Final answer:
Mana as a concept is compared metaphorically to health food as it symbolically sustains the spirit or deep structures of the body, similar to how health food provides essential nutrients for the physical body.
Step-by-step explanation:
The idea that mana is 'like health food for our bodies' uses a metaphorical approach to compare the concept of mana as a nurturing or life-giving force to how health food nourishes the physical body. Mana, in various cultural contexts, is an abstract force believed to be a supernatural power that can be present in both people and objects. It is not a physically consumable item like food, but rather a spiritual or mystical energy that is understood to contribute to the potency or success of individuals or locations. The comparison is symbolic rather than literal, suggesting that mana and health food both provide essential sustenance, one for the soul or spirit, and the other for the physical body.
Furthermore, in a more grounded sense related to nutrition and bodily functions, health foods contribute to the energy need of the body and help maintain proper bodily functions, which can include a balanced diet providing essential nutrients, vitamins, and minerals necessary for good health and increased reproductive capability.
