Lustig hasn't rejected "sweet fruits". He acknowledges that they're okay since they slow/retard the distribution of sugar during digestion.

There is no need to slow or retard the distribution of sugar. Insulin and your liver will deal with incoming sugars just fine. Fruit juices are a very good source of calories and minerals.

Sucrose alongside adequate nutrients to process it is good for you. Sweet fruits and honey are not to be avoided.
