Have you tried Original Oaten Biscuits from Duchy Originals, where profits benefit charities through The Prince of Wales's Charitable Foundation?
This product is an example of the message Prince Charles gave in his Documentary, Harmony, where I was on a conference call with the Executive Producers.
See my article on the Harmony Documentary here.
The Prince has an initiative called Dutchy Originals which acts a lot the way Newman’s Own does where natural and organic products are sold and proceeds are given to charities. Named after the Duchy of Cornwall estates, Duchy Originals was launched in 1990. Their first product, the oaten biscuit, was launched in 1992. They grew the wheat and oats themselves on Home Farm, before sending it just down the road to Shipton Mill, where they were stone-ground. As the biscuits have grown in popularity, they've expanded the number of farms used for wheat and oats. They're all from organic farms in the UK and most grow a traditional variety of wheat called Maris Widgeon - which grows unusually tall. As a result, it gives protection to native birds and insects while preventing weeds without the need for pesticides. And by the way, these biscuits are delicious!
