Raw goat and sheep cheeses and milk products are great alternatives because their genetic code and fat content is apparently more like humans. I'd still be cautious with these, however. There has been a lot of hype about using soy milk and rice milk to replace diary. While they sound like healthy alternatives, what they really are is highly processed foods that are primarily simple carbohydrates. You are better better off doing without these as well.
Water is best, minimum one gallon a day, and herbal tea.
Avoid all soda. No coffee until you are fully recovered, if then. Fruit juices are forbidden because of their high fructose content and dumping of sugar into the blood stream. An occasional small glass of vegetable juice with a meal is o.k. If you enjoy wine or beer and still insist, there are some guidelines.
