In P.G. Wodehouse's book "The Gem Collector," a character reflects on Nebuchadnezzar's vegetarian diet, suggesting that while it may have been healthy, it lacked appeal or enjoyment. This commentary hints at the idea that a diet, no matter how nutritious, can fall short if it fails to satisfy other aspects of life, such as taste or pleasure. Wodehouse uses this observation to highlight the importance of finding a balance between health and enjoyment.

This notion serves as a broader metaphor for life’s experiences, indicating that simply being well-off or healthy doesn't necessarily lead to happiness. The character's musings about Nebuchadnezzar's dietary choices evoke a lighthearted exploration of the relationship between well-being and enjoyment, emphasizing that one shouldn't compromise pleasure for the sake of health alone.
