Is it possible to live only on vitamins and nutritional mixtures, without food? Purely hypothetically imagining that a person receives all the necessary trace elements for life

You have two questions in one. Nikolai Obukhov answered one exhaustively. But you also have a second hidden question - about the included trace elements. If your mixtures include only trace elements - after a while you will bend in order to exist - macronutrients are much more important - without them you can last from 2 to 3 months, and without trace elements, even a year or even more sometimes.

You can survive, but is it worth living then? Small premature babies "eat" like this and are pulled out. The same applies to severe patients in intensive care units who cannot eat on their own. But food consumption is not only the process of consuming micronutrients and vitamins. During meals, the necessary hormones are produced, including endorphins, the hormone of pleasure. Therefore, with this form of nutrition, you will be a living depressed person. Plus, the body will not make any reserves, because all substances will go to support the vital functions of the main organ systems.
