Explanation

Rationale-Nonnutritive sugar substitute produces a sweet taste without contributing any calories. For a client with type 1 diabetes mellitus, the best recommendation for a sweetener would be a nonnutritive sugar substitute. These substitutes are considered safe and do not affect blood sugar levels, which is crucial for managing diabetes. They include aspartame, sucralose, and stevia, offer sweetness without the additional calories and carbohydrates, making them a suitable choice for individuals with diabetes. Natural honey and corn syrup, while natural, are high in carbohydrates and can cause an increase in blood sugar levels. This interferes with the titration of insulin and should be avoided.
