i know next to nothing about chocky, sugar levels etc but i do know refined sugar is known as the 'food cocanna ' of the world. Its a highly addictive food source that half the time we dont realise this. Probably more so. Im sure someone can tell you the full facts. certain sugars are good for you but refined sugars must be highly energizing hence why people eat in morning etc. Then the slippery slope starts. Big rush, big fall then more chocolate/cola n so on
I thought tea has caffine too but not as much as coffee??
