Is root crops a go food?

Root crops are generally not considered to be a "go" food. Go foods are nutrient-rich foods that provide a high amount of sustained energy. Root crops, while containing some nutrients, are generally not as energy-dense as other types of foods that are included in the "go" category, such as fruits and whole grains. So while root crops may provide some energy, they are not considered to be an optimal choice for quick and sustained energy.
