They advise to do the riba with fat for absorption, so a lot of people use peanut butter.
My diet changed drastically on treatment. I generally do a no sugar, high on veggies, lots of fat, lots of soy, lots of fish, chicken, meat, cheese, kind of diet. Really spicy food.
During treatment, I ate ice cream and drank milk to the exclusion of any other food pretty much. It was all I could keep down, and I couldnt stand spicy food. It hurt my mouth. I gained forty lbs.
