The macrobiotic perspective
There is the macrobiotic perspective that animal foods are extremely yang in their energetic impact on the body, contracting the energy field, and that the body will then naturally and inevitably crave foods and substances that are extremely yin and expansive. These extreme yin foods are alcohol, white sugar, drugs of most every kind, tobacco, and caffeine. Grains, legumes, and vegetables tend to be neither excessively yin nor yang, but are more balanced, and so create few cravings. Eating extreme foods forces the body to gyrate continuously between the two poles, alternatively craving contracting foods like meat, cheese, eggs, and salt, and then expansive substances like sweets, coffee, alcohol, drugs, and tobacco, ad nauseam.
