As a nutrition expert, I can tell you that the human body is complex and requires a variety of nutrients for optimal health and function. These nutrients include proteins, carbohydrates, fats, vitamins, minerals, and water. Each of these components plays a crucial role in different bodily functions, and no single food can provide all the essential nutrients in the right proportions for long-term sustenance.

However, if we were to consider a scenario where one must rely on a single food source, we would need to look for a food that is as nutritionally dense as possible.
Potatoes, as mentioned, are a good candidate due to their relatively high nutritional value compared to other starchy foods. They are a rich source of complex carbohydrates, which provide energy, and they also contain a variety of vitamins and minerals, including vitamin C, vitamin B6, potassium, and magnesium. Additionally, potatoes have a moderate amount of protein and a good range of amino acids.

But even with their nutritional benefits, potatoes are not a complete food source. They lack certain essential nutrients that are necessary for the body to function properly. For instance, they are low in fat, which is an essential nutrient for brain health, hormone production, and cell growth. They also do not provide enough of certain vitamins and minerals, such as vitamin A, calcium, and iron, which are crucial for maintaining good vision, bone health, and oxygen transport in the blood, respectively.

Furthermore, relying solely on potatoes would mean missing out on the benefits of a diverse diet. A varied diet not only provides a wider range of nutrients but also introduces different flavors and textures, which can be important for maintaining a balanced diet and preventing nutritional deficiencies.

It's also important to consider the preparation methods of the food. Boiling, baking, and steaming are generally healthier options compared to frying, as they retain more nutrients and do not add extra fats or calories. However, even with the best preparation methods, a diet based on a single food like potatoes would still be nutritionally inadequate over time.

In conclusion, while potatoes can provide a significant portion of the nutrients needed by the human body, they cannot replace the benefits of a balanced diet that includes a variety of foods. A one-food diet, especially over the long term, can lead to nutritional deficiencies and health problems.

However, there is no known food that supplies all the needs of human adults on a long-term basis. Since Taylor is determined to follow a one-food diet, then potatoes are probably as good as anything, as they contain a wider range of amino acids, vitamins and minerals than other starchy foods, such as pasta or rice.Feb 17, 2016read more >>
