How can proof of health work?

Proof of health primarily relies on peer-reviewed studies published in reputable medical journals. These studies provide scientifically validated evidence, which is essential for making informed health claims. Peer-reviewed sources are considered reliable, though not perfect, and serve as a starting point for discussions on health topics 1.

In contrast, personal anecdotes, while relatable and significant on an individual level, do not serve as proof because they lack control over numerous variables. Anecdotes cannot account for confounding factors or the placebo effect, making them scientifically unreliable 1. Understanding this distinction is crucial for separating personal experiences from evidence-based health information.
