People healing themselves from diseases?

I saw a preview for a documentary of self-healing from diabetes. It was a raw food diet. I've heard this helps with cancers as well... at least in some cases. Some also have claimed that a diet high in fermented foods have kept HIV Aids at bay, as well.

Some psychologist believe that if you personally believe that something will heal you, it will. The mind has the ability to overcome and heal the body as a matter of positivity and willpower.

Look up a product called Diatomaceous Earth, otherwise known as Fossil Shell Flour. If you read any of the testimonials, people say it has done wonders for all sorts of ailments.
Personally, it has gotten rid of a disgusting outbreak of fleas in my house (Ew, ew, ew!), and I do admit to taking a teaspoon of it in juice each day. That aching and arthritic knee I was having problems with? Not so much anymore. Not even a twinge.
Not even a twinge.
There are people who claim it has helped lower high blood pressure, stabilize blood sugar levels, detoxed their systems, and yes, even cured cancer. Whether or not it was just a placebo effect I cannot say, but they are convinced it has done these things.

Don't put all of your trust in these books keep taking medical advice.

There are many valid alternatives to allopathic medicine which are being suppressed from public knowledge. Watch Bob Beck's protocol video on YouTube, you may find this interesting.

Anyone with cancer should ramp-down on the carbohydrates in their diet. Carbs are deleterious to health and turn to sugars in the body. Cancers feed on sugar!

They should also seriously consider removing all (where possible) polyunsaturated fats from their diet as they are potent suppressors of the immune system in addition to other adverse health features.

Taking the nutrient CO-Q10 at least 100 mgs daily (considerably more if ill) which boosts the immunity and has other health benefits. Avoid capsules that have in the mixture polyunsaturated oil.

Take either or both the amino acid l-arginine (in gram dosages) and/or ozonated water. Those increase the body's oxygen levels and oxygen kills cancers. Wheat grass juicing also has the same effect.

A return to red meats with lashings of saturated fats should prove to be of considerable benefit as this is the stomach's natural food. Avoid too where possible processed foods which are denatured with unnatural additives.
