                                Fact: A defining characteristic of an essential nutrient is that its absence leads to deficiency diseases, a trait not found with phytochemicals or zoochemicals. This fundamental difference is why these health-promoting compounds are not officially categorized as nutrients in the traditional sense, though they are vital for optimal health.
