It could very well be that the associations we see between people who eat more mushrooms and better health are just that—associations. Much like those who eat plenty of leafy greens or folks who consume nuts on a daily basis, they may just live healthier lives in general. Or maybe mushrooms really are helping! Maybe they do have chemicals that help stave off cancer or Alzheimer’s. Or maybe they’re nutritious and full of fiber, and that’s all part of the type of healthy diet we already know reduces your risk for a wide variety of disease.
