Was delighted to find a couple of new (well, new to me) brands of fruit-based bars at my local independent health food store. Larabar Cherry Pie (very tasty) made entirely of cherries, dates and almonds and Go Natural Fruit Medley, which comprises dried peach, apricot, apple, pear, mango and pineapple with some rice flour and non-scary preservatives.
American and Australian manufacturers lead in this area. Off the top of my head I can only recall one manufacturer, Village Bakery, that produces candida-friendly (although, it should be pointed out that these - and those referred to above - aren't specifically marketed as suitable for the diet) in the UK. And the resultant food miles really bothers me. Come on all you snack and cake bar producers - get your acts together!!!
