What are naturally occurring sugars?

These are the sugars naturally found in milk, fruit, vegetables and honey.

The naturally occurring sugars are lactose (milk and milk products), glucose (fresh, dried and cooked fruits, honey and most vegetables), fructose (honey, agave nectar, fruit and fruit juices) and sucrose (sugar extracted from beet or sugar cane, which is then refined and crystallised before it can be used in cooking).
