A generation ago, most everyday buying decisions still carried a thin layer of assumed legitimacy. A store existed, a brand existed, a seller existed, and that was often enough to move the transaction forward. Now the baseline assumption is weaker. The object might be fake. The seller might be misrepresenting it. The listing might be recycled. The review might be manipulated. The identity behind the account might be partly staged. The proof itself might be borrowed from somewhere else.

The Mediterranean diet is back, but the return itself is not new. Older food frameworks tend to resurface when newer systems become too restrictive, too optimized, or too difficult to sustain.
