Why do we require artificial sweetening agents?

(N/A) large number of people suffer from diseases such as diabetes and obesity.
These individuals cannot consume normal sugar,i.e.,$sucrose$,as it is harmful to their health.
Therefore,artificial sweetening agents are required because they provide sweetness without adding to the calorie intake of a person.
Examples of artificial sweeteners include $saccharin$,$aspartame$,and $alitame$.
