Growing up in a small town in Iowa, I was surrounded by a LOT of farming. My wife describes the two hour drive from the airport to the my home town as nothing but cornfields, which is pretty accurate. So when I first read about the seed and soil theory of cancer, it made a lot of sense to someone with very limited medical knowledge.
The theory dates back over 100 years, and in a nutshell it says that tumor cells (seeds) can only colonize particular distant tissues (soil) that have a suitable growth environment. In a garden weeds can only flourish if the soil conditions are right and by controlling the soil, you can have some impact how the weeds spread.
How do you change the soil? One of the big ways seems to be diet, I will go into what I am doing on that front later. I’ll be the first to admit that I used to believe what you put into your body has very little impact on diseases such as cancer, but I’m beginning to rethink that. Here are some TED videos I found interesting that talk about research being done on what role the microenvironment (soil) plays in cancer and how diet can help cut off cancer’s food supply.
