Well, it was required for them to grow. So it ‘helped’ on that count.
I had several jars at varying stages of growth. As for being ‘the most dangerous food to eat’, nope. Come to Japan, catch your a puffer and prepare it yourself. THERE is danger for you. So ‘one doctor’ said this? Not 3xactly volumes of research, huh?
Wearing rubber gloves, respirators for anything that has an odor, etc, etc. 8’m still here. I handled mercury as a kid, worked on cars and painted everything that could be painted without gloves, worked construction with no safety glasses. When I was in the 9th grade I even used a hacksaw to cut off a small piece of the chunk of uranium for my science teacher. IN THE CLASSROOM. My dad had it from when he worked at Los Alamos during the war. THAT was dangerous. Or potentially so. When I was in college I took that piece of uranium to the physics department. I let them have it for a day. When I came back to pick it up they had it wrapped in several pieces of land. They said it was hotter than anything they ever had in that lab. That was dangerous. Not growing sprouts in a jar. Take a deep breat, and relax. You WILL die, but chances are it won’t be from not wearing gloves/safety glasses or eating homemade sprouts.
