Because with today’s abundance, if you only eat what naturally tastes good (sugar) you will make yourself sick. A ripe fruit was a rare bonanza back in nature, a summer and fall time delicacy to prepare for winter, no longer. https://nostr.build/av/b940709f82f5d7d24214d3789ecb7a4be70d12f0f083997b01d5a24eec3a9de2.mov

I don’t think sugar is a problem, it’s sugar in an unnatural form that is. If you ate an only fruit diet i highly doubt you would get fat. Cant say the same for an only cake diet
Modern fruits are ‘unnatural’ already, they’ve been changed by 10,000+ years of human selection to contain way more sugar and way less fiber. The point is, we evolved to “like” certain things in the context of them being very rare. In today’s abundance, only eating what your brain-of-the-scarce-past evolved for will make you sick.
Also, you might be a super taster (https://en.m.wikipedia.org/wiki/Supertaster) and just find bitter things extra offputting. Maybe what you think coffee or vegetables taste like isn’t what most people experience.
