Of natural flavouring, parchment paper and beet allergy

Natural flavouring is added to enhance or modify the taste of foods and beverages, and can only be made from certain edible sources. — TNS

My reason for emailing you, other than telling you your articles are very helpful, is about natural flavours. I try to only eat organic foods, so I don’t understand the reason when I see natural flavours in the ingredients. Organic stevia has natural flavourings in it. Organic crackers have it. Why? What is it? Is it all the same in everything? Is it OK to eat? I am just curious.

Thank you,
