Some icecreams have a very high sugar content

Due to lactose intolerance some citizens cannot consume milk and other milk based products, they suffer from insomnia if they drink milk . So to get the proteins and calcium which they require, they are forced to eat ice cream.
However, there are very few icecreams which they can safely eat, because most of the icecreams have a very high sugar content.
Sandwich icecreams are easier to eat, yet they mostly have a high sugar content.
Amul had a chocolate sandwich icecream with slightly lower sugar content, yet some retailers are not having these icecreams in stock.
