1. There are no USDA regulations on honey. So what you get in the supermarkets may not be a 100% honey, or may be mixed with low grade honeys so you will not get 100% honey.
2. Large scale commercial processing of honey includes a multi-filtration process that filters out most if not all of the "good" honey properties like; pollen.
3. Honey is the only food substance that contains all the necessary substances to sustain life including enzymes.
