Nutrition check on the go Foodnavi helps users achieve a wholesome nutrition, whether they follow a mixed or a vegetarian diet. After entering their personal profile including gender, age, body weight and physical activity level, the program calculates an optimal ratio between the different food groups - represented in a nutrition circle. Based on the recorded food intake of a full week the app displays on a color bar whether or not the intake is optimal or if there is a need for improvement. The optimum is based on the UGB's Healthy-Eating-Index (HEI-UGB). This index differs from other scoring systems as it calculates the optimal intake amounts from the different food groups instead of being based on single nutrients. Every food group is accompanied by info material and notes about its climate impact. Foodnavi has been developed for iOS in cooperation with nutritionists and dieticians, as well as with competent institutions.
