Does a diet consisting of raw food or juicing guarantee enough enzymes to meet our needs?

Raw food provides only enough enzymes to digest that particular food. There are no extra enzymes in raw food to digest the other cooked or processed food we eat. Although a totally raw diet may appear to be the best solution, it is generally not practical, and in most cases, not medically advisable. Due to the risk of bacterial contamination, many foods should not be eaten raw, including meats, poultry, eggs and beans. Many people also find the fiber content in large quantities of raw food difficult to digest.
