JD,

I'm not an expert and I'm not going to suggest a specific product.

However, several contributors to the O board in the
past have had success with separating the fruit and carbs from
the protein and leafy veggies, and eating small meals
exclusively of one or the other. This gives the digestive
tract opportunities to work on one kind of food at a time.
That is important if the amount of digestive enzymes or gut flora
needed to do the job are still limited after a long stint of
vegetarianism.

Best wishes!
