If you read you noticed the 1 month of meals came from the clinic to give people to go home with. Dr. Hay did not use these foods in the clinic, these foods are compatable foods, not all human foods, this is why you would need to repeat the fasting once per year. In future schooling books I use a MD that only did the fasting one time and ate human foods and became one of the strongest men I have ever seen at age 76 when he wrote his first book.
I thought about taking the 30 day food guide out of the book because people don't seem to understand it. Many are looking for any excuse to not try the oranges and I hear allot about this 30 days of food as the reason.
Dr. Hay more than explains food long before this part of the book and this was given because the clinic new people are hard headed and will not change, so they were trying to make it easier. Also, milk is considered the perfect food, the problem is, today you can not get good milk and humans refuse to consume it properly.
