Sweetpotatoes taste fine - also raw. Nice tip from Jean-Claude. And they have nothing to do with "potatoes". Non solanin. Even normal varieties have 660 ug in 100g (while Karrots have 1800 ug about 3-fold). 800 ug beeing the recommendation. Just normal sweetpotatoes already have it in 100g. I suppose the contents in my program are scaled from beta-carotene (which is found in these plants) to real vitamin A. Btw: what i found in Erasmus' book. Beta-carotene is made of two "real" vitamin A molekules tail-tied together. I must be converted to vitamin A to become vitamin active, but *this* process could be assumed to be fairly easy. Beta-carotene has additional advantages as an antioxidant and for the bodies ability to limit its uptake to avoid vitamin A toxicity. cheers Amadeus
