In our collective imagination, cooking - especially home cooking - has always been tied to the heart, perceived as the root and symbol of the universe of sentiments. In order to innovate, "haute cuisine" must speak to the intellect, but to do so, it must firstly pass through one's emotions, so that the message it intends to convey is not left futile. To speak of the heart is to speak of health, and as such, food remains an essential element; and well-researched cuisine can demonstrate that tastefulness and healthiness can be amalgamated. Hence, this idea of taste and well-being can be spread from haute cuisine to all levels of catering, right up to industrial production.
