There is a significant amount of research that demonstrates the health benefits of vegan, vegetarian and plant-based diets, which have been associated with a reduced risk of obesity, diabetes, heart disease, rheumatoid arthritis, and some types of cancer as well as increased longevity. Here are some publications by The Nutrition Society, Journal of Nutrition and Metabolism and American Society for Clinical Nutrition.

But most of the time people don’t really decide consciously what to eat, their diet is widely determined by social and cultural factors. We eat what we learned to eat and we cook what we learned to cook, using familiar ingredients and techniques. So it's possible to suppose that sometimes unhealthy alimentary habits are the consequence of a lack of informations about healthier alternatives.

Veganizeit provides informations to specific cultural groups about the benefits of a diet without meat and dairy products and about how to veganize all the most common and loved traditional recipes.

The service could be developed as an ecosystem of technological tools, from a website to a watch app (that can also measure some body functions and track any benefit of the new diet). In general terms the service could provide the following main functions:

Impact
To motivate people to embrace changes in their alimentary habits. it’s important to show the direct impact of these changes on health (e.g. reduction of heart diseases or loss of weight). 

Traditional recipes
A collection of veganized traditional recipes organised for country/culture (e.g. in the Mexican section you could find recipes of vegan churros or burritos).

Tips
There is a vegan way to replace almost every ingredient, in this section any dairy or unhealthy food has a list of compatible replacement foods. These tips can also be provided periodically via smartphone/watch notifications or e-mail newsletter (e.g. to make a cake you can substitute 100g of butter with half mature banana).
