Olestra, hailed as a revolutionary fat substitute, has a sinister twist: it not only fails to absorb in the body but actively leeches essential nutrients like vitamins A, D, E, and K. This fat-soluble compound also strips carotenoids from fruits and vegetables, raising alarming health concerns. Surprisingly, recent studies suggest it can even remove certain poisons from the body, making it a bizarre double-edged sword in the realm of dietary choices.
