Is the Coco de Mer the forbidden fruit?

Excuse me, could you please elaborate on the notion that the Coco de Mer is considered a forbidden fruit? I'm intrigued by the idea and would like to understand the cultural, historical, or metaphorical context behind this comparison. Are there any specific legends, customs, or taboos associated with this fruit that lend it such a mysterious status? And perhaps, if it is indeed viewed as forbidden, what are the reasons behind this perception? I'm genuinely curious to learn more.
