The older I've gotten, the more I've realized that health (and other life conditions) are more nuanced than they are black and white. And that sometimes bodily conditions aren't solved by any physical actions (like medicines, exercises etc.) because their source has more to do with the inner side of life than the physical.
I recommend checking out a book (or video interviews on youtube) by a cancer survivor named Anita Moorjani, who tried everything under the sun to fix her health problems, to no avail. She eventually had a crazy experience and realized that the cause of her problems was much different than what she thought.
There's also a spiritual teacher named Abraham Hicks, with thousands of audios on youtube, who I've found to be brilliant. They have helped me a ton in understanding why my life is the way it is, how it can be improved, and provide tremendous insight into diet, and understanding health cause and effect.
