"My constipation+foul odor occured when I was healthy and had no candida issues."
In my opinion constipation and foul odor from eating green vegetables is not an indicator of being healthy. Most likely you already had candida issues from a long time ago...perhaps there is something you did or some life change that happened to you that allowed it to run rampant. In my case I did Antibiotics and stopped eating raw garlic. Within a period of 2 years it became a total monster.
Greens are so effective against candida and other fungus's precisely because of their alkalinizing effect on the body. The effect of diet upon the body's pH is certainly not a myth. I know of several people who have eliminated skin fungus simply by eating loads and loads of greens. I know of people who have killed parasites simply by eating loads and loads of greens thereby raising their pH. What is so difficult to understand?
