Dear Mr. Anderson, Thanks for the quick reply. I am summarizing the replies and will pass them on to my client. I'm also keeping a copy for my own files--this is very important to a nutritionist, as we must often calculate kcal, protein, and fluid needs for clients and physical activity plays a big part. Again, my thanks--best regards, -- Kathrynne Holden, MS, RD Editor-in-Chief, "Spotlight on Food--nutrition news for people 60-plus" Tel: 970-493-6532 Fax: 970-493-6538 http://www.fortnet.org/~fivstar Contact Better Business Bureau of the Mountain States, < [log in to unmask]>
