Hi Baidarka,
Alcohol is not allowed on the program. I was not a drinker so I didn’t pay attention to why that is.
There are no recommendations regarding how much whole grain foods you eat on the regular plan. If you’d like to lose weight more quickly, Dr. McDougall did outline a stricter version of the plan in a book for maximum weight loss. You’ll often see this abbreviated on this forum as MWL.
For the MWL program, instead of watching portions he advises that you eliminate flour products such as bread, pasta, and tortillas, and increase the ratio of green and yellow veggies that you eat. This should be easy for you coming from a Fuhrman plan. He also suggests that you limit rich vegan foods such as avocado, olives, soy foods, etc.
Even on the MWL plan you can eat unlimited amounts of potatoes, brown rice, millet, bulgur, oatmeal, or other whole grains. Some folks go back and forth, eating MWL during the week and then doing the regular plan on the weekends so they can have some McDougall pizza or McDougall burritos with the family on the weekend.
If you look at the list of acceptable packaged foods you’ll find a variety of soy milks in the milk alternative section.
