Sugar and soda tax not taxing

Surely the writing is on the wall for much of the food and drinks industries and sugar? Just today the latest announcement that an - average - child will eat its own body weight in sugar each year. 22kg of sugar the weight of an average 5 year old imbibed through sodas and sweets and cakes. Surely progressive food an drinks industries should be detailing how and when they'll achieve zero sugar in their products? It's not taxing - but soon will be.
