I haven’t ever had problems in the past with wheatgrass in drinks (like Odwalla, etc), but I haven’t had any since I started the diet. I just started getting sprouts though, from the farmer’s market, which have been awesome! I got sunflowers and pea shoots, and have had no problems from them. I just eat the stalks, not the seeds, and those ones don’t get the mold on them like radish, clover, etc. do.
