Re: ginger and wasabi

I've been reading on other sites about sushi, and parasites, and wasabi and ginger and so many other interesting things! Some sites say wasabi is helpful for killing bacteria. I wouldn't be surprised, that stuff is POTENT! Some sites say it is just for good digestion (enzymes).
I am on my second week of cleansing, third day of Paragone parasite cleanse. I know this stuff is working. I won't get into details. :)
I sometimes argue with myself about things like this. Is it inevitible that we will end up with parasites again unless we live a pristine life? I have pets and plan to open a dog kennel. Is doing a yearly parasite cleanse sufficient to keep them at bay along with being overall more healthy to help my body fight everything off?
I mean, can I keep doing the things I am doing, knowing that I'm going to get more parasites later, and just cleans to keep them from taking over?
So many thoughts...
