In the study, the placebo group started [with A1c levels] up at around 9, and stayed up around 9. But the brewer’s yeast group dropped from 9 to 8. So, they weren’t cured, but in three months’ time, they were able to achieve significantly better diabetic control just eating half a teaspoon of brewer’s yeast a day, which would cost about 4 pennies a day—4 cents a day.

What about for just seven weeks? Again, a total of about a half-teaspoon of brewer’s yeast a day. Started out with an A1c level of 8. The placebo appeared to help a bit, but the yeast, even more. From 8 down to an almost nondiabetic 6.6. That’s amazing; how could it be? Well, the drug industry has been trying for decades to discover the so-called Glucose Tolerance Factor in yeast; after all, no shareholder is going to be happy with a therapy you can buy for only 4 cents a day.
