After we cover some flaxseed basics, we'll go over how long you can store flaxseed and how to tell if it's still safe to eat. You'll also learn how to store flaxseeds so they last as long as possible to add to that bread recipe or when you need a vegan egg substitute.
