It's worth noting that the zapper does not reach the center of the intestine, so any bugs hiding there still need to be flushed out to prevent reinfection. This limitation is actually a very good thing in the long run, because if it killed all intestinal bacteria (as Antibiotics unfortunately do) we would lose the healthy, beneficial culture that is in there naturally breaking down the food and preventing invasion.
One cautionary note is that dead parasites left over from zapping can trigger the runs, which in some cases deplete the beneficial bacteria and leaves you open to candida and other infections. Taking a probiotic suppliment, or yogurt with acidophillus bacteria can help overcome this. Fortunately the large numbers of dead parasites are a temporary condition.
Fruits and vegetables not only help flush out toxins, they replace them with valuable nutrients with which to rebuild the body. With the parasites out of the way, the body can now make vital repairs. Beneficial organisms also seem to prefer a diet that includes adequate fiber and nutrients, whereas disease organisms prefer white flour and sugar.
Encourager, glad to see you were eating healthy anyway :) According to Hulda Clark you are not supposed to eat between zaps due to chance of reinfection. Fasting from heavy foods, taking probiotics and healthy foods, and zapping all at the same time for a certain period is probably a really great idea if you have a really bad infestation or cancer. But the zapper can do quite a lot for most normally healthy/sick people even without major dietary restrictions.
