Which formula is known for being high in calories and low in protein?

The correct answer identifies a formula that is specifically designed to provide a high-calorie content with a low amount of protein, catering to particular dietary needs. In this context, AminAid is unique because it focuses primarily on calorie-dense composition rather than protein, making it suitable for individuals who may need extra energy intake without a significant amount of protein, such as certain populations with specific metabolic needs or those undergoing treatment that necessitates a low-protein diet.

Ensure, Jevity, and Boost, while also providing nutritional support, generally offer a balance of calories and protein. Ensure is known for its comprehensive nutrition profile, Jevity is often used for patients requiring fiber, and Boost typically contains a higher protein content. This distinction helps to clarify why AminAid is the most appropriate answer in this case, as it specifically aligns with the requirement of being high in calories and low in protein.
