Hello, I'm an expert in nutrition and dietary needs. Let's dive into the question of whether one can survive on just potatoes.

Potatoes are a nutritious vegetable, rich in vitamins, minerals, and dietary fiber. They contain a good amount of carbohydrates, which are a primary source of energy for the body. However, relying solely on potatoes for sustenance would not provide a balanced diet. While potatoes do have some protein, they do not contain all the essential amino acids that the body cannot produce on its own and must obtain from food. Additionally, they are low in fat, which is necessary for the absorption of certain vitamins and for providing a concentrated source of energy. Moreover, a diet consisting only of potatoes would lack variety and could lead to deficiencies in other essential nutrients, such as vitamin A, vitamin D, calcium, and iron.

In summary, while potatoes are a nutritious food, they cannot provide all the nutrients necessary for optimal health when consumed exclusively. A varied diet that includes a wide range of foods is crucial for meeting all of the body's nutritional needs.
