One lady was overweight with various problems, was helped by a raw foods diet. Then she started feeling weak, but the raw foods practitioner pushed her to stay on. Now she is in a state of malnutrition, her digestive system is ruined, and she has osteoporosis and a lot of other problems.
I find it very interesting that Dr Thiel says that an in vitro study found that food vitamin c has negative oxidative reductive potential (ORP), yet the Merck Index reveals that ascorbic acid has positive redox potential. This means that no quantity of USP ascorbic acid can ever match the ability of food vitamin c to clean up damage caused by free radicals. Negative ORPs indicate active reducing power, which is immediately capable of antioxidant activity where as items with positive ORPs are not.
Although measurement of the reduction potential in aqueous solutions is relatively straightforward, many factors limit its interpretation, such as effects of solution temperature and pH, irreversible reactions, slow electrode kinetics, non-equilibrium, presence of multiple redox couples, electrode poisoning, small exchange currents and inert redox couples. Consequently, practical measurements seldom correlate with calculated values. Nevertheless, reduction potential measurement has proven useful as an analytical tool in monitoring changes in a system rather than determining their absolute value (e.g. process control and titrations).
1. In a perfect world, we should all get our vitamin C from food!
2. Raw milk direct from the cow is known to have more vitamin C than oranges.
