Why is chocolate taken on antarctica expeditions?

Chocolate is actually not taken on Antarctic expeditions. It melts easily and is not as nutritious as other foods. Instead, explorers generally bring foods heavy in calories, such as energy bars, dried fruit, and nuts, to sustain them on their journey.

However, there are some reasons why chocolate might be taken on an expedition, but it is usually for recreational purposes. For example, it might be used to boost morale, provide comfort food, or celebrate special occasions.
