SELF-CHECK

Malnutrition is a worldwide problem due to industrially processed food and due to a lack of knowledge. In order to enable people, especially children, to check the quality of their food, I developed a simple and playful self-test to check one’s own vitamin C levels. Tests for other vital vitamins and minerals are to follow. The concept is based on the fact that the body excretes surplus vitamins in urine. If the body is saturated the rest ends up in the toilet. A toilet gel serves as a colour indicator to show possible saturation. The gel dissolves with each refill, just like ordinary toilet gels. Yet, its colour changes from blue to transparent in the presence of vitamin C in the urine. Through the immediate, everyday self-test an awareness of balanced nutrition can be generated.
