• Food4HealthyLife 

This project is a mathematical model to estimate the life expectancy changes with a change in diet in different scenarios. We have developed an online calculator that considers the location, age, sex, weight, height, and activity level of a reference population. The model uses national mortality rates a dose-response relationship between each food group and combines them to estimate an overall gain/loss in life expectancy.
