Step-by-step explanation:
According to Dubisch, the symbolic oppositions found in the health food movement are purity/pollution, nature/culture, life/death, and harmony/disharmony. Therefore, the correct answer is d. all of the above. These oppositions reflect a broader cultural desire to live in a way that is consistent with the biological health needs of the human species and in greater harmony with nature.
