Why did the the arctic Indians chew on seal blubber?

Arctic Indians, including the Inuit, chewed on seal blubber primarily for its high fat content, which provided essential calories and energy needed to survive in the harsh, cold environment. The blubber is rich in nutrients and helps maintain body temperature, making it a vital food source. Additionally, chewing on blubber aided in hydration, as it contains some water content, which is crucial in a region where liquid water sources are scarce.
